Section 466.45  Pre-Application Report

a)         A

potential applicant may submit a formal written request form along with a

non-refundable fee of $300 for a pre-application report on a proposed project

at a specific site. The EDC shall provide the pre-application data described in

Section 466.50(b) to the potential applicant within 20 business days after

receipt of the completed pre-application report request form and payment of the

$300 fee. The pre-application report produced by the EDC is non-binding and

does not confer any rights; the potential applicant must file an application

before it can interconnect with the EDC's system. The written pre-application report

request form shall include the following information:

1)         project

contact information, including name, address, phone number and email address;

2)         project

location (street address with nearby cross streets, town, and GPS coordinates

in decimal format);

3)         meter

number, pole number, EDC account number or other equivalent information

identifying proposed point of interconnection, if available;

4)         generator

type (e.g., solar, wind, combined heat and power, energy storage or inverter

system, or fuel cells);

5)         total

generation capacity and total storage capacity (alternating current kVA);

6)         single

or three-phase generator configuration;

7)         whether

new electric service is required for the site. Include the existing minimum and

maximum on-site electrical demand (in kVA) and describe any expected changes to

the minimum or maximum on-site electrical demand (in kVA), including the timing

of those changes; and

8)         the number

and capacity of each generator unit to be interconnected at the site specified

in the pre-application report request

lectric service is required for the site. Include the existing minimum and

maximum on-site electrical demand (in kVA) and describe any expected changes to

the minimum or maximum on-site electrical demand (in kVA), including the timing

of those changes; and

8)         the number

and capacity of each generator unit to be interconnected at the site specified

in the pre-application report request.

b)         Using

the information provided in the pre-application report request form described

in subsection (a), the EDC will identify the distribution facilities that are

likely to serve the proposed point of interconnection if the project is

constructed, including:  substation/area bus, substation transformer or

distribution circuit, as applicable. This identification by the EDC does not

guarantee, after application of the relevant review process, that the EDC will

use the distribution facilities identified in the pre-application report to

connect to the project. The potential applicant must request additional pre-application

reports if information about multiple points of interconnection is requested.

Subject to subsection (c), the pre-application report shall include the

following information:

1)         Identification of up to two distribution

circuits within one quarter mile of the proposed point of interconnection,

including the following information:

A)        Substation

and circuit identifying information;

B)        Feeder

configuration (e.g., radial or network);

C)        Number

and size of phase conductors at the point of interconnection;

D)        Distance

to three-phase (if applicable);

E)        Primary

circuit voltage at the point of interconnection;

F)         Existing

aggregate generation capacity interconnected to the identified substations and circuits;

G)        Aggregate

generation capacity and non-binding estimated costs associated with projects

earlier in the queue and planned for the identified substations and circuits;

H)        Capacity

of the substation transformer, sub

Primary

circuit voltage at the point of interconnection;

F)         Existing

aggregate generation capacity interconnected to the identified substations and circuits;

G)        Aggregate

generation capacity and non-binding estimated costs associated with projects

earlier in the queue and planned for the identified substations and circuits;

H)        Capacity

of the substation transformer, substation circuit equipment, and lowest rated

circuit equipment between the proposed point of interconnection and the

substation/area bus identified;

I)         Circuit

peak and minimum load: estimated if actual is unavailable (i.e., minimum load

from 10 a.m. to 4 p.m. Central Prevailing Time for fixed panel photovoltaic

(PV) systems, from 8 a.m. to 6 p.m. for PV systems using tracking systems, or

absolute minimum for non-PV and energy storage systems);

J)         Approximate

circuit distance between the proposed point of interconnection and the

identified substation or area bus;

K)        Size

and type of relevant protective devices between the proposed point of

interconnection and the substation/area bus identified, including:

i)          Lowest rated upstream

recloser, where applicable; and

ii)         Lowest

rated upstream fuse, where applicable;

L)        Number

of regulating devices between the proposed point of interconnection and the

substation/area bus identified; and

M)       For the

EDC's proposed point of interconnection, all existing or anticipated

constraints that might affect the interconnection.

2)         Disclosure

from the EDC as to whether the aggregate contingent upgrades of the systems

earlier in the queue are estimated to exceed the following thresholds, if such

estimates are available:

A)        Distribution

facility replacement/upgrades of $50,000;

B)        Substation

transformer replacement/upgrades of $100,000; or

C)        Transmission

replacement/upgrades of $100,000.

c)         The

pre-application report need only include existing data

gent upgrades of the systems

earlier in the queue are estimated to exceed the following thresholds, if such

estimates are available:

A)        Distribution

facility replacement/upgrades of $50,000;

B)        Substation

transformer replacement/upgrades of $100,000; or

C)        Transmission

replacement/upgrades of $100,000.

c)         The

pre-application report need only include existing data. A pre-application

report request does not obligate the EDC to conduct a study or other analysis

of the proposed generator in the event that data is not available.  The

information concerning "available capacity" provided within the

pre-application report represents the best information available to the EDC at

the time of reporting and does not imply that an interconnection up to this

level may be completed without impacts.
