In a statement signed and released by EERC Chairman, Chijioke Okonkwo, and the Commissioner in charge of Market Operations, Reuben Okoye on Monday, the commission said the order followed a thorough investigation into the company’s billing practices, which revealed a significant increase in estimated billing violations.
“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 stated that the list of affected customers has been published on the commission’s website, and MainPower has until the July 2025 billing cycle to complete the refunds.
It warned that failure to comply with the order will attract a fine of N500,000 for each day of non-compliance, as stipulated in the Enugu State Electricity Law 2023.
The commission made it known that it has been monitoring the disco’s billing practices since October 2024, and had issued several letters to the company, highlighting its concerns.
Despite this, EERC claimed the company failed to adequately address the issues, which prompted the commission to take enforcement 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.
The commission, however, advised affected customers who did not receive their refunds by the deadline to contact them via email at info@eerc.en.gov.ng or call 09122642755 for assistance.
