Choose An Electric Supplier

Eversource customers have the option of choosing a competitive energy supplier.

Your monthly bill is broken into two main charges:

  • Supply: The cost of electricity itself. Eversource or a supplier pays to purchase this energy on your behalf from a pool of multiple energy producers at the current market price. This price can go up and down.
  • Delivery: The cost of delivering electricity. This is what we charge to bring energy to your home or business and maintain a safe and reliable system.

You should be sure to evaluate factors such as the length and terms of a contract with a supplier, cancellation fees or other related information.

If you choose a supplier, their rates will go into effect on your next scheduled meter reading date, provided Eversource received notice at least two business days prior to the meter reading.

Eversource will still deliver power to your home or business, read your meter, care for the poles and wires, provide customer service, and restore power when there is a service interruption.

Also, Eversource will never go door-to-door to discuss your Eversource bill or energy supply options. Our employees always carry identification, and you can always call us to see if we have sent someone to your home.

You also have the option of blocking your electric account from authorized switching to a third-party supplier from Basic Service. Call us at 800-592-2000 to add this protection to your account.

Available Resources

The Department of Public Utilities (DPU) licenses competitive suppliers within the Commonwealth of Massachusetts and maintains a list of current offers available from suppliers. This website also provides information to help you shop for a supplier that's right for you.

To see a list of competitive suppliers that may serve customers on your rate, visit our Competitive Suppliers page. You can also use our Competitive Supplier Calculator to compare an offer you receive with Eversource's Basic Service.

Important Questions To Ask

When considering an offer from a supplier, here are some important questions you should ask before making a decision. 

  • What is the length of the contract?
  • Is this a fixed or variable rate?
  • Do early termination fees apply?
  • Can I switch to another supplier?
  • Who do I contact if I have questions?
  • Are you licensed in the state, and what if I discontinue service in the region?

Recognizing Aggressive Marketing Tactics

Eversource customers continue to report receiving calls and visits from energy marketers misrepresenting themselves as Eversource employees.

These individuals may request to see a copy of your bill, offer discounted power or use other tactics such as authentic-seeming phone numbers, graphics, and uniforms to earn your trust.

A heightened awareness is critical to prevention and we’re taking an active role to help protect our customers.

To help evaluate your energy supply options and recognize dishonest marketing tactics please keep the following tips in mind:

  • Eversource does not call or solicit door-to-door on behalf of any competitive energy supplier. Customers are urged to always decline any door-to-door offers or requests to discuss energy rates from someone claiming to be an Eversource employee.
  • Never provide personal or financial information to anyone, in person, on the phone, or online, without verifying their credentials even if the individual seems legitimate or knows basic account information.
  • All Eversource employees carry company-issued identification, and any contractors working with us carry documentation explaining the nature and location of their work.
  • Call Eversource to verify any offers or requests, but don’t dial the phone number the individual provides. Always use our customer service phone numbers available by visiting the Contact Us page at

Municipal Aggregation

Some towns in Massachusetts have elected to purchase electricity in bulk on behalf of their residents. When a community opts for Municipal Aggregation (sometimes called Community Choice Electricity or Community Choice Aggregation), all residents on Eversource’s Basic Service will receive a letter from their town informing them of their supply rate and their ability to opt-out and continue receiving Basic Service.

As with any electric supplier, if you enroll in the aggregation, Eversource will still deliver power, read your meter, care for the poles and wires, provide customer service and restore power when there is a service interruption

If you have a question regarding your town's aggregation, please contact your town or supplier directly.

Large Business Customers

After choosing a supplier, if you are currently a large commercial or industrial Basic Service Fixed rate customer up to three months of your past billing will be recalculated to reflect the month-to-month Basic Service Variable rate. This adjustment may result in either a credit or debit.

Customer Information List

In order to expand the options available to electricity consumers in Massachusetts, the Department of Public Utilities (DPU) has established guidelines for the compilation of a Customer Information List. Eversource makes this list available to competitive suppliers licensed by the DPU for electricity marketing purposes only.

The Customer Information List includes the name on your electric account (corporate name, where applicable), your mailing and service addresses, monthly meter reading date, and rate class. In addition, your monthly kilowatt-hour usage (and demand where applicable) for the previous twelve months at your current location will be included. The list will be updated on a quarterly basis.

If you do not want your information included, please contact Eversource at 866-746-1110 or by filling out an online form.

You also have the option of registering with the Federal Trade Commission's Do Not Call list.
