Republicans Are Furious About Illinois’s New Energy Law – Here’s the $8 Billion Fight

Pritzker Touts $13 Billion in Savings

Governor JB Pritzker signed the Clean and Reliable Grid Affordability Act on January 8, 2026, at Joliet Junior College. The 1,020-page law is the biggest energy policy change in Illinois since 2021.

Pritzker called it a historic step to lower utility bills and secure the state’s energy future. But Republicans immediately pushed back, warning families will pay billions more for electricity under the new rules.

GOP Says Ratepayers Foot the Bill

Senator Dave Syverson said Illinois electric bills already increased nearly 40% over the last five years, and this bill adds another $8 billion in costs that will be passed directly to consumers.

House Minority Leader Tony McCombie called the legislation misleading, saying it expands mandates and bureaucracy while offering no guaranteed near-term relief for families struggling with some of the highest utility costs in the Midwest.

Democrats Project Massive Savings

The Illinois Power Agency found that the law will save utility customers in the state $13. billion over the next two decades.

Supporters argue that investing in battery storage now will suppress future capacity prices and cut monthly bills.

By 2031, the batteries could reduce average Ameren residential bills by $3.90 to $8.28 per month and ComEd bills by $1.46 to $1.85 per month.

Your Bill Gets a New Line Item

Ratepayers will not pay for battery storage until the projects are online and running, which means customers will pay less for that storage when energy and capacity prices are high.

The cost of deploying 3 gigawatts of batteries by 2031 would add 58 to 68 cents per month for Ameren customers and 40 to 48 cents for ComEd customers. The new charges start in 2030.

Bills Already Spiked This Year

A congressional report projected that Illinoisans could pay up to $200 more for electricity in 2025 compared to last year, an increase of more than 15%.

Ameren Illinois customers saw a jump from 8 cents per kilowatt-hour up to 12 cents starting in June, translating to an 18-22% total bill increase.

Families across the state have complained of triple-digit increases on summer bills.

Data Centers Are Driving Prices Up

The Independent Market Monitor for PJM showed that 70% of this year’s increase in electricity costs was the result of data center demand.

In the PJM power market stretching from Illinois to North Carolina, the extra demand from new data centers added $9.3 billion to capacity costs for 2025 and 2026.

Chicago is one of the nation’s biggest data center markets.

Homeowners Can Sell Power Back

The law creates virtual power plant programs that allow homes and businesses with solar panels or wind turbines to pool energy together, acting virtually like a power plant.

The idea is that energy stored in residential batteries can be contributed to the grid when utilities face high supply prices during peak hours, and homes that contribute will be paid for their energy.

Illinois Ends Its 1987 Nuclear Ban

Since 1987, Illinois maintained a ban on the construction of new nuclear plants.

The law officially ends the state’s nuclear moratorium, representing a reversal for Pritzker, who in 2023 vetoed a bill to lift the ban.

Illinois already generates more than half its electricity from nuclear power and has the largest fleet of nuclear reactors in the nation.

Regulators Get Long-Term Planning Power

The law grants new authority to the Illinois Commerce Commission to set long-term plans for managing energy supply and demand through approval of an integrated resource plan.

Critics say this gives too much authority to the executive branch.

Senator Sue Rezin called it a huge overreach, saying the governor gave all power for energy decisions to five unelected officials he appoints.

Blackouts Loom Without New Power

A study by three state agencies warns electricity shortages are coming to Illinois, starting in PJM’s regional transmission system by 2029 and hitting ComEd territory beginning in 2030.

Capacity shortages in downstate Ameren territory are expected to begin in 2031 and escalate through 2035. Data center demand and retiring coal plants are driving the crunch.

Union Labor Wins Major Protections

The law expands the requirement for project developers to enter into Project Labor Agreements for solar project construction.

Previously, Illinois mandated these agreements only for utility-scale renewables, but the law now covers community solar projects over 3 megawatts, energy storage projects, and geothermal projects 142 tons or larger.

Organized labor groups pushed hard for the change.

What Happens Starting June 2026

CRGA will take effect June 1, 2026. Battery storage charges hit bills in 2030.

The Illinois Power Agency says savings should fully offset costs by 2029, but Republicans remain skeptical.

The GOP has filed legislation to repeal the state’s shutdown dates for coal and gas plants and create a task force to study how recent energy laws have impacted prices and grid reliability.
