The Nigerian Electricity Regulatory Commission (NERC) has disclosed that electricity distribution companies (DisCos) collected N205.53bn of the N250.79bn billed to customers in July 2026.
According to the Commission, this represents an 81.95 per cent collection efficiency.
It also disclosed that power plants connected to the national grid generated an average of 4,102 megawatts (MW) of electricity per hour in August, representing 86 per cent utilisation of the average available generation capacity of 4,758MW.
The figures were contained in NERC’s July 2026 Commercial Performance of Distribution Companies and August 2026 Operational Performance of Power Plants fact sheets.
According to the July commercial performance report, the DisCos received a total of 333.94 billion kilowatt-hours (kWh) of energy and billed 250.79 billion kWh, representing a billing efficiency of 75.10 per cent.
Of the N250.79bn total electricity billings, the companies collected N205.53bn, leaving a collection gap of N45.26bn.
NERC put the sector’s revenue recovery efficiency at 74.91 per cent, based on an allowed average tariff of N130.15/kWh against an actual average collection of N97.50/kWh.
Among the 11 DisCos, Eko recorded the highest collection efficiency at 101.78 per cent, followed by Benin at 89 per cent and Ikeja at 87.85 per cent.
It added that Abuja recorded 81.03 per cent, while Ibadan and Port Harcourt recorded 85.97 per cent and 84.69 per cent respectively.
On revenue recovery, NERC disclosed that Eko recorded the highest efficiency at 94.67 per cent, followed by Port Harcourt at 84.95 per cent.
It stated that the Benin DisCo recorded 79.15 per cent, Yola 78.24 per cent, Abuja 76.72 per cent and Ikeja 76.60 per cent.
However, it listed the Jos DisCo as having recorded the lowest revenue recovery efficiency at 46.27 per cent, followed by Kaduna at 39.71 per cent.
On the generation side, NERC’s August operational report showed that the average available capacity of grid-connected power plants stood at 4,758MW, while average hourly generation was 4,102MW.
The report said this represented an average load factor of 86 per cent, indicating that most of the available generation capacity was utilised during the month.
Among the top energy producers, Kainji recorded a 98 per cent load factor, generating an average 345MW out of 352MW available capacity. Afam 2 recorded 99 per cent, while Egbin recorded 96 per cent and Ihovbor 2 recorded 92 per cent.
Other major plants included Shiroro, with an 87 per cent load factor from an average 381MW generation against 438MW available capacity; Jebba recorded 83 per cent, Delta 80 per cent, Okpai 87 per cent and Zungeru 72 per cent.
The commission, however, reported continued deviations in grid frequency and voltage during August.
During the month under review, the average lower grid frequency was recorded at 49.34Hz, while the average upper grid frequency stood at 50.67Hz, exceeding the prescribed range of 49.75Hz to 50.25Hz.
Also, the monthly average lower grid voltage was 302.29kV and the upper average was 349.68kV, both outside the prescribed range of 313.50kV to 346.50kV.
