An EDC shall determine whether an interconnection request should be processed under the Level 1, 2, 3 or 4 procedures by using the following screens:
a)Â Â Â Â Â Â Â Â An EDC shall use Level 1 procedures to evaluate all interconnection requests to connect a distributed generation facility when:
1)Â Â Â Â Â Â Â Â The applicant has filed a Level 1 application; and
2)Â Â Â Â Â Â Â Â The distributed generation facility has a nameplate capacity of 25 kW or less; and
3)Â Â Â Â Â Â Â Â The distributed generation facility is inverter-based; and
4)Â Â Â Â Â Â Â Â The customer interconnection equipment proposed for the distributed generation facility is lab-certified.
b)Â Â Â Â Â Â Â Â An EDC shall use Level 2 procedures for evaluating interconnection requests when:
1)Â Â Â Â Â Â Â Â The applicant has filed a Level 2 application;
2)Â Â Â Â Â Â Â Â For certified inverter-based systems, the size limit varies according to the voltage of the line at the proposed point of interconnection:
Line Voltage | Level 2 Eligibility |
< 5 kV | ≤ 500 kW |
≥ 5 kV and < 15 kV | ≤ 3 MW |
≥ 15 kV and < 30 kV | ≤ 4 MW |
≥ 30 kV and ≤ 69 kV | ≤ 5 MW |
3)        All distributed generation facilities connecting to lines greater than 69 kV are ineligible for Level 2 review regardless of size. All synchronous and induction machines must be no larger than 2 MW to be eligible;
4)Â Â Â Â Â Â Â Â The interconnection equipment proposed for the distributed generation facility is lab-certified; and
5)Â Â Â Â Â Â Â Â The proposed interconnection is to a radial distribution circuit or a spot network limited to serving one customer.
c)Â Â Â Â Â Â Â Â An EDC shall use Level 3 review procedures for evaluating interconnection requests to area networks and radial distribution circuits where power will not be exported based on the following criteria.
1)Â Â Â Â Â Â Â Â For interconnection requests to the load side of an area network, the following criteria shall be satisfied to qualify for a Level 3 expedited review:
A)Â Â Â Â Â Â Â The applicant has filed a Level 3 application; and
B)Â Â Â Â Â Â Â The nameplate capacity of the distributed generation facility is less than or equal to 50 kW; and
C)Â Â Â Â Â Â Â The proposed distributed generation facility uses a lab-certified inverter-based equipment package; and
D)Â Â Â Â Â Â Â The distributed generation facility uses reverse power relays and/or other protection functions that prevent the export of power into the area network; and
E)Â Â Â Â Â Â Â The aggregate of all generation on the area network does not exceed the lower of 5% of an area network's maximum load or 50 kilovolt amperes (kVA).
2)Â Â Â Â Â Â Â Â For interconnection requests to a radial distribution circuit, the following criteria shall be satisfied to qualify for a Level 3 expedited review:
A)Â Â Â Â Â Â Â The applicant has filed a Level 3 application; and
B)Â Â Â Â Â Â Â The aggregated total of the nameplate capacity of all of the generators on the circuit, including the proposed distributed generation facility, is 10 MVA or less; and
C)Â Â Â Â Â Â Â The distributed generation facility will use reverse power relays or other protection functions that prevent power flow onto the electric distribution system; and
D)Â Â Â Â Â Â Â The distributed generation facility is not served by a shared transformer.
d)Â Â Â Â Â Â Â Â An EDC shall use the Level 4 study review procedures for evaluating interconnection requests when:
1)Â Â Â Â Â Â Â Â The applicant has filed a Level 4 application; and
2)Â Â Â Â Â Â Â Â The nameplate capacity of the small generation facility is 10 MVA or less; and
3)Â Â Â Â Â Â Â Â Not all of the interconnection equipment or distributed generation facilities being used for the application is lab-certified.
