Passage Likelihood

SB 3104 passed Senate Energy Committee 9-4 and is on the Senate floor calendar. Multiple companion bills in both chambers. Strong advocacy coalition. Utility opposition (ComEd) is the main risk. Illinois meets year-round so no session deadline pressure.

Expected Timeline
Senate floor vote expected April–May 2026. If passed, moves to House. Governor Pritzker (D) has been supportive of clean energy legislation.
Exempts certified plug-in solar devices from utility interconnection requirements. Prohibits utilities from charging extra fees. Allows self-installation without permits.
If passed: self-install certified systems without ComEd or Ameren approval.
Law not yet enacted. Illinois utilities currently require interconnection agreements for any grid-tied system.
Illinois Shines (SREC program) provides incentive payments for solar generation through Approved Vendors. Illinois property tax exemption excludes solar system value from property tax. ComEd offers distributed generation rebates at $300/kW (note: SB 3104 explicitly states plug-in solar does not qualify for DG rebates). The federal 30% ITC (Section 25D) expired December 31, 2025.

Illinois has a fully deregulated electricity market. You may be able to get plug-in solar bundled with your electricity plan through a Retail Energy Provider (REP) — potentially at lower cost than buying hardware outright.
