A-9

These two cases concem a judgment of the Montrose

County District Court which set aside orders promulgated by

the Public Utilities Commission of Colorado (PUC or

Commission) involving the design of electric power rates to be

charged by Colorado-Ute Electric Association (Colo-Ute).

We reject Colo-Ute’s claim that this appeal is moot. We

further hold, contrary to the district court’s order, that the PUC

possessed statutory authority to determine whether the tariffs

filed by Colo-Ute were just and reasonable. Moreover, the

PUC’s order that Colo-Ute’s proposed all-energy rate should be

replaced by a seasonally-differentiated demand-energy rate is

supported by adequate findings of fact and substantial evidence.

We do, however, affirm the ruling of the district court setting

aside that portion of the PUC’s order which allocated

$24,084,126 of generation fixed costs to the energy component

of the demand-energy rate design. Accordingly, we reverse in

part, affirm in part, and remand for further proceedings

consistent with this opinion.

I.

Colo-Ute generates and transmits electrical power on a

wholesale basis to 14 member rural electrical cooperatives (co-

ops), which in tum market the electrical power on a retail

basis to electrical consumers. The co-ops are consumer owned

and have representatives on the board of directors of Colo-Ute,

a non-profit corporation.

In December 1981, Colo-Ute filed Advice Letter No. 45

with the PUC. The purpose of the filing was to increase Colo-

Ute’s wholesale electric power rates and thus increase annual

revenue from the co-ops by approximately $11,120,603. At

the time Advice Letter No. 45 was filed, Colo-Ute’s pricing

A-10

scheme for its member co-ops was on a "flat" or “all-energy"

rate basis.’ This pricing method had been approved by the

PUC in February 1981. To reach its desired revenue increase,

Colo-Ute proposed increasing its all-energy rate by a uniform

12.157 percent.

A revised rate schedule became effective on January 15,

1982. As a result of a statutory provision adopted by the

legislature in 1981, which is central to a resolution of the

jurisdictional issue in this case, the Commission is without

authority to suspend the effective date of tariff changes filed

by cooperative electric associations. See § 40-6-111(4)(a), 17

C.R.S. (1984). The PUC, assuming that this statutory

provision relating to suspension had no effect on its authority

to investigate rate filings, on January 12, 1982, initiated Case

No. 6076 for the purpose of investigating the reasonableness of

the tariffs filed by Colo-Ute, and set the matter for hearing.

A number of parties intervened and participated in Case

No. 6076. Intervening parties included the co-ops, as well as

customers of the co-ops: Union Carbide Corporation, Shell Oil

Company, Exxon Company, USA (Exxon), Atlantic Richfield

Company (ARCO), and the City of Delta, Colorado. At the

hearings, Colo-Ute and some of the co-ops presented evidence

both in support of the revenue increase and in the continued

use of a flat or all-energy rate. The PUC’s staff offered

evidence generally supporting a revenue increase, but

recommended abandoning the continued use of the all-energy

rate, which the staff asserted was not "cost tracking," and

therefore, no longer appropriate for Colo-Ute.? In its place, the

staff recommended a seasonally-differentiated demand-energy

rate.” The intervening customers concurred in_ the

recommendations of the Commission’s staff.

A-11

The Commission approved the revenue increase sought by

Colo-Ute. However, it disapproved the continued use of the

all-energy rate, and ordered Colo-Ute to file "demand energy

rates for its wholesale electric customers with seasonally

differentiated demand charges and an annualized energy

[charge] on a uniform kwh basis." Decision No. C83-1176.

Intervenors ARCO and Exxon, while in general agreement

with the PUC’s ultimate findings regarding the revenue

increase and the substitution of the demand-energy ate,

objected to that part of the PUC’s decision which allocated

over $24 million in generation fixed or demand costs to the

energy component of the demand-energy rate design.

Thereupon, ARCO, Exxon, Colo-Ute, and the co-ops filed

application for rehearing, reargument, and reconsideration. In

Decision No. C83-1392, the Commission denied the application

of Colo-Ute and the co-ops and granted the application of

ARCO and Exxon in part. Decision No. C83-1176 was

modified as a result, but such modifications are not at issue.‘

Colo-Ute and the co-ops sought judicial review in the

Montrose County District Court. The appeal was assigned

Case No. 83CV218. They challenged the authority of the PUC

to commence an investigation conceming the rate increase on

its own motion. They also claimed that the Commission’s

orders with respect to rate design were arbitrary, capricious,

unconstitutional, an abuse of discretion, and not in accordance

with the law and the evidence. Finally, they moved for a stay

Or suspension of the Commission’s decisions, pending final

determination by the district court of their challenge. This

motion was granted.

ARCO and Exxon sought judicial review in the Denver

District Court of that portion of the PUC’s decisions which

A-12

allegedly had misclassified certain demand costs as energy

costs. Given the similarities of the parties in the Denver and

Montrose District Court actions, and the presence of common

quesions, the Denver District Court ordered the case

transicrred to the Montrose District Court, pursuant to C.R.C.P

98(f)(1), where it was assigned Case No. 84CV7.

Subsequently, the court consolidated the two cases for hearing.

The only issue in Case No. 84CV7 concems the PUC’s

decision to shift substantial demand costs onto the energy

portion of the demand-energy rate.

With respect to Colo-Ute’s claims in Case No. 83CV218,

the district court held, inter_alia, that: (1) The PUC does not

possess statutory authority, in the absence of a complaint, to

investigate and modify the rate design of an_ electric

cooperative association, such as Colo-Ute; (2) The PUC’s

orders conceming rate design amount to an _ unwarranted

intrusion into the management prerogative and discretion of

Colo-Ute; (3) The Commission’s findings are conclusory in

nature and are not supported by substantial evidence.* The

district court thereupon set aside that part of Decision No.

C83-1176 which required Colo-Ute to file rates and tariffs

ordered by the Commission.

In Case No. 84CV7, the district court concurred in the

arguments presented by ARCO and Exxon, finding that the

decision of the Commission to allocate over $24 million of

demand costs to energy costs was not supported by substantial

evidence or adequate findings of fact, was arbitrary and

Capricious, and resulted in an unjust and discriminatory rate.

The court set aside that portion of Decision No. C83-1176

which allocated $24 million of the demand costs to the energy

costs and further held that if this court (supreme court) were to

find lawful the Commission’s imposition of the demand-energy

A-13

rate, the PUC would be directed to allocate demand-energy

costs in accordance with the staff's cost-of-service study, as

contained in Exhibit No. 84.°

On appeal the Commission raises the following issues: (1)

Whether the Commission possesses statutory authority to

institute on its own motion a proceeding to determine whether

tariffs filed by Colo-Ute are just and reasonable; (2) Assuming

that it possesses such authority, is the Commission’s decision

relating to rate desigr vumnwarranted intrusion into the

management prerogative ui Colo-Ute, and do adequate findings

of fact and substantial evidence exist to support its decision;

and (3) Whether there is substantial evidence to support the

findings that $24 million in generation fixed costs should be

allocated to the energy component of the demand-energy rate.’

Il.

Before considering the substantive issues raised in the

appeals, we first address the claim of Colo-Ute, raised in its

answer brief, that these appeals are moot and should therefore

be dismissed.

In support of its position, Colo-Ute states that in October

1986, five months after the decision of the district court, it

filed a new wholesale rate tariff governing electric power sales

to the co-ops which became effective by operation of law on

December 1, 1986. The tariff represented a 5-percent decrease

in the all-energy rate it charged the co-ops. Colo-Ute contends _

that since the tariff supersedes the tariff which is the subject of

Case No. 6076 and these appeals, the issues raised in the

instant case are "purely academic." The PUC, ARCO, Exxon,

and Shell Westem E&P, Inc. argue to the contrary and urge us

not to dismiss on the ground of mootness.

A-14

We have previously stated that a case is not moot where

interests of a public nature are asserted under conditions that

may be immediately repeated. Page v. Blunt, 126 Colo 324,

327, 248 P.2d 1074, 1075 (1952). Under our latest

formulation of the mootness test, we have held that a case is

not moot where the controversy is one "capable of repetition,

yet evading review." ke v f itutions,

198 Colo. 407, 410 n.5, 603 P.2d 123, 124 n.5 (1979) (quoting

Roe_v. Wade, 410 U.S. 113 (1973)); Star Journal Publishing

Corp. v. County Court, 197 Colo. 234, 236, 591 P.2d 1028, -

1029 (1979).

This case is not moot because the issue of proper rate

design survives the most recent tariff filing. Colo-Ute’s 1986

rate filing retains the same flat-energy rate structure which the

Commission found objectionable, and which is at issue in the

instant appeal. Colo-Ute may have changed the level of its

rates with its most recent filing, but the level of rates has

never been a matter of dispute. In fact, the issue which has

given rise to these appeals -- the authority of the PUC to

prescribe the demand-energy rate for Colo-Ute -- presents no

less a controversy now than when the PUC first set Case No.

6076 for hearing. The lawfulness of the Commission’s orders

with respect to Colo-Ute’s rate design remains a viable legal

controversy. See New England Tel

Public Utilities Comm’n, 329 A.2d 792, 806 (Me. 1974)

(rejecting mootness argument based on new rate filing where

important issues remain to be decided); Milwaukee & Suburban

Transport Corp. v. Public Utilities Comm’n, 268 Wis. 573, 68

N.W.2d 552, 556, cert. denied, 350 U.S. 877 (1955)

(controversy presented in review proceeding not moot where

issue over method of computing depreciation of utility property

remains a continuing controversy).

A-15

In addition, Colo-Ute’s argument, if accepted, would

operate to insulate much of its activity from judicial and/or

Commission review. With the addition of section 40-6-

111(4)(a), 17 C.R.S. (1984), the PUC no longer possesses the

statutory authority to suspend the date on which a tariff filed

by a cooperative electric association becomes effective. As a

result, any new or revised tariff filed by a cooperative electric

association such as Colo-Ute becomes effective by operation of

law after the expiration of the 30-day notice period specified in

section 40-3-104, 17 C.R.S. (1984). But it takes longer than

30 days for the Commission to review a rate tariff filed by

Colo-Ute, to say nothing of the time necessary for an appeal of

a Commission decision to work its way through the judicial

system. If a cooperative could render an appeal moot merely

by filing a new tariff while an appeal is pending, the

Commission’s authority to regulate cooperative utilities would

be undermined.

Moreover, ARCO, Exxon, and Shell Western E&P, Inc.

seek an order from this court directing Colo-Ute to pay refunds

to customers who might have over paid under the all-energy

rate scheme. Refund amounts would be based on the

difference in payments made under the all-energy and demand-

energy rates.

If ARCO, Exxon, and SWEPI are entitled to refunds, an

issue we do not decide, this would preclude dismissing the

instant case On mootness grounds. It is generally the law that

claims for damages or other monetary relief automatically

avoid mootness, so long as the claim remains viable. Wright,

Miller & Cooper, Federal Practice & Procedure: Jurisdiction

Second § 3533.3 at 262 (1984). Other courts have rejected

mootness claims in analogous circumstances, where, addressing

the customer’s complaint regarding damages, they first require

| _— — _

A-16

a resolution of other issues on their merits. See, eg.

Memphis Light, Gas & Water Div. v. Kraft, 436 U.S. 1, 7-8

(1978) (although injunctive relief from utility’s termination of

service had been mooted, customer’s claim for damages saved

case challenging termination procedures from the bar of

mootness); Meyers v. Jay Street Connecting Railroad, 288 F.2d

356, 358 (2d Cir.), cert. denied, 368 U.S. 828 (1961).

Finally, Colo-Ute cites in support of its position Air

Pollution Control Comm’n_ y. Colorado-Ute Electric Ass’n, 672

P.2d 993 (Colo. 1983). In that case, Colo-Ute challenged the

validity of an air pollution control commission regulation

setting forth conduct necessary to obtain an emission permit.

Although Colo-Ute cites the case for the proposition that

"when the issues in a case have been changed by subsequent

events, this court has not hesitated to find that the case has

been mooted," Colo-Ute has glossed over the particular facts in

that case. We held in Air Pollution Control Comm’n that the

question of whether the regulation had been validly adopted

was moot, because the regulation had subsequently been

repealed. 672 P.2d at 997. By comparison, Colo-Ute’s all-

energy rate is still in use and thus an issue which gave rise to

the present controversy remains unresolved.

Having determined that Colo-Ute’s mootness claim is

without merit, we now address the substantive issues raised by

this appeal.

Ill.

In holding that the PUC lacked jurisdiction to investigate

Colo-Ute’s rate filing, the district court focused upon a

provision of the public utilities law which provides, in pan:

"Upon complaint filed by any member or customer of a

A-17

cooperative electric association or by any affected ‘public utility,

the commission shall determine whether the rate, charge, rule,

or regulation in question is contrary to this section, section 40-

3-106(1), or section 40-3-111." § 40-6-111(4)(a), 17 CRS.

(1984). Although the court made reference to a number of

other provisions in the public utilities law granting the

Commission the authority to investigate rates either upon the

filing of a complaint or upon its own motion, it concluded that

section 40-6-111(4)(a):

[Pjermits that authority only upon the filing of

a complaint by any member or customer of a

cooperative electric association or by any

affected public utility. Subparagraph (4)(a)

removes the power of the PUC to suspend

rates, fares, tolls, rentals, charges,

classifications, practices, rules or regulations

pending a hearing, and does not provide that

the PUC, of its own motion, may hold such

hearings.

Although other statutory provisions concem public utilities

in general, the court stated that section 40-6-111(4)(a) is a

"specific statutory provision relating to cooperative electric

associations, and must be followed." The district court relied

on a maxim of statutory construction that "where specific and

general statutes conflict, the provisions of the specific statute

prevail." In other words, section 40-6-111(4)(a) trumps all

other provisions in the public utilities law which give the PUC

the authority to investigate rates upon the filing of a complaint,

Or upon its Own motion. The cour concluded that the PUC

does not have the authority pursuant to section 40-6-111(4),

without complaint, to change the rate design of an electric

cooperative such as Colo-Ute.

A-18

We have stated on numerous occasions that where a statute -

is capable of more than one interpretation, it must be construed

in light of the apparent legislative intent and purpose. Among

the guidelines to be considered are the ends the statute was

designed to accomplish, and the consequences which would

flow from an altemative construction. If separate clauses in

the same statutory scheme may be harmonized by one

construction, but would be antagonistic under a different

construction, we should adopt that construction which results in

harmony rather than that which produces inconsistency.

Mooney _v. Kuiper, 194 Colo. 477, 479, 573 P.2d 538, 539

(1978); Travelers Indemnity Co. v. Bames, 191 Colo. 278, 283,

552 P.2d 300, 303 (1976). Two statutes conceming the same

subject matter are to be read together to the extent possible so

as to give effect to legislative intent. Peoples Natural Gas Div,

v. Public Utilities Comm’n, 698 P.2d 255, 263 (Colo. 1985).

Further, we will presume that the legislature intended a just

and reasenable result when it enacted a statute. Allen v,

Charnes, 674 P.2d 378, 381 (Colo. 1984). See also § 2-4-

201(1)(b), 1B C.R.S. (1980) ("the entire statute is intended to

be effective").

The maxim of statutory construction relied upon by the

district court is, however, wholly irrelevant where the specific

Statute itself -- section 40-6-111 -- expressly vests the PUC

with authority to investigate rates, and therefore, raises no

conflict with other provisions of the public utilities law. If the

district court had applied proper principles of statutory

construction, it would not have ignored the remainder of

section 40-6-111, particularly subsection (1), and other pertinent

provisions of the public utilities law, all of which confirm the

Commission’s power and duty to investigate tariff changes

involving utilities such as Colo-Ute. The district court should

have read section 40-6-111(4)(a), 17 C.R.S. (1984), together

A-19

with other relevant statutory provisions, including sections 40-

6-111(1), 40-6-108(1)(b), and 40-3-102, 17 C.R.S. (1984), in

light of the apparent legislative intent and purpose.

The General Assembly added subsection (4) to section 40-

6-111 in 1981. See “An Act Concerning the Public Utilities

Commission," ch. 482, sec. 2, § 40-6-111(4), 1981 Colo. Sess.

Laws 1922-1923 [codified at § 40-6-111(4)(a), 17 C.R.S. (1981

Supp.)]. The effect of the 1981 amendment was to grant to

cooperative electric associations relief from the PUC's power to

suspend rates for up to 120 days pending investigation and

hearing, see § 40-6-111(1)(b), without diminishing the PUC’s

power under existing statutes to investigate and hold hearings,

whether upon complaint or on its own motion, and to enter

remedial orders to carry out the purposes of the public utilities

law.

As a result of the 1981 amendment, when a cooperative

electric association files a tariff with the PUC, such a tariff

becomes effective at the expiration of the 30-day notice period

provided by section 40-3-104, 17 C.R.S. (1984). Therefore,

any hearing commenced by the PUC, whether on its own

motion, or upon complaint made to the PUC, pursuant to

sections 40-6-101(1) or 40-6-111, does not have the effect of

suspending the effective date of such tariffs. This is not the

case, however, with respect to other utilities in Colorado

subject to the PUC’s jurisdiction. With respect to those

utilities, the PUC still retains the power to suspend the

effective date of such tariffs. See § 40-6-111(1)(a), (b)?

It was the statutory suspension power -- not the PUC’s

power to investigate and hold hearings -- which was abolished

by section 40-6-111(4)(a) for the benefit of cooperative electric

associations. These organizations had contended that the

A-20

“regulatory lag" which accompanied the investigation and

hearing process made it difficult for them, because of the

intervening suspension period, to be adequately compensated

for the costs of inflation even if the proposed rate increase was

ultimately approved in full. See Colorado-Ute Electric Ass'n

y. Public Utilities Comm'n, 198 Colo., 534, 544, 602 P.2d

861, 867 (1979). The efforts of cooperative electric

associations to persuade the General Assembly to grant some

form of relief achieved fruition with the passage of section 40-

6-111(4)(a) in 1981. See also Advice Letter No. 45 ("Under

the provisions of {section 40-6-111(4)(a)], this rate filing

becomes effective on thirty (30) days notice -- thereby

eliminating any regulatory lag in obtaining necessary rate

relief."). The statute only eases the burden on cooperative

electric associations resulting from suspensions during the

hearing process. It does not exempt cooperative electric

associations from PUC review of tariff changes.

The court below wrongly concluded that by removing the

suspension power, the legislature also intended to limit the

Commission’s powers to investigate tariff changes, hold

hearings, and enter remedial orders. We have previously

rejected the assumption that the power to investigate and hold

hearings is inseparably tied to, and dependent upon, the

suspension power, such that removing the power to suspend

also precludes an investigation. See, ¢e.g., Public Service Co.

y. Public Utilities Comm'n, 653 P.2d 1117, 1122 (Colo. 1982)

("we decline to impose an ‘all or nothing’ requirement upon

the commission”). Moreover, section 40-6-111(2)(a), 17 C.R.S.

(1984), states that tariff changes “not so suspended” shall go

into effect after the 30-day notice period “subject to the power

of the commission, after a hearing on its own motion or upon

complaint, as provided in this article, to alter or modify the

same." Traditionally, the PUC has enjoyed broad discretion in

‘‘* tal bt, ~~ io

al ae

A-21

determining whether to suspend the effective date of newly

filed rates, while under investigation, or allow rates to become

effective (after the statutory notice period), fully or in par,

pending the outcome of an investigation.

In enacting section 40-6-111(4)(a), the General Assembly

was careful to structure the amendment in such a fashion as to

make the suspension powers inapplicable to cooperative electric

associations, while leaving such entities subject to the other

provisions of that section and the public utilities law. The

Statute expressly provides that “this subsection (4) shall not be

construed to exempt such associations from any other provision

of this section." Among those “other provisions of this

section:"” section 40-6-111(1), which grants the Commission

the power to have a hearing concerning the propriety of a

newly filed rate or changed raic, "either upon complaint or

upon its own initiative . . ."; and section 40-6-111(2)(a).

When the statuie is read in this way -- that cooperative electric

associations are exempted only from that provision relating to

the PUC’s power of suspension -- an interpretation is achieved

which gives a harmonious and consistent effect to its various

provisions.

In fact, when the last sentence of section 40-6-111(4)(a) is

read in conjunction with section 40-6-108(1)(a) and (b) and

section 40-6-111(1), it becomes possible to discem that not

only are these provisions consistent with each other, but also

that the last sentence of section 40-6-111(4)(a) lessens a

requirement in section 40-6-108(1)(b) -- thereby promoting the

legislative intent behind subsection (4) of easing the regulatory

burden on cooperative electric associations.

Section 40-6-108(1)(b) prohibits the PUC from entertaining

complaints as to the reasonableness of any rates or charges of

A-22 ,

any public utility "except upon its own motion,” or upon a

complaint signed by:

The mayor or the president or chairman of the

board of trustees or a majority of the council,

commission, or other legislative body of the

county, city and county, city, or town, if any,

within which the alleged violation occurred, or

not less than’ twenty-five customers’ or

prospective customers ef such public utility.

On the other hand, section 40-6-111(4)(a) authorizes the PUC

to determine whether a rate charged is discriminatory or

preferential "[uJpon complaint filed by any member or

customer of a cooperative electric association or by any

affected public utility .. ."

In a sense, the complaint provision incorporated in section

40-6-111(4)(a) is a counterweight to the freedom given

cooperative electric associations to increase their rates without

suspension. Although the legislature, by adding section 40-6-

111(4)(a), terminated the authority of the PUC to suspend the

effective date of a tariff filed by an electric cooperative, the

members or customers of a cooperative electric association or

affected public utility were given added protection in the form

of an eased requirement for challenging the utility’s rate

increases.

The last sentence of subsection (4) states thai "[uJpon

complaint . . . the commission shall determine. . . ." § 40-6-

111(4)(a) (emphasis added). In other words, under certain

circumstances the Commission is required to investigate a tariff

change. But nothing in subsection (4) can be interpreted as

diminishing any of the Commission’s powers under existing

a

A-23

law to investigate tariff changes and, if necessary, to prescribe

just and reasonable rates.”

Having concluded that the PUC was properly acting within

the scope of its authority, we now consider whether that

authority was exercised in a lawful manner.

IV.

The district court found "that the Commission’s action in

changing Colorado-Ute’s rate design from a flat-energy rate to

a seasonally adjusted demand-energy rate is an unwarranted

intrusion into the management prerogatives and discretion of

Colorado-Ute.". Among the reasons given by the cour were

that in 1981 the PUC approved a flat-energy rate for Colo-Ute

and no findings in Decision No. C83-1176 vitiated the 1981

order, and in the absence of evidence or findings of abuse

associated with Colo-Ute’s existing all-energy scheme, "the

Court can only conclude that the Commission is substituting its

Own personal preference in managerial matters and _ has

exceeded its statutory authority."

The adequacy of the Commission’s findings will be

discussed later in this opinion. Considering solely the issue of

managerial discretion, it is clear that the district court erred in

concluding that the Commission, in prescribing the proper rate

design for Colo-Ute, overstepped the bounds of its proper

authority. The setting of "just and reasonable rates," both as to

level and design, goes to the very essence of the Commission’s

duties under the public utilities law. See § 40-3-102, 17

C.R.S. (1984). It is precisely the Commission’s raison d’ etre

to determine and prescribe just, reasonable, non-discriminatory,

and non-preferential “rates of every public utility in this state."

Both statutory and case law demonstrate that rate-making, both

A-24

as to charge and design, is a vital part of the Commission’s

area of responsibility.

Rate-making is a legislative function. Mountain States

hone & Tel h_v Li iliti mm’n, 176 Colo.

457, 464, 491 P.2d 582, 586 (1971). Under the Colorado

Constitution, art. XXV, the legislative authority in public utility

matters has been delegated to the PUC. Mountain States

Telephone & Telegraph v. Publi ilities Comm’n, 195 Colo.

130, 134, 576 P.2d 544, 547 (1978). As such, the PUC, in

the area of utility regulation, including rate-making, has broadly

based authority to do whatever it deems necessary or

convenient to accomplish the legislative functions delegated to

it. Id.; Miller Bros. v. Public Utilities Comm’n, 185 Colo.

414, 431, 525 P.2d 443, 451 (1974).

Nowhere in title 40, C.R.S., has the legislature specifically

restricted the authority of the PUC in designing rates for

cooperative electric associations. To the contrary, the public

utilitics law imposes upon the PUC no more imperative duty

than to “adopt all necessary rates . . . and regulate all rates

. . Of every public utility of this state." § 40-3-102. No

exception is provided for cooperative electric associations.

Until the General Assembly changes the law, the Commission

possesses not only the power and authority, but also the duty

to prescribe the rates of all utilities subject to its jurisdiction.

The fact that the instant case involves rate design, as opposed

to rate increase, is irrelevant for purposes of the analysis.

After all, rate design, just as much as rate levels, could

produce unjust, unreasonable, discriminatory, or preferential

results.”

The district court held that the Commission can set aside a

rate Only where "there is a substantial showing that rate payers

Re |

A-25

are prejudiced materially . . ." and that "the rate is so

unreasonable as to be detrimental to the public interest . . .";

in all other circumstances, rate design "[is] within the realm of

sound management discretion of the public utility."

It is of course generally accepted that the management of

the utility belongs to the company. Li Ivi Vv

Public Utilities Comm’n, 653 P.2d 1117, 1123 (Colo. 1982).

The PUC may not, under the guise of rate regulation, take

over the management of the company. As to matters

specifically entrusted to management, the PUC may not assert

itself absent an abuse of managerial discretion. Id. But it has

never been the law in Colorado that rate-making is solely a

matter within the domain of management, such that PUC

involvement is triggered only following an abuse of that

discretion. Rate-making, including the designing of rates, has

long been the exclusive province of the Commission. In fact,

in a previous case where this court recognized that "[cjourts

and Commission should . . . in general, not succumb to the

temptation of assuming the role of management," we went on

to hold that “our regulatory commissions have a duty to

declare the abuse and 1 ke such orders as will give to

ratepayers the advantage of those economies in_ which

management has failed to avail itself." Colorado Municipal

League _v. Publi iliti omm’n, 172 Colo. 188, 203-04,

473 P.2d 960, 967 (1970).

The district court erred when it concluded that the

Commission’s action in ordering Colo-Ute to shift to a

demand-energy rate "is an unwarranted intrusion into the

management prerogatives and discretion of Colorado-Ute."”

A-26

We now tum to issues conceming the adequacy of the

Commission’s findings, and the sufficiency of the evidence to

support the findings.

¥.

A.

Adequacy of Commission Findings

The district court held that the “whole tenor of Decision

No. C83-1176 as it relates to rate design is one of personal

preference on the part of the Commission as opposed to

specific findings of fact which would support a new rate

design." In the court’s words:

The commission has made no such findings in

any of its decisions regarding Case No. 6076,

and a review of the record indicates that no

such findings can reasonably be made. The

bootstrap attempt to do so in Decision No.

C83-1392 makes no additional findings than

those contained in the original Decision No.

C83-1176. Nothing in the record supports the

bold faced conclusion stated by the commission

on page 3 in Decision No. C83-1392 that the

flat energy rate currently charged by Colorado-

Ute is discriminatory, preferential, creates an

advantage, or otherwise violates 40-3-106(1) or

40-3-111.

Any ultimate findings the district court was able to discern in

the PUC’s decisions, whether implied or stated, were critiqued

Pia aE Ligh WORDT, AP SE LOTTIIS < IRE AE re A ae BoB ey

Be ites Cai aK) LA i "

A-27

as “conclusive [sic] in nature and . . . not supported by any

factual findings based on the record."

The standard for judicial review of the Commission’s

decisions is govemed by section 40-6-115(3), 17 C.R.S. (1984),

which provides:

(3) Upon review, the district court shall

enter judgment either affirming, setting aside, or

modifying the decision of the commission. So

far as necessary to the decision and where

presented, the district court shall decide all

relevant questions of law and interpret all

relevant constitutional and statutory provisions.

The review shall not extend further than to

determine whether the commission has regularly

pursued its authority, including a determination

of whether the decision under review violates

any right of the petitioner under the

Constitution of the United States or the State of

Colorado, and whether the decision of the

Commission: is just and reasonable and whether

its conclusions are %# accordance with the

evidence.

We have held that this statutory provision limits the court’s

review of PUC decisions to a determination of whether the

PUC has regularly pursued its ‘authority, whether _ its

conclusions are supported by findings of fact based upon

adequate evidence, and whether the Commission has reached its

decisions by applying the appropriate constitutional and

legislative standards. R B asting of Col Inc. v

Publi iliti mm’n, 702 P.2d 746, 750 (Colo. 1985);

A-28

Public Utilities Comm’n v. Northwest Water Corp., 168 Colo.

154, 169, 451 P.2d 266, 273-74 (1969).

We have long held that the factual determinations of an

administrative body such as the PUC are entitled to

considerable deference. Trucking Co. v. li iliti

Comm’n, 745 P.2d 211, 216 (Colo. 1987). After all, a

reviewing court, since it is without the assistance of a staff,

and the expertise of the Commission, should not undertake to

duplicate the evaluation and judgment processes followed by

the PUC in arriving at its decision. Morey v. Public Utilities

Comm’n, 629 P.2d 1061, 1068 (Colo. 1981); Atchinson,

Topeka & Santa Fe Railroad Co. v. Public Utilities Comm'n,

194 Colo. 263, 267, 572 P.2d 138, 141 (1977). It is peculiarly

within the province of the PUC to decide what weight should

be accorded the evidence and to choose among conflicting

inferences that may reasonably be drawn from that evidence.

G&G Trucking, 745 P.2d at 216; Acme Delivery Service _v.

Cargo Freight System, 704 P.2d 839, 843 (Colo. 1985). When

two equally reasonable courses of action are open to the

Commission, the reviewing court should not substitute its

judgment for that of the Commission in selecting the

appropriate alternative. City of Montrose _v. Public Utilities

Comm'n, 629 P.2d 619, 623 (Colo. 1981). A_ reviewing

court’s function is limited to determining whether substantial

evidence exists in the record to supporn the PUC’s

determinations. If not, the Commission’s order must be set

aside. If so, the judicial inquiry is at an end, for the

reviewing Court is not permitted to substitute its judgment for

that of the Commission. G&G Trucking, 745 P.2d at 216.

Findings by the Commission need not be presented in any

particular form, and a necessary finding may be implied from

other findings made. Caldwell v. Public Utilities Comm'n, 200

Inc. v. Public Utilities Comm’n, 169 Colo. 56, 62, 453 P.2d

789, 792 (1969). Where the Commission purports to make

such findings, they must be discernible to the reviewing court.

Caldwell, 200 Colo. at 138, 613 P.2d at 332. Further, findings

of fact by the Commission must show which evidence it

accepts aS competent and worthy of belief, and that which it

rejects. Id.; Aspen Airways, 169 Colo. at 62, 453 P.2d at 792.

Based upon these standards we are satisfied that the

Commission’s conclusions are supported by adequate findings

of fact.

Examination of Decision Nos. C83-1176 and C83-1392

reveals that the Commission’s findings are adequate to support

its ultimate conclusion that the all-energy rate is no longer

appropriate for Colo-Ute and should be replaced in favor of the

demand-energy rate. It found, based upon the evidence

presented, that Colo-Ute’s member distribution cooperatives

exhibit a high coincidence of peak demand with the Colo-Ute

system peak demand; that Colo-Ute’s “total cost per unit of

Output has varied monthly," contrary to Colo-Ute’s position that

the all-energy rate and its resource management plan have

resulted in a uniform cost per unit of output on a monthly

basis; and that the Colo-Ute system is characterized by a

"definite surplus of base load capacity at certain times which

indicates that Colo-Ute has not achieved uniform loading of

Capacity throughout the day. This condition results in an

uneconomic under-utilization of capacity."

With respect to Colo-Ute’s resource management plan, the

-PUC found that it was not effective in that it contributed to

growth in peak demands. Further, Colo-Ute’s load curve is not

flat; Colo-Ute has not been able to make non-member sales to

fill in the valleys of its load; its load factor has deteriorated in

A-30

recent years; and given likely economic prospects in the near

and long-term, it is not expected that Colo-Ute will be better

able "to sell energy to non-members so as to use iis plants

more efficiently.” Also, significantly increased expenses

associated with Colo-Ute’s purchase of power from other

utilities to meet peak demand, and the fact that Colo-Ute is

"unable to meet its valleys on its system, indicate that its

resource management plan and associated flat-energy rate are

not working to the benefit of its ratepayers." The PUC then

found that since Colo-Ute’s total cost of generating a kilowatt

hour is not uniform over time "it follows that a flat or uniform

energy rate is not cost tracking,” and the all-energy rate

provides a distorted price signal to member systems.

In support of its adoption of the demand-energy rate, the

PUC found that a demand-energy rate is appropriate for a

utility whose members exhibit a high coincidence of peak

demand with the system peak; that as much as two-thirds of

Colo-Ute’s costs are capital related; that the demand-energy

rate, premised as it is upon the separate and _ distinct

recognition of the two major cost compenents of producing

electricity, capital and fuel, provides a more accurate price

signal than the all-energy rate, and more directly tracks costs

than an all-energy rate, as it "assigns costs more directly to the

cost causer"; that the wholesale customers of Colo-Ute are

capable of comprehending a demand and energy rate with a

fixed customer charge; and that the demand-energy rate is the

most cost tracking rate for the wholesale power charges of

Colo-Ute.

One of the fundamental principles of electric power rate

design is that rates charged should accurately reflect the

utility’s actual cost of providing service, including both capital

costs and operating expenses. We have held that the "PUC

eee Se eet eT |

eee ere al

2 PAE MOL, 9 LE ERRATA, OM AEG 8 eae ORI

A-31

must therefore set rates which protect both: (1) the nght of a

public utility company and its investors to eam a rate of retum

reasonably sufficient to maintain the utility’s financial integrity;

and (2) the right of consumers to pay a rate which accurately

reflects the cost of service rendered." Public Service Co. v.

Public Utilities Comm’n, 644 P. 2d 933, 939 (Colo. 1982).

Here, inasmuch as the Commission has made specific

findings establishing that the all-energy rate currently in place

is less able to track the cost of service than a demand-energy

rate, the Commission has complied with the _ statutory

requirement of determining whether the rate charged is

violative of sections 40-3-106(1) or 40-3-111."°

The court below erred when it concluded that "these

findings . . . are conclusive [sic] in nature and are not

supported by any factual findings based on the record.” To

the contrary, the Commission’s findings, whether explicitly

stated or implied, comply with statutory requirements that

findings be made. Moreover, these findings are adequate to

support the Commission’s ultimate conclusions regarding Colo-

Ute’s rate design.

Eviden

The district court held that "(t]he record does not support

the conclusions reached by the PUC as to the applicability of

the demand-energy rate to the Colorado-Ute system.” Further,

"[iJn short, there does not appear to be sufficient competent

evidence for the Commission to conclude that either the

demand-energy rate is most appropriate for Colorado-Ute

because of the high degree of coincidence of peaks, nor [sic]

A-32

that the demand-energy rate is the most cost tracking rate

available for Colorado-Ute.”

The standard of substantial evidence requires more than

merely "some evidence in some particulars" to support the

Commission’s decision. Home Builders Ass’n of Metropolitan

Denver v. Public Utilities Comm’n, 720 P.2d 552, 562 (Colo.

1986); Ross _v. Fire & Police Pension Ass'n, 713 P.2d 1304,

1308 (Colo. 1986). Review of the record satisfies us that there

is substantial evidence to support the Commission’s ultimate

conclusions that (1) the demand-energy rate is the most cost

tracking rate for the wholesale power charges; and (2)

"Colorado-Ute [should] file demand-energy rates for its

wholesale electric customers with seasonally differentiated

demand charges and an annualized energy on a _ uniform

kilowatt basis as hereinafter ordered.” Without discussing all

of the evidence in detail, we will refer to the most significant

presentations put before the Commission.

The Commission heard testimony from Dr. William Leehr,

professor of economics and expert in the area of rate design.

Loehr testified ‘#ot "rates should track costs as closely as

possible." Further, to properly reflect costs, "rates should be

based theoretically upon marginal costs,” Le., the social costs

of increasing or decreasing the supply of that commodity.

Since the calculation of marginal costs for utilities is difficult,

however, Loehr testified that "[t}he direct application [to

utilities} of marginal cost pricing is often not practical.”

Rates based upon separate charges for demand and energy

costs, or demand-energy rates, recognize that there are two

major components to the cost of producing energy: (1) fixed

Capital expenses associated with the generation and transmission

of electricity (demand costs); and (2) variable operating and

A-33

maintenance expenses consisting primarily of fuel costs (energy

costs). In Colorado, utilities, particularly Colo-Ute,

predominantly use coal-fired plants. Therefore, fuel costs

represent the cost of coal, which is low in comparison with oil

or gas. Capital costs, however, tend to be relatively high,

since it is more costly to build coal-fired facilities than oil or

gas-fired ones. All utilities face trade-offs among costs. Loehr

testified that “the trick for utilities is, over the long run, to

choose that combination of capital . . . and fuel costs which

together imply minimum total cost.”

An exhibit sponsored by the president of Colo-Ute, for

example, revealed that "fof] the total costs that must be

recovered by ([Colo-Ute], approximately two-thirds are

associated with the cost of capital and one-third with the cost

of fuel and purchase power." In effect, Colo-Ute has “incurred

the high capital cost of coal-fired generation units to take

advantage of low fuel costs."

The Commission staff's cost-of-service study, which was

uncontroverted, and which was the only cost-of-service study

offered, also demonstrates that Colo-Ute incurs these two types

of costs, demand and energy, in supplying electricity. The

cost-of-service study also indicates that approximately 56

percent of Colo-Ute’s costs are fixed capital (demand) costs,

and the remaining 44 percent are fucl and similar variable

(energy) costs.

Lochr testified that since capital is the predominant element

in Colo-Ute’s costs, it should be reflected in Colo-Ute’s rates.

For this reason, a demand charge should be a pan of Colo-

Ute’s rate structure. This demand charge would be designed to

"track," or recover, that proportion of total cost representing

Capital cost. Accordingly, Colo-Ute’s rates must include both

A-34

demand charges, to recover fixed capital costs, and energy

charges, to recover the cost of fucl and other variable

expenses. Further, it was Loehr’s position that these two costs

should be segregated, and billed separately to each customer.

If not, the utility's customers receive a distorted price signal,

and do not pay a rate that tracks the actual cost of providing

electric service.

The rationale behind the demand charge, as explained by

Loehr, is that through such a charge, Colo-Ute’s customers,

i.¢., member systems, can be charged directly for their share of

the use of the Colo-Ute system’s facilities. "[A]s the system

grows, members must choose whether or not to place

increasing demands upon that system. Increased demands on

the system imply additional commitments of capital resources.

[Colo-Ute] members should face a rate structure which reflects

the cost of the capital resources that they will force [the Colo-

Ute system] to incur should they choose to increase demand.”

Other witnesses, including Warren L. Wendling, a public

utilities engineering analyst, offered testimony in which they

recommended that Colo-Ute adopt a scasonally-differentiated

demand-energy rate. Among the advantages cited were: (1)

Demand-energy raics provide an incentive to customers to

adjust their consumption pattern so that the total costs to them

are lowest and marginal costs of the system are lowest; (2) the

system would be deferring capital investments in generation

and transmission plants; and (3) other benefits lie in reduced

Capacity purchases on peak or for reserve requirements, and in

reduced operation and maintenance costs.

Moreover, the witnesses testified that any demand charges

should be seasonally differentiated, since the Colo-Ute system

peaks in the winter time, not in the summer time. The staff's

ee eee ee ot Ley

A-35

analysis based on an adjusted total cost-of-service shows a

significant disparity between the system's summer and winter

season costs (the summer figure is 34.545 mills per kwh; the

winter figure is 42.625 mills per kwh). Growth in peak

demand in winter is the type of growth which causes the

system to incur additional capital expenditures. "A _ higher

demand charge in winter than in summer should be used to

signal [Colo-Ute] members that their winter peak consumption

places constraints upon the capacity of the system.""*

When asked their opinions of the all-energy rate as

proposed by Colo-Ute, the rate design specialists attacked such

a scheme as failing to track costs, and therefore, failing to

properly reflect the costs of service. In Lochr’s words:

I do not believe the flat energy rate to be based

upon sound principles and therefore I cannot

recommend _ it. The flat energy rat is

constructed as if the only cost of generating

and supplying electricity were fucl costs. Since

fuel costs are only a small part of total costs, a

flat energy rate conveys a distorted price signal.

As I mentioned before, the main costs are the

costs of capital. A flat energy charge conveys

a signal to the members and their ultimate

customers to conserve energy. It conveys no

signal related to how they conserve energy. If

energy conservation occurs during off peak

periods, but energy use remains high during

peak periods, the system will still have to incur

the costs of capacity to provide power on peak,

yet use that capacity less during off peak

periods. The result of this would be that

Capacity cosis would have to be spread over

A-36

fewer kwh and the average price per kwh

would have to rise.

Wendling, when asked whether Colo-Ute’s flat-energy rate

is a "just and reasonable rate," responded that the flat-energy

rate "does not reflect how a utility is planned, constructed nor

operated. The rate does not track costs to cost causers.

Therefore the rate is not just."

The record indicates additional evidence regarding the

Colo-Ute system’s load factor and coincidence of member peak

demands with system peak demands, both of which underscore

the failings of Colo-Ute’s all-energy rate structure, and the

benef cial results which would accompany the introduction of

the demand-energy rate structure.

Colo-Ute witness Krumins contended that "the combination

of a flat energy rate and Colorado-Ute’s resource management

plan have resulted in a unifcrm cost per output on a monthly

basis, the operation of generation units at full capacity and a

flat load curve." In fact, an exhibit sponsored by Krumins,

"makes it clear that during the test year total costs varied from

3¢/kwh in January to 4.3¢/kwh in October, a 1.3¢/kwh

difference (or 43 percent); by 1982, the total cost varied from

3¢/kwh in January to 4.5¢/kwh in June, a difference of

1.5¢/kwh (or 50 percent)." On the basis of these figures, the

Commission concluded "from Colo-Ute’s own evidence that the

total cost per unit of output has varied monthly." Further,

since Colo-Ute’s total costs of generating a kwh are not

uniform over time, "it follows that a flat [or all] energy rate is

not cost tracking."

Finally, the Commission heard testimony regarding the

coincidence of peak demands within the Colo-Ute system.

After noting that "[t]he commission relied heavily upon Exhibit

94 in an attempt to show a high coincidence between the

system’s peaks and the members’ peaks,” the court below

remarked that "that exhibit does not appear to accurately track

all of the data available to determine coincidence of peaks.”

Further, the exhibit "shows that the peaks are not nearly as

coincident as believed by the commission." The Commission’s

findings on this issue, however, are also supported by

substantial evidence.

Among other pieces of information, Exhibit 94 documents

the dates, times, and monthly peak demands for Colo-Ute and

its CO-Op members during the period from November 1980

through October 1981. Working with this data, Mitchell, a

staff witness, testified that during February 1981, which is the

highest peak load month of Colo-Ute’s system during the test

year, 8 of the 10 members documented peaked during the top

5 percent of peak hours of the entire Colo-Ute system. The

exhibit further demonstrates that in February 1981, the 14-

member coincidence peak as a percentage of the maximum

demand for the system as a whole was 96.18 percent, and, in

fact, for the entire test year, in only two months did this figure

drop below 90 percent. Moreover, for all months of the test

year the Colo-Ute members had individual peaks which were

highly coincident with the Colo-Ute system peak. Further,

another exhibit submitted by Colo-Ute, and which indicates that

9 of the 14 members exhibited a coincidence in excess of 90

percent, similarly demonstrates the high coincidence of member

demands with the system peak.

The significance of all this for ‘ate design is that the

Commission heard testimony that "[iJn cases where peak

demands tend to be highly coincident, a de: .d-energy rate is

appropriate."

A-38

This evidence regarding peak demands is more than

sufficient to support the Commission’s findings on this issue.

In ignoring or casting aside Exhibit 94, the court below

exceeded the proper standard of judicial review.

The evidence put forth by Colo-Ute and the Commission

staff to support or challenge the propriety of the ail-energy rate

design was in dispute. Given the conflicting nature of the

evidence, alternate conclusions could have been reached. All

this establishes is that the Commission performed its duty by

resolving these disputed issues of fact in favor of the demand-

energy rate. The court may have disagreed with these findings

on disputed questions of fact, but ii is not within the province

of the district court to substitute its judgment for that of the

PUC on disputed questions of fact. Answerphone, Inc. v.

Public Utilities Comm'n, 185 Colo. 175, 178, 522 P.2d 1229,

1230 (1974).

Substantial evidence supports the Commission’s adoption of

the seasonally-differentiated demand-energy rate. The district

court’s rejection of the Commission’s findings constitutes an

impermissible intrusion into the PUC’s rate-making process.

Accordingly, the order of the district court in Case No.

83CV218 is reversed.

VI.

Finally, we consider the issue raised in Case No. 84CV7.

In that case, two customers of the co-ops, ARCO and Exxon

(ARCO/Exxon), sought review of that portion of the

Commission’s decision which allocated over $24 million of

generation fixed costs (demand costs) to the energy component

of the demand-energy rate.

A-39

4 The evidentiary basis for the allocation was provided by

Wendling who testified that electric utilities, in an effort to

operate in the most economical manner, construct a mixture of

base-load, intermediate, and peaking power plants. Base-load

plants (usually either coal or nuclear) are designed to run 24

hours a day and are characterized by high capital costs and

low operating costs, whereas peaking plants (usually oil-fired

or gas-fired) are designed to be operated for short periods of

time, and are characterized by low capital costs, but high

operating costs.

Fe Ee ee wT

so

Wendling was of the opinion that with respect to

generating costs only, there should be a recognition of a

utility’s greater investment in a generating plant able to bum

coal:

A utility can minimize its investment in a

generation plant by constructing oil or gas fired

generators. However, a fuel cost penalty is

increased. On the other hand a utility may

expend more capital and build a coal fired unit

and burn a lower price fuel. Therefore, this

additional investment should be recovered in the

energy charge.

He testified that one method used by utilities to address

Capacity problems resulting from a utility’s greater investment

in higher capital cost generation is the adoption of a time-of-

day rate, which recognizes the use of capacity at the time it

occurs.'” He noted that a number of obstacles stood in the

way of Colo-Ute’s adoption of a time-of-day rate, including the

increased complexity of metering and billing, and the need to

perform cost allocation studies for the distribution cooperatives.

Wendling conceded that the PUC staff had failed to request the

A-40

data necessary to formulate or propose such a rate for

Colorado-Ute.

As a surrogate for this time-of-day rate which he believed

appropriate for the Colo-Ute system, and to compensate for the

recognized insufficiencies regarding time-of-day rate data,

Wendling proposed a modification of the basic demand-energy

rate. This surrogate would be created by shifting to the energy

component of the demand-energy rate $24,084,126 of demand

costs representing the "average" portion of the “average and

excess demand (AED)" allocation.”

Wendling testified that since the average demand

component of the AED allocation is analogous to the base-load

portion of generating capacity -- the costs of which are

recovered through the energy charge under time-of-day rates --

the average demand component should, therefore, be recovered

in the energy charge. As the Commission described this

modification: "Mr. Wendling testified that for the Colorado-

Ute system, the amount so calculated approximated very

closely the dollars of base-load generation that would have

been spread to all hours by a time of use rate." For Colo-Ute

this average demand component, ic., the $24 million in

demand-related costs, is a surrogate for the cost of base-load

generation.

In effect, the allocation of $24 million in generated fixed

(capital) costs to be recovered under the variable (operating)

costs is a recognition of the fact that Colo-Ute, because it had

constructed only coal-fired base-load plants, was using such

plants to meet its peak, and therefore, was substituting capital

costs for operating costs in its operations. As a result of this

allocation, member cooperatives would be charged the same

A-41

rates as if Colo-Ute had originally constructed the "correct"

mixture of plants.

Relying exclusively on the time-of-day surrogate approach,

the Commission concluded that the revenue requirement

associated with base-load generation should be transferred to

the energy charge, and only the excess portion of the AED

allocation should be collected in the demand charge. The

Commission determined that piacing only the excess portion of

the AED allocation in the demand charge would provide an

automatic incentive for Colo-Ute to improve its system load

factor, since: "The higher the load factor becomes, the higher

is the proportion of generation costs collected in the energy

charge and the lower is the demand charge. This provides the

incentive to maintain and improve the system load factor that

was absent in the flat energy rate."

Because the court found that "there was no _ technical

literature to support this classification and that the witness had

conducted no research or studies which would support this

misclassification,” it concluded that the Commission’s decision

was not supported by substantial evidence and ‘was arbitrary

and capricious.

Next, the district court concluded that the Commission

failed to make adequate findings of fact to support its

classification of certain demand costs as energy costs. "[T]here

was no finding nor evidence which suggested how the shift of

the [$24 million] corresponded to the premise,” i.e., Colo-Ute’s

needing a greater investment of capital than that generally

needed for oii or gas plants.

Finally, the court held that the PUC rate is discriminatory

and establishes a preference because it requires a high-load

A-42

customer to subsidize a low-load customer, and summer users

to subsidize winter users. It reasoned that the shift of demand

cost to energy cost, which is contrary to the Commission’s

own cost-of-service study, results in an unjust and

discriminatory rate in violation of section 40-3-106.

The district court set aside that portion of the

“Commission’s order which allocated over $24 million in

demand cost to energy cost. Further, the court ruled that if the

supreme court were to set aside the district court’s order in

No. 83CV218, and, in effect, uphold the Commission’s

adoption of the demand-energy rate design, then the

Commission would be directed to adopt rates based upon the

staff’s cost-of-service study as set forth in the record.

A.

As noted above, section 40-6-115(2) and (3) limits the

district court to a narrow scope of review. Part of this review

includes determining whether the Commission’s findings of fact

are based upon substantial evidence. Ram _ Broadcasting of

Colorado, 702 P.2d at 750. Our review of the record indicates

that the Commission’s decision to shift $24 million in demand

cost to the energy component of the demand-energy rate is not

supported by substantial evidence.

After the Commission concluded, based upon the cost-of-

service study, that the seasonally-differentiated demand-energy

rate is necessary and appropriate for Colo-Ute, it disregarded

the rates dictated by that same cost-of-service study and

Classified certain demand costs as energy costs in the rates

finally adopted. Although the cost-of-service study revealed

that 56 percent of Coiv-Ute’s costs were demand related and

44 percent energy related, the Commission then adopted

err ierrrerrrneermnnniiimaieieaiiililill

A-43

Wendling’s recommendation to transfer a substantial amount of —

Colo-Ute’s demand costs to the energy component of the rate,

thereby assigning ultimately 32 percent of the utility’s costs to

the demand component, and 68 percent to the energy

component. This change represents a shift from demand to

energy of approximately 24 percent of the utility’s actual costs.

During the hearing, Wendling testified that a time-of-day

rate could not be properly calculated without further data, and

that he had not asked Colo-Ute for off-peak demand billing

data so that he could actually prepare a time of use seasonally-

differentiated rate. He also stated that the surrogate-time-of-

day rate adopted by him was without suppor in_ the

Commission staff's own studies, in outside research, or in the

technical literature. The following exchange which occurred

during his cross-examination is instructive:

QUESTION: And again, what is your

authority, if there is any authority for such an

assumption?

ANSWER: I don’t believe I have an authority.

QUESTION: Okay. Have you done any --

ANSWER: Other than myself.

QUESTION: -- research on the development of

the AED allocation factor that supports this?

ANSWER: No.

A-44

QUESTION: Can you give any reference in

technical literature that you are familiar with

which indicates that, where the AED method is

characterized as being a proxy for base-load

and peaking generation?

ANSWER: Well, my previously referred to

work papers on the time-of-day design did that.

QUESTION: But as far as technical literature

which might support that approach, can you

refer me to anything which parallels your

recommendation?

ANSWER: I can’t.

When Wendling was asked whether the approach he was

recommending has ever been advocated by the Commission in

other rate cases, he responded: "Well, it might have been but

I am not familiar with them or what their intent was, or for

what purposes they were advocated.""”

Viewing the record as a whole, and in a light most

favorable to the Commission, G&G Trucking, 745 P.2d at 216;

Home _ Builders Ass’n, 720 P.2d at 560, we conclude that

Wendling’s unsupported opinion does not constitute substantial

evidence necessary to uphold the decision of the Commission.”

Home Builders Ass’n, 720 P.2d at 562-63.

B.

We have held that where an order of the Commission is

issued solely as a matter of administrative convenience, or in

the absence of sufficient investigation into pertinent

A-45

considerations, the order is arbitrary, capricious, and invalid.

City of Montrose v. Public Utilities Comm’n, 197 Colo. 119,

123, 590 P.2d 502, 505-06 (1979) (commission’s order

arbitrary and capricious, where no study commissioned

regarding cost-of-service breakdown, although study was

feasible, and no discussion in commission’s order of disparate

service cost; therefore, order issued solely as a matter of

administrative convenience), Further, orders of the

Commission which are arbitrary and capricious must be set

aside. 1 Div, v Li iliti mm’n,

698 P.2d 255, 265 (Colo. 1985); Colorado Municipal League v.

Public Utilities Comm’n, 687 P.2d 416, 419 (Colo. 1984). See

also Federal Trade Comm'n v. Crowther, 430 F.2d 510, 514

(D.C. Cir. 1970) (adoption of significant policy change without

sufficient study and explanation is arbitrary and capricious).

The same factors which cause us to conclude that the

Commission’s conclusions are not supported by substantial

evidence, also lead us to find this portion of the Commission’s

decision arbitrary and capricious. The proposed shift to

demand costs represents little more than an ad hoc and

unsupported analytical shortcut invented and adopted simply

because the necessary rate design studies had not been

performed by the Commission staff. The evidence clearly

shows that such a study was entirely feasible, had the staff

collected the necessary data. The district court, therefore, was

fully justified in holding that this portion of the Commission’s

order was arbitrary and capricious.

<

As noted above, section 40-6-109(3) imposes on the

Commission the requirement that a reported decision shall be

accompanied by findings of fact. Moreover, section 40-6-

A-46

111(4)(a) obliges the Commission to determine whether the rate

or charge issue violates sections 40-3-106(1) and -111. The

factors relied upon by the Commission must be sufficiently

clear to enable the court to engage in meaningful review of the

Commission’s decision. well v li iliti n,

200 Colo. 134, 138, 613 P.2d 328, 332 (1980).

The Commission justified its decision to shift demand costs

on the grounds that Colo-Ute makes use of coal-fired power

plants which require a greater investment of capital than is

needed for oil or gas facilities. The Commission failed to

find, however, that the specific amount of demand costs shifted

to the energy charge accurately corresponds to the incremental

additional capital costs of coal plants in comparison with oil or

gas facilities. Indeed, the Commission could not have made

such a finding since no evidence was presented on this point.

We hold that the Commission failed to conform to the

Statutory requirements that its reported § decisions be

accompanied by adequate findings of fact.

D.

Finally, section 40-3-102 imposes upon the Commission a

duty to prevent unjust discrimination in rates. Further, section

40-3-106(1) recognizes that such discrimination may manifest

itself in a number of ways. We have previously held that one

of the primary purposes of the Commission’s regulatory

scheme is "to insure that the rates charged are not excessive or

unjustly discriminatory." rell v. Ci unty of Denver,

636 P.2d 703, 711 (Colo. 1981).

ARCO and Exxon have alleged that the rate design

ultimately approved by the PUC, with its accompanying shift

A-47

in demand costs, unlawfully discriminates in two ways: (1) It

establishes a preference for winter users and, in effect, requires

summer users to subsidize winter customers; and (2) creates a

preference in rates for low-load factor customers at the expense

of high-load factor customers, who would then pay excessive

rates to subsidize preferred customers.

We need not resolve these claims, however, as_ the

Commission’s errors mandate that this portion of Decision No.

C83-1176 be set aside.

In summary, we reject Colo-Ute’s claim that this appeal is

moot. We hold that the PUC possessed statutory authority to

institute, On its own motion, Case No. 6076, to determine

whether the tariffs filed by Colo-Ute were just and reasonable.

The Commission’s order that Colo-Ute adopt a seasonally-

differentiated demand-energy rate is supported by adequate

findings of fact and substantial evidence. We affirm the ruling

of the district court setting aside that portion of the PUC’s ~—

order which classified over $24 million of demand costs as

energy costs.

Accordingly, we reverse in part, affirm in part, and remand

for further proceedings consistent with this opinion.

JUSTICE ERICKSON concurs in part and dissents in part;

JUSTICE LOHR and JUSTICE VOLLACK join in the

concurrence and dissent.

A-48

The flat or all-energy rate does not differentiate between “demand”

charges (fixed capital costs associated with the generation and transmission o/

electricity) and “energy” charges (variable operation and maintenance

expenses, especially fuel costs). Instead, it recovers all costs -- both demand

and energy -- from a uniform charge per kilowatt hour (kwh).

tN

"Cost tracking” simply means that the rates charged for public utility

service must “wack” actual costs; in other words, the utility should accurately

assign actual costs to the consumers who are causing those costs. Ideally,

the rate schedule should be designed in such a way that the consumers

receive accurate and clear price signals from the utility and adjust their

economic behavior accordingly.

ee

Under a seasonally-differentiated demand-energy rate, an electric utility

charges its customers a rate which reflects separate charges for demand and

energy costs. Such a demand-energy rate provides separate and distinct

recognition to the two major cost components of producing electricity:

capital and fuel. Seasonal differentiation refers to the imposition of different

demand charges for summer and winter, reflecting the greater power load

burdens placed on generating facilities during the winter months.

ARCO, Exxon, Colo-Ute, and the co-ops thereupon filed new

applications for rehearing, reconsideration, and reargument of Decision No.

C83-1392. Colo-Ute also filed a motion to stay the filing date for rates and

tariffs under Decision Nos. C83-1176 and C83-1392. In Decision No. C83-

1561, the PUC denied the applications and Colo-Ute’s motion.

A-49

The district court found for the Commission on certain constitutional and

administrative due process claims raised by Colo-Ute. It held that the

Commission's procedures did not violate the Colorado Open Records Act,

§§ 24-72-101 to -309, 10 C.R.S. (1982), or the due process clauses of the

United States and Colorado Constitutions. Colo-Ute has not raised these

claims on appeal.

6

A cost-of-service study is a generally recognized approach for allocating

a utility's various fixed and variable costs based upon a utility's actual costs

of service.

~

The PUC urges reversal of the district court’s order. Colo-Ute and the ;

co-ops request dismissal on mootmess grounds, or, in the alternative, to affirm

the order. Intervenors ARCO, Exxon, and Shell Western E&P, Inc. (SWEPI)

(the successor in interest to Shell Oil Company), urge reversal of the district

court’s order on the jurisdictional issue and on the question of whether

substantial evidence exists to support the rate design change promulgated by

the PUC. On the issue of allocation of demand charges as energy charges,

ARCO and Exxon request affirmance of the district court's order.

In its entirety, section 40-6-111(4)(a), 17 C.R.S. (1984), reads as

follows:

The provisions of this section relating to suspension

of rates, fares, tolls, rentals, charges, classifications,

contracts, practices, rules, or regulations pending the

hearing and decision thereon shall not apply to cooperative

A-50

electric associations, but this subsection (4) shall not be

construed to exempt such associations from any other

provision of this section. Notwithstanding any other

provision of law, no cooperative electric association shall

establish, charge, or collect a discriminatory or preferential

rate, charge, rule, or regulation which would be violative

of section 40-3-106(1) or section 40-3-111. Upon

complaint filed by any member or customer of a

cooperative electric association or by any affected public

utility, the commission shall determine whether the rate,

charge, rule, or regulation in question is contrary to this

section, section 40-3-106(1), or secuon 40-3-111.

oO

Section 40-6-111(1)(a), (b), 17 C.R.S. (1984), reads as follows:

Hearing on schedules - suspension - new rates -

rejection of tariffs.

(1)(a) Whenever there is filed with the commission any

tariff or schedule stating any new or changed individual or

joint rate, fare, toll, . . .the commission has power, either

upon complaint or upon its own initiative, . . . but upon

reasonable notice, to have a hearing concerning the

propriety of such rate, fare, toll, . . . if it believes that

such a hearing is required and that such rate, fare, toll,

. may be improper.

(b) Pending the hearing and decision thereon, in the

case of a public utility other than a rail carrier, such rate,

fare, toll, rental, charge, classification, contract, practice,

rule, or regulation shall not go into effect; but the period

of suspension of such rate, fare, toll, . . . shall not extend

beyond one hundred twenty days beyond the time when

ae a ae

)

A-51

such rate, fare, toll, . . . would otherwise go into effect

unless the commission, in its discretion, and by separate

order, extends the period of suspension for a further

period not exceeding ninety days.

10

Section 40-6-111(2)(a), 17 C.R.S. (1984), provides in pertinent part:

If a hearing is held thereon, whether completed

before or after the expiration of the period of suspension,

the commission shall establish the rates, fares, tolls, . . .

proposed in whole or in part, or others in lieu thereof,

which it finds just and reasonable. ... All such rates,

fares, tolls, . . . not so suspended, on the effective date

thereof, which in the case of a public utility other than a

rail carrier, shall not be less than thirty days from the

time of filing the same with the commission, or of such

lesser time as the commission may grant,shall [sic] go into

effect and be the established and effective rates, fares,

tolls, . . . subject to the power of the commission, after a

hearing on its own motion or upon complaint, as provided

in this article, to alter or modify the same.

11

In its answer brief, Colo-Ute provides us with the legislative history of

H.B. 1441, the 1981 amendment eventually codified at section 40-6-

111(4(a). This information does not support Colo-‘"te’s position. In fact,

some of the legislative history actually supports the position of the PUC.

Govemor Richard D. Lamm’s message accompanying H.B. 1444 is

instructive on this point:

A-52

It [H.B. 1444} will allow REA rate increases to go into

effect after 30 days from the time they are filed with the

PUC, thereby eliminating costly delays presently incurred

because of the lengthy hearing procedure. Should a

complaint concerning the reasonableness of an increase

occur, H.B. 1444 stipulates that only one complainant is

necessary to require the PUC to review the new rate:

Under existing law, 25 customers or prospective customers

must complain before the PUC can intercede. ... While

streamlining the bureaucratic process for the rural electric

cooperatives in rate setting, this legislation does not

eliminate PUC control of facility development or other

consumer protections.

H.R.J. 2309, 53rd Leg., Ist Sess., 1981 Colorado (emphasis added).

For decisions of other jurisdictions holding that their state’s PUC

possesses the power and authority to regulate rate design, see, e.g., Rhode

Isiand Chamber of Commerce Fed’n vy. Burke, 443 A.2d 1236, 1237 (R.I.

1982) (commission had authority to modify rate design submitted by electric

utility); Central Main Power Co. v. Public Util. Comm'n, 416 A.2d 1240,

1247 (Me. 1980) (commission acted properly in regulating rate design

proposal submitted by utility); Cascade Natural Gas Corp. v. Davis, 28 Ore.

App. 621, 560 P.2d 301, 304 (1977) (authority to impose rate design

different from that proposed by the utility is encompassed in statutory

authority of commissioner to look after the interest of the utility’s customers,

to obtain a fair and reasonable rate and guard against discriminatory

exactions).

The district court also held that it could discover “no findings in

Decision C83-1176 which vitiates [sic] these findings previously made by the

Commission [in C81-373, in which the Commission in 1981 approved an all-

energy scheme for Colo-Ute].". The adequacy of the Commission’s findings

are discussed, infra. To the extent that the court below is imposing upon

PUC decision-making the applicability of stare decisis principles, it is in

error. We have held that:

Because of the legislative character of rate-making, the

Commission is not bound by its prior decisions or by any

doctrine similar to stare decisis. Moreover, while

consistency in administrative rulings is considered

essential, and while agency rulings are entitled to great

weight in subsequent proceedings . . . the appearance of

arbitrariness is dispelled when new findings are made, as

they were here, on the basis of new evidence and a new

record.

The term "peak demands” refers to the maximum rate of customer

electricity consumption (in kilowatts) occurring during a 15 or 20-minute

interval for any given month. The term “coincidence of peak demands”

expresses a relationship between a customer's and system's peak demands for

a particular point in time.

Section 40-3-106(1)(a), 17 C.R.S. (1984), provides as follows:

40-3-106. Advantages prohibited - graduated

schedules. (1)(a) Except wher operating under paragraph

(b) of this subsection (1), no public utility, as to rates,

charges, service, or facilities, or in any other respect, shall

make or grant any preference or advantage to any

corporation or person or subject any corporation or person

to any prejudice or disadyantage. No public utility shall

establish or maintain any unreasonable difference as to

rates, charges, service, facilities, or in any respect, either

between localities or as between any class of service. The

commission has the power to determine any question of

fact arising under this section.

Section 40-3-111(1), (2), 17 C.R.S. (1984), provides in pertinent part:

40-3-111. Rates determined after hearing.

(1) Whenever the commission, after a hearing upon its

own motion or upon complaint, finds that the rates, tolls,

fares, . . . demanded, observed, charged, or collected by

any public utility for any service, . . . or that the rules,

regulations, practices, or contracts affecting such rates,

fares, tolls, . . . are unjust, unreasonable, discriminatory,

or preferential, or in any way violate any provision of

law, . . . the commission shall determine the just,

reasonable, or sufficient rates, fares, tolls, . . . to be

thereafter observed and in force and shall fix the same by

order. In making such determination, the commission may

consider . . . factors which may affect the sufficiency or

insufficiency of such rates, fares, tolls, . . . during the

period the same may be in effect and may consider any

A-55

factors which influence an adequate supply of energy and

any factors which encourage energy conservation.

(2) The commission has the power, after a hearing

upon its Own motion or upon complaint, to investigate a

single rate, fare, toll, . . . or the entire schedule of rates,

fares, tolls, . . . of any public utility; and to establish new

rates, fares, tolls, . . . in lieu thereof.

16

Additional fuel is required as additional electric energy is consumed. A

component of the electric power rates reflecting additional fuel costs is,

therefore, also in keeping with the principle that rates should track costs.

17

A time-of-day rate varies the price of demand and/or energy over the

hours of the day. Such a rate attempts to signal to customers the various

cosis associated with generating electricity throughout various periods of the

day.

18

The “average and excess demand (AED)” allocation is a method used

for allocating demand-related costs. It allocates a portion of the demand-

related costs on the basis of “average” demand (kilowatt hour usage

throughout the year) and the remainder of the demand-related costs on the

basis of “excess” demand (the difference between the utility’s peak and

average demands).

19

Moreover, Gary Pearson [sic], Colo-Ute’s supervisor of rate and cost

analysis, testified that he could not think of “any articles conceming

utilization of this type of rate in any other wholesale rate proceeding”;

A-56

further, to his knowledge, “this rate concept [has never] ‘xen used in

Colorado before."

20

See also Electricity Consumer's Resource Council v. Federal Energy

Regulatory Comm'n, 747 F.2d 1511 (D.C. Cir. 1984). In that case, the court

reversed the adoption by the Federal Energy Regulatory Commission (FERC)

of a rate-making modification which effectively shifted demand costs to the

energy component of the electric rate in question. The court held that the

evidence failed to show that the modification would result in a rate which

was cost tacking. In the words of that court: "[T]he commission appears to

treat the demand charge like modeling clay in order to force the application

of marginal cost pricing to the energy component.” 747 F.2d at 1515.

No. 86SA244

JUSTICE ERICKSON concurring in part and dissenting in part:

I would affirm the decision of the Public Utilities

Commission of Colorado (PUC). I agree with the majority

that this appeal is not moot and that the PUC had statutory

authority to determine sua sponte whether the tariffs filed by

Colorado-Ute Electric Association (Colo-Ute) were just and

reasonable. I also agree with the majority that substantial

evidence supports the PUC’s order that Colo-Ute’s proposed

rate be replaced by a seasonally differentiated demand-energy

rate. In my view, however, competent evidence supports the

PUC’s allocation of $24,084,126, representing part of the fixed

capital costs of Colo-Ute’s coal-fired plants, to the energy

component of the formula used to determine the new sate.

Accordingly, I would reverse the trial coun and remand with

directions to affirm the PUC’s order.

The PUC’s order is supported by the testimony of Warren

L. Wendling (Wendling),| a Public Utilities Engineering

Analyst employed by the PUC. Generally, utilities em ioy

three types of power plants to meet fluctuating demand. for

electricity. Coal-fired plants typically operate continuously.

They are expensive to construct, but because of the low cost of

coal, cheap to operate. The combined generating capacity of

plants that a utility operates continuously is called the “base

load capacity" of the utility.» When the demand for electricity

exceeds the base load capacity, the utility typically uses either

oil- or gas-fired plants to satisfy the “peaks” in demand.

These plants are cheap to build, but because of the high cost

A-58

of oil and gas, expensive to operate. Contrary to industry

practice, Colo-Ute employs orily coal-fired plants to meet all of

its commitments tO power users.

As an integral pan of the PUC’s rate determination,

Wendling performed a cost-of-service study (study) to compute

the utility’s “cost of service," the total revenues required to

cover the utility’s cost of operation plus a fair return on its

investment. The “cost of service” is used to set the demand-

energy rates for each of Colo-Ute’s customers.“ The study

allocates costs to each customer by dividing Colo-Ute’s costs

into numerous categories. The costs distributed to each

Category are adjusted to provide Colo-Ute with a reasonable

rate of retum and then allocated to each customer based in part

on the customer’s consumption of electricity. Wendling’s

study was the only cost-of-service study of Colo-Ute presented

to the PUC.

In the cost-of-service study, Wendling followed gencrally

accepted cost allocation methods, such as that contained in the

NARUC Electric Utility Cost Allocation Manual. Generally

accepted allocation methods assume that a utility uses either

oil- or gas-powered plants to mect peaks in demand.

Accordingly, Wendling concluded that the study results had to

be modified to reiiect Colo-Ute’s investment in coal-powered

plants to meet peaks in demand. Colo-Ute’s use of coal-fired

plants, rather than oil- or gas-powered plants, to mect surges in

demand in excess of base load capacity results in lower fuel

costs but higher plant construction costs (capital costs). To

strictly follow the unmodified study results would defeat the

purpose of the study itself; that is, the study’s results would

not accurately track Colo-Ute’s actual cost of service.* With-

Out appropriate adjustments, the demand-energy rates would

cause non-peak users of electricity to subsidize peak users.

A-59

Accordingly, based upon his analysis of Colo-Ute’s operations

Wendling modified the results of his study by allocating

$24,086,126, the plant capital costs required to supply peak

demand, from the demand component of the demand-energy

rate to the energy component. The modification caused

customers to pay more for electricity used to satisfy peak

demands than under the unadjusted rates.°

Based on the testimony of Wendling, the PUC made the

following findings:

Wendling testified that . . . there should be

a recognition of the utilities’ [sic] investment in

thermal coal-fired generation plants. Investment

in such plants minimizes the cost of fuel

relative to investment in peaking plants with its

attendant low capacity or capital costs and high

fuel costs for fuels such as oil or gas.

. Substantial portions of [Colo-Ute’s

coal-fired units} are being used for peaking

purposes. In effect, units with high capital

costs and low running costs have been

substituted for units with low capital costs and

high running costs in meeting Colorado Ute’s

{electrical needs}. Although such capital

substitutions may accord with the national

energy policy, it _mevertheless creates an

artificially low energy charge. Moreover, no

gy tg he off neal a

load .

A-60

The PUC examined Wendling’s modification of the study

results and concluded that the allocation would enable more

accurate tracking of Colo-Ute's costs.’

Adantic Richfield Company (ARCO) and Exxon

Corporation (Exxon), two customers of Colo-Ute who will pay

higher power costs as a result of Wendling’s modification,

contend that the PUC’s decision to modify the study results is

not supported by substantial evidence. They argue that the

capital costs of the coal-powered plants are “fixed costs” and

can only be recovered in the demand variable of the demand-

energy rate and that the allocation of $24,084,126 to the

energy component of the rate was arbitrary and capricious.

Finally, they claim that the PUC’s prescribed energy rates are

discriminatory in violation of sections 40-3-102 and -106, 17

C.R.S. (1984 & 1987 Supp.).

A.

In reviewing the propriety of the PUC’s modification to the

demand-energy rate, we must consider two issues: (1) whether

the decision to modify the rate formula constituted an abuse of

discretion and (2) whether the amount of the modification was

supported by the record. Conceming the first issue, the PUC

has broad discretion in determining rates, provided the rates are

just and reasonable. Colorado Ute Elec. Ass'n, Inc. v. Public

Util, Comm'n, 198 Colo. 534, 602 P.2d 861 (1979);

Consumers’ League v. Colorado & S. Ry., 53 Colo. 54, 125 P.

577 (1912); § 40-3-102. It is the result reached, not the

method employed, which determines whether a rate is just and

reasonable. City of Montrose v. Public Util. Comm'n, 629 P.

2d 619 (Colo. 1981). Orders of the PUC are presumed to be

A-61

just and reasonable. Id, at 623. Rate-making is not an exact

science but a legislative function involving many questions of

judgment and discretion based upon a myriad of factors

including evidentiary facts, calculations, known factors, and

adjustments that may affect the relationship between known

factors. City of Montrose, 629 P.2d at 623; Colorado Ute

Elec. Ass'n, 198 Colo. at 539, 602 P.2d at 864. A reviewing

court has neither the expertise nor resources of the PUC and,

absent a clear abuse of discretion, should not substitute its

judgment for that of the PUC. Atchison, T. & S. F. Ry. v.

Public Util. Comm'n, 194 Colo. 263, 572 P. 2d 138 (1977).

In my view, the decision to modify the demand-energy ratc

formula was not an abuse of discretion. The PUC found,

based on competent evidence, that the cost-of-service study did

not accurately track Colo-Ute’s costs Secause the study's cost

allocations assumed that oil- and gas-powered planis would be

used to meet peaks in power demand. The assumption of the

study was inappropriate in this case since Colo-Ute employed

only coal-fired plants to meet peaks in energy demand. The

unmodified rates also failed io realize a policy goal of the

PUC. The rates, by not charging increased costs for electricity

used to supply peaks in demand, would not encourage Colo-

Ute’s customers to conserve energy and encourage Colo-Ute to

improve its load factor." Although the ability of the PUC to

effect social policy through rate-making is limited, Mountain

States Legal Foundation vy. Public Utilities Commission, 197

Colo. 56, 590 P.2d 495 (1979), the PUC has a duty to protect

the public from unreasonable and unjust rates and to prevent

destructive rate-making that could adversely affect the

availability of service to the public. Consolidated Freightways

Cor. v. Public Util. Comm'n, 158 Colo. 239, 406 P.2d 83

(1965); see Consolidated Gas Supply Corp. v. Federal Power

Comm'n, 520 F.2d 1176 (D.C. Cir. 1975) (holding federal

A-62

power commission's adoption of new rate formula, shifting a

greater proportion of capital costs from the demand component

to the commodity component of the rate formula, to be just

and reasonable where the modification was supported neither

by technical research nor by commission studies); Fuels

Research Council, Inc. v. Federal Power Comm'n, 374 F.2d

842 (7th Cir. 1967) (recognizing federal power « ~ nission’s

broad discretion in using rate formulas to achieve policy

goals); State Corp, Comm'n vy. Federal ower Comm'n, 206

F.2d 690 (8th Cir. 1953) (affirming power commission's

adoption of new rate formula that was supported neither by

technical literature nor by commission studics or rescarch), cert.

denied, 346 U.S. 922 (1954). Considering the innumerabic

factors that must be identified and quantified to determine

rates, scientific precision in rate-making is not always possible

and the PUC must be accorded broad discretion in setting

rates. Accordingly, since the impact of the modified rate on

Colo-Ute and its customers is just and reasonabic, the

moditication of the rate was not an abuse of discretion.

The second issue raised by ARCO and Exxon is whciher

the amount of the modification, $24,084,126, is supported by

the record. Section 40-6-115(3), 17 C.R.S. (1984), limits the

scope of judicial review to determinations whether a PUC

decision is unconstitutional, “whether the decision . . . is just

and reasonabic,” and “whether its conclusions are in accordance

with the evidence.” It is well established that the findings and

conclusions of the PUC on disputed questions of fact, when

Sanne GE CONGMINE GHNEINE, are final and must be upheld on

judicial review.” See, ¢.g., Mellow Yellow Taxi Co. v. Public

Util, Comm'n, 644 P.2d 18 (Colo. 1982); Contact-Colorado

Springs, Inc. v. Mobile Radio Tel. Serv., Inc., 191 Colo. 180,

A-63

551 P.2d 203 (1976). While the factual findings of the PUC

need not be presented in any particular form and may even be

implied, the findings must be discernible to the reviewing

coun. Caldwell v, Public Util. Comm'n, 200 Colo. 134, 613

P.2d 328 (1980).

In my view, the amount of the modification is supported

by competent evidence and must be upheld ori review. Based

upon his analysis of Colo-Ute’s operation and his calculations,

Wendling stated that a modification of the rate formula in the

amount of $24,084,126 was necessary to permit accurate

tracking of Colo-Ute’s costs."° Although a time-of-day rate

would also have enabled accurate tracking of Colo-Ute’s costs,

Wendling testified that that rate would be much more difficult

to implement and would provide less accurate results.

Accordingly, the modification of the demand-energy rate must

be upheld on review.

Finally, ARCO and Exxon contend that the PUC’s

prescribed energy rates are discriminatory in violation of

sections 40-3-102 and -106, 17 C.R.S. (1984 & 1987 Supp.).

They claim that the PUC’s modifications to the demand-energy

rate do not accurately track actual costs and are discriminatory

because they cause some users to subsidize rates of other users.

They argue that the modified rates (1) favor winter users and

discriminate against summer users and (2) favor customers with

fluctuating demand for electricity during the year and

discriminate against those customers with relatively constant

demand each year.

Section 40-3-102 provides that the PUC has authority “to

prevent unjust discriminations” in rates, charges, and tariffs.

A-64

(Emphasis added.) Section 40-3-106(1) states uiat “no public

utility shall . . . make or grant any preference or advantage to

any corporation or person or subject any corporation or person

to any prejudice or disadvantage" and that no utility "shall

establish or maintain any unreasonable difference . . . in any

respect, either between localities or as between any class of

service." (Emphasis added.) In Mountain States Legal

Foundation v. Public Utilities Commission, 197 Colo. 56, 590

P.2d 495 (1979), we found a violation of section 40-3-106(1)

when the PUC ordered utility companies to provide a lower

rate to low-income elderly and low-income disabled persons

that was “unrelated to the cost or type of service provided.”

Id, at 59, 590 P.2d at 498 (emphasis added).

In this case, the modification of the demand-energy formula

is related to the actual costs of Colo-Ute to supply users and

violates neither section 40-3-102 nor -106. On the contrary,

the modification prevents non-peak users from subsidizing peak

users and avoids the type of unjust discrimination raised by

ARCO and Exxon. The unadjusted demand-energy rates

endorsed by ARCO and Exxon discriminate against certain

users since the rates do not accurately reflect Colo-Ute’s costs.

Competent evidence in the record supports the PUC’s

conclusion that the modified rates accurately reflect Colo-Ute’s

costs and therefore charge Colo-Ute’s customers fairly.

Accordingly, I would reverse the district court and remand

with directions to affirm the PUC.

I am authorized to say that JUSTICE LOHR and JUSTICE

VOLLACK join in this dissent. |

A-65

The qualifications and experience of Wendling was admitted as

evidence. Wendling has a bachelors degree in electrical engineering, a

masters degree in science, and a masters degree in business administration.

He is a registered professional engineer in Colorado with over eight years’

experience in electrical engineering. He has previously testified as an expert

witness before the PUC in other cases involving rate determinations.

No

"Base load" units are those units that are in continuous operation and

“pase load capacity" is the generating capacity of those units. Mississippi

Indus. v. Federal Regulatory Comm'n, 808 F.2d 1525 (D.C. Cir.), vacated in

part, 814 F.2d 773 (D.C. Cir.), opinion reinstated, 822 F.2d 1103 (D.C. Cir.),

cert. denied, 108 S. Ct. 500 (1987). The “generating capacity" of a power

plant refers to the maximum amount of electricity that it can generate.

Ww

Peak demand refers to demand in excess of base load capacity. The

plants used to meet peaks in demand are called “peaking plants." The

typical period of peak demand for utilities is during the winter, when energy

demand far exceeds demand during other times of the year. During non-

peak periods, den. nd is typically met by the base units, which are generally

coal powered plants. When the demand of cooperative members is less than

base load capacity, Colo-Ute sells the unused capacity to non-members.

>

The demand variable is a component used to determine the demand-

energy rate and is the sum of several components, including a generation

component. The generation component is based on total average and excess

demand (also called “Average and Excess Demand"), which is the sum of the

average demand and excess demand figures. Demand-related costs are

A-66

allocated by the generation component based on “average demand” (annual

kilowatt hour usage) and “excess demand” (difference between the utility's

peak and average demands).

Ww

Wendling testified:

The energy charge was computed [after the demand charge].

Here Staff is proposing only for generation costs to recognize

the increase[d] investment in demand related dollars made by

Colorado-Ute in its generating plant so that they can bum coal.

A utility can minimize its investment in generation plant by

constructing oil or gas fired generators. However, a fuel cost

penalty is [incurred]. On the other hand a utility may expend

more capital and build a coal fired unit and burn a lower

priced fuel. Therefore, this additional investment should be

recovered in the energy charge. To accomplish this consistent

with the cost of service methodology the average portion of

the average and excess demand allocation factor was split... .

6

Wendling testified that another way to accurately track Colo-Ute’s costs

is through a time-of-day rate. He stated that a portion of the average

demand component of the average and excess demand a!location for Colo-

Ute should be recovered in the energy charge since that component is

analogous to the base load portion of generating capacity. In time-of-day

rates, the costs of base load generating capacity are recovered through the

rate’s energy component. He stated that a similar formula was used in two

prior PUC rate determinations. According to Wendling, his rate design

tracked costs better than time-of-day rates and was much easier to

A-67

implement. The PUC and Wendling use the terms “time-of-day rate” and

"“time-of-use” rate interchangeably.

~

Other pertinent parts of the PUC order stated:

One way to address (Colo-Ute’s investment in coal fired

plants to meet peaks in demand] is by the use of a time-

of-use rate which would recognize the use of capacity at

the time it occurs.

The disadvantages of a time-of-use rate, of course, is

the increased complexity of metering and billing and the

need to perform cost allocation studies for the distribution

cooperatives. As a surrogate for such a rate, Mr.

Wendling proposed a modification of the demand-energy

rate. In this modified rate, the dollars of generation costs

associated with the average portion of the [average and

excess demand] allocation were spread into the energy

charge. Mr. Wendling testified that for the Colorado-Ute

system, the amount so calculated approximated very

closely the dollars of base load generation that would have

been spread to all hours by a ume-of-use rate.

oo

A customer's annual “load factor" is the percentage relationship of its

average daily demand (annual use/365) to its maximum daily demand.

Northern Ind. Pub. Serv. Co. v. Federal Energy Regulatory Comm'n, 782

F.2d 730 (1986). Concerning the modification of the demand-energy rate,

the PUC order stated:

A-68

. . For Colorado-Ute’s particular load shape and

seasonality, the excess portion of the AED [average and

excess demand] is a proxy for the peaking portion of the

generating facilities. This peaking capacity was allocated

on the basis of coincident peak demand recognizing that

the members exhibit a high coincidence with the

Colorado-Ute system peak. Placing only the excess

portion of the AED allocation in the demand charge

provides an automatic incentive to Colorado-Ute to

improve its system load factor since the higher the load

factor becomes, the higher is the proportion of generation

costs collected in the energy charge and the lower is the

demand charge. This provides the incentive to maintain

and improve the system load factor that was absent in the

flat energy rate. . . . This should, if applicd in

conjunction with an effective resource management pian,

produce essentially a flat rate, the very rate Colorado Ute

seeks to employ. This rate form has the additional

advantage that, in the present apniication, it comports with

the regulatory objective of rate stability.

‘©

We have also held that the Pl'C's findings and conclusions may be set

aside or modified if not supported by substantial evidence. See, e.g., City of

Montrose, 629 P.2d at 622; Public Util, Comm'n v. City of Loveland, 87

Colo. 556, 289 P. 1090 (1930). The substantial evidence standard requires a

party challenging the findings and conclusions of the PUC to carry a heavy

burden.

Substantial evidence is more than a scintilla, and must do

more than create a suspicion of the existence of the fact

to be established. “It means such relevant evidence as a

reasonable mind might accept as adequate to support a

A-69

conclusion,” . . . and it must be enough to justify, if the

trial were to a jury, a refusal to direct a verdict when the

conclusion sought to be drawn from it is one of fact for

the jury.

National Labor Relations Bd. v. Columbian E. & S. Co., Inc., 306 U.S. 292,

300 (1939) (quoting ‘cidade 4, taoiee kidibianalin

Bd., 305 U.S. 197, 229 (1938)). See generally 5 K. Davis, Administrative

Law Treatise § 29:5 (2d ed. 1984)(discussing substantial evidence standard).

In my view, the PUC’s findings and conclusions in this case are supported

by substantial evidence.

10

Wendling’s opinion that a modification in the amount of $24,084,126

was necessary was based on the staff's separation of demand functionalized

costs and revenues. See supra note 5. The $24,084,126 is the sum of the

total of the average demand portion as set forth in Exhibit 60 in the PUC

hearing.

This matter coming on for hearing this 12th day of March,

1985, and the Court receiving argument of counsel, being

advised in the parties’ briefs, reviewing the record, and being

otherwise advised in the premiscs, hereby enters the following

order:

83 CV 218

I. HI RY

Colorado-Ute Electric Association, Inc. (hereinafter referred

to as Colorado-Ute) generates and transmits electrical power on

a wholesale basis to fourteen member electrical cooperatives

A-73

(hereinafter referred to as Co-ops), which in tum, sell the

electrical power on a retail basis to electrical consumers. The

Co-ops are consumer-owned and also have representatives on

the Board of Directors of Colorado-Ute, which is a non-profit

corporation.

Colorado-Ute filed Advice Letter Number 45 with the

Public Utilities Commission (hereinafter referred to as the

Commission or PUC) on December 15, 1981, to increase its

revenue by approximately 12.157%. At this time, Colorado-

Ute’s pricing rate to its fourteen member Co-ops was on a flat

rate, that is, a flat rate per kilo-watt [sic] hours used. This

method of charging had previously been approved by the PUC

on February 24, 1981, in Decision No. C81-373. No member

co-op is charged under a demand-energy rate. As a result of

Advice Letter Number 45, the PUC instituted Case No. 6076

and set the matter for hearing.

The hearing was held over several days in October and

November of 1982, and none of Colorado-Ute’s member Co-

ops complained to the PUC about the rate increase or the

pricing rate. As a result of the hearing, the PUC granted the

request for the increase in revenue but required Colorado-Ute

to change from charging its member Co-ops on a flat rate to

requiring Colorado-Ute to institute what was called a season-

ably-differentiated demand-energy rate. As a result of the

hearings in Case No. 6076, the PUC issued Decision No. C83-

1176, dated July 26, 1983. A re-hearing was held and the

PUC issued Decision No. C83-1392 on September 7, 1983,

which denied the application for re-hearing by Colorado-Ute

and granted, in part, some of the requests filed by Exxon and

Arco. Applications for re-hearing were again filed, and by

Decision No. C83-1561, the Commission denied those applica-

tions.

A-74

On October 21, 1983, Colorado-Ute and the twelve mem-

ber Co-ops filed a petition for writ of ceniorari in the

Montrose District Court and also filed a motion for stay or

suspension of the PUC’s decisions. The motion for stay or

suspension of the Commission decisions was granted on

January 16, 1984, and a briefing schedule was then set forth

for the parties.

Il. GROUNDS FOR REVIEW

Colorado-Ute alleges that the Commission decisions

Outlined above are unlawful, arbitrary, capricious, unjust, un-

reasonable and abuse of discretion and violate their nights

under the Constitutions of the United States and the State of

Colorado and that the PUC has not regularly pursucd its

authority and has rendered decisions upon findings and

conclusions not in accordance with the law and the evidence of

record. Colorado-Ute and the member Co-ops make the

following assertions:

1. The Commission does not have jurisdiction to

investigate the filing of a tariff or schedule under C.R.S. 1973,

40-6-111(4) by a cooperative electric association where no

member or consumer of such cooperative or affected public

utility has filed a complaint, as required by Section 40-6-

111(4), which provides in part:

"Notwithstanding any other provision of law, no

cooperative electric association shall establish,

charge, or collect a discriminatory or preferen-

tial rate, charge, rule, or regulation which

would be violative of Section 40-3-106(1) or

Section 40-3-111. Upon complaint filed by any

member or customer of a cooperative clectric

A-75

association or by any affected public utility, the

Commission shall determine whether the rate,

charge, rule or regulation in question is contrary

to this section, Section 40-3-106(1), or Section

40-3-111."

C.R.S. 1973, 40-3-106 prohibits a public utility from making

any preferential or advantage or subjecting any corporation or

person to any prejudice or disadvantage. C.R.S. 1973, 40-3-

111 provides that whenever the PUC, after hearing, finds that

rates, charges, classifications, regulations or practices, etcetera,

are unjust, unreasonable, discriminatory, or preferential, or in

any way violate any provision of law or that they are insuffi-

cient, the Commission shall determine the just, reasonable or

sufficient rates, rules, regulations, etcetera, and may consider

any factors which influence an adequate supply of energy and

any factors which encourage energy conservation. This par-

ticular statute also allows the PUC, upon its own motion or

upon complaint, to investigate the matter and to establish new

rates, fares, tolls, rentals, charges, classifications rules, regula-

tions, contracts, practices, or schedules, in licu of the previous

existing matters.

Several statutes contained within the public utilities law

grant the PUC the authority and the power to conduct hearings

and investigations as to the propriety of rates, charges, clas-

sifications, etcetera, upon the filing of a complaint or on its

own motion. In contrast, this statute, 40-6-111(4)(a), permits

that authority only upon the filing of a complaint by any mem-

ber or customer of a cooperative electric association or by any

affected public utility. Subparagraph (4)(a) removes the power

of the PUC to suspend rates, fares, tolls, rentals, charges, clas-

sifications, practices, rules or regulations pending a hearing,

and does not provide that the PUC, of its own motion, may

A-76

hold such hearings. Even upon complaint, Subparagraph (4)(a)

limits the Commission's determination to whether or not the

rate, charge, rule or regulation in question is contrary to 40-6-

111, 40-3-106(1) or 40-3-111. Here we have a specific statu-

tory scheme set out by the legislature and the gencral rule is

set forth in State v. Dayhoff, et al, 609 P.2d 119 (Colo.

1980), in which the court stated:

“Finally, we adhere to the well-established rule

that where specific and general statutes conflict,

the provisions of the specific statute prevail

[citations omitted).”

While the legislature has enacted numerous general and specific

Statutory provisions relating to public utilities in general, 40-6-

111(4)(a) is a specific statutory provision relating to coopera-

tive electric associations, and must be followed. To hold

otherwise would be to create nonsense out of what appears to

the Court to be a very clear and unambiguous statute and to

defeat the obvious legislative intent of the Legislature. People

y. Meyers, 182 Colo. 21, 510 P.2d 430 (1973). The Coun

therefore finds that the PUC does not have the authority pur-

suant to C.R.S. 1973, 40-6-111 (4), without complaint as pro-

vided by statute, to change the rate design of an elective [sic]

cooperative such as Colorado-Ute.

2. Colorado-Ute argues that the PUC may not reject a

tariff by a cooperative electric association and direct the coop-

erative to file a new tariff or schedule without finding that the

original tariff or schedule was unjust, unreasonable, discrimina-

tory, preferential or otherwise in violation of the law, and

without further finding that the new tariff or schedule ordered

by the Commission is just, reasonable, non-discriminatory, non-

preferential, or not unlawful.

A-77

This particular point was addressed in Decisie~ *‘o. C83-

1392 at Page 3. This was the re-hearing order in Case No.

6076 which essentially denied the petitioner's application for

re-hearing and affirmed its previous order in Case No. 6076,

that is, its Decision No. C83-1176. At Page 3 of that Deci-

sion, the PUC rejected Colorado-Ute’s argument that the PUC

was required to find that Colorado-Ute's rate schedules were

unjust and unreasonable and that the rates ordered by the PUC

were just and reasonable, relying on the case of Aspen _Air-

ways, Inc, v. Public Utilities Commission, 169 Colo. 56, 453

P.2d 789 (1969) holding that the findings of the Commission

need not take any particular form and that certain findings of

the Commission may be implied. The Commission thereupon

made the following finding:

. since, in Colorado-Ute’s view, the record

does not contain any competent evidence that a

unit pricing rate, which charges everyone the

same cents per kilo-watt [sic] hour, is unjust,

unreasonable, discriminatory, preferential, or in

violation of the law, we shall nonetheless ex-

plicitly state that Colorado-Ute'’s rate structure

is in fact unjust, unreasonable, discriminatory,

and preferential, and that its unit pricing rate is

not cost tracking for the reasons sect forth in

Decision No. C83-1176. By the same token,

we explicitly find the rate schedule proposed by

the staff of the Commission, as a result of iis

cost-of-service study, being a demand-energy

rate with seasonally differentiated demand

charges for summer and winter and an annual-

ized energy charge on a uniform kwh basis, is

more nearly cost tracking than that proposed by

A-78

Colorado-Ute, and accordingly, the staff rate is,

in fact, just and reasonable and should be

adopted."

The whole tenor of Decision No. C83-1176 as it relates to rate

design is one of personal preference on the part of the Com-

mission as opposed to specific findings of fact which would

support a new rate design. The essence of the PUC findings is

that the seasonally differentiated demand-energy rate, based on

the PUC staff's cost-of-service study, is more cost tracking,

provides an accurate price signal, and will encourage a more

effective resource management plan. The apparent basis for

requiring the implementation of a demand-energy rate is found

at Page 16 of Decision No. C83-1176 wherein the Commission

found that the Colorado-Ute members exhibit a high coinci-

dence of demand with the Colorado-Ute system peak and there-

fore demand-energy rates are appropriate for Colorado-Ute.

The Commission found that because the total cost per unit of

Output vanes monthly, that this condition resulted in an un-

economic under-utilization of capacity.

In coming to this conclusion, the Commission ignored the

evidence presented by Colorado-Ute and the member Co-ops

that a combination of a flat energy rate charge and proper

resource management will have the same effect. The Commis-

sion did not accept the notion that the overall economic condi-

tions, such as the recession and surplus energy in the region

has made Colorado-Ute less able to sell energy to non-mem-

bers so as to more effectively use its plants, however, the

Commission stated that these factors were impondcrable at best.

However, this ignores C.R.S. 1973, 40-3-111(1) which provides

in part:

A-79

. . . any may consider any factors which influ-

ence an adequate supply of energy and any

factors which encourage energy conservation."

Strangely, the Commission, at Page 22 of its Decision in C83-

1176 found that the use of the demand-energy rate, if applied

in conjunction with an effective resource management plan,

would produce essentially a flat rate, the very rate Colorado-

Ute seeks to employ. The Commission further stated that this

rate form would have the additional advantage of rate stability

which is a regulatory objective.

There does not appear to be any evidence to support that

conclusion, and on the contrary, it is difficult to conceive a

more stable rate than the flat energy rate currently used by

Colorado-Ute. Since the result of the proposed energy-demand

rate sought to be instituted by the Commission, in conjunction

with an effective resource management plan, is essentially a

flat rate, it is extremely difficult to see why the flat energy

rate currently employed by Colorado-Ute, in conjunction with

an effective resource management plan, needs to be changed.

Based upon the Commission’s findings contained in Decision

No. C83-1176, it is clear that the Commission has simply

preferred its own rate design over that employed by Colorado-

Ute, and as such, should be set aside. The Colorado Supreme

Court in Public Utilities Commission v lorado_Motorw

Inc., 165 Colo. 1, 437 P.2d 44 (1968) stated that:

"There is no question, as an abstract proposition

of law, that the Commission has broad constitu-

tional and statutory authority. However, the

breadth of that authority is to be tested by the

Statutes themselves and not by the unbridled

whim of the Commission. The Commission is

A-80

a creature of statute. Both the power and the

scope of its authority and its procedures are

necessarily controlled by the act upon which it

relies."

C.R.S. 1973, 40-6-111(4), specifically provides:

"The Commission shall determine whether the

rate, charge, rule, or regulation in question is

contrary to this section, Section 40-4-106(1) or

Section 40-3-111."

The Commission has made no such findings in any of its

decisions regarding Case No. 6076, and a review of the record

indicates that no such findings can reasonably be made. The

bootstrap attempt to do so in Decision No. C83-1392 makes no

additional findings than those contained in the original Decision

No. C83-1176. Nothing in the record supports the boldfaced

conclusions stated by the Commission on Page 3 in Decision

No. C83-1392 that the flat energy rate currently charged by

Colorado-Ute is discriminatory, preferential, creates an advan-

tage, or otherwise violates 40-3-106(1) or 40-3-111. Further, it

appears that the requirement by the Commission that Colo-

rado-Ute implement a new rate design was of its own motion,

based on staff recommendations without the filing of a com-

plaint by any member or customer of a cooperative electric

association or by any affected public utility. The Court does

agree with the Commission that Colorado-Ute can hardly claim

Surprise after going through several days of hearing [sic] when

it appears from the record that the question of rate design was

the primary concern, however, that does not alter the statutory

requirement that a complaint must be filed. Therefore, the

Court finds that the Commission improperly considered the rate

design which was not requested by Advice Letter No. 45.

A-81

Findings 1 and 5 on Page 22 of Decision C83-1176 are the

closest thing to findings which would support the Commis-

sion’s decision pursuant to 40-3-106(1), being that Colorado-

Ute’s costs are not uniform at all levels of output, and that the

demand-energy rate more directly tracks cost than a flat rate.

However, there is no finding that this is an unreasonable dif-

ference as to rates or charges between localities or class of

service. As outlined earlier, based on the Commission’s own

findings, either rate design coupled with an effective resource

management plan will produce essentially the same result. The

record does not support the contention that any such findings

pursuant to 40-3-106, 40-3-111 or 40-6-111 can be made, and

the Commission made no such findings.

The Court does agree with the Commission in Decision

No. C83-1392 that certain findings of the Commission may be

implied, and the fact that the Commission did not specifically

determine that the demand-energy rate ordered by the Commis-

sion was just, reasonable or sufficient is of no particular conse-

quence. The whole tenor of Decision No. C83-1176, is that

the Commission felt that its proposed rate design was just,

reasonable and sufficient, however, these findings, both implied

and stated, are conclusive in nature and are not supported by

any factual findings based on the record.

Colorado-Ute argues that, while the Commission found that

the revenue increase sought by Colorado-Ute was reasonable

and should be granted, that the new rate design did not take

into consideration whether or not they would be sufficient

pursuant to 40-3-111. The rate design and rate proposed by

the Commission failed to take into account the uncontroverted

testimony that the proposed rate would raise revenue when

Colorado-Ute’s monthly costs are at its lowest point and lower

the rates when its monthly costs are highest. The Commission

A-82

found that the TIER of 1.31 would be reasovzable and that ‘he

proposed rate design and rate would provide Colorado-Ute with

a margin of safety in meeting its indenture requirements, how-

ever, there is nothing in the record to indicate how this would

be done. The expectation, of course, is that this would aver-

age out over a calendar year, but does not take into account

the financial difficulties which apparently would be encountered

by Colorado-Ute in the summertime, resulting in increased

short-term borrowing by Colorado-Ute. This also did not take

into account the increased costs associated with a changed

billing procedure and acquisition of equipment and meters

necessary to implement the changeover. There is no indica-

tion, except conjecture, that such rates would be sufficient and

would allow Colorado-Ute to achieve the TIER level.

3. Colorado-Ute next argues that the Commission may not

disregard the convenience and preference of Colorado-Ute and

its member Co-ops in designing rates for electrical service by

substituting the Commission’s own rate design.

In this case, Colorado-Ute by its Advice Letter No. 45 was

not seeking to change its existing rate design, but merely seek-

ing an increase in that rate. The record is clear that Colorado-

Ute and all member co-ops which provided testimony before

the Commission supported a unit pricing rate, that is, the flat

energy rate. People’s National Division v. Publi iliti

Commission, 193 Colo. 421, 567 P.2d 377 (1977) notes that

unless there is a substantial showing that rate payers are preju-

diced materially by the managerial options in the area of capi-

tal financing, such matters are within the realm of sound man-

agement discretion of the public utility. That case dealt with

Capital financing as opposed to rate design, however, the prin-

ciple remains the same. Although an old case, this principle

was also followed in Refining Co. v Public Utilities Commis-

A-83

sion, 68 Colo. 137 (1920), determined that the cancelling of an

existing rate in a contract could only be done if the Commis-

sion determined that the contract rate was detrimental and

injuriously affected the public welfare. That case requires the

Commission to determine that the rate is so unreasonable as to

be detrimental to the public interests before the Commission

may establish the new rate. Even in this case, the court was

talking about the rate as opposed to a new rate design. Also

see 73B C.J.S., Public Utilities, § 19. There is no evidence of

a substantial showing that the rate payers are being materially

prejudiced by the unit pricing rate and apart from the staff, as

Outlined earlier, only the intervenors such as Union Carbide

and Exxon, which would benefit from the new rate design,

opposed the unit pricing rate.

The Commission ignored substantial testimony in the record

by the member Co-ops in which they testified that if Colorado-

Ute were forced to charge them on an energy-demand rate,

they in tum would have to charge their consumers on the same

basis. Not only would this necessitate a change in billing and

metering by Colorado-Ute, and therefore increase the cost, but

the same eifect would apply to the member Co-ops and the

end use consumer. This, contrasted against the questionable

benefits of going to an energy-demand rate does not support

the Commission’s findings.

The Court finds that the Commission’s action in changing

Colorado-Ute’s rate design from a flat energy rate to a season-

ally adjusted demand-energy rate is an unwarranted intrusion

into the management prerogatives and discretion of Colorado-

Ute. The Commission itself in Decision No. C81-373, Febru-

ary 24, 1981, approved a flat energy rate for Colorado-Ute.

Page 4 of that Decision recites several findings made by the

Commission in this regard and the Commission in that Deci-

A-84

sion notes that the costs to Colorado-Ute to generate power are

basically constant and uniform, and that a flat energy rate

would recover both the demand cost and the energy cost on

the basis of usage. The Court can find no findings in

Decision No. C83-1176 which vitiates these findings previously

made by the Commission, and although the Commission has

general authority to correct managerial abuses of discretion

which adversely or injuriously affect the public interest, no

such findings have been made. As stated in Public Service

Co. v. Public Utilities Commission, 653 P.2d 1117 (Colo.

1982), the management of the public utility belongs to the

company. And where, as here, there is no evidence or find-

ings of abuse, the Court can only conclude that the Commis-

sion is substituting its own personal preference in managerial

matters and has exceeded its statutory authority.

Based upon the record, it is clear that the Commission

totally ignored the evidence and the testimony presented by

Colorado-Ute and the member Co-ops conceming the flat ener-

gy rate. The Court concurs with Mr. James at Page 13 of his

brief wherein it is noted that Colorado-Ute and the member

Co-ops have had an experience factor with both a flat energy

rate structure and a demand-energy rate structure and all, with-

Out exception, from a managerial point of view, favor the flat

energy rate. This is particularly highlighted by the fact that,

while Colorado-Ute only wholesales power to the fourteen

member Co-ops, the member Co-ops retail this electrical power

to the use of the consumer. Their testimony, particularly as it

relates to an understandable pricing signal and general wants of

the public, cannot be minimized. This is particularly true since

Colorado-Ute and the fourteen member Co-ops are all non-

profit, consumer-owned, cooperatives. It is extremely difficult

to ascertain any improper motivation on the part of their col-

lective managements which would cause them to prefer a flat

energy rate. Certainly the profit motive does not exist, and it

is difficult to see any irresponsibility in their wanting to keep

the flat energy rate.

4. Colorado-Ute next argues that its right to due process

under the Fourteenth Amendment to the United States Constitu-

tion and under Article II, § 25 of the Colorado Constitution,

was violated by admitting testimony based on the WASP-82

computer analysis, and that the Commission violated C.R.S.

1973, 24-72-304 (The Colorado Open Records Act), in refusing

to provide Colorado-Ute with a copy of the WASP-82 com-

puter program.

The Court rejects this argument advanced by Colorado-Ute.

Hearings in this case were held before the Commission on

seven separate days between October 6, 1982, and ending

November 16, 1982. While Colorado-Ute is entitled to due

process as set forth in Mountain States T. and T. Co. v. De-

partment of Labor, 184 Colo. 334, 520 P.2d 586 (1974), a

review of the record discloses that Colorado-Ute did not re-

ceive information on the WASP-82 analysis and did sponsor

testimony as a result thereof. This matter was discussed at

length at the hearing date on October 26, 1982, and again on

November 15, 1982. Colorado-Ute erroneously stood on their

objection and did not cross-examine staff witness Mr. Wen-

dling, and did so at their own peril. Based upon the applica-

tion for re-hearing, the Commission in its Decision No. 1392

addressed this issue on Pages 3 and 4 of that Decision, and a

review of the record in that regard clearly substantiates the

Commission in that regard. The Court therefore finds that the

Commission neither violated the Colorado Open Records Act

nor Colorado-Ute’s right to due process under the Fourteenth

Amendment to the U.S. Constitution or Article II, § 25 of the

Colorado Constitution.

A-86

5. The record does not support the conclusions reached by

the PUC as to the applicability of the demand-energy rate to

the Colorado-Ute system.

The Commission relied heavily upon Exhibit 94 in an

attempt to show a high coincidence between the system’s peaks

and the members’ peaks, however, that Exhibit does not appear

to accurately track all of the data available to determine coin-

cidence of peaks. Page 1 of that Exhibit, listing the date and

time of occurrence of member system peaks, together with the

Colorado-Ute system peak "date hour", shows that the peaks

are not nearly as coincident as believed by the Commission. It

appears from the testimony in the record that the applicability

of the demand-energy rate to the Colorado-Ute system is only

appropriate if the peak demands are highly coincident. Further,

the testimony indicated that the demand energy rate acts as a

functional surrogate for time-of-day rates, and that time-of-day

rates are not relevant at this point in time for the Colorado-Ute

electric system. In shor, there does not appear to be sufficient

competent evidence for the Commission to conclude that either

the demand-energy rate is most appropriate for Colorado-Ute

because of the high degree of coincidence of peaks, nor that

the demand energy rate is the most cost tracking rate available

for Colorado-Ute.

Ill. NCLUSION

WHEREFORE, based upon the foregoing, the Court hereby

directs that the order of the Commission in Decision No. C83-

1176 requiring Colorado-Ute Electric Association, Inc. to file

rates and tariffs reflecting the rates set forth in Appendix B of

said order is hereby set aside and is of no force and effect.

Paragraph 3 of said order is hereby affirmed, and Colorado-Ute

Electric Association shall submit to the Commission a feasi-

bility study of a load research program as contained in the

A-87

Commission’s order. Further, the suspending bond filed by

Colorado-Ute in the amount of $500,000.00 is hereby

discharged and released.

84 CV 7

I. HISTORY

This case, 84 CV 7, was consolidated with Case No. 83

CV 218, and was docketed in the Montrose District Court on

January 12, 1984. Atlantic Richfield Co. (hereinafier referred

to as ARCO), and Exxon Corporation (hereinafter referred to

as Exxon) had filed a complaint seeking judicial review of the

Commission’s decision in Case No. 6076. A motion to dis-

miss the petitioners’ complaint was filed by several of the

intervenors and by Colorado-Ute, which motions were denied

on January 4, 1984. Because of the similarity of parties, and

because both of these cases revolved around Case No. 6076

before the Commission, venue in Case No. 84 CV 7 was trans-

ferred to the Montrose District Court and then consolidated

with 83 CV 218. The history of 83 CV 218 and 84 CV 7 are

therefore identical, and the only issue in 84 CV 7 relates to

ARCO’s and Exxon’s disagreement with the Commission’s

decision to shift substantial demand costs into the energy por-

tion of the demand-energy rate required by the Commission

and that such shift was contrary to the staff’s cost-of-service

study, which is Exhibit 84 of the record.

Il. GROUNDS FOR REVIEW

1. ARCO and Exxon argue that the Commission’s deci-

sion to classify certain demand costs as energy costs is not

supported by substantial evidence in the record.

A-88

In particular, the petitioners argue that the Commission's

shift of certain demand related cosis to the energy component

of the seasonably adjusted energy-demand rate proposed by the

staff and required by the Commission to be implemented as sct

forth in Appendix B of Decision No. C83-1176 is not sup-

ported by the evidence and the Commission's findings. Ac-

cording to the staffs cost-of-service study, approximatcly 56%

of Colorado-Ute’s costs are fixed capital costs, that is, expenses

associated with the generation and transmission of clectric

power, and 44% of the costs are operational and mainicnance

expenses, primarily fucl costs. Assuming that the demand-

energy rate proposed by the staff and adopted by the Commis-

sion is implemented, then that rate includes a demand charge

to recover fixed capital cosis and an energy charge to recover

operational and maintenance expenses, the idca being that a

separate energy charge and a separate demand charge most

accurately tracks the actual cost of electrical service for any

particular user.

In its decision, the Commission allocated $24,084,126.00 of

the average demand revenue to the annualized cnergy charge,

which, to a high energy user such as the petitioners, results in

increased cicctnical costs.

Based upon the testimony and recommendations of Mr.

Wendling, a staff witness, the Commission shificd pan of

Colorado-Ute’s demand related costs to the energy component

of their rate thereby assigning 32% of the cost to the demand

charge and 68% to the energy charge, in contrast to the cost of

service study which had determined that 56% of the costs were

demand related and 44% energy related. The record is not

clear on what basis this shift was made, and appears to be an

attempt to devise a kind of “time-of-day" rate. The witness

rrr em oe we

A-89

acknowledged that such a rate could not properly be calculated

without further data.

While exactitude and unerroring precision is not required,

guesswork and personal preference is not allowed. The record

is clear that there was no technical literature to support this

classification and that the witness had conducted no research or

studies which would support this misclassification. This is

particularly true when or. notes that such misclassification is

contrary to the cost-of-service study resulting in a reduction of

the demand related costs from 56% to 32% and an increase of

the energy related costs from 44% to 68%. As noted on Page

14 of petitioners’ brief, the existence of “some evidence and

some particulars” is insufficient if the evidence as a whole

does not support the Commission's decision. Lassner v. Civil

Service Commission, 177 Colo. 257, 259, 493 P.2d 1087, 1089

(1972) (emphasis in original). This is particularly true since

the only evidence apart from the conjecture and personal pre-

ference of Mr. Wendling is as it relates to the allocation of

costs to the demand in energy components of the demand-

energy rate, consists of the staff's cost-of-service study. There-

fore, the Coun finds that the Commission's decision in this

regard should be set aside and the Commission be directed to

adopt the cost-of-service study rates set forth in Exhibit 84.

2. The petitioners argue that the Commission’s misclas-

sification of demand costs as energy costs is arbitrary and

Capricious.

Any part of the Commission’s order which appears to be a

matter of personal preference or administrative convenience,

and without the necessary investigation and research data, may

be considered arbitrary and capricious and therefore invalid.

i Vv mmission, 197 Colo.

A-90

119, 590 P.2d 502 (1979). The Court in that case held that

there was no study done which would support the order of the

Commission, however, in this case, there was a study done, the

staff's cost-of-service study, however the basis for the misclas-

sification, contrary to the study, was not founded upon any

administrative or technical literature nor upon any research or

Studies to support the shift. As such, the Court must conclude

that the decision of the Commission to reclassify the

$24,084.126.00 [sic] of the demand costs to the energy costs

was arbitrary and capricious and without sufficient study and

foundation. Further, as noted on Page 22 of the petitioners’

bricf, the evidence indicates that such a study as proposed by

Mr. Wendling was feasible, but like the City of Montrose case,

supra. was not done.

3. The petitioners argue that the Commission failed to

make adequate findings of fact to support its misclassification

and shift of certain demand costs as energy costs.

The petitioners contend that the findings of the Commis-

sion must be sufficiently clear as to enable the reviewing coun

to engage in a meaningful review of the Commission’s deci-

sion. A review of the record shows that the primary basis for

this shift of demand costs inconsistent with the cost-of-service

study was that Colorado-Ute utilized coal-fired power plants

and therefore required a greater investment of capital than that

generally needed for oil or gas plants, however, there was no

finding nor evidence which suggested how the shift of the

$24,084,126.00 corresponded to that premise.

Since one of the primary purposes of the public utilities

law is to insure that the rates do not establish an unreasonable

difference between classes of customers and that the ratc

payers be accorded equal treatment, it is clear that this shift of

A-91

demand costs to energy costs, contrary of the cost-of-service

study, results in an unjust and discriminatory rate as it relates

to the petitioners. The practical and end result of this shift, of

course, is that the petitioners, and users like them, will pay

considerably more for their electrical power and is therefore a

preferential rate forbidden by law as set forth in C.R.S. 1973,

40-3-102 and 40-3-106. As pointed out on Pages 30 through

33 of the petitioners’ brief, the Commission's proposed rate

established a preference in that the winter customers pay rates

below the actual cost of service to them (the record shows that

Colorado-Ute is a winter peaking system) and that summer

users pay higher rates than the actual cost-of-service and there-

fore in effect subsidizes the preferential rate for winter users.

This preference is eliminated by requiring the Commission to

adopt the rates based upon the staff's cost-of-service study.

Electric customers such as the petitioners, are constant and

consistent users of electrical power, and are high-load consum-

ers. That is, their use of electrical energy is fairly constant

and is not significantly increased or decreased by summer or

winter conditions. This means that the higher the load the

lower the unit cost of electrical energy. Therefore, the mis-

classification of demand costs as energy costs significantly

increase the costs of electrical power to such consumers. Since

the rates should approximate the actual cost of service, the

PUC rate is discriminatory in nature and in effect requires a

high load consumer to subsidize a low load consumer. Moun-

197 Colo. 56, 590 P.2d 495 (1979). While exact precision is

not required as noted earlier, the enormity of this shift cannot

be justified.

A-92

III. CONCLUSION

WHEREFORE, based upon the foregoing, the Court hereby

sets aside that portion of the Commission’s order in Decision

No. C83-1176, Case No. 6076, which allocates $24,084,126.00

of the demand cosis to the energy costs, and, if the Court’s

order in 83 CV 218 is set, hereby directs the Commission to

adopt rates based upon the staff’s cost-of-service study set forth

in Exhibit 84 of the record. For the record and for clarifica-

tion, 11 of the intervenors had filed a motion to dismiss in the

Denver District Court in 84 CV 7, and the Court has not yet

formerly [sic] denied Colorado Ute’s [sic] motion to dismiss in

that case. By this order, the Court hereby denies Colorado-

Ute’s motion to dismiss.

DONE IN OPEN COURT this 7th day of May, 1986.
