PSEG Long Island Rebates
Administered by: PSEG Long Island Status: Active in 2026 Verified: May 27, 2026 against PSEG Long Island Home Efficiency Programs Source quality: Primary
What it is
PSEG Long Island serves Nassau County, Suffolk County, and the Rockaway Peninsula in Queens. If that is your electric utility, you have access to rebates on heat pump water heaters, smart thermostats, ground-source (geothermal) heat pumps, and a free home energy assessment. Long Island heat pump installs also coordinate with the statewide NYS Clean Heat program, which runs parallel to PSEG LI's own structure.
The rebate portal for heat pump and thermostat rebates is at psegli.capturesportal.com. The main PSEG LI site is where you look up what is currently available. A contractor finder lives at pseglinyportal.com.
PSEG Long Island is not PSE&G New Jersey, and it is not National Grid. The three utilities have overlapping names and different rebate programs. National Grid serves the gas side of Long Island; PSEG LI serves the electric side.
Who qualifies
- PSEG Long Island electric customers in Nassau County, Suffolk County, or the Rockaway Peninsula.
- Heat pump water heater: ENERGY STAR certified unit from a participating partner.
- Smart thermostat: ENERGY STAR certified model on PSEG LI's published eligible list.
- Smart Savers Thermostat Program: must have central air conditioning. Window units, ductless mini-splits, and homes with no AC do not qualify.
- Geothermal: equipment must be purchased from and installed by a participating Geothermal Partner. Specific EER and COP efficiency thresholds apply.
- Income-tier rebates: documentation of household income or qualifying address required.
What you get
Heat pump water heaters:
- Up to $1,200 for ENERGY STAR certified units from participating partners.
- An installer incentive may be available through the contractor.
Smart thermostats:
- $100 to $130 for ENERGY STAR certified models.
- Instant incentive also available through the PSEG LI Marketplace.
Smart Savers Thermostat Program:
- $85 for enrolling an eligible thermostat. Central air conditioning required.
- Demand-response program: PSEG LI can briefly adjust your thermostat during peak grid demand. Not a pure equipment rebate.
Geothermal (ground-source) heat pumps, residential space heating:
- Market rate: up to $12,000 per dwelling new; $6,000 retrofit.
- Disadvantaged Communities / Moderate Income: up to $15,000 new; $7,500 retrofit.
- Low Income: up to $24,000 new; $12,000 retrofit.
- Additional $250 rebate for a qualifying desuperheater.
- Dedicated geothermal water heating: $1,000 per 12,000 BTU/h (new, market rate); $500 retrofit. Low-income tier doubles those amounts.
Home Energy Assessment:
- Free. PSEG LI says customers save up to 20% on energy bills after completing one.
How to apply
- Heat pump water heaters and smart thermostats: submit at psegli.capturesportal.com. For Lowe's heat pump water heater purchases, the rebate may be applied as an instant discount at the register; ask before checkout.
- Geothermal: work through a participating Geothermal Partner from the PSEG LI contractor finder. The installer files the rebate; most homeowners see it applied as a price reduction on the final invoice.
- Smart Savers Thermostat Program: enroll through the program page on psegliny.com after the device is installed and connected.
- Free home energy assessment: schedule through psegliny.com/saveenergyandmoney/homeefficiency.
How this stacks with other programs
- PSEG LI geothermal + NY State Geothermal Credit: The state offers a 25% income tax credit (capped at $5,000) on ground-source systems. PSEG LI's rebate cuts your out-of-pocket cost; the state credit applies to what you paid after the rebate. The two stack cleanly.
- PSEG LI thermostat + NY-Sun: The thermostat rebate runs through PSEG LI's capture portal; NY-Sun runs through your solar installer. Long Island is eligible for NY-Sun residential incentives. Claim each separately.
- PSEG LI + Comfort Home: Comfort Home covers envelope work (insulation, air sealing). PSEG LI does not duplicate that scope. Sequence envelope first, then add heat pump or geothermal through PSEG LI. Right-sized equipment after envelope work costs less.
- Long Island and community solar: LI sits inside Long Island Power Authority territory. Some NYSERDA programs apply on LI; others fund only the upstate investor-owned-utility side. Confirm program-by-program.
- Income-qualified path: EmPower+ covers no-cost weatherization, and income certification may unlock higher PSEG LI geothermal tiers. Apply for EmPower+ first.
- State solar credit: NY State Solar Tax Credit stacks with NY-Sun on the solar side.
- Gas-side sibling: National Grid Rebates cover gas heating equipment on Long Island.
What to ask your contractor or PSEG LI Marketplace
- Are you a Clean Heat certified contractor for PSEG Long Island? For geothermal, are you a participating Geothermal Partner? Equipment installed outside the partner network is not eligible.
- Will the rebate flow through psegli.capturesportal.com, or a separate path (such as a Lowe's instant rebate at the register)?
- For a heat pump water heater: are you using Lowe's instant rebate, the capture portal mail-in rebate, or a distributor incentive? Each has its own paperwork.
- Which smart thermostat models are on PSEG LI's currently eligible list? An ENERGY STAR sticker alone is not enough.
- For Smart Savers: does my specific central AC qualify? If you do not have central AC, the program is not available.
- Can you schedule the free home energy assessment for the same site visit, or does PSEG LI dispatch a separate auditor?
Common pitfalls
- Confusing PSEG LI with PSE&G New Jersey. Same parent company, different utility. New Jersey rebates do not apply on Long Island.
- Confusing PSEG LI with National Grid. National Grid serves the gas side of Long Island; PSEG LI serves the electric side. Heat pump rebates run through PSEG LI; gas furnace and boiler rebates run through National Grid.
- Smart Savers without central AC. The program requires central air conditioning. Ductless mini-splits, window units, and no-AC homes disqualify the rebate even if the thermostat is on the eligible list.
- Missing the capture portal. Many homeowners look only at psegliny.com and miss the submission site. Heat pump water heater and thermostat applications live at psegli.capturesportal.com.
- Geothermal installer outside the partner network. The geothermal rebate requires a participating Geothermal Partner. An installer not on the list disqualifies the rebate.
- Per-dwelling caps vs. per-ton math. Older third-party trackers describe the program as $2,400 per heating ton. PSEG LI's current page publishes the cap as a per-dwelling number ($12,000 market-rate new).
Important dates
No published program-end dates as of May 27, 2026. Geothermal amounts were updated for the 2026 program year. Rebate budgets are annual; for a 2026 install, file as early in the year as equipment delivery allows.
