In the exercise of its regulatory powers, the Enugu State Electricity Regulatory Commission (EERC) has ordered MainPower Electricity Distribution Company, formerly Enugu Electricity Distribution Company (EEDC), to refund over 20,000 estimated customers over “wrongful billing.”

This was contained in a public notice issued by EERC yesterday, where the Commission said that the move is a result of the complaints by MainPower’s customers against the firm’s overbilling.

“Under Section 35 of the Enugu State Electricity Law 2023 and other extant rules, this is to inform customers in Enugu State that the Commission has issued an Order to MainPower to refund the affected customers the overbilled units for energy consumed in April 2025,” the EERC notice reads.

It was gathered that the list of the affected customers has been published on the Commission’s website, while affected customers who have not been refunded within the timeframe should contact the Commission to request the necessary action.

Meanwhile, the order, signed by the Chairman of EERC, Chijioke Okonkwo, and the Commissioner in charge of Market Operations, Reuben Okoye, gave MainPower till July 2025 billing cycle to refund the customers, failing which it would pay a fine of N500,000 for each day that it fails to comply with the order in line with the extant law of the Enugu State Electricity Law, 2023.

According to the Commission, it started tracking the estimated billing practices of MainPower in October 2024 when it assumed full regulatory control in Enugu State from the Nigerian Electricity Regulatory Commission (NERC) and raised the issues with the firm in a letter dated December 16, which it said MainPower failed to adequately address in their response dated January 14, 2025.
