Our First-of-its-Kind Pilot Uses Utility-Scale, Networked Geothermal

A 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.

It is renewable energy that comes from the sun's rays and temperatures produced in the earth's core.

We're piloting its use at scale in Framingham as a potential option to complement or replace delivered fuels and natural gas service for heating and cooling. The use of this technology could be expanded in the future based on the outcome of the project. 

About the Project

We're committed to delivering New England's vision of a clean energy future, and determining if networked geothermal systems are a viable option to affordably heat and cool homes and businesses.

What Pilot Customers Receive

1. A cost-effective, low-carbon source of heating and cooling.
2. We pay for the cost of building and installing the geothermal system, as well as all the equipment to be installed in homes and businesses.
3. Participants will pay a low fixed charge each month for access to the geothermal network. They will be responsible for their electric bill that will power the heat pump. However, their monthly energy costs should ultimately decrease because they will no longer be primarily paying for natural gas or delivered fuels to heat and cool their homes and businesses.
4. 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.
