MISO (Midcontinent) Energy Storage Analysis

The Midcontinent Independent System Operator (MISO) covers a vast geographic footprint from the Canadian border to the Gulf of Mexico. The region is undergoing a massive transformation, retiring legacy coal fleets while interconnecting gigawatts of wind in the north and solar in the south. Unlike ERCOT or CAISO, the storage market in MISO is still in its early stages of regulatory formation. However, the sheer scale of the renewable build-out and the increasing frequency of extreme weather events (e.g., Winter Storm Elliott) are forcing MISO to rapidly integrate battery storage to ensure resource adequacy and manage severe north-to-south transmission congestion.
