Power distribution companies (Discos) are still falling short when billing customers despite receiving more electricity for distribution, according to the latest report released by the Nigerian Electricity Regulatory Commission (NERC).
An analysis by Business Post on the May 2025 factsheet shows that while Discos received 2,774.49 GWh of electricity, which translates to a 5.80 per cent increase compared to April, and billed out 2,255.51 GWh, billing efficiency dropped by 2.01 percentage points, settling at 81.29 per cent.
This means nearly 19 per cent of the electricity distributed to consumers remains unbilled, compounding the financial woes in the power sector.
Billing efficiency reflects the ratio of energy billed to the total energy received by Discos. The decline indicates that a significant portion of the energy supplied is either not recorded, lost, or distributed to customers without proper metering, all of which contribute to revenue loss.
The data from NERC during the review month also showed that out of the N261.82 billion billed to customers in May, only N191.57 billion was collected. This reflects a collection efficiency of 73.17 per cent, down by 4.42 per cent from April.
In terms of revenue recovery, Discos were allowed to collect an average of N116.25/kWh, but they managed to recover only N82.05/kWh, pushing recovery efficiency down to 70.58 per cent, a 7.32 per cent drop from the previous month.
On the billing front, Benin, Ikeja, and Eko Discos led the pack, maintaining high billing efficiencies of 88.73 per cent 87.44 per cent, and 87.62 per cent, respectively.
The factsheet showed that Eko Disco also recorded one of the highest improvements in collection performance, suggesting a solid overall commercial strategy.
On the other end, Yola Disco fared the worst, with a billing efficiency of just 63.45 per cent, and a collection efficiency of 50.59 per cent. Jos and Kaduna Discos also reported worrying figures, showing deep cracks in their billing and revenue structures.
An improvement in Nigeria’s billing and collection efficiency could help mitigate challenges amid efforts to increase power generation and supply.
