Section 20:10:36:32 - Tier 1 interconnection evaluation and screening criteria

A tier 1 interconnection shall use the following evaluation and screening criteria:

(1) For interconnection of a proposed small generator facility to a radial distribution circuit, the aggregated generation must not exceed 15 percent of the line section annual peak load as most recently measured at the sub-station or calculated for the line section. Aggregated generation includes the proposed small generator facility, FERC wholesale generators, and FERC wholesale generators with a higher queue position;

(2) For interconnection of a proposed small generator facility to the load side of spot network protectors, the proposed small generator facility and the aggregated other generation and applications with a higher queue position must not exceed the lesser of 5 percent of a spot network's maximum load or 50 kilowatts;

(3) If the proposed small generator facility is to be interconnected on a single-phase shared secondary service line, the aggregated generation capacity on the shared secondary, which includes the proposed small generator facility and applications with a higher queue position, must not exceed 20 kilowatts; and

(4) If the proposed small generator facility is single-phase and is to be interconnected on a center tap neutral of a 240 volt service line, its addition must not create a current imbalance between the two sides of the 240 volt service of more than 20 percent of the nameplate rating of the service transformer.

The proposed interconnection must use existing public utility facilities.
