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).

New prices and a new Budget option coming in January 2021

Beginning in January 2021, Greenfield Light & Power Program prices will change for all program participants, and for most, the price will lower. The program will continue to provide 100% clean, renewable electricity through both the Standard and Local Green offerings. In addition, the program will offer a new Budget option, which will provide only the minimum amount of renewable electricity required by state law (18% in 2021).

  • Active participants in the Greenfield Light & Power Program do not need to take any action to participate in the new contract in January. They will automatically receive the new prices.
  • Active participants may change to the Budget option online or by contacting customer support. New participants may select the Budget option when they enroll.

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.


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.
