Massachusetts Heat Pump Electric Rate: What It Is and Who Qualifies

A heat pump electric rate is a utility pricing plan that charges homes heated by heat pumps differently in winter, usually to make electric heating more affordable. Massachusetts utilities, including National Grid and Eversource, have introduced seasonal heat pump rates for eligible customers. Terms, eligibility and enrollment change, so check with your utility for the current Massachusetts heat pump electric rate. Here is what these rates are, who may qualify and other ways to lower your heating bill.

Key Takeaways

• Seasonal heat pump rates exist. They are aimed at homes that heat with heat pumps.
• Your utility sets the rules. National Grid and Eversource each have their own terms.
• Light plant towns are different. Municipal utilities set their own rates.
• Enrollment may not be automatic. Ask your utility how to sign up.
• Efficiency still matters most. A well-sized system in a sealed home keeps bills down.

What Is a Massachusetts Heat Pump Electric Rate?

A Massachusetts heat pump electric rate is a special rate or discount for homes that use heat pumps as their main heat. Heat pumps raise winter electric use. Without a special rate, some homes see high winter bills even while total energy use goes down. State regulators and utilities have responded with seasonal rate options.

These rates typically lower some part of the winter electric charge for qualifying heat pump homes. The details, such as which months count and how much changes, vary by utility and can change over time. This guide does not list numbers, because they change. Your utility's website or customer service line has the current terms.

Who May Qualify?

• National Grid and Eversource residential customers with heat pumps as a main heat source may be eligible for their utility's heat pump rate.
• Whole-home heat pump homes are the usual focus. Partial installs may or may not qualify, depending on the utility's rules.
• Municipal light plant customers in towns like Peabody, Danvers, Marblehead, Reading and Wakefield should ask their light department about its own rates and programs.

Programs may require proof of a heat pump, like an invoice or model numbers. Keep your installation paperwork, the same records you need for a Mass Save heat pump rebate.

How Do You Sign Up?

1. Check your bill to confirm your electric utility.
2. Visit the utility's website or call customer service and ask about heat pump rates.
3. Ask whether enrollment is automatic or requires an application.
4. Have your heat pump model numbers and install date ready.
5. Ask when the rate takes effect and which months it covers.

As of 2026, these rates are still fairly new. Rules may change from one heating season to the next, so recheck each fall.

Other Ways to Lower Heat Pump Electric Bills

A special rate helps, but the biggest savings come from how the system is sized, set and maintained.

• Right-size the system. An undersized unit leans on expensive backup heat. See heat pump backup heat.
• Keep settings steady. Big setbacks can trigger backup heat. Read the best temperature to set a heat pump in winter.
• Seal and insulate. Mass Save has offered no-cost home energy assessments that find leaks.
• Maintain it. Clean filters and coils keep efficiency up.
• Choose efficient equipment. DOE rules require new split heat pumps to meet at least 7.5 HSPF2; cold-climate models go well beyond.

How Much Can a Heat Pump Lower Electric Use?

Compared with electric baseboard, quite a lot. Per DOE guidance on air-source heat pumps, a heat pump can reduce electricity use for heating by about 50%. ENERGY STAR cold-climate models must still deliver a COP of at least 1.75 at 5°F, per ENERGY STAR's heat pump criteria.

If you are coming from oil or gas, your electric bill will rise but your fuel bill goes away or shrinks. Compare the full picture in our pillar on heat pump cost in Massachusetts.

Plan for Lower Winter Bills

A Massachusetts heat pump electric rate can make heat pump heating more affordable, but only if you enroll and your system runs efficiently. Check with National Grid, Eversource or your light department each fall, and keep your equipment records handy.
