Section 466.70  Lab-Certified Equipment

An interconnection request may be eligible for expedited

interconnection review under Section 466.90 if the distributed energy resources

facility uses interconnection equipment that is lab-certified.  Interconnection

equipment shall be deemed to be lab-certified upon establishment of the

following:

a)         The

interconnection equipment has been successfully tested in accordance with IEEE

Standard 1547.1, and it complies with the appropriate codes and standards

referenced in subsection (f) as demonstrated by any NRTL recognized by OSHA to

test and certify interconnection equipment; and

b)         The

interconnection equipment has been labeled and is publicly listed by the NRTL

at the time of the interconnection request; and

c)         The

NRTL testing the interconnection equipment makes all test standards and

procedures that it used to perform equipment certification available, and, with

applicant approval, the test data itself.  The NRTL may make this information

readily available by publishing it on its web site and by encouraging it to be

included in the manufacturer's literature accompanying the equipment; and

d)         The

applicant's use of the interconnection equipment falls within the use or uses

for which the interconnection equipment was labeled and listed by the NRTL; and

e)         The

generator, other electric sources, and interface components being utilized are

compatible with the interconnection equipment and are consistent with the

testing and listing specified by the NRTL for this type of interconnection

equipment; and

f)         To

meet the requirements for lab certification, interconnection equipment shall be

evaluated by an NRTL in accordance with the following codes and standards:

1)         IEEE

1547 Standard for Interconnecting Distributed Resources with Electric Power

Systems (including use of IEEE 1547.1 testing protocols to establish

conformity);

2)         UL

1741 Inverters, Converters, Controllers and Interconnection

e requirements for lab certification, interconnection equipment shall be

evaluated by an NRTL in accordance with the following codes and standards:

1)         IEEE

1547 Standard for Interconnecting Distributed Resources with Electric Power

Systems (including use of IEEE 1547.1 testing protocols to establish

conformity);

2)         UL

1741 Inverters, Converters, Controllers and Interconnection System Equipment

for Use With Distributed Energy Resources; and

3)         NFPA

Batterymarch Park, Quincy MA 02169-7471.  This incorporation does not include

any later amendments or editions; and

g)         Lab-certified

interconnection equipment shall not require further design testing or production

testing, as specified by IEEE Standard 1547 Sections 5.1 and 5.2, or additional

interconnection equipment modification to meet the requirements for expedited

review; however, nothing in this Section shall preclude the need for an

interconnection installation evaluation, commissioning tests or periodic

testing as specified by IEEE Standard 1547 Sections 5.3, 5.4 and 5.5 or for a

witness test conducted by an EDC.
