Current through Register Vol. 48, No. 12, March 22, 2024
a) At any time
after an application is deemed complete, including during the pendency of tasks
identified in Sections
466.90,
466.100,
466.110, or
466.120, the applicant
or the EDC may identify modifications to the proposed DER facility. An existing
interconnected DER facility may also propose modifications. The applicant shall
submit to the EDC, in writing, all proposed modifications to any information
provided in the interconnection request or interconnection agreement for existing
DER facilities. Neither the applicant nor the EDC may unilaterally modify the
application or interconnection agreement.
b) Within 10 business days after receipt of a
proposed modification, the EDC shall notify the applicant whether a proposed
modification to either an application or an existing DER facility constitutes a
material modification.
c) Material
Modification Process for Proposed DER
1) For
proposed generating facilities with an active interconnection request, a material
modification shall include, but is not limited to, a modification of the
interconnection request that:
A) changes the
physical location of the point of interconnection such that it is likely to affect
the scope of upgrades required to interconnect the DER;
B) increases the export capacity or extends the
operating profile of the DER facility;
C) adds or removes energy storage or changes the
energy storage operating characteristic;
D) changes or replaces generating equipment (e.g.,
generators, inverters, transformers, relaying, controls) and substitutes with
equipment that is not a like-kind modification;
E) changes transformer connections or grounding;
or
F) changes to a certified inverter
with different specifications or different inverter control settings or
configuration.
2) If the
proposed modification is determined to be a material modification, then the EDC
shall notify the applicant in writing that the applicant may elect to either:
A) withdraw the proposed modification;
or
B) withdraw the interconnection
request and proceed with a new interconnection request for the
modification.
3) The
applicant shall provide its election in writing to the EDC within 10 business days
after being provided the material modification determination results. If the
applicant does not provide its election, the proposed modification shall be deemed
withdrawn and the queue position of the withdrawn application will be forfeited. If
the applicant and EDC do not agree, either party may initiate dispute resolution
pursuant to Section
466.130.
d) A modification that is not
determined to be material may still require evaluation and acceptance by the EDC.
The applicant is obligated to pay any necessary study costs of the evaluation. The
EDC will notify the applicant of any additional fees or information that may be
required to recommence the interconnection review process and restudy the
application in order to evaluate the modification. The applicant shall have 10
business days to provide any requested information or required fees. The evaluation
will be performed within 15 business days after the EDC receives the required fees
or information from the applicant. If the proposed modification is determined not to
be a material modification, then the EDC shall conduct the technical review within
the remaining time allotted by subsection (b) and an additional 10 business days if
needed by the EDC. The EDC shall notify the applicant in writing that the
modification has been accepted, and that the applicant shall retain its eligibility
for interconnection and maintain its position in the interconnection queue. A
modification that is not determined to be material does not require a new
interconnection request.
e) Material
Modification Process for Existing Interconnected DER
1) For existing interconnected DER facilities with
an active interconnection request and have received a certificate of completion, a
material modification shall include, but is not limited to, a modification of the
interconnection request that:
A) changes the
physical location of the point of interconnection in a manner likely to have an
impact on technical review;
B) changes
the net power flow injection to the feeder, changes the nameplate capacity, or
changes the operating characteristics of the DER facility;
C) adds or removes energy storage or changes the
energy storage operating characteristics;
D) changes or replaces generating equipment (e.g.,
generators, inverters, transformers, relaying, controls), and substitutes equipment
that is not a like-kind modification;
E)
changes transformer connections or grounding; and/or
F) changes to a certified inverter with different
specifications or different inverter control settings or configuration.
2) The EDC shall notify the applicant
in writing that the applicant may elect to either:
A) withdraw the proposed modification;
or
B) submit a new interconnection
request for modification.
3)
The applicant shall provide its election in writing to the EDC within 10 business
days after being provided the material modification determination results. If the
applicant does not provide its election, the proposed modification shall be deemed
withdrawn and the modification to the existing interconnected DER facility shall not
be allowed. If the applicant and EDC do not agree, either party may initiate dispute
resolution pursuant to Section 466.130.
4) A modification that is not determined to be
material may still require evaluation and acceptance by the EDC, which includes but
is not limited to witness testing and setting verifications. The interconnection
customer is obligated to pay any applicable fees associated with the EDC's
evaluation of the proposed modification. The EDC will notify the interconnection
customer of any additional fees and/or information that may be required to evaluate
the proposed modification within five business days of providing the material
modification determination results. The interconnection customer shall have 10
business days to provide any requested information and/or required fees. If the
proposed modification is determined not to be a material modification, then the EDC
shall notify the interconnection customer in writing within 10 business days that
the modification has been accepted, contingent upon witness testing, where
applicable.
