If you've never shopped, you're on Basic Service from your utility. Basic Service prices reset on a set schedule, typically every six months, which makes it easy to know when to compare again.
Municipal aggregation is widespread in Massachusetts: hundreds of cities and towns buy power for residents, and you can opt out at any time.
With a typical Massachusetts bill of about $172, supply is roughly $95 of it. A supply price 10% below your current default rate would save about $9 a month ($114 a year); delivery charges don't change.
Have your utility account number ready, compare offers on Energy Switch Massachusetts (energyswitchma.gov), the state's comparison site, and sign up with the supplier you choose. The supplier arranges the switch with your utility and your power isn't interrupted. Note when any fixed rate ends, because many suppliers then move you to a variable rate.
Your utility delivers the power and stays the same whichever supplier you choose. Its name is at the top of your bill.
