What the program pays

Eversource Heat Pump Rebates and Rates incentive amounts

  • Massachusetts heat pump rebate (via Mass Save)

    Amount
    $500 to $10,000
    Status
    Open
    Notes
    Eversource is a Mass Save sponsor, so Massachusetts customers access rebates through the Mass Save program structure.

  • Connecticut heat pump rebate (via Energize CT)

    Amount
    $500 to $3,500
    Status
    Open
    Notes
    Delivered through Energize CT, tiered by income and system.

  • Seasonal heat pump electric rate

    Amount
    Rate rider, not a rebate
    Status
    Open
    Notes
    A discounted winter electric rate for qualifying heat pump customers. Not a rebate; a lower ongoing rate, and often worth more over ten years.
Amounts reflect published program terms as of the verification date above. Program terms change without notice, and several programs require pre-approval before installation.

Eversource is a useful case study in how state-level program design dominates utility-level branding. The same company name sits on top of three programs with very different rules and very different amounts.

Massachusetts

Eversource is a Mass Save sponsor, so a Massachusetts customer does not apply to an Eversource heat pump rebate. They apply through Mass Save, which reaches the largest amounts in the country for whole-home projects.

The thing Eversource actually provides on top is the seasonal heat pump rate, a discounted winter electric tariff for qualifying customers. This deserves more attention than it gets. Massachusetts electricity runs 29.61 cents per kilowatt hour, which is among the highest in the continental US. Over a 6,300 degree day winter, a meaningful rate reduction can beat a one-time rebate on total value, and it recurs every year.

Connecticut

The equivalent program is Energize CT, where heat pump rebates are generally tiered by income and system type and top out lower than Massachusetts. Connecticut electricity is somewhat cheaper than Massachusetts at 24.32 cents per kilowatt hour, but the operating cost case still depends heavily on what you are replacing.

Roughly 40 percent of Connecticut homes heat with oil, which is the highest oil share of any state outside Maine and Vermont. That makes the oil comparison the relevant one for a large share of Connecticut households, and the case there is strong.

New Hampshire

New Hampshire programs are administered jointly between the state and utilities, and the federal HEAR allocation has been working through launch during 2026. New Hampshire has expensive electricity at 27.01 cents per kilowatt hour and a 40 percent oil share, which is the same profile that makes Maine’s conversion case work.

How to sequence this

There are two separate processes and they are frequently confused. The rebate usually requires pre-approval through the state program before installation. The rate requires enrollment after installation with qualifying equipment documented.

Get both in writing before you sign. If a contractor only mentions one, ask about the other. The calculator will show you what the operating cost looks like at your current rate, which is the baseline you should compare the heat pump rate against.

Next steps

Confirm the reservation requirement first, because it is the single most expensive detail to get wrong. Then run the calculator, which applies only programs marked open in your state and will show you the after-rebate range alongside your modelled operating cost.

Check the heat pump cost guide if you want to sanity-check the installed band your contractor quotes, and the relevant comparison page if you are still deciding between fuels.

Ask Massachusetts, Connecticut, New Hampshire installers to price this job, not a different one

The range is already on this site, and the calculator will give you a ZIP-level number for free. What you do not have is a bid that uses the same scope. We send your ZIP and that range to installers who work the market, and we tell them to quote that job. You get the emails. You decide.

  • We attach the modeled range so the bid has to price that job, not a sales package
  • You also get a one-page brief you can hand to any contractor you found yourself
  • Phone is optional. No account. If nobody covers your ZIP yet, you still get the brief

Installers pay for the introduction in markets we cover. That is how the site is funded. Read the privacy policy and the money model.

Frequently asked questions

Does Eversource have its own heat pump rebate?
It depends on the state. In Massachusetts, Eversource is a sponsor of Mass Save, so rebates are delivered through the Mass Save program rather than a separate Eversource program. In Connecticut, the equivalent is Energize CT. In New Hampshire, programs are administered through the state and the utilities jointly. The Eversource heat pump rate, by contrast, is genuinely an Eversource product.
What is the Eversource heat pump rate and is it worth it?
It is a seasonal electric rate for qualifying heat pump customers, with a lower winter rate than the standard residential tariff. For a household running a heat pump through a New England winter, the difference can be worth more over ten years than the one-time rebate. It requires separate enrollment and a qualifying heat pump installation, so ask about it at the same time as the rebate.
Which state has the best Eversource heat pump incentive?
Massachusetts, by a wide margin, because the Mass Save program is larger and better funded than the Connecticut and New Hampshire equivalents. Massachusetts rebates can reach $10,000 for whole-home projects, while Connecticut tiers generally top out lower. If you are near a state line, that difference is worth knowing about, though program eligibility follows the service address.
Do I need a heat pump rate enrollment before installing?
The rebate usually requires pre-approval through the relevant program, and the rate requires enrollment after installation with documentation of qualifying equipment. The two processes are separate. Confirm both before you sign a contract, because a project that qualifies for one does not automatically qualify for the other.
How does Eversource electricity pricing affect the heat pump case?
Eversource territory spans some of the highest electricity prices in the continental US, with Massachusetts at 29.61 cents per kilowatt hour and Connecticut at 24.32 cents as of June 2026. That makes the operating cost case dependent on what you are replacing: strong against oil, contested against gas. The seasonal heat pump rate exists specifically to improve that math.
