The Enugu State Electricity Regulatory Commission (EERC) has ordered MainPower Electricity Distribution Company to refund over 20,000 customers who were overbilled in April 2025, citing widespread breaches of estimated billing regulations.
This directive, issued in a joint statement on Monday by EERC Chairman Chijioke Okonkwo and Commissioner for Market Operations Reuben Okoye, followed a detailed investigation into MainPower’s billing practices, which revealed growing non-compliance with the regulatory cap on estimated billing.
“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.
The list of affected customers is available on the Commission’s website, and MainPower has until the July 2025 billing cycle to complete the refunds. Failure to comply will result in a daily fine of ₦500,000, in accordance with the Enugu State Electricity Law, 2023.

EERC noted that it had been monitoring the company’s billing system since October 2024 and had issued multiple warnings over rising customer complaints. It said MainPower’s April billing report showed a jump in estimated billing violations—from 24 percent in February and March to 34 percent in April.
“The Commission’s review confirmed that MainPower’s compliance has deteriorated significantly, necessitating this enforcement action,” the statement added.
Customers who do not receive their refunds by the deadline are urged to contact the Commission via email at info@eerc.en.gov.ng or call 09122642755.
