Stakeholders are split on whether FERC should adopt additional changes to its generator interconnection rules, or focus on implementing Order 2023 while letting specific regions go further on their own, according to comments filed after a September technical conference.

FERC approved SPP’s waiver request to delay processing its 2024 generator interconnection study cluster as the RTO works to clear a backlog of GI requests dating back to 2018.

SPP says it is devoting significant resources to finally resolve Attachment Z2, a bone of contention among SPP stakeholders since 2016 -- by the end of this decade.

MISO announced it will move forward on annual interconnection queue cap based on 50% of peak load for the year in question, this time removing exemptions for projects that regulators deem essential.

MISO and its transmission owners defended their practice of allowing TOs to self-fund network upgrades necessary to bring generation online before developers get the chance to finance them.

Speeding up the interconnection queues is becoming more important as demand growth and the retirement of existing generators combine to cut into reserve margins around the U.S., experts said during a webinar hosted by Advanced Energy United.

MISO is adamant that it should limit project proposals in future queue cycles to 50% of annual peak load to moderate its 300-GW, oversaturated queue.

FERC is considering additional changes to its rules on generator interconnections, with a technical conference set for Sept. 10-11 that saw pre-conference comments filed this week.
