The Enugu State Electricity Regulatory Commission (EERC) has directed MainPower Electricity Distribution Company (formerly Enugu Electricity Distribution Company, EEDC) to refund over 20,000 customers for wrongful billing in April 2025.
In a public notice issued Monday, EERC cited persistent consumer complaints and said MainPower violated caps on estimated billing, breaching its licensing terms under the Enugu State Electricity Law, 2023.
“The Commission has issued an order to MainPower to refund the affected customers the overbilled units for energy consumed in April 2025,” the EERC stated.
A list of affected customers has been published on www.eerc.en.gov.ng/order. Customers not refunded by the end of the July 2025 billing cycle are encouraged to contact the Commission via info@eerc.en.gov.ng or call 09122642755.
EERC Chairman Chijioke Okonkwo and Commissioner Reuben Okoye signed the order, warning MainPower that failure to comply would result in a ₦500,000 daily fine beginning August 1, 2025.
Timeline of Violations:
October 2024: EERC assumes regulatory control from NERC and begins tracking estimated billing irregularities.
December 16, 2024: First letter sent to MainPower regarding billing issues.
January 14, 2025: MainPower responds inadequately.
April 4, 2025: EERC cites continued violations from Oct 2024 – Feb 2025.
May 6, 2025: EERC flags billing irregularities in Feb–Mar 2025 reports and gives 14 days for explanation.
May 23, 2025: Deadline lapses without response.
May 2025: EERC review finds overbilling violations rose to 34% in April, up from 24% in Feb/March.
Regulatory Findings:
EERC concluded that MainPower had deliberately violated billing caps, breaching terms of its interim licence. The Commission’s analysis of billing records showed repetitive and suspiciously similar estimated charges, prompting regulatory action.
“The Commission recently reviewed MainPower’s April 2025 estimated report, and observed that the degree of violation… had further deteriorated.”
Enforcement:
MainPower must fully refund the April 2025 overbills by the July billing cycle at the latest. Non-compliance will trigger a daily fine of ₦500,000, as provided under Section 32(5) of the 2023 electricity law.
This marks the first major enforcement action under Enugu’s new electricity regulatory regime since assuming full authority from NERC, and signals a stricter approach to consumer protection in the newly decentralised power sector.
