How Do You Use the Eversource Outage Map?

The Eversource outage map provides an overview of reported power outages across Connecticut, Massachusetts, and New Hampshire. It helps customers locate affected areas, see how many customers are without electricity, and check available restoration updates. During severe weather or unexpected service interruptions, the map offers a convenient way to understand the extent of an outage and follow recovery progress.

How to Check Eversource Power Outages on the Map

To find outage information for your area, follow these steps:
  1. Open the official map: Visit the Eversource outage map on your phone or computer.
  2. Locate your area: Select Connecticut, Eastern Massachusetts, Western Massachusetts, or New Hampshire, then use the search bar or zoom controls to find your town or neighborhood.
  3. Identify reported outages: Look for colored markers indicating power interruptions. The map legend helps you understand the approximate number of customers affected.
  4. Review outage details: Click or tap a marker to view available information, such as affected customer counts, outage causes, and estimated restoration times.
  5. Check for updates: Revisit the map as conditions change, or use the available outage status and alert tools for information about your service.

How to Interpret Outage Markers and Restoration Updates

The Eversource power outage map uses colored markers to represent the scale of reported outages. Its legend groups affected customers into ranges, from 1–50 to more than 5,000. Larger clusters indicate more widespread interruptions, although a marker does not necessarily mean every home in the surrounding area has lost power.
Customer counts represent affected accounts rather than individual residents. Restoration estimates, when available, indicate when electricity is expected to return, but they are not guaranteed. Repair schedules may change as crews assess damaged equipment, remove fallen trees, or address additional safety hazards.
The map is updated approximately every 15–30 minutes, so newly reported outages and restoration progress may not appear immediately. If your home has lost power but no nearby outage is displayed, report the issue directly to Eversource rather than relying solely on the map.

How Do You Report a Power Outage to Eversource?

If your electricity goes out, first check whether the problem is limited to your home or affecting nearby properties. Even if the Eversource outage map already shows an interruption in your area, reporting your outage can help the utility identify additional problems and track affected customers more accurately.

How to Report an Eversource Power Outage

Eversource provides several ways to report a power outage:
  • Online: Visit the official Eversource outage page and select "Report a Power Outage." You can use your phone number or sign in to your Eversource account.
  • By phone: Contact Eversource through the outage reporting number for your service area, available on its official contact page.
  • Mobile options: Use Eversource's mobile app to access outage services and updates.
Before reporting, have your service address, account details or registered phone number ready. Describe any relevant conditions, such as nearby homes without power, damaged utility equipment, or fallen trees. Only report hazards you can observe safely from a distance.

Why Should You Report an Outage Even During a Major Storm?

Reporting an outage remains important during widespread Eversource power outages. Although utility systems can detect many interruptions automatically, individual reports may help identify smaller outages or areas that remain without electricity after larger repairs.
If you notice a new hazard, such as a fallen power line, damaged pole, or smoking electrical equipment, keep your distance and report it immediately. For downed wires, fire, or other life-threatening emergencies, call 911.
If the outage appears limited to your home's wiring, breakers, or electrical panel, a licensed electrician may be needed. However, if you're unsure whether the problem involves utility equipment, contact Eversource for guidance.

What Safety Steps Should You Take During an Eversource Power Outage?

During an Eversource power outage, your priorities should be staying safe, maintaining communication, and protecting essential needs such as food, medication, and lighting. Electrical hazards, carbon monoxide exposure, and food spoilage can pose serious risks, especially during storms or extended interruptions. Follow these essential safety precautions:
  • Stay away from downed power lines: Treat every fallen wire as live and dangerous. Keep children and pets away, avoid nearby water or metal objects, and report damaged power lines to Eversource or 911. If a wire falls on your vehicle, remain inside unless there is an immediate danger, such as fire.
  • Use generators safely: Operate fuel-powered generators outdoors, at least 20 feet away from doors, windows, and vents. Never run one inside a home, garage, or enclosed space, even with doors open. Keep battery-powered carbon monoxide detectors working to reduce the risk of poisoning.
  • Protect food and medication: Keep refrigerator and freezer doors closed as much as possible. An unopened refrigerator generally keeps food safe for up to 4 hours, while a full freezer can maintain safe temperatures for about 48 hours. Check storage requirements for refrigerated medication and contact a pharmacist if necessary.
  • Conserve power and communication: Use your phone's low-power mode, reduce screen brightness, and keep a portable charger available. Use flashlights or battery-powered lanterns instead of candles to reduce fire risks, and reserve phone calls for urgent situations.

What Should You Do During a Prolonged Power Outage?

When an Eversource power outage lasts for several hours or overnight, your focus should shift from immediate safety to managing essential needs and deciding whether it is safe to remain at home. Consider the following steps to protect your household during an extended outage:
  • Prioritize essential needs: Focus on medical equipment, necessary medications, safe lighting, and communication devices. Check on family members or neighbors who may need additional assistance, especially those who depend on electricity for medical or mobility equipment.
  • Manage food, water, and indoor conditions: Check whether refrigerated food remains safe, and keep drinking water available, especially if your home relies on an electric well pump. Watch for extreme indoor temperatures, frozen pipes, or other conditions that could make your home unsafe.
  • Monitor restoration updates: Check the Eversource outage map and sign up for available outage alerts rather than refreshing the map constantly. Conserve your phone battery by using low-power mode and limiting unnecessary activities.
  • Consider temporary shelter or backup power: If restoration is delayed and your home becomes too cold, too hot, or unsuitable for essential medical needs, consider staying with family, visiting an emergency shelter, or using a suitable backup power system. Follow local emergency guidance when deciding whether to relocate.

How Can You Prepare for the Next Eversource Power Outage?

Preparing before the next storm or unexpected Eversource power outage can help keep your household safe and comfortable. A practical emergency plan should cover essential supplies, communication, and reliable backup power. Even a few simple preparations can make a significant difference when electricity is unavailable for hours or longer.

Build an Emergency Kit and Communication Plan

Keep essential supplies in an accessible location and make sure everyone in your household knows what to do when the power goes out. Consider the following preparations:
  • Emergency supplies: Store flashlights, spare batteries, drinking water, nonperishable food, a first-aid kit, blankets, and necessary medications.
  • Communication plan: Save important phone numbers, choose an emergency contact, and decide who will check outage updates and report power interruptions.
  • Special household needs: Prepare supplies for children, pets, and anyone who relies on medical equipment, mobility devices, or refrigerated medication.
  • Regular checks: Review supplies periodically, recharge power banks, and confirm that emergency equipment works properly.

Prepare Reliable Home Backup Power

Portable power banks, rechargeable lanterns, and car chargers can help keep essential devices running during short outages. For longer interruptions, consider home battery backup solutions that can support larger household loads, such as refrigerators, lighting, and essential appliances.
For more comprehensive protection, the Anker SOLIX E10 Whole-Home Backup offers expandable battery storage and flexible backup configurations to help keep your home powered during unexpected outages.
Key features include:
  • Expandable battery capacity: Starts at 6 kWh and expands up to 90 kWh with a multi-unit configuration to meet different household energy needs.
  • Fast automatic switchover: Delivers backup switching in 20 ms or less with a compatible Power Dock setup.
  • Powerful home backup: Delivers 7.6–22.8 kW of rated output and up to 10–30 kW of temporary turbo output, depending on the configuration, to support demanding household appliances.
  • Flexible energy sources: Supports solar input and compatible generator integration for extended backup options.
By choosing a backup system that matches your household's essential loads and expected outage duration, you can stay better prepared for future power interruptions.
