Overview

• The capacity charge hike took effect June 1, 2025, boosting average monthly residential ComEd bills by about 10%, roughly $10.60.
• The increase stems from the 2024 PJM Interconnection capacity auction, which sets annual supply costs based on last summer’s energy usage and market bids.
• ComEd says it passes these wholesale capacity costs directly to customers with no markup and retains no proceeds from the charge.
• Illinois Attorney General Kwame Raoul has filed a complaint with FERC calling the auction rules flawed and asking for a rerun under revised guidelines.
• The Climate and Equitable Jobs Act is set to provide targeted relief for affected customers through October 2025.
