Port Harcourt — 28 grid-connected electricity generation plants across Nigeria generated an average of 5,237 megawatts, MW, of electricity in December 2024, reflecting a marginal decline of 1% from the 5,290MW recorded in November 2024.
Data on the operational performance of power plants released by the Nigerian Electricity Regulatory Commission, NERC, highlighted that the 28 plants achieved only a 38% availability factor despite their cumulative installed capacity of 13,625MW.
The report showed that larger power plants, including Egbin ST, Delta GS, Kainji, Shell’s Afam VI, Zungeru, Odukpani, Shiroro, Jebba, Okpai, Azura IPP, and Geregu, contributed 3,974MW on average—accounting for 75% of the total energy generated in December.
Egbin ST and Kainji emerged as the highest producers, with average outputs of 671MW and 505MW respectively, while Jebba followed with 454MW.
Smaller power plants such as Afam I-V, Sapele ST, Olorunsogo NIPP, Omotosho NIPP, Sapele GT NIPP, Ihovbor NIPP, Geregu NIPP, Omotosho, Olorunsogo, Ibom Power, Rivers NIPP, Omoku, Trans Amadi, Paras, Taopex Energy, Mepp, and Dadin Kowa generated a combined average of 1,261MW, representing 25% of the total energy output.
However, some plants performed below capacity. For instance, Ibom Power and Trans Amadi produced just 15MW and 3MW on average, while Alaoji NIPP failed to generate any power during the period, despite its installed capacity of 500MW.
NERC’s data also revealed that the average hourly available capacity from the 28 power plants was 4,524MWh/h during the review period, further underscoring the gap between installed capacity and actual performance in Nigeria’s power sector.
