FRANKFORT, Ky. — Customers of Kentucky Power will see their bills go up next month, following a court decision that the Kentucky Public Service Commission didn’t take into account required expenses during the utility’s 2023 rate case.

That year, Kentucky Power had sought permission to raise rates by more than 18 percent, but the PSC denied the request and granted an rate hike of less than 6 percent. The PSC justified the revision by disallowing more than $14 million in transmission and rate case expenses.

Kentucky Power appealed the decision in court and was successful. Now, the PSC has revised Kentucky Power rates to allow a surcharge of about half a cent per kilowatt-hour. That surcharge will expire after 22 months, or in August 2027.

The change shouldn’t mean a big increase for most customers. The average residential customer using 1,200 kilowatt-hours per month would see their bills rise by about $6.

Kentucky Power is currently in the middle of another request to raise rates by about 15 percent. That case is still undecided.
