Statewide figures aggregate the same per-county records shown on each county page below; the statewide restoration figure is the typical (middle) value across the per-county typical times, weighted by how many records each county has. A county appears in a “widest area” month when that month produced one of its three largest recorded outages.

Common questions

How do I check power outages in Massachusetts?

This page lists live outage status for every county in Massachusetts, updated about every 15 minutes from the federal government's public county outage data (ODIN) and National Weather Service alerts, combined with utilities' own live data where we track them. Open any county for its restoration outlook, or search your ZIP or address for the most specific view.

Which utilities serve Massachusetts?

Electric utilities we track in Massachusetts include Eversource (CT/MA/NH), Hingham Municipal Lighting Plant (MA), National Grid (Massachusetts), Norwood Municipal Light Department (MA). Each restores its own service area — report an outage to your serving utility so crews can be dispatched.

When will power be restored in Massachusetts?

Restoration depends on the cause and scale of each outage, so it varies by county and utility. For each affected area with enough trend data we publish an independent restoration estimate — from the live outage count, the recovery rate, and weather — shown even before the utility posts an official time; very small or brand-new outages say so instead of guessing. Open an area above for its outlook.

How accurate are the estimates?

Every estimate is later graded against when the tracked outage was substantially restored (~90% of customers back), and the track record is published on our accuracy page. Statewide totals combine the federal county-by-county tally with utilities' own live outage data, so this page and the live map always show the same numbers.
