ComEd Bills Drop About $19 in April Under Illinois Nuclear Credit Program

Overview

• ComEd says the average residential customer will see about $19.40 credited on April bills, with the exact amount tied to usage.
• The credit flows from the 2021 Climate and Equitable Jobs Act, which created Carbon Mitigation Credits with a cap that returns revenue above a set threshold to customers.
• An $803 million federal tax credit to Constellation and higher PJM market and capacity prices have boosted refunds, including $404 million in January and more than $580 million over the first two months of 2026.
• The Illinois Power Agency reports the program has delivered a net benefit greater than $1.8 billion since 2022, saving the average ComEd household about $177 to date.
• Credits post automatically as a Carbon-Free Energy Resource Adjustment on most ComEd bills and are slated to continue during high-price periods through May 2027.
