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 Irmo, SC?

How do I report a power outage in Irmo, SC?
Report it to your electric utility — crews are dispatched from customer reports. Utilities tracked in Richland County include Dominion Energy South Carolina, Mid-Carolina Electric Cooperative; 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 Irmo specifically, or the whole county?
Both, and for Irmo we have the city-level view: Mid-Carolina Electric Cooperative has published outages for Irmo under its own name, most recently seen on 2026-08-17. When Irmo is affected, you get its own customers-out count and restoration time, with the Richland County county-wide total shown separately as context. Don't add the two together — the county figure already includes Irmo.
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.
