Nigeria’s electricity distribution companies billed customers ₦250.79 billion from ₦333.94 billion worth of energy received in July 2026 and collected ₦205.53 billion, regulatory data show, exposing the commercial gap that remains between electricity supplied to the distribution network, revenue billed and cash eventually recovered.
The Nigerian Electricity Regulatory Commission said the country’s distribution companies recorded a 75.10% billing efficiency during the month.
That means not all the value of energy received by the DisCos was converted into customer bills.
Of the ₦250.79 billion eventually billed, 81.95% was collected, leaving the sector with ₦205.53 billion in actual revenue collections for July.
NERC separately reported an industry recovery efficiency of 74.91%. That figure is a regulator-defined performance metric and should not be read as a simple calculation of cash collected divided by the reported value of energy received.
The figures give a clearer view of one of Nigeria’s longest-running electricity-sector challenges: getting power onto the system is only one part of the commercial equation.
The industry must also convert that energy into billed revenue and then collect the money due.
IDNN calculations show a ₦128.41bn gap from energy received to cash collected
Based on NERC’s published figures, IDNN calculates a ₦128.41 billion difference between the ₦333.94 billion value of energy received by the DisCos and the ₦205.53 billion actually collected in July.
That figure is an editorial calculation from the regulator’s data. It is not a NERC-described cash loss.
The gap occurred in two stages.
First, ₦83.15 billion separated the value of energy received from the amount eventually billed.
Second, ₦45.26 billion separated bills issued from cash collected.
These figures show that not all energy received was converted into billed revenue and that not all billed revenue was collected.
Identifying the precise causes of those gaps requires operator-level evidence beyond the national aggregate.
Eko leads recovery performance
NERC said Eko DisCo recorded the strongest recovery efficiency at 94.67% in July.
Port Harcourt followed at 84.95%, while Benin recorded 79.15%.
The wide differences between operators matter because Nigeria’s electricity market is not facing one uniform commercial problem.
DisCos operate across territories with different customer mixes, infrastructure conditions and payment environments.
That means national averages can conceal substantial variation in how effectively individual companies convert electricity received into billed and collected revenue.
For regulators, investors and consumers, the key question is therefore not only how much the sector collects nationally, but which operators consistently narrow the gap between energy received, revenue billed and cash recovered.
August generation data expose a separate operational constraint
The commercial picture sits alongside a separate operational challenge.
In its August 2026 performance data, NERC said Nigeria’s grid-connected power plants had an average available generation capacity of 4,758 megawatts during the month.
Average utilisation was 4,102 MW, representing an 86% load factor.
These are August operational figures and should not be combined directly with the July commercial data into a single performance ratio.
The available-capacity figure is itself significant because installed generation capacity is materially higher than the amount of capacity available for dispatch at any given time.
For example, NERC reported in April 2026 that Nigeria had 13,625 MW of installed generation capacity, while 4,286 MW was available for dispatch.
Those figures come from a different reporting period, but they illustrate the persistent distinction between installed capacity and generation that is actually available to the grid.
More revenue does not automatically mean more electricity
For consumers, rising sector revenue can be misleading when read in isolation.
Higher collections may reflect stronger billing, improved collection performance, tariff effects or changes in the volume and mix of electricity supplied.
They do not, by themselves, prove that households and businesses are receiving more hours of reliable power.
Likewise, stronger utilisation of available generation capacity does not necessarily mean supply has improved equally across distribution territories.
NERC’s reporting framework separately tracks generation, DisCo commercial performance, market remittances, consumer affairs and other indicators precisely because no single number captures the health of the electricity system.
The sector faces both commercial and operational constraints
July’s commercial data reduce one part of the power-sector challenge to a simple sequence.
The DisCos received energy valued at ₦333.94 billion.
They billed ₦250.79 billion.
They collected ₦205.53 billion.
Separately, August generation data show that the system used 4,102 MW out of 4,758 MW of average capacity available for dispatch.
These numbers describe different parts of the electricity market and different reporting periods.
Taken together, they highlight two persistent sector challenges: increasing dependable generation capacity available to the system and improving the conversion of electricity received into billed and collected revenue.
For consumers, the measure of success will not simply be whether DisCos collect more money.
It will be whether stronger commercial performance is matched by more reliable, measurable and accountable electricity supply.
