Program Energy Mix

The information below describes the energy mix for the Standard Offering and the Greener Option.

For more detail, please download the most recent energy mix disclosure label (PDF).

Standard Offering

The Standard Offering includes approximately the same energy mix as National Grid Basic Service, including the same amount of renewable energy. Specifically:

  • 76.38% from a mix of traditional power sources, including natural gas, nuclear, oil, and coal, among others. (Download the most recent energy mix disclosure label for current percentages.)
  • 23.62% from a mix of clean energy sources that must be included to satisfy the 2018 Massachusetts Renewable Portfolio Standard (RPS) and Alternative Energy Portfolio Standard (APS). This includes a required 13% from newer New England-based renewable energy projects (MA Class I RECs). All electricity sold in Massachusetts must include the minimum amount of clean energy necessary to meet the Massachusetts RPS and APS requirements. These clean energy sources include solar, wind, landfill gas, and others.  Learn about the Massachusetts RPS and APS.

Greener Option

The Greener Option delivers 100% green energy. It includes 20% more energy from newer renewable energy projects in New England (MA Class I RECs) than the Standard Offering. The purchase of energy from these projects is viewed by many has having greater benefit than purchasing energy from other projects because it creates greater demand for building additional local renewable energy projects and it supports the jobs that go along with those projects.

The specific energy mix for the Greener Option includes:

  • 20% from newer New England-based renewable energy projects (MA Class I RECs)
  • 56.38% from wind projects outside of New England
  • 23.62% from a mix of clean energy sources that must be included to satisfy the 2018 Massachusetts Renewable Portfolio Standard (RPS) and Alternative Energy Portfolio Standard (APS). This includes a required 13% from newer New England-based renewable energy projects (MA Class I RECs). All electricity sold in Massachusetts must include the minimum amount of clean energy necessary to meet the Massachusetts RPS and APS requirements. These clean energy sources include solar, wind, landfill gas, and others.  Learn about the Massachusetts RPS and APS.
