Key Issues

—
New multi-year integrated grid plans in ICC proceedings — ComEd (Docket P2026-0047) and Ameren Illinois (Docket P2026-0051) each filed 2028-2031 grid plans with the ICC on January 20, 2026, the statutory deadline under CEJA. The prior cycle ended badly: ICC rejected both utilities' initial plans before approving slimmer versions, triggering Moody's and Morgan Stanley downgrades on Exelon and Ameren. ICC proceedings on the new plans will determine investment levels and rate trajectory through 2031.
—
Clean and Reliable Grid Affordability Act (CRGA) takes effect June 1, 2026 — Signed by Governor Pritzker in October 2025, CRGA significantly amends CEJA. Replaces cumulative persistent annual savings targets with a 2% annual savings goal (ComEd starts 2027, Ameren ramps to 2% by 2029). Illinois Power Agency conducting initial battery storage procurement of ~1,000 MW (4-hour) by end of August 2026. First state Integrated Resource Plan (IRP) due November 15, 2026.
—
Affordability tension as rates rise — ComEd residential bills up ~$3.10/month in 2026; Ameren ~$0.39/month. ICC shaved $25.4M from ComEd's request and $11.2M from Ameren's, but cumulative increases under CEJA grid modernization remain a flashpoint for the Citizens Utility Board and low-income advocates. ICC Post-Workshop Low-Income Discount report due April 24, 2026; Ameren Illinois low-income discounts begin June 1, 2026.
—
Energy efficiency program transition — ComEd (Docket 25-0213) and Ameren Illinois (Docket 25-0211) filed 2026-2029 EE and Demand Response Plans. CRGA shifts the framework from CEJA's cumulative targets to annual percentage goals, with ComEd reaching 2% by 2027 and Ameren ramping through 2029.
—
Nuclear fleet as clean energy backbone — Illinois hosts the largest nuclear fleet in the US (Constellation operates Braidwood, Byron, Dresden, LaSalle, Quad Cities). CEJA extended nuclear support payments; reliability of this baseload is foundational to Illinois' clean energy math. Any material change in plant economics or capacity market outcomes is a first-order issue for IL grid planning.
