Greenfield is using 100% green electricity with Greenfield Light & Power

Greenfield Light & Power Program

Welcome to the Greenfield Light & Power program, a Town electricity program designed to make 100% green energy available to Town residents and businesses cost effectively, while also offering stable, predictable pricing for electricity supply.

The program is an electricity aggregation. Allowed by Massachusetts law, electricity aggregation a form of group purchasing in which a town or city selects an electricity supplier on behalf of its residents and businesses. The program impacts the supply charges on your Eversource bill.

All Eversource Basic Service customers in Greenfield are automatically enrolled in Greenfield Light & Power unless they choose not to participate, which is known as opting out.

  • If you participate: Eversource will deliver your electricity, fix power outages, and send you a bill, but Greenfield will choose your electricity supplier. Your Eversource bill will show the program price as your electricity supply price.
  • If you choose not to participate: Eversource will continue to be your electricity supplier. This is known as Eversource Basic Service.

Program Options

Greenfield Light & Power delivers 100% green energy. Participants have access to two 100%-green options:

  • The Standard Offering: The is the default option. The Standard Offering gives you 100% green energy from a mix of sources. Program participants are automatically enrolled in the Standard Offering.
  • The Greener Option: This option allows you to make your electricity 100% green plus focus on locally produced renewable energy. Specifically, the Greener Option increases the amount of electricity from new renewable energy projects in New England from the minimum 12% required by the state in 2017 to 32%. (“New” renewable energy projects came into operation in 1998 or after.) To choose the Greener Option, call Public Power at 1-800-830-2944.
