Heat Pump Rate
Introducing the new Residential Heat Pump Rate
Starting November 1, 2025, a new reduced electric delivery rate will be available for qualified residential customers who use heat pumps for home heating. This seasonal rate applies to electricity usage from November 1 through April 30, helping reduce energy costs during colder months.
Who is qualified for the new Heat Pump Rate?
The Heat Pump Rate will be available to residential electric customers who use a heat pump to heat their home, either fully or partially. Please note that heat pump systems used only for air conditioning or water heating do not qualify.
How do I enroll in the new Heat Pump Rate?
If your Heat Pump was installed in your home with the support of a Mass Save® program in 2019 or later, and you’re on a residential electric rate, you may be automatically enrolled in this reduced rate. If you are eligible, you will see this new rate on your bill starting in November 2025—no action is needed on your part. We’ll send you a notification to confirm your enrollment by the end of October.
If you don’t receive an auto-enrollment confirmation from us and believe you should qualify, we'll make it easy to sign up. We’ll update this website with additional information as it becomes available.
If your Heat Pump was installed WITHOUT using a Mass Save® program or you’re unsure about how the heat pump was installed, you may still qualify for the Heat Pump Rate. We’ll provide instructions for enrollment when the application process opens.
Where can I see the Heat Pump Rate on my electric bill?

It could take one to two billing cycles after the new rate takes effect on November 1 for the discount rate to appear on your bill.
