The details still need to be worked out for the primary screen that addresses network interconnection.
“4. Screening Criteria for Determining Grid Impacts
Primary Screening Criteria
2. For interconnection of a proposed generator to the load side of spot network protectors, the proposed generator must utilize an inverter based equipment package and, together with the aggregated other inverter-based generation, will not exceed the smaller of 5% of a spot network’s maximum load or 50 kW [IP POSITION: AND MUST COMPLY WITH ALL REQUIREMENTS OF IEEE P1547, SECTION 4 “INTERCONNECTION TECHNICAL SPECIFICATIONS AND REQUIREMENTS”].
3. [SGC POSITION: FOR INTERCONNECTION OF GENERATORS TO THE LOAD- SIDE OF SECONDARY GRID NETWORKS, THE PROPOSED GENERATOR MUST BE AN INDUCTION GENERATOR THAT DOES NOT EXCEED 50% OF THE MINIMUM LOAD OF THE HOST FACILITY OR A GENERATOR WITH AN INVERTER-BASED EQUIPMENT PACKAGE WHICH DOES NOT EXCEED THE GREATER OF 50% OF THE MINIMUM LOAD OF THE HOST FACILITY OR 20 KW NOT EXCEEDING 30% OF PEAK LOAD.]
[IP/NARUC POSITION: THE PROPOSED GENERATOR CANNOT BE CONNECTED ON THE LOAD SIDE OF A SECONDARY NETWORK PROTECTOR, EXCEPT AS ALLOWED UNDER SECTION 4.a.2 (SPOT NETWORK) ABOVE.]”
