| 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.

How do I report a power outage in Dardenne Prairie, MO?
Report it to your electric utility — crews are dispatched from customer reports.

Does this page show Dardenne Prairie specifically, or the whole county?
Right now, the St. Charles County county-wide view, which covers Dardenne Prairie. No utility outage map we follow has yet listed an outage for Dardenne Prairie by name; utilities here have so far reported only county-wide totals, or used area names we cannot match to Dardenne Prairie. If that changes during an outage, the city's own count and restoration time appear here automatically. O'Fallon (2 mi N) 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.
