The Greenfield Light & Power Program is a City electricity aggregation program, which is a group electricity purchasing program for Greenfield residents and businesses.

The Greenfield Light & Power program gives electricity customers in Greenfield a City-vetted alternative to Eversource’s Basic Service and other electricity supply offers in the marketplace, cleaner electricity, and long-term, stable pricing (though savings compared with Eversource’s Basic Service cannot be guaranteed).

Cleaner electricity and consumer-friendly choices

You may choose between three options in Greenfield Light & Power:

  1. Standard: Provides electricity that is 100% from renewable sources, primarily wind projects outside of New England. Standard is default program offering, which means new participants will be automatically enrolled in Standard if another option is not chosen.
  2. Local Green: Provides electricity that is 100% from “premium” renewable sources in the New England region. By opting up to Local Green, you increase the demand for renewable energy produced in New England, which drives the development of new renewable energy projects on the New England power grid.
  3. Budget: Provides only the minimum amount of your electricity required by law from renewable sources, but is the least expensive option in the program.

How to participate

All new electricity accounts in Greenfield will be automatically enrolled in the Greenfield Light & Power Program within a few months of being opened, unless they choose to opt out. (You will receive a letter in the mail before being automatically enrolled with program information.) If you are not currently enrolled and wish to enroll, you may enroll online or with a phone call. Learn more.

Compare the cost

Use the online calculator to compare the program price with the most recent 12-month average of Eversource’s Basic Service prices and to see the greenhouse gas emissions avoided by participating in the Greenfield Light & Power Program. Or you can compare program prices with Eversource’s current 6-month Basic Service price.

How it works

A municipal electricity aggregation is a group electricity purchasing program. Participating in Light & Power Program will change your electricity supplier and the price Eversource uses to calculate the supply charges on your electricity bill, but participating will not replace Eversource as your electric utility. You will continue to call Eversource if your power goes out, and you will continue to receive your electricity bill from Eversource. If you are eligible for a low-income discount, you will continue to receive that discount with no change. Learn more.


Understand your bill

Greenfield Light & Power makes only minor changes to the way your electricity bill looks. But when you know what those changes are, you can use your bill to confirm whether you are enrolled and which program option you are enrolled in.

Savings cannot be guaranteed

Please note that, while the Greenfield Light & Power Program offers the potential for savings when compared with Eversource’s Basic Service price, there is no guarantee of savings. This is because Eversource’s prices change every 6 months for residential and commercial customers and every 3 months for industrial customers, and their future prices are unknown.

Protect your electricity account number

Eversource will never knock on your door or call you to talk about your electricity bill.
Only provide your electricity account number if you are ready to change your electricity supplier.
