For a small generator facility to interconnect to a distribution circuit that is not networked, the following criteria shall be met for a tier 3 interconnection:

1. (1) The small generator facility has an electric nameplate capacity of 10 megawatts or less;
2. (2) The aggregated total of the electric nameplate capacity of all of the generators on the circuit, including existing FERC wholesale generators, FERC wholesale generators with a higher queue position, and the proposed small generator facility, is 10 megawatts or less;
3. (3) The small generator facility does not export power beyond the point of interconnection and employs reverse power relays or other protection functions that prevent power flow onto the EDS;
4. (4) The small generator facility's proposed interconnection is to a radial distribution circuit;
5. (5) The small generator facility is not served by a shared transformer;
6. (6) The interconnection will use only existing public utility facilities and the applicant's proposed facilities; and
7. (7) If the public utility's distribution circuit utilizes high speed reclosing with less than 2 seconds of interruption, the proposed generator may not be a synchronous machine.
