When's the power back on in Groton, CT?
Track current power outages in Groton, Connecticut — customers reported out, restoration progress, active weather alerts, and an independent restoration estimate. Groton is a city in New London County; when the serving utility's public feed reports Groton directly, this page shows the city's own outage count and restoration time, with the county-wide view as context.
Who serves Groton — and how this estimate works
Serving utilities tracked for New London County include Eversource (CT/MA/NH). The estimate uses changes in the reported outage count, restoration progress, current weather, outage size, and available local history. It is independent and unofficial — when a utility posts an official restoration time, both are shown separately. We score our own estimates against what actually happened on the accuracy page. Outages below 5 customers are too small for a meaningful area-wide estimate — the page says so instead of guessing.
Common questions
When will my power be back on in Groton, CT?
It depends on the cause and how many crews are working. When's the Power Back? combines the live outage count, the current restoration rate, weather, and local history into an independent estimate for the Groton area — shown even before your utility posts an official restoration time. Check the live status at the top of this page.
How do I report a power outage in Groton, CT?
Report it to your electric utility — crews are dispatched from customer reports. Groton is served by Eversource (CT/MA/NH); use the utility's outage line or website. Reporting a downed line helps crews find the fault faster. In a life-threatening emergency, call 911.
Does this page show Groton specifically, or the whole county?
Both. When your serving utility's public feed reports Groton directly, this page shows the city's own outage count and restoration time; otherwise it shows the New London County county-wide view, which still covers Groton.
How accurate is the restoration estimate?
Every estimate is later graded against when power actually came back, and the track record is published on our accuracy page. Estimates firm up a few hours into an outage once a steady restoration trend appears; very small outages are marked "too small to estimate" rather than guessed.
