Illinois Hits $10B Clean Energy Milestone, Powers 306K Homes

Northern Illinois families are breathing cleaner air and saving money thanks to a massive renewable energy milestone that just changed the game for the entire region.

ComEd announced it has surpassed $10 billion in Renewable Energy Credits under contract, marking one of the largest clean energy commitments in the state's history. The investment has brought 383 million megawatt-hours of new renewable energy to northern Illinois, enough to keep the lights on in 306,000 homes for a full year.

The growth happened faster than almost anyone expected. In 2025 alone, ComEd added 105 million additional credits under contract, making it one of the most significant single-year expansions of renewable energy support Illinois has ever seen.

Rooftop solar installations have exploded across the region, reaching 1.7 gigawatts on ComEd's grid. These distributed energy resources put power generation directly in neighborhoods, reducing transmission costs and giving families more control over their energy bills.

The investment works by providing financial certainty to renewable energy developers through contracts lasting up to 20 years. This long-term commitment helps developers secure financing and build projects that bring more affordable clean energy options to customers across northern Illinois.

The Ripple Effect

This milestone reflects Illinois's bold commitment to a cleaner future. The state's Climate and Equitable Jobs Act, passed in 2021, charts a path to 100% clean energy by 2050, with ambitious checkpoints along the way: 40% renewable energy by 2030 and 50% by 2040.

The benefits extend far beyond lower electricity bills. Every megawatt of renewable energy reduces air pollution, creates local jobs in installation and maintenance, and strengthens the grid against climate-related disruptions.

Northern Illinois is proving that ambitious climate goals and economic benefits can go hand in hand. As more rooftop solar panels appear on homes and businesses, the region is building energy independence one installation at a time.

The $10 billion milestone shows what's possible when utilities, policymakers, and communities align around a shared vision for cleaner, more affordable energy that works for everyone.
