Seven steps to switch in Massachusetts

  1. Find what you pay now. Your bill shows the price you pay for Basic Service. Write down that price and the date it will next change. It is your utility’s Basic Service price.
  2. Check that you can choose. Look at your bill. If your power comes from a city utility or a cooperative, it may sit outside the choice program, so confirm before you shop.
  3. Compare on the official site. Start with Energy Switch Massachusetts, which is run for consumers. Look at the price type, the term and the fees, not only the headline rate.
  4. Get the terms in writing. Ask for the price per kWh, whether it is fixed or variable, the term, every monthly fee, the early termination fee and what the price becomes at renewal.
  5. Sign up with the supplier. You enroll with the supplier, not with your utility. Keep the contract and any confirmation, and note how long you have to cancel.
  6. Watch for the start date and your first bills. Your utility handles the change. Expect a notice, and check that the supplier name, the price and the start date match what you were told.
  7. Mark the end of the term. Put the renewal date in your calendar. Many plans change price at the end of the term unless you choose again.

What we checked for Massachusetts

These points come from the regulator or its official shopping site, or from the supplier disclosure language that its rules require. Each names where it was read.

  • Energy Switch Massachusetts is the Department of Public Utilities’ shopping website for electric supply. Source: Energy Switch Massachusetts.
  • You have the right to rescind a supply agreement without charge or penalty within three days of receiving a fully executed copy, and a supplier may not start service until that period has expired. Source: Mass.gov, know your rights as a utility consumer.
  • A supplier cannot sell electric generation unless it holds a license from the department, and you cannot be switched without your consent. Source: Mass.gov, know your rights as a utility consumer.
  • Many towns run a municipal aggregation. If your town does, customers on Basic Service are usually enrolled automatically after a notice from the town, and you can opt out. National Grid says there is no fee to leave an aggregation. Source: National Grid Massachusetts, electric aggregations.

What to confirm before you sign in Massachusetts

We could not confirm these points from an official page, so we do not state a number for them. Ask the supplier, read the contract and check with the Massachusetts Department of Public Utilities.

  • Your town’s aggregation price and opt-out steps
  • Any early cancellation fee in a supplier contract
  • The date of your next default price change, so you compare offers against the right number

What a small price gap is worth

The average Massachusetts home used 596 kWh a month in 2025, or about 7,146 kWh a year. At that use, every 1 cent per kWh of difference between an offer and your utility’s Basic Service price changes the yearly bill by about $71. A gap of 2 cents is about $143 a year, and 0.5 cents is about $36.

Those numbers shrink or grow with your own use. A monthly fee of $5 adds $60 a year, which can erase a small price gap. Run your own numbers with the electricity bill calculator, and compare fixed and variable plans with the fixed vs variable rate calculator.

Compare the whole contract

A low first price is only part of a plan. Look at the term, the monthly fee, the early termination fee and the renewal price, then compare the full yearly cost.

Who still delivers your power

Switching does not change the company that owns the lines and the meter. In Massachusetts, the largest investor-owned utilities by residential customers in 2025 were:

If something goes wrong

Keep your contract, your confirmation and any call notes. If you think you were switched without permission, tell your utility and your regulator right away. The Massachusetts Department of Public Utilities takes complaints about suppliers.

Be wary of anyone who says they are from your utility and says you must switch, who asks for your account number before you have seen a contract, or who will not give you the price and fees in writing.

Switching electricity suppliers in Massachusetts

How do I switch my electricity supplier in Massachusetts?

Compare offers on Energy Switch Massachusetts, choose a supplier, get the price, term and fees in writing and enroll with the supplier. Your utility handles the change and keeps delivering your power.

Can I cancel after I sign in Massachusetts?

You have the right to rescind a supply agreement without charge or penalty within three days of receiving a fully executed copy, and a supplier may not start service until that period has expired.

Do I still get a bill from my utility?

In most cases yes, and your utility still delivers the power, owns the meter and restores service after an outage. Some suppliers send their own bill, so read the contract.

Sometimes. It can also cost more. Compare the offer with your utility’s Basic Service price over a full year, and include fees and the renewal price.
