Who is my electric company?

Enter your ZIP code to see the electric utilities serving your county, how many customers each has, and how to report an outage to them.

Last updated October 19, 2026

Your electric company is the utility whose lines reach your address, and your electric bill names it. Utilities report their service territory to the US Energy Information Administration (Form EIA-861) by county, not by address, so MassOutage lists every utility serving your county; usually only one of them serves a given address. That utility is also the one to call when the power goes out.

Find your electric company by ZIP code

Finding the one for an exact address

  • Your electric bill names the utility that delivers your power.
  • Without a bill, ask the utilities listed for your county: a utility can tell you whether it serves a given address.
  • A landlord or the previous occupant can tell you which utility served the home.

Electric utility or electricity supplier?

The utility listed here owns the lines to your home and restores power when it goes out. In some states you can buy the electricity itself from a separate retail supplier, which may also appear on your bill. Outages still go to the utility, not the supplier; each state's page below says how many of its customers buy from another supplier, from EIA-861.

By customers on their lines in every state they serve (US EIA-861, 2025). Each files with EIA under its own name, so the parts of one holding company are listed apart.

Who is my electric company: FAQ

Who is my electric company?
The utility whose lines serve your address. Enter your ZIP code on this page to see every electric utility with service territory in your county, from US EIA-861 filings, with the outage contacts MassOutage has on file. Your electric bill names the one that serves you.
How do I find the power company for my address?
Your electric bill names it. Without a bill, enter your ZIP code here to see the utilities serving your county, then ask them: a utility can tell you whether it serves a given address. Service territory is published by county, not by address, so MassOutage can't pick the one utility for an exact address.
Why does my county have more than one electric company?
Utilities report their service territory to the US Energy Information Administration county by county, and many counties are split between utilities, such as an investor-owned utility, a rural electric cooperative and a city-owned utility. Usually only one of them serves a given address.
Who do I call when the power goes out?
Your electric utility, the company that owns the lines to your home, even if you buy your electricity from a separate retail supplier. Use its outage phone line or website; MassOutage can't take outage reports. For a downed power line, stay at least 35 feet away and call 911.

Data from EIA Form 861 (utility reliability), every source we read. Service territory and customer counts are each utility's own EIA-861 filing; a utility a live outage feed has reported in a county is listed there too.
