PSEG Long Island Rebates

Administered by: PSEG Long Island Status: Active in 2026 Verified: May 22, 2026 against PSEG Long Island Home Efficiency Programs

What it is

PSEG Long Island serves Nassau and Suffolk counties, plus the Rockaway Peninsula in Queens. If that's your utility, you have access to rebates on heat pump water heaters, smart thermostats, and home energy assessments. Geothermal and central heating and cooling rebates are also listed under their HomeComfort program. Long Island heat pump installs also coordinate with the statewide NYS Clean Heat program, which runs parallel to PSEG LI's own rebate structure.

The rebate portal for heat pump and thermostat rebates is at psegli.capturesportal.com. That's where you submit applications; the main PSEG LI site is where you look up what's available. PSEG Long Island also maintains a contractor finder at pseglinyportal.com if you need to find an eligible installer.

Who qualifies

• PSEG Long Island electric service customers in Nassau or Suffolk counties or the Rockaway Peninsula
• Heat pump water heater: must purchase and install an eligible ENERGY STAR certified unit from a participating partner
• Smart thermostat: ENERGY STAR certified models on the published eligible list
• Smart Savers Thermostat Program: must have central air conditioning
• Geothermal and heating/cooling rebates: specific eligibility requirements are listed on the HomeComfort program page

What you get

Heat pump water heaters:

• Up to $1,200 for ENERGY STAR certified units purchased from participating partners
• Additional installer incentive may be available through the contractor

Smart thermostats:

• $100 to $130 rebate for ENERGY STAR certified models
• Instant incentive also available through the PSEG LI Marketplace

Smart Savers Thermostat Program:

• $85 rebate for enrolling an eligible thermostat; requires central air conditioning
• This is a demand response program (PSEG LI can briefly adjust your thermostat during peak grid demand), not a pure equipment rebate

Geothermal (ground-source) heat pumps:

• Rebate available; specific dollar amount was not published on the overview page reviewed. Visit the HomeComfort page or call PSEG Long Island for the current amount.

Home Energy Assessment:

• Free; PSEG LI says customers save up to 20% on energy bills after completing one. Long Island homeowners adding solar can also access state incentives through the NY-Sun program.
