Small said commissioners wanted to assure customers that their bills eventually would be "trued up" as their next bill would be based on an actual reading.
"In other words, after paying an estimated bill and the next bill based on actual usage, a customer will have paid no more than what was used," Small said.
Electric companies were not the only utility affected. Water, telephone and natural gas utilities also were affected by the storm.
West Virginia American Water said it was not necessary to take meter readers off their regular duties but some readers could not get to the meters because of heavy snowfall. Small said that means more customers could receive estimated bills.
Customers who lost water service can expect to see slightly lower bills due to decreased usage when meters can be read.
Small said telephone companies are required to pro-rate bills when services are interrupted for specified periods of time unless the customer causes the loss. She said customers who were without service could contact their telephone service provider to request a bill adjustment.
Small said some natural gas customers could receive up to three estimated bills in a row in situations where the gas meters were inaccessible or if there were safety concerns for company employees.
