Illinois home electrification rebates (2026)
Illinois Shines is one of the best solar SREC programs left. HEAR is launching. ComEd and Ameren run real efficiency rebates. Underrated electrification state.
DOE-approved plan; pilot launch expected mid-2026.
Illinois is quietly one of the better electrification states
Illinois doesn't get the press of California or New York on electrification, but the policy fundamentals are quietly excellent:
- HEAR plan is DOE-approved and launching in 2026, with pilot programs already running in select counties.
- The state's 2021 Climate and Equitable Jobs Act (CEJA) put real money behind electrification programs administered by the Illinois Commerce Commission and Department of Commerce.
- ComEd and Ameren both run actively-funded efficiency programs with significant heat pump and HPWH rebates.
- Illinois Shines, the state's SREC program, is one of the most generous still operating in the country.
Illinois Shines: the solar program that's still mostly intact
While most states' solar incentives have shrunk or expired, Illinois Shines remains substantial. The structure:
- You install solar and the system generates SRECs (Solar Renewable Energy Certificates) — one per megawatt-hour produced.
- You enter a 15-year contract with an approved buyer through the Illinois Power Agency.
- Contract values fluctuate by block (the program is in declining blocks as capacity fills), but a typical 7 kW system in a strong block earns total SREC payments of $5,000–$10,000 over 15 years.
- For income-eligible households (Illinois Solar for All), the SREC payments are larger and there's additional upfront support.
Combine Illinois Shines with full retail net metering (still in place statewide) and you've got the closest thing to the old federal credit that any state currently offers — just structured as a 15-year revenue stream rather than a one-time credit.
Active programs in Illinois
We're tracking 3 state-level programs. Stack them with federal HEAR (where open) and utility-level rebates for the largest combined incentive.

Illinois Shines (SREC program)
Sell renewable energy certificates from your solar system on a 15-year contract.
15-year SREC contract; typical value $5,000–$10,000 over contract life
Air-Source Heat Pump
ComEd Heat Pump Rebate
Available to ComEd residential customers in northern Illinois.
$300–$1,200 depending on equipment efficiency tier
Heat Pump Water Heater
ComEd HPWH Rebate
Available to ComEd residential customers.
$400–$700 flat rebate for ENERGY STAR HPWH
The utility rebate detail
- ComEd — northern Illinois including Chicago. Heat pump rebates of $300–$1,500 depending on equipment tier. HPWH rebates $400–$900. EV charger rebates and managed-charging program rebates.
- Ameren Illinois — central and southern Illinois. Similar magnitudes to ComEd, sometimes higher for whole-home conversions.
- Municipal utilities — Springfield CWLP, Naperville, Batavia, and other muni utilities run their own programs of varying generosity.
One Illinois-specific note: ComEd's Hourly Pricing program lets residential customers pay wholesale electricity prices in real time. For households with significant flexible load (heat pumps, EVs), this can cut effective electric rates by 25–40% — far more than any rebate. Worth investigating.
A worked Chicago-area example
2,000 sq ft house in Evanston. Family of 4, household income $140,000 (~126% AMI). Replacing gas furnace + AC with heat pump and adding a HPWH:
- HEAR (pilot, if launched in their county): 50% of cost capped at $8,000 + $1,750 = $9,750 max
- ComEd heat pump rebate: ~$1,200
- ComEd HPWH rebate: ~$700
- Total stack: ~$11,650 on $20,000 of combined heat pump + HPWH install.
For the same household if HEAR is not yet open in their county: stack drops to ~$1,900. The HEAR launch timeline matters a lot here.
By product
Heat pump rebates in Illinois
Replaces your furnace and AC with a single electric system that's typically 3–4× more efficient than gas heat. The single biggest electrification upgrade most homes can make.
HPWH rebates in Illinois
Uses 60–70% less electricity than a standard electric water heater by pulling heat from surrounding air. Pays back faster than almost any other electrification upgrade.
EV rebates in Illinois
Federal EV tax credits expired Dec 31, 2025. State EV incentives, utility charger rebates, and reduced-rate charging plans are still active in many states.
Solar rebates in Illinois
Federal residential clean energy credit (25D) expired Dec 31, 2025. State solar tax credits, SREC markets, net metering, and property/sales tax exemptions remain — varying widely by state.
Induction rebates in Illinois
Faster than gas, safer for indoor air quality, and the lowest-friction electrification swap. Eligible for HEAR rebates up to $840 for income-qualified households.
Weatherization rebates in Illinois
Air sealing, attic insulation, and duct sealing. Quietly the highest-ROI energy upgrade — and a HEAR-eligible category for up to $1,600 in rebates.
Frequently asked
Is Illinois Shines fully open? +
Yes, but in blocks. The program operates in declining-incentive blocks — earlier blocks paid more per SREC than current blocks. Capacity does fill up; check program block status on the Illinois Power Agency portal before sizing your system. The Solar for All track (income-qualified) typically has dedicated capacity.
How does ComEd Hourly Pricing actually work? +
You opt in via ComEd's portal. Your electricity supply rate then follows the PJM wholesale market in real time, posted day-ahead and adjusted hourly. For most hours of most days, you're paying significantly less than the standard fixed rate. Spikes happen (rare summer afternoons) but with smart thermostats and load management, total bills typically come down 20–30%.
Are there state EV rebates in Illinois? +
Yes — Illinois has had a $4,000 EV rebate program through the Climate and Equitable Jobs Act. Funding has fluctuated; check current availability on the Illinois EPA Driving a Cleaner Illinois site. As of mid-2026 funding has periodically paused and resumed; the program design assumes continuing rebates but actual application windows depend on appropriations.
How big are Solar for All's additional incentives? +
Solar for All targets households ≤80% AMI and provides solar at no upfront cost in many cases — the SREC payments fully cover the install plus contractor margin. It's administered through approved installers; not every Illinois solar installer participates. Worth getting quotes from both Solar for All and traditional solar paths if you qualify.
Is geothermal worth considering in Illinois? +
For larger homes (3,000+ sq ft) with available yard space, geothermal can pencil out — Illinois has fair groundwater conditions and ComEd's electric rates are reasonable. The federal geothermal credit expired with the rest of 25D, but Illinois has historically had some additional geothermal-specific incentives through state programs. Confirm current availability before specifying geothermal.
