ComEd Tops $10B in Renewable Energy Credits, Accelerates Illinois Clean Energy Transition
Event summary
- ComEd exceeded $10 billion in Renewable Energy Credits (RECs) under contract by the end of 2025, equivalent to 383 million megawatt-hours of new renewable energy produced in Illinois.
- Distributed energy resources (DER) like rooftop solar reached 1.7 gigawatts (GW) on ComEd’s grid, enough to power 306,000 homes for a year.
- 2025 saw the addition of approximately 105 million RECs under contract, marking one of the most significant single-year expansions of renewable energy support in Illinois history.
- ComEd’s Grid Plan, submitted to the ICC in January 2026, aims to support the clean energy transition by enabling additional residential and commercial solar projects, battery storage, and other emerging technologies.
The big picture
ComEd’s $10 billion REC milestone underscores the scale of Illinois’ clean energy policies and the critical role of RECs in financing renewable projects. The state’s ambitious targets under CEJA—40% renewable energy by 2030 and 100% clean energy by 2050—are driving significant investments in distributed energy resources and grid modernization. ComEd’s strategic focus on long-term REC contracts and grid upgrades positions it as a key player in the transition to a multi-directional, renewable-powered grid.
