Power Minister Joseph Tegbe says the first affected generating units should return to service within 48 to 72 hours, following outages linked to maintenance and gas shortages.
Tegbe gave the forecast in a statement posted on his social media pages on Friday. He blamed planned maintenance at Egbin Power Station in Lagos and gas supply constraints at some thermal plants.
The reduced generation has left less electricity for homes and businesses, with grid operators cutting supply in some areas to manage the shortfall, the minister said.
He also said sabotage of transmission lines had restricted alternative supply routes, particularly to Lagos. His team was working with operators to improve gas supply and repair damaged infrastructure.
The Transmission Company of Nigeria (TCN), meanwhile, disputes Ikeja Electric’s explanation for outages on some Band A feeders. Ikeja Electric apologised for falling below the minimum daily supply requirement of 20 hours and attributed interruptions to grid instability.
TCN says reduced generation and the resulting allocations, rather than transmission equipment failure, explain the shortfall. It also attributes some interruptions to faults and maintenance on the distribution network.
The dispute follows NISO’s explanation of the generation shortfall on Thursday.
Tegbe promised further updates as supply is restored. His 48-to-72-hour forecast concerns the first generating units returning, not a deadline for full restoration.
