Power in Massachusetts

With fossil power plants in Boston, Everett, Framingham, New Boston, West Medway, and North Weymouth. Exelon provides jobs and reliable, affordable power to nearby communities. We are dedicated to minimizing our impact on the environment and improving the communities we serve.

Economic Development

Exelon’s fossil plants in West Medway, New Boston, and Framingham are peaking units, which can be used during times of peak energy demand.  In total, the Exelon fleet in Massachusetts paid $32 million in taxes in 2012.

Exelon’s merger with Constellation expands Exelon's fleet with the additions of Mystic and Fore River power plants. Constellation employs 225 residents in the state.

Constellation provides commercial, industrial, public sector and government agencies, municipalities and utilities with a comprehensive array of products and services to meet electricity, and sustainability needs. Constellation also provides competitive pricing for electricity, as well as renewable energy options for residential customers.

 

Environmental Commitment

One of the ways Exelon accomplished its 2020 GHG emissions reduction goal was by retiring a less efficient and higher-emitting fossil fuel power plant in Massachusetts.

The latest addition of Mystic 8 and 9 and Fore River combined cycle gas turbines (CCGT) build on the company’s commitment to clean energy as part of Exelon 2020 by adding highly-efficient units that provide clean generation fueled by natural gas.  In Massachusetts, Exelon can produce over 2,000 MW of electricity from CCGT’s located at Mystic and Fore River.

Constellation also works with its retail and wholesale customers to reduce energy consumption and offers renewable and sustainable options including:

  • Solar
  • Energy Efficiency
  • Renewable Energy certificates
  • Load response solutions

Community Involvement

Exelon is committed to strengthening the community in which we live and serve.
