MISO's plan to speed 71 GW legacy interconnection queue draws state and developer support at FERC
MISO's proposal to accelerate its remaining Definitive Planning Phase-2022 study cycle, which includes about 71 GW of projects, drew support in Oct. 5, 2026 filings at FERC from the Organization of MISO States, RWE Americas, Ameren and Alliant Energy. MISO says that without changes the cycle will likely be delayed by at least 18 months. It asked FERC to approve the plan by Oct. 19, ahead of the Oct. 20 Decision Point II. Pathway Power protested, saying the higher cost-increase threshold shifts financial risk to projects remaining in the queue.
Faster resolution of MISO's legacy queue could shorten and firm up timelines for generation that data center builders and AI strategy leads depend on in the Midcontinent region, though the proposal remains pending at FERC.
