The Enugu State Electricity Regulatory Commission (EERC) has directed MainPower Electricity Distribution Company to pay back over 20,000 customers who were overcharged in their April 2025 electricity bills.
This instruction comes after a full investigation by the commission into the company’s billing methods. According to a joint statement from the EERC Chairman, Chijioke Okonkwo, and the Commissioner for Market Operations, Reuben Okoye, the commission discovered serious issues with the way MainPower was estimating and charging for electricity usage.
“The commission has issued an Order to MainPower to refund the affected customers the overbilled units for energy consumed in April 2025,” the statement read.
EERC has now published the names of the affected customers on its official website. MainPower is expected to finish the refund process before the July 2025 billing cycle. If it fails to do so, it will face a daily fine of N500,000 for every day the order is ignored, as required by the Enugu State Electricity Law of 2023.
The commission also noted that it had been keeping an eye on MainPower’s billing practices since October 2024. It sent several letters raising concerns, but the company reportedly did not take proper steps to fix the problem. As a result, the commission decided to take stronger action.
“The commission recently reviewed MainPower’s April 2025 estimated report, and observed that the degree of violation of the caps on estimated billing by MainPower had further deteriorated from the 24 percent observed in February and March 2025, to 34 per cent in April, 2025,” EERC stated.
Customers who are supposed to receive a refund but haven’t gotten it by the deadline can reach out to the commission by email at info@eerc.en.gov.ng or call 09122642755 to lodge a complaint and seek support.
