NHSaves is New Hampshire's unified energy efficiency program, jointly administered by all four NH electric utilities. This guide covers every program available to NH homeowners in 2026 -- from assessments and insulation to HPWH rebates and income-eligible benefits.
Updated February 2026
NHSaves is not a utility company or a government agency. It is the unified brand name for New Hampshire's ratepayer-funded energy efficiency programs -- a statewide initiative that helps homeowners reduce energy costs through assessments, rebates, and weatherization services. Think of it as New Hampshire's version of Mass Save in Massachusetts or Energize CT in Connecticut.
What makes NHSaves unique is its structure: all four NH electric utilities jointly administer the program under one brand. Whether you are an Eversource NH customer in Manchester, a Liberty Utilities customer in Salem, a Unitil customer on the Seacoast, or an NHEC member in the Lakes Region, you access the same programs with the same rebate amounts through NHSaves.
Funding comes from a system benefits charge on every NH electric bill. This means every NH electric customer is already paying into the program. If you pay an NH electric bill, you are eligible for NHSaves services. The program is overseen by the NH Public Utilities Commission (NH PUC).
Every program available to NH homeowners in 2026. Click any card for the full deep-dive guide with step-by-step instructions, eligibility details, and cost breakdowns.
Comprehensive 4-6 hour home energy audit. Blower door test, thermal imaging, and free installations during the visit.
Attic, wall, basement, and air sealing. 75% off for all customers (up to $8,000). 100% off for income-eligible households.
Home Performance Direct: free assessment, free insulation, and additional equipment assistance for qualifying households.
Heat pump water heaters use 60-70% less electricity than standard electric tanks. Instant rebate applied at purchase.
Air-source heat pump rebates through NHSaves. Available from all four NH utilities.
NH solar pricing at $3.03/W average. NEM 2.0 credits at ~85% retail. Property tax exempt in 66% of towns.
NHSaves offers two tiers of the Home Performance program. Both include the same comprehensive assessment -- the difference is cost and rebate depth.
Available to all 4 NH utility customers
At or below 200% FPL or on utility discount rate
Also eligible if enrolled in LIHEAP, SNAP, Medicaid, SSI, Fuel Assistance, or utility low-income discount rate.
Key distinction: NHSaves rebates are direct rebates funded by NH ratepayers, not federal tax credits. They are unaffected by the federal expiration and remain fully available in 2026. The $100 HPwES assessment, 75% insulation discount, and $750 HPWH rebate all continue as normal.
All four of New Hampshire's electric utilities participate in NHSaves. Same programs, same rebates, regardless of your utility.
Greater Manchester, Concord, Nashua, central and southern NH — serves ~71% of NH electric customers
Salem, Derry, Plaistow, parts of southern NH — serves ~6% of NH electric customers
Seacoast (Exeter, Hampton) and Capital region (Concord area) — serves ~11% of NH electric customers
Rural NH, Lakes Region, White Mountains, Plymouth, Meredith — serves ~12% of NH electric customers
No subsidized financing in NH
Unlike Connecticut (Smart-E Loan at 0.99% APR) or Massachusetts (HEAT Loan at 0%), New Hampshire does not offer a statewide subsidized low-interest loan for energy efficiency improvements. Some individual utilities offer on-bill financing. Most NH homeowners use home equity loans or personal loans at market rates.
NHSaves is the unified brand for New Hampshire's utility-administered energy efficiency programs. It is jointly run by all four NH electric utilities: Eversource NH, Liberty Utilities, Unitil, and NH Electric Coop (NHEC). Every NH electric customer already pays into the program through a system benefits charge on their electric bill. NHSaves is not a separate company -- it is a coordinated program umbrella that ensures consistent rebates and services across all four utilities.
The standard Home Performance with ENERGY STAR (HPwES) assessment costs $100 as a copay. The actual value is $400-$600. During the assessment, the technician installs $150-$400 in free items (LEDs, smart power strips, showerheads, aerators, pipe insulation), so the $100 copay is effectively recovered. Income-eligible households through Home Performance Direct pay nothing -- the assessment and all installations are 100% free.
Yes. The HPwES assessment is required before you can receive the 75% insulation rebate (up to $8,000 per project). The assessment identifies what insulation measures your home needs and determines your specific rebate amounts. Without an HPwES on file, you cannot access insulation rebates or air sealing rebates through NHSaves.
Yes. All four NH utilities -- Eversource NH (~71%), Liberty (~6%), Unitil (~11%), and NHEC (~12%) -- participate in NHSaves and offer the same core programs and rebate amounts. The HPwES assessment, insulation rebates, HPWH rebate, and income-eligible programs are identical across all four utilities.
No. The federal Section 25C energy efficiency tax credit (which previously covered insulation and water heaters) and Section 25D residential solar tax credit both expired on December 31, 2025. They provide $0 in 2026. NHSaves rebates are direct rebates funded by NH ratepayers, not tax credits, so they are unaffected by the federal expiration and remain fully available.
No. Unlike Connecticut (Smart-E Loan at 0.99% APR) or Massachusetts (HEAT Loan at 0%), New Hampshire does not offer a statewide subsidized low-interest loan for energy efficiency improvements. Some individual NH utilities offer on-bill financing, but terms vary. Most NH homeowners use home equity loans, personal loans, or HVAC dealer financing at market rates.
You qualify for Home Performance Direct (income-eligible) if your household income is at or below 200% of the Federal Poverty Level (FPL). For a household of four, this is approximately $62,400 per year. You also qualify automatically if you are enrolled in LIHEAP, receive SNAP benefits, are on Medicaid, receive SSI, or are on a utility low-income discount rate. Call 603-229-2727 to verify your eligibility.
NHSaves offers a $750 rebate for qualifying heat pump water heaters (HPWHs) with a Uniform Energy Factor (UEF) of 2.0 or higher. Popular qualifying models include the Rheem ProTerra, A.O. Smith Voltex, and Bradford White AeroTherm. The rebate is available through all four NH utilities. No federal tax credit is available for HPWHs in 2026.
