Electricity Distribution Companies failed to bill ₦76.08 billion worth of energy in May 2026, the Nigerian Electricity Regulatory Commission has revealed.
According to NERC’s Commercial Performance Factsheet, power distribution companies received electricity worth ₦328.95 billion, but only billed customers ₦252.87 billion
The Commission said billing efficiency therefore dropped to 76.87%, down 6.45 percentage points from April.
Besides, DiscCos collected ₦208.15 billion out of ₦252.87 billion billed pushing pushed collection efficiency up to 82.32%.
The companies ranked ₦96.16 for every kWh against an allowed rate of ₦124.39/kWh. Recovery efficiency declined to 77.31% during the period, the Commission said.
Ikeja Electric topped the recovery efficiency chart at 94.63%, followed by Eko Disco at 91.54% and Abuja Disco at 84.84%. Port Harcourt Disco also posted a strong recovery efficiency of 81.46%.
At the other end, Kaduna, Jos and Kano had the weakest recovery.
Kaduna recorded 39.75%, Jos 45.38% and Kano 49.80%.
All three, however, showed small improvements from April.
Eko Disco led the pack at 90.66% on billing efficiency, while Ikeja followed at 82.86% and Port Harcourt at 80.15%.
Ibadan DisCco had the steepest decline in billing efficiency, falling by 23.24 percentage points to close the month at 65.30%, alongside Enugu Disco, which dropped 19.51 percentage points to 73.26%.
Benin Disco maintained the highest jump in collection efficiency, rising 6.73 percentage points to 88.79%, while Eko followed with an 8.89-point gain to 85.37%.
Under NERC’s colour-coded ranking, Kaduna, Jos, Kano and Enugu were in the red zone for May.
The regulator marks DisCos below 50% recovery as red, 50% to 79% as amber, and 80% and above as green.
The development shows the gap between Nigeria’s best and worst DisCos is widening.
It further noted that the figures reflect month-on-month percentage changes compared to April 2026 data.
