Key takeaway
When the power goes out in Holliston, report it to Eversource at 1-800-592-2000 or through the Eversource website or app, then follow restoration on the Eversource outage map. Sign up for the town's emergency notifications so you hear about road closures and warming centers. If you lose power often, a home battery, a generator or both can keep your essentials on.
Who this is for: Holliston homeowners who want to know who to call when the lights go out, how to prepare and which backup options are worth it.
Holliston's trees are a big part of why people love living here, and they're also why the power goes out. One heavy limb on a line can leave a whole street dark. Patch has reported storms that knocked out power to hundreds of Holliston homes at once, and in one bad storm more than a third of the town's Eversource customers lost power, with the utility warning that some outages could last days.
How to Report a Power Outage in Holliston
Eversource delivers electricity everywhere in Holliston, so outages go to Eversource, not the town or the police:
- Phone: 1-800-592-2000
- Online or app: report the outage and get updates through your Eversource account
- Text alerts: registered Eversource customers can sign up for outage updates by text
- Outage map: Eversource's map shows current outages in Holliston and estimated restoration times when they're available
Don't call 911 just to report an outage. Do call 911 for a downed wire, a fire or any emergency, and treat every fallen line as live.
What Causes Outages in Holliston
Most Holliston outages come down to weather and trees. Nor'easters with strong wind, heavy wet snow, ice storms and summer thunderstorms bring down branches and whole trees onto overhead lines. The town's wooded neighborhoods, especially along the back roads, can take longer to restore because crews have to clear trees before they can rebuild the lines. Car crashes into poles and equipment failures cause smaller, shorter outages. The Blizzard of 2026 in February left about 290,000 customers across Massachusetts without power at its peak, a reminder of how fast a big storm can stretch repair crews.
A Holliston Outage Checklist
- Register for Eversource outage texts and the town's emergency notification system before storm season.
- Keep flashlights, fresh batteries, a battery-powered radio and charged power banks in one spot.
- Store a few days of water, food that doesn't need cooking and any medications your family needs.
- If you're on a private well, remember the pump won't run without power. Fill some jugs before a storm hits.
- If you have a sump pump, have a plan for keeping the basement dry.
- Keep at least half a tank of gas in your car when big weather is in the forecast.
- Pay attention to town alerts for warming or charging centers during long outages.
Home Backup Power Options in Holliston
If outages are a regular problem at your house, you have three main choices:
- A home battery. A battery kicks in on its own when the grid drops and quietly runs your essential circuits, with no fuel to store. With solar panels on your Holliston home, it refills from the sun during the day, even while the grid is down.
- A generator. Standby and portable generators can run for days in a long outage as long as you have fuel. They're louder, need maintenance, and must be installed and used carefully to avoid carbon monoxide.
- Both. Some homeowners use a battery for the everyday outage and keep a generator for the rare multi-day storm.
Solar alone won't keep the lights on, because grid-tied solar shuts off during an outage to protect line workers. If you're torn between a solar battery or a generator, think about how long your outages usually last, noise, fuel and upkeep. A battery backup system can also earn payments through Eversource's ConnectedSolutions program.
