The Nigeria Electricity Supply Industry (NESI) has suffered a cumulative revenue loss of ₦200.495 billion across all DisCos arising from Aggregate Technical, Commercial and Collection (ATC&C) Losses, according to 2025 first quarter report (2025 Q1) released by the Nigerian Electricity Regulatory Commission (NERC).
Distribution Companies (DisCos) recorded a decreased revenue collection efficiency amounting to N190. 64 billion in the first quarter of 2025 (Q1 2025) achieving only N553.63 billion out of ₦744.27 billion billed to customers.
This translates to a collection efficiency of 74.39%, representing a decrease of 3.05p compared to 2024/Q4 (77.44%) record.
Also, although the total energy received by all DisCos in 2025/Q1 was 8,169.00GWh, the energy billed to end-use customers was only 6,631.92GWh, translating into an overall billing efficiency of 81.18% which represents a 2.48 percent decrease relative to the 83.66% billing efficiency recorded in 2024/Q4.
Further statistics showed however that the DisCos recorded increased energy offtake performance in Q1 2025 than in Q4 2024.
Accordingly, “In 2025/Q1, the average energy offtake by DisCos at their trading points was 3,781.94MWh/h which represents an increase of 421.17MWh/h (+12.53%) compared to the average offtake recorded in 2024/Q4 (3,360.77MWh/h). Cumulatively, DisCos recorded an overall offtake performance of 97.94% – the available Partially Contracted Capacity (PCC) during the quarter was 3,861.53MWh/h.”
In terms of Aggregate Technical, Commercial and Collection (ATC&C) Loss, the weighted average ATC&C loss across all the DisCo in 2025/Q1
was 39.61%, comprising technical and commercial loss (18.82%) and
collection loss (25.61%).
“The ATC&C loss of 39.61% is 19.07 percent higher than the 2025 MYTO target (20.54%) and translates to a cumulative revenue loss of ₦200.495 billion across all DisCos.
“The ATC&C loss increased by 4.39pp (worse performance) compared to 2024/Q4 (35.22%). All the DisCos failed to achieve their target ATC&C during the quarter, with Kaduna DisCo recording the worst underperformance relative to the target ATC&C (Actual – 68.57% vs. target – 21.32%)”, the report revealed.
For this quarter, the report attributed increase in energy generation during the quarter to the increase in available generation capacity as well as the increase in energy offtake by the grid-connected customers (including DisCos) compared to 2024/Q4.
The average available generation capacity of the grid connected power plants increased by 69.99MW (+1.32%) from the 5,296.89MW recorded in 2024/Q4 to 5,366.88MW in 2025/Q1.
The average hourly generation on the grid in 2025/Q1 was 4,770.59MWh/h, which translates to a total generation of 10,304.47GWh. However, the average hourly generation of the grid-connected power plants increased by 563.18MWh/h (+13.39%) from 4,207.41MWh/h in 2024/Q4.
The total electricity generated in
the quarter also increased by 1,014.52GWh (+10.92%)4 from 9,289.95GWh in 2024/Q4 .
In respect of complaints in previous quarters on metering, billing and service interruption by customers, the number of complaints received across all DisCo-CCUs was 254,404, which represents a 7.72% decrease compared to the 275,681 received in 2024/Q4.
