Geothermal Pilot Program for Eastern Massachusetts

We are in the planning stages of an innovative heating and cooling system for one neighborhood

What is Geothermal Energy?

The networked geothermal system uses wells, piping and pumps to pull the earth's heat out of the ground to warm buildings in winter and pumps heat from buildings back into the ground in summer to cool them. More specifics are available from the U.S. Department of Energy.

This technology is in everyday use in the U.S. and around the world. We're piloting its use at scale as a potential option to complement or replace delivered fuels and natural gas service for heating and cooling.

About Our Pilot Program

Quick Facts

  • We will select a mixed group of about 100 residential and commercial or industrial customers in the same neighborhood from the list of interested participants
  • The area is within Eversource natural gas service and currently includes delivered fuels (heating oil or propane) customers.
  • Eversource will enter into an agreement for the duration of the pilot, which will be three years.
  • We'll be accepting feedback before, during and after the pilot to ensure the best experience possible.

What Pilot Customers Receive

  1. A cost-effective, low-carbon source of heating and cooling. Based on our review, geothermal energy can reduce the average residential customer's carbon emissions by up to 60 percent.
  2. Eversource will cover the cost of all the equipment to be installed in homes and businesses.
  3. Eversource will also pay for, and be responsible for, all equipment, installation and maintenance costs of the networked geothermal system outside of the homes and businesses.
  4. Customers will not be responsible for any commodity charges for heating and cooling for this pilot. The geothermal energy is free. We expect a low monthly fee for customers that will be used to fund this pilot.
  5. The technology is proven, but if something isn't functioning as planned or customers want an alternate heating and cooling service, we will work to ensure the continued heating and cooling of property for personal comfort.


We're currently working to identify the pilot location and customers. We anticipate finalizing the ultimate location in the fall timeframe this year. 

We anticipate designing the system over this upcoming winter and installing the system in the spring of 2022, with the final pilot in-service to follow.

We will continue to post updates on our progress here.
