Energy Efficiency Rebates From Electricity Suppliers and Utilities (2026 Guide)

Billions of dollars in energy efficiency rebates are available each year from utilities, state programs, and federal tax credits — and most homeowners leave them unclaimed simply because they don’t know where to look. In deregulated electricity states, the rebate landscape is split between your utility (which delivers power and often runs efficiency programs regardless of which supplier you choose) and state/federal programs that layer on top. This guide maps out what’s available, who qualifies, and how to stack incentives for maximum return.

The Two-Tier Rebate Structure in Deregulated States

In a deregulated electricity market, you have two separate parties involved in your electricity service: the utility (the wires company that delivers power to your home) and the competitive supplier (the company that sells you the electricity commodity). Rebates and efficiency programs typically come from the utility side — not your supplier — because efficiency programs are funded through regulated delivery charges. Switching suppliers doesn’t affect your access to utility rebates.

The exception: some competitive suppliers offer their own loyalty incentives or efficiency bonuses as a differentiator. These are worth asking about but represent a small minority of available rebates.

Utility Efficiency Programs by State

Texas: Texas has historically had fewer mandatory utility efficiency programs than other deregulated states, but all four major TDUs (Oncor, CenterPoint, AEP Texas, TNMP) run Energy Efficiency Programs funded by a per-kWh charge on delivery. Rebates are available for: ENERGY STAR appliances, variable-speed HVAC, smart thermostats, insulation, and weatherization. Visit each TDU’s website or use the Texas Energy Efficiency Programs directory at energysavingtexas.com.

Illinois: ComEd and Ameren Illinois run large-scale efficiency programs under the Illinois Future Energy Jobs Act (FEJA). Available rebates: smart thermostats ($50–$100), variable-speed pool pumps ($100–$200), LED lighting (direct install or rebate), HVAC upgrades ($100–$600), electric water heaters, and low-income weatherization assistance. Income-qualified customers can receive no-cost home energy upgrades through the Illinois Home Weatherization Assistance Program (IHWAP).

Pennsylvania: PECO and PPL Electric both offer Act 129 efficiency programs with rebates for smart thermostats, ENERGY STAR appliances, HVAC upgrades, LED lighting, and weatherization. PECO’s SmartEnergy programs include audits and direct-install programs for income-qualified customers at no cost.

New York: NYSERDA (New York State Energy Research and Development Authority) administers statewide programs, and Con Edison, National Grid, NYSEG, and other utilities layer on their own incentives. New York has among the most generous efficiency programs in the country. Highlights: heat pump HVAC ($2,000–$5,000 incentives via NYSERDA’s Clean Heat program), weatherization for low-income households (EmPower+), and EV charging equipment rebates.

New Jersey: New Jersey’s Clean Energy Program offers rebates through utilities for HVAC upgrades (heat pumps, efficient furnaces), water heaters, lighting, and appliances. The Comfort Partners program provides free weatherization services to income-eligible customers.

Ohio: AEP Ohio, Duke Energy Ohio, and FirstEnergy (Ohio Edison, The Illuminating Company, Toledo Edison) all run efficiency programs with appliance rebates, smart thermostat discounts, and weatherization assistance. Ohio also participates in the federal Low Income Home Energy Assistance Program (LIHEAP) for heating and cooling bill assistance.

Federal Tax Credits for Home Energy Improvements (2026)

The Inflation Reduction Act created and expanded several federal tax credits available through 2032. These stack on top of utility rebates (you claim the rebate from the utility and the tax credit from the IRS separately):

• Energy Efficient Home Improvement Credit (25C): Up to $3,200/year in tax credits for qualifying upgrades. Eligible improvements include: heat pump HVAC ($2,000 credit), heat pump water heater ($2,000 credit), insulation and weatherization ($1,200 credit), exterior windows and doors ($600 credit), electrical panel upgrades to support electrification ($600 credit). Note: $1,200 and $2,000 are separate buckets with an aggregate annual limit of $3,200.
• Residential Clean Energy Credit (25D): 30% tax credit for solar panels, solar water heaters, battery storage (3+ kWh), geothermal heat pumps, and small wind. No annual dollar cap — 30% of the full cost. A $25,000 solar + battery system generates a $7,500 credit.

Important: these are nonrefundable credits, meaning they reduce your tax liability but don’t generate a refund if the credit exceeds what you owe. Unused credits can roll forward.

How to Stack Rebates and Credits

The most valuable thing to know: federal tax credits, state rebates, and utility rebates can all be claimed on the same purchase. A homeowner installing a heat pump HVAC system might receive:

• $2,000 federal 25C tax credit
• $1,500 NYSERDA Clean Heat incentive (or comparable state program)
• $400 utility rebate from their local utility

That’s $3,900 in combined incentives on a $12,000 system — effectively a 32% discount before you consider operating cost savings.

Income-Qualified Programs: Deeper Discounts

Income-qualified households (typically at or below 80% of Area Median Income) have access to significantly deeper assistance programs:

• Weatherization Assistance Program (WAP): Federal program that provides free insulation, air sealing, window upgrades, and HVAC improvements to income-eligible homeowners and renters. Administered by states.
• LIHEAP: Direct bill assistance for heating and cooling costs.
• IRA Low-Income Bonus Credits: Households at 80% AMI or below receive a 10–20% bonus on the 25D clean energy credit; households at 150% AMI or below receive 5–10% bonus.
• State and utility direct-install programs: In New York (EmPower+), Illinois (IHWAP), and New Jersey (Comfort Partners), income-qualified customers can receive free home efficiency upgrades installed by contractors, with zero out-of-pocket cost.

How to Find and Apply for Rebates

The best starting points for rebate discovery:

• DSIRE (dsireusa.org): The Database of State Incentives for Renewables & Efficiency — the authoritative, state-by-state catalog of rebates, credits, and incentive programs. Search by state and technology.
• Your utility’s website: Navigate to “Energy Savings” or “Rebates” — most major utilities list current programs with eligibility requirements and application forms.
• EnergyStar.gov: The EPA’s energy efficiency portal lists qualifying products and links to applicable rebate programs for each state.
• Your contractor: Licensed HVAC and insulation contractors typically know which rebates apply to their work and can often submit the rebate paperwork on your behalf.

Most rebates require you to purchase qualifying equipment, keep the receipt, and submit a form (often online) within 90–180 days of purchase. Don’t wait until year-end — some programs exhaust their annual allocation mid-year.

Frequently Asked Questions

Does switching electricity suppliers affect my utility rebate eligibility?

No. Utility efficiency rebates come from your delivery utility — the wires company — not your electricity supplier. You can switch suppliers freely without affecting rebate eligibility.

Can I claim both a utility rebate and a federal tax credit on the same upgrade?

Yes. Federal tax credits and utility rebates are independent. You claim the rebate from the utility and the credit from the IRS. A utility rebate technically reduces your cost basis for calculating the credit — so your $12,000 heat pump with a $1,500 utility rebate has an $10,500 adjusted basis for the 25C credit calculation — but you can claim both.

What ENERGY STAR appliances qualify for rebates?

Qualifying appliances vary by utility, but commonly include: ENERGY STAR-rated refrigerators, dishwashers, clothes washers and dryers, heat pump water heaters, central air conditioners, heat pump HVAC systems, smart thermostats, and window AC units. Check your utility’s specific rebate catalog — not all ENERGY STAR models qualify for every program.

Do renters qualify for efficiency rebates?

Some utility rebates are available to renters for appliances they own (refrigerators, window ACs, smart thermostats). Rebates for structural improvements (insulation, windows, HVAC) typically require homeowner status or landlord authorization. Income-qualified direct-install programs (WAP, EmPower+) often serve both renters and homeowners.

How long does it take to receive a utility rebate?

Processing times vary: most utility rebate programs pay out in 4–12 weeks after submitting a complete application. Some utilities offer instant rebates at point of sale through participating retailers, eliminating the wait entirely. Federal tax credits are claimed on your annual tax return, so timing depends on when you file.
