Six of Nigeria’s power plants have reportedly been shut down in recent months, reducing the nation’s generation capacity to around 4.6 GW and potentially jeopardizing its recent supply stability.  

According to a power generation report issued this week by state-owned utility the Transmission Company of Nigeria (TCN) and obtained by Nigerian newspaper The Guardian, only 16 of the country’s 25 power plants are currently operational.

Of these plants, The Guardian reported that the majority are running at part load.

The shutdowns of the six plants were reportedly due to gas shortages, scheduled or unscheduled maintenance and technical faults.  

Among the offline plants are the 624 MW gas-fired Afam IV-V, which contributes 15-20 per cent of Nigeria’s total power supply; the 270 MW barge-mounted simple cycle AES plant; the 265 MW gas-fired Omoku II; and the 136 MW gas-fired Trans Amadi plant.

The 1320 MW Egbin power station (pictured), Nigeria’s largest thermal power plant, has seen its capacity reduced to 693 MW with the shutdown of its first unit for maintenance.

Other plants have also shut down or had their generation capacity reduced due to technical faults (including fires and a collapsed transmission tower) and, most commonly, lack of gas supply.

Nigeria’s current power shortfall has been estimated at around 9.9 GW. Sam Amadi, chair of Nigeria’s electricity regulator, has said the country’s power generation will reach 6 GW by the end of this year. The situation has improved since May, when Nigeria had just five functioning power plants.
