Current through Register Vol. 54, No. 38, September 21, 2024
(a) An EDC shall use the Level 2
interconnection review procedure for an interconnection request that meets the
criteria in §
75.34(2)
(relating to review procedures). An EDC may not impose additional requirements
for Level 2 reviews not specifically authorized under this
subchapter.
(b) The Level 2
screening criteria must consist of:
(1) For
interconnection of a proposed small generator facility to a radial distribution
circuit, the aggregated generation on the circuit, including the proposed small
generator facility, may not exceed 15% of the line section annual peak
load.
(2) For interconnection of a
proposed small generator facility to the load side of spot network protectors,
the proposed small generator facility shall utilize an inverter-based equipment
package. The customer interconnection equipment proposed for the small
generator facility must be certified and, when aggregated with other
generation, may not exceed 5% of a spot network's maximum load.
(3) The proposed small generator facility, in
aggregation with other generation on the distribution circuit, may not
contribute more than 10 % to the distribution circuit's maximum fault current
at the point on the primary voltage distribution line nearest the point of
common coupling.
(4) The proposed
small generator facility, in aggregate with other generation on the
distribution circuit, may not cause any distribution protective devices and
equipment (including substation breakers, fuse cutouts, and line reclosers), or
other customer equipment on the electric distribution system to be exposed to
fault currents exceeding 85% of the short circuit interrupting capability. The
interconnection request may not request interconnection on a circuit that
already exceeds 85% of the short circuit interrupting capability.
(5) The proposed small generator facility's
point of interconnection may not be on a transmission line.
(6) When a customer-generator facility is to
be connected to 3 phase, 3 wire primary EDC distribution lines, a 3 phase or
single-phase generator shall be connected phase-to-phase.
(7) When a customer-generator facility is to
be connected to 3 phase, 4 wire primary EDC distribution lines, a 3 phase or
single phase generator will be connected line-to-neutral and will be
effectively grounded.
(8) This
Level 2 screen includes a review of the type of electrical service provided to
the interconnection customer, including line configuration and the transformer
connection to limit the potential for creating over voltages on the EDC's
electric distribution system due to a loss of ground during the operating time
of any anti-islanding function.
(9)
When the proposed small generator facility is to be interconnected on
single-phase shared secondary line, the aggregate generation capacity on the
shared secondary line, including the proposed small generator facility, will
not exceed 20 kW.
(10) When a
proposed small generator facility is single-phase and is to be interconnected
on a center tap neutral of a 240 volt service, its addition may not create an
imbalance between the two sides of the 240 volt service of more than 20% of the
nameplate rating of the service transformer.
(11) A small generator facility, in aggregate
with other generation interconnected to the distribution side of a substation
transformer feeding the circuit where the small generator facility proposes to
interconnect, may not exceed 2 MW in an area where there are known or posted
transient stability limitations to generating units located in the general
electrical vicinity (for example, three or four distribution busses from the
point of interconnection).
(12)
Except as permitted by an additional review under the standard small generator
interconnection agreement, no construction of facilities by an EDC on its own
system will be required to accommodate the small generator facility.
(c) The Level 2 interconnection
procedure must consist of the following:
(1)
An EDC shall, within 10 business days after receipt of the interconnection
request, inform the applicant that the interconnection request is complete or
incomplete and what materials are missing.
(2) When an EDC determines additional
information is required to complete an evaluation, the EDC shall request the
information. The time necessary to complete the evaluation may be extended, but
only to the extent of the delay required for receipt of the additional
information. The EDC may not revert to the start of the review process or alter
the interconnection customer's queue position.
(3) When an interconnection request is
complete, the EDC shall assign a queue position. The queue position of the
interconnection request shall be used to determine the potential adverse system
impact of the small generator facility based on the relevant screening
criteria. The EDC shall schedule a scoping meeting to notify the
interconnection customer about other higher-queued interconnection customers on
the same substation bus or spot network for which interconnection is
sought.
(4) Within 20 business days
after the EDC notifies the interconnection customer it has received a completed
interconnection request, the EDC shall:
(i)
Evaluate the interconnection request using the Level 2 screening
criteria.
(ii) Review the
interconnection customer's analysis, if provided by interconnection customer,
using the same criteria.
(iii)
Provide the interconnection customer with the EDC's evaluation, including a
comparison of the results of its own analyses with those of interconnection
customer, if applicable. When an EDC does not have a record of receipt of the
interconnection request and the applicant can demonstrate that the original
interconnection request was delivered, the EDC shall expedite its review to
complete the evaluation of the interconnection request within 20 business days
of the applicant's resubmittal.
(5) Upon notice within 10 business days after
receipt of the certificate of completion, the EDC may conduct a witness test at
a mutually convenient time. If the EDC does not conduct the witness test within
10 business days or within the time otherwise mutually agreed to by the
parties, the witness test is deemed waived.
(d) When an EDC determines that the
interconnection request passes the Level 2 screening criteria, or fails one or
more of the Level 2 screening criteria but determines that the small generator
facility can be interconnected safely and reliably, it shall provide the
interconnection customer a standard small generator interconnection agreement
within 5 business days after the determination.
(e) Additional review may be appropriate when
a small generator facility has failed to meet one or more of the Level 2
screens. An EDC shall offer to perform additional review to determine whether
minor modifications to the electric distribution system would enable the
interconnection to be made consistent with safety, reliability and power
quality criteria. The EDC shall provide the applicant with a nonbinding, good
faith estimate of the costs of additional review and minor modifications. The
EDC shall undertake the additional review or modifications only after the
applicant consents to pay for the review and modifications.
(f) An interconnection customer shall have 30
business days or another mutually agreeable time frame after receipt of the
standard small generator interconnection agreement to sign and return the
agreement. When an interconnection customer does not sign the agreement within
30 business days, the interconnection request will be deemed withdrawn unless
the interconnection customer requests to have the deadline extended. The
request for extension may not be unreasonably denied by the EDC. When
construction is required, the interconnection of the small generator facility
will proceed according to any milestones agreed to by the parties in the
standard small generator interconnection agreement. The interconnection
agreement may not become final until:
(1) The
milestones agreed to in the standard small generator interconnection agreement
are satisfied.
(2) The small
generator facility is approved by electric code officials with jurisdiction
over the interconnection.
(3) The
interconnection customer provides a certificate of completion to the EDC.
Completion of local inspections may be designated on inspection forms used by
local inspecting authorities.
(4)
There is a successful completion of the witness test, unless waived.
(g) If the small generator
facility is not approved under a Level 2 review, the interconnection customer
may submit a new interconnection request for consideration under a Level 3 or
Level 4 interconnection review; however, the queue position assigned to the
Level 2 interconnection request shall be retained.
