Overbilling: EERC Orders Refund To Over 20,000 Customers

Exercising its regulatory authority, the Enugu State Electricity Regulatory Commission (EERC) has directed MainPower Electricity Distribution Company—formerly known as Enugu Electricity Distribution Company (EEDC)—to refund more than 20,000 customers who were inaccurately billed under estimated charges.

This was contained in a public notice issued by EERC on Monday where the commission said that its order was consequent upon many complaints by MainPower’s customers against the firm’s overbilling.

It said the list of the affected customers  have been published on the Commission’s website and advised affected customers of MainPower, who are not refunded at the expiration of the timeframe for the refund to contact the Commission for necessary action.

Meanwhile, the order signed by the Chairman of EERC, Chijioke Okonkwo, and the Commissioner in charge of Market Operations, Barr.
