Who Do I Call to Report a Power Outage in Connecticut?
Contact your electric delivery utility directly. Connecticut has two investor-owned utilities that together serve nearly all of the state's 1.7 million electricity customers. Even if you've switched to an alternative electricity supplier, your delivery utility is still responsible for the wires, outage response, and power restoration.
| Utility | Outage Hotline | Service Area |
|---|---|---|
| Eversource | 1-800-286-2000 | Most of CT (Hartford, New Haven suburbs, Fairfield County, NW CT) |
| United Illuminating | 1-800-722-5584 | Greater Bridgeport & New Haven (Bridgeport, Milford, Shelton, Stratford, West Haven, and more) |
A small number of Connecticut towns are served by municipal electric utilities — including Wallingford Electric Division, Norwich Public Utilities, Groton Utilities, South Norwalk Electric & Water, and Bozrah Light & Power. If you live in one of these towns, contact your municipal utility directly. In an emergency involving downed power lines, call 911 immediately.
About This Data
This tracker aggregates live outage data from Connecticut's two main electric utilities. Eversource (formerly Connecticut Light and Power) is the larger utility, delivering electricity to approximately 1.3 million customers across most of the state — from Fairfield County in the southwest to the Quiet Corner in the northeast. United Illuminating, now part of AVANGRID, serves about 340,000 customers in the greater Bridgeport and New Haven areas along the coast. Together they cover virtually all of Connecticut's electricity customers.
Connecticut is a deregulated electricity market — customers can choose a competitive supplier for their generation, while Eversource or United Illuminating handles delivery, metering, and outage restoration. The grid operates within ISO New England, the regional transmission organization for the six-state New England region. The Public Utilities Regulatory Authority (PURA) regulates utility operations and sets delivery rates. For national outage data, see our national power outage tracker.

Who do I call to report a power outage in Connecticut?
Call your electric utility's outage hotline. Connecticut has two main delivery utilities: Eversource at 1-800-286-2000 (most of the state) and United Illuminating at 1-800-722-5584 (Bridgeport, New Haven, and surrounding towns). Even if you buy your electricity supply from a third-party supplier, your delivery utility handles outage restoration. You can also report outages through the Eversource or UI mobile apps and websites.
How does the Connecticut electricity market work?
Connecticut is a deregulated electricity market. Customers can choose a competitive electricity supplier for the generation (supply) portion of their bill, while their delivery utility — either Eversource or United Illuminating — continues to own and maintain the power lines, handle outage restoration, and read meters. If you don't choose a supplier, you receive "standard service" supply at a rate set by the Public Utilities Regulatory Authority (PURA). The grid operates within ISO New England, the regional transmission organization managing the power grid across all six New England states.
What causes power outages in Connecticut?
Connecticut's most frequent outage triggers are nor'easters and tropical storms that bring heavy wind, rain, and snow. The state's dense tree canopy — particularly oaks and maples along residential streets — makes it highly susceptible to tree-related outages during storms. Summer thunderstorms with microbursts and lightning strikes are common warm-weather causes. Winter ice storms can coat power lines and tree branches, causing widespread failures. Connecticut's coastal location also exposes it to hurricane remnants and tropical storm damage along the shoreline.
How long do Connecticut power outages typically last?
Most isolated outages in Connecticut are restored within 1 to 3 hours. Storm-related outages from nor'easters or severe thunderstorms typically last 4 to 24 hours. Major events — like Hurricane Isaias in 2020 or Tropical Storm Irene in 2011 — have caused outages lasting a week or more for some customers. Eversource and United Illuminating both publish estimated restoration times on their outage maps and send automated text/email alerts. PURA has established performance standards requiring utilities to restore a certain percentage of customers within specific timeframes after major storms.
