How the forecast works: we analyze how quickly customers are being restored, whether the outage is still growing, current weather, outage size, and similar past outages in this area. Every completed forecast is compared with when power actually returned. As of Aug 29, 10,280 completed outages have been graded this way — median error 1.6 hours across the most recent 600 of them (about 2.6 days), and we publish the misses. See the full record (how it works). Independent and unofficial: never the utility's commitment.

How do I check the power outage status in Thornton, CO?
This page is a live power outage status check for the Thornton area: current customers out, the affected areas on the map, and an independent restoration forecast when enough trend data is available, refreshed about every 15 minutes from utilities' own outage maps and the federal government's county outage data. To narrow it to your own street, search a Thornton ZIP code — 80241 — and the map opens on that area. Your utility's own outage map remains the official word for your account.
How do I report a power outage in Thornton, CO?
Report it to your electric utility — crews are dispatched from customer reports. Utilities tracked in Adams County include Morgan County Rural Electric Assn, Southeast Colorado Power Assn, United Power and others; confirm your own provider, then use its 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 Thornton specifically, or the whole county?
Both, and for Thornton we have the city-level view: Southeast Colorado Power Assn and Xcel Energy have published outages for Thornton under its own name, most recently seen on 2026-08-17. When Thornton is affected, you get its own customers-out count and restoration time, with the Adams County county-wide total shown separately as context. Don't add the two together — the county figure already includes Thornton.
How accurate is the restoration estimate?
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. 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.
