ComEd Renewable Energy Investments Help Expand Customer Access to Clean Energy and Lower Costs
$10 billion in renewable energy credits expands access to wind and solar, supports customer savings and reduces emissions across Illinois
ComEd today announced it exceeded $10 billion in Renewable Energy Credits (RECs) under contract at the end of 2025 – an investment that is helping expand access to clean energy, support lower energy costs over time, and deliver environmental benefits for customers across Illinois. The milestone is equivalent to 383 million megawatt-hours of new renewable energy produced in Illinois. Distributed energy resources (DER) like rooftop solar have reached 1.7 gigawatts (GW) on ComEd’s grid, which is enough to power 306,000 homes for a year.
Growth accelerated in 2025 with approximately 105 million additional RECs added under contract last year, making it one of the most significant single-year expansions of renewable energy support in Illinois history. RECs represent the environmental attributes of electricity generated from renewable energy. The $10 billion milestone reflects the cumulative value of ComEd’s active REC contracts, which it pays out to renewable energy developers over terms of up to 20 years. These long-term commitments provide financial certainty for developers while helping bring more affordable renewable energy options to customers across Illinois.
