Clean Energy

Our future is clean energy. It's core to our commitment to lead our industry in sustainability and is a critical element of our business today and in the future.

We're dedicated to making our operations carbon neutral by 2030, and to bringing more clean and affordable energy to New England.

Building a Clean Energy Infrastructure

A clean energy future starts with a strong foundation. We're building the infrastructure our region needs to deliver clean energy to homes and businesses.

These projects will allow us to connect energy sources to our grid that are better for the environment.

  • We are delivering innovative solutions to lower emissions, improve reliability and integrate clean energy resources into our system. 
  • We are supporting the three states we serve in their aggressive GHG emission reduction goals as we invest in projects that will enable a cleaner grid. 
  • We are supporting the development of offshore wind, solar and energy storage — as well as innovative solutions like networked geothermal as a potential alternative to fossil fuel heating and cooling.
  • We are providing more opportunities for our customers to participate in the clean energy transition by offering them opportunities to adopt new technologies, such as electric vehicles, and helping them lower their energy use.


Offshore Wind

We are one of the nation's leading developers of offshore wind, serving as a catalyst for clean energy throughout the Northeast.

Networked Geothermal Heating and Cooling

Our pilot in Framingham, Massachusetts, is the first of its kind in New England, and will be an innovative way to provide clean and sustainable heating and cooling for customers.

Geothermal on a whole new level

Energy Storage

We're piloting an industry-leading, first-of-its-kind battery energy storage system in Provincetown, Massachusetts, designed to improve system reliability and provide clean backup power during outages.

How it works

Electric Vehicle Infrastructure

Our investment in local grid upgrades to support additional electric vehicle (EV) charging stations and the related educational resources we provide to our customers play a significant role in promoting the adoption of EVs.

Charging the future

Solar Energy

Our first projects to harness the power of the sun were installed more than 10 years ago, and today our 70 MW solar portfolio generates enough electricity to power more than 11,000 homes.
