The Enugu State Electricity Regulatory Commission (EERC) has directed MainPower Electricity Distribution Company, formerly known as Enugu Electricity Distribution Company (EEDC), to refund over 20,000 estimated billing customers following confirmed cases of wrongful billing.
This directive was issued through a public notice released on Monday, in which the Commission stated that the decision was based on numerous complaints received from MainPower customers regarding overbilling practices.
According to the notice, “Pursuant to Section 35 of the Enugu State Electricity Law 2023 and other extant rules, the Commission has issued an Order to MainPower to refund the affected customers the overbilled units for energy consumed in April 2025.”
The Commission announced that a list of the affected customers has been published on its official website, www.eerc.en.gov.ng/order. It also urged customers who do not receive a refund within the specified timeframe to contact EERC via email at info@eerc.en.gov.ng or call 09122642755.
The refund order, jointly signed by EERC Chairman Chijioke Okonkwo and Commissioner for Market Operations, Barr. Reuben Okoye, mandates MainPower to complete all refunds by the July 2025 billing cycle. Failure to comply will result in a fine of ₦500,000 for each day of default, in accordance with the Enugu State Electricity Law, 2023.
EERC noted that it began monitoring MainPower’s estimated billing practices after assuming regulatory control from the Nigerian Electricity Regulatory Commission (NERC) in October 2024. Concerns were first raised in a letter dated December 16, 2024, which MainPower failed to adequately address in their January 14, 2025 response.
Further warnings were issued in April and May 2025. EERC pointed out a suspicious similarity in estimated billing figures for February and March 2025, demanding a response within 14 days. That deadline expired on May 23 without a reply from MainPower.
Upon reviewing MainPower’s April 2025 billing report, the Commission found that estimated billing violations increased to 34 percent, up from 24 percent in the previous months.
EERC concluded that MainPower had deliberately breached the terms of its interim licence concerning the capping of estimated billing. As a result, MainPower is now required to refund the full amount of the April 2025 overbilling to the affected customers no later than July 2025.
