Geothermal Pilot Project in Framingham

Why Are We Doing This 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.

A geothermal system uses water, 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. This energy can be used to heat and cool indoor spaces and produce hot water in conjunction with geothermal heat pumps.

 

Where Is The Work Being Done?

A Framingham neighborhood with a mix of residential and commercial customers will be the site of the pilot project and the size and scope of the project will depend on the level of interest and eligibility. The technology may be expanded elsewhere based on the outcome of the pilot.

What Work Will Be Done?

There will be three parallel stages:

  1. Drill well fields
  2. Install main in the street/install service "Ts" for individual homes/buildings
  3. Work in customers' homes.

Each is not dependent on the other, but all three must be complete prior to starting up the network.

When Is The Work Being Done?

Field work began on the project in late September 2022. Construction and installation work is expected to take place in 2023.

Borehole-test-drilling 

Test boreholes were drilled at three locations along the pilot route:

  • Outside the fire station on Concord Street near Normandy Road
  • On Rose Kennedy Lane inside the Framingham Housing Authority complex
  • In Farley Parking Lot on the Mass Bay Community College campus on Normandy Road

The tests will help us determine how much heat we can put in and take out of the ground with our networked system.

With the results of these tests, we will evaluate the accuracy of our thermal capacity models and values so we can size the system appropriately moving forward.

Community Outreach

We're committed to engaging municipal officials, residents, businesses, community groups and neighbors about upcoming project activities.

Our efforts have included municipal briefings, direct mailings, on-site and virtual meetings, door-to-door outreach, and participation in community events. You can read updates in the most recent geothermal email. 

Featured Outreach: Framingham Earth Day Festival at Framingham Centre Common on April 23, 2022

geothermal-earth-day

Our geothermal pilot team met with a steady crowd of festival attendees who were interested in and excited about the networked geothermal pilot.

Visitors to our booth had the opportunity to take a closer look at the true-to-size heat pump model, our animated video explaining geothermal technology and our pilot, and kids and families enjoyed the Eversource globe squeeze balls they could take home with them.

Past events include:

  • Customer Meeting at Fuller Middle School in Framingham on April 13, 2022 - Information session where we connected with potential pilot participants who own homes or businesses along our proposed project routes.
  • Westborough Energy Fair at Mill Pond School on April 30, 2022 - We engaged with students and community members as enthusiastic about renewable energy technology as we are.
  • Framingham "Cooler Communities" event at Harmony Grove Elementary School on May 21, 2022 - We showed fourth graders that it can be "cool" to be involved in energy, especially when talking about home heating and cooling.
