FERC rejects ComEd's cancellation of PowerHouse Hillwood data center contract

Chairman of the Federal Energy Regulatory Commission

The Federal Energy Regulatory Commission (FERC) on September 22, 2026, rejected Commonwealth Edison's (ComEd) attempt to cancel a transmission security agreement with PowerHouse Hillwood Holding, the developer behind a 1.8-gigawatt, $20-billion data center planned for Joliet, Illinois. The agency declined to take jurisdiction over the contract dispute, saying the U.S. District Court for the Northern District of Illinois is the right venue to resolve it.
