| Utility information | Our restoration forecast |
|---|---|
| Official ETA, when the utility posts one | Independent estimated return window when trend data allows — often available first |
| Utility-reported status & customer counts | Confidence range + whether the outage is growing, stable, or restoring |
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 19, 7,878 completed outages have been graded this way — median error 2 hours across the most recent 600 of them (about 1.9 days), and we publish the misses. See the full record (how it works). Independent and unofficial: never the utility's commitment.

Common questions
When will my power be back on in Longmont, CO?
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 Longmont area — shown even before your utility posts an official restoration time. Check the live power outage status at the top of this page.
How do I check the power outage status in Longmont, CO?
This page is a live power outage status check for the Longmont 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 Longmont ZIP code — 80501, 80502, 80503, 80504 — 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 Longmont, CO?
Report it to your electric utility — crews are dispatched from customer reports. Utilities tracked in Boulder County include Xcel Energy; 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 Longmont specifically, or the whole county?
Right now, the Boulder County county-wide view, which covers Longmont. No utility outage map we follow has yet listed an outage for Longmont by name; utilities here have so far reported only county-wide totals, or used area names we cannot match to Longmont. If that changes during an outage, the city's own count and restoration time appear here automatically. Frederick (8 mi SE) is the closest place we track separately.
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.
