Nigerian grid instability leads to zero output from three plants

In September, three power plants in Nigeria (Alaoji_1, Ibom Power_1, and Rivers_1) generated no electricity, as reported by the Nigerian Electricity Regulatory Commission. These plants recorded zero megawatts in average hourly generation and a load factor of zero percent.

The national grid's average available capacity was 5,038 megawatts, while average hourly generation was 4,089 megawatts, resulting in a system-wide load factor of 81 percent. Compared to August 2026, available capacity increased by 5.89 percent, but average hourly generation declined by 0.30 percent, and the load factor fell by 5.04 percent.

Some plants operated at low levels, with Afam_1 generating 0.72 megawatts from an available capacity of 1.33 megawatts, and Geregu_2 producing 1 megawatt from 2 megawatts available. The national grid also operated outside prescribed frequency limits, with the average lower frequency at 49.43Hz and the upper frequency at 50.69Hz.

Voltage performance remained outside limits, indicating ongoing instability in the grid.
