The Federal Energy Regulatory Commission on June 26 largely accepted, subject to additional changes, filings submitted by the Midcontinent ISO and the Southwest Power Pool in compliance with Order 2023, which requires all transmission owners to adopt interconnection queue reforms.
FERC also affirmed its earlier decision approving MISO and SPP’s Joint Targeted Interconnection Queue.
Both MISO and SPP were among the first to implement, years ago, the cluster approach that Order 2023 required all transmission owners to implement.
Although MISO and SPP required fewer changes to their existing practices to comply with Order 2023, they sought certain deviations from Order 2023’s requirements.
FERC allowed some of their requested deviations but declined or directed modifications to others.
FERC also issued an order on rehearing of its November 2024 orders that approved MISO and SPP’s JTIQ, which facilitates transmission upgrades at the MISO-SPP seam that will allow new generator interconnections in the area.
A group of clean energy associations sought rehearing because the November 2024 order allocated costs directly to interconnection customers; Arkansas and Mississippi sought rehearing arguing that MISO South would not benefit from the JTIQ upgrades.
FERC denied all the rehearing requests.
