How do I check the power outage status in Riverton, WY?

How do I report a power outage in Riverton, WY?

Report it to your electric utility — crews are dispatched from customer reports. Utilities tracked in Fremont County include High Plains Power Inc; 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 Riverton specifically, or the whole county?

Both, and for Riverton we have the city-level view: High Plains Power Inc has published outages for Riverton under its own name, most recently seen on 2026-08-17. When Riverton is affected, you get its own customers-out count and restoration time, with the Fremont County county-wide total shown separately as context. Don't add the two together — the county figure already includes Riverton.

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.
