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.

Offshore Wind  

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

We have at least 4,000 megawatts of total development opportunity in partnership with Orsted, the largest developer of offshore wind in the world. 1,700 megawatts are under contract and in advanced development, including the first utility-scale offshore wind farms for New York and Connecticut.

Our existing projects will provide enough clean energy to power more than 1 million homes, with the ability to double that amount as we add additional projects to our lease area off the coast of New England.

Offshore wind is set to play a critical role in delivering well-paying green jobs and providing local economic investment that will benefit communities throughout the region as the country, and particularly the Northeast, look to meet ambitious clean energy goals.



We're dedicated to raising solar awareness in our territory and connecting our customers' solar generation to the grid.

We have owned and operated solar energy facilities since 2010, and today, our solar portfolio can power more than 11,000 homes.

These sites are estimated to save nearly 36,000 metric tonnes of carbon per year—the equivalent of taking 7,600 cars off the road. Four of our solar facilities are located on landfill or brownfield sites, which have few alternative uses. 

Storing Energy for Future Use

We're developing innovative battery energy storage projects that will help defer traditional infrastructure investments and store renewable energy for peak hours.

Using batteries to store power can improve reliability, help manage demand and reduce the need to build new power lines.

We're the first utility in Massachusetts to receive approval from the Department of Public Utilities (DPU) for grid-scale energy storage and we are currently constructing the first project in Provincetown on Cape Cod.

We are evaluating additional projects in Massachusetts, Connecticut and New Hampshire for the future.

The Road to Clean

We're also driving the future of lower emissions by helping to power electric vehicles.
