FERC rejects MISO interconnection cap proposal
The Federal Energy Regulatory Commission (FERC) has rejected a proposal to cap the size of the Midcontinent grid operator's interconnection queue study clusters. FERC argued the proposed exemptions to the cap could undermine its purpose and potentially impact the Midcontinent Independent System Operator's (MISO) ability to address near-term power supply shortages.
Commissioner Mark Christie likened MISO's situation to a homeowner trying to save a burning house. “MISO is trying to train the most readily available water hose on the fire as quickly as possible to save the house, an action the states in MISO support,” Christie said. “The majority acknowledges the house is on fire and that the hose MISO has chosen will likely work, but then, in classic Kafkaesque fashion, says MISO cannot use the hose. Meanwhile, the house burns.”
Grid operators across the U.S. are grappling with significant interconnection queue backlogs, and MISO's 2022 cycle exceeded peak load by about 50 gigawatts. While FERC approved other reforms proposed by MISO, it cited flaws in the cap proposal, emphasizing concerns about exemptions and their potential impact on efficiency and transparency.
