Nigeria's power plants operate at 31% capacity as grid instability worsens
Nigeria's grid-connected power plants operated at just 31% of installed capacity in April 2026, with only 4,286MW available out of 13,625MW total capacity, according to NERC's latest operational performance factsheet. While available generation improved slightly by 5% from March, persistent voltage and frequency instability continued to undermine grid reliability.
The monthly average lower grid voltage was 302.60kV (below the 313.50kV prescribed minimum) and upper voltage reached 353.40kV (above the 346.50kV maximum). Similarly, system frequency dropped to 49.20Hz (below the 49.75Hz minimum) and rose to 50.76Hz (above the 50.25Hz maximum). These persistent breaches of operational limits raise serious concerns about electricity quality and supply reliability for consumers and industrial users.
NERC reported that the top 10 energy-producing plants accounted for 81% of total electricity generated, with hydropower and major gas-fired plants dominating. Egbin emerged as the largest contributor at 557MW available from 1,320MW installed capacity. Meanwhile, several plants severely underperformed: Olorunsogo 2 had only 4% availability (33MW from 750MW installed), Afam 1 at 8%, and Sapele Steam 1 at just 1%. The data shows Nigeria continues to rely heavily on a small cluster of high-performing plants, leaving the grid vulnerable to disruptions.
Given that grid-connected plants are utilizing only a fraction of their capacity while struggling with basic stability, what alternative power solutions have you found most reliable for your home or business during these frequent outages?
