20:10:36:43. Tier 3 interconnection screening criteria. A
tier 3 small generator facility meeting all tier 3 evaluation and screening
criteria shall be further evaluated using tier 2 evaluation and screening
criteria, except that the 15 percent tier 2 screen does not apply to tier 3
small generator facilities.
Tier 3 interconnections do not require an interconnection
feasibility study. However, the public utility may choose to conduct such a
study at its own expense, and it must complete the interconnection feasibility
study within 25 calendar days.
For a small generator facility to interconnect to the load
side of an area network distribution circuit, the following criteria must be
met:
(1) The electric nameplate capacity of the small
generator facility is 50 kilowatts or less;
(2) The proposed small generator facility
utilizes a lab tested, inverter-based equipment package for interconnection;
(3) The small generator facility utilizes low
forward power relays or other protection functions that prevent power flow onto
the area network;
(4) The aggregated other generation on the area
network, including FERC wholesale generators and FERC wholesale generators with
a higher queue position, does not exceed the lesser of 5 percent of an area
network's maximum load or 50 kilowatts; and
(5) The interconnection uses only existing
public utility facilities and the applicant's proposed facilities.
