Geothermal Pilot in Framingham

An innovative heating and cooling system using renewable power from the earth.

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.

The  project was approved by the Massachusetts Department of Public Utilities and, once in service, the pilot is intended to run through two heating and cooling seasons (24 months). The planned route consists of  37 buildings, 32 of which are residential homes. 

We entered into an agreement with participating customers for the duration of the pilot, and will accept feedback before, during, and after the pilot period to ensure the best customer experience possible.

Groundbreaking

We hosted state and local leaders, along with clean energy partners, at MassBay Community College in Framingham on June 12 for the groundbreaking of our networked geothermal pilot. 

The event marked the start of construction on this innovative project, which is expected to be complete around October or early November in time for the heating season. 

“This is what fighting climate change on a local level looks like," said Vice President of Clean Technologies Nikki Bruno. “It’s not one entity. It’s all of us together: it’s customers, it’s agencies, it’s utilities, it’s advocates. This is a powerful moment for us.” 

Other speakers at the event included HEET co-executive director Zeyneb Magavi, State Rep. Priscila Sousa, Eversource President of Gas Distribution Bill Akley, Framingham Mayor Charlie Sisitsky, and Eversource President, CEO and Chairman Joe Nolan.  The full livestream can be watched on Facebook.

“Operating, constructing and maintaining an underground geothermal network has a lot of parallels to what our industry and our employees do every day,” explained Bill. “This project, for us, is enabling our group of dedicated employees to see a way that we can provide different services in a different way.” 

“This is truly an example of a real win-win for everybody as we move forward to this clean energy future,” added Joe Nolan. ​​​​​​​

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.
