A major fault at the Egbin Power Plc, combined with a transmission line failure on the Osogbo–Ikeja West 330kV network, has sparked fears of prolonged electricity shortages across Lagos and nearby areas.
According to the Nigerian Independent System Operator, a sudden closure of the Egbin Power Station and a concurrent transmission line failure may result in a protracted blackout in Lagos State.
A significant operational disruption at the Egbin Power Station resulted in a total loss of generation and severe supply limitations in the country's commercial center, the system operator said in a statement on Thursday.
Although the corporation has not yet confirmed the cause or provided an official explanation of what happened, the development has also fueled rumors of an event that allegedly resulted in the death of a contractor.
According to the system operator's statement, the plant's production fell from roughly 641 megawatts to zero at approximately 8:21 p.m. on April 28.
The plant's crucial equipment failure was blamed for the stoppage.
"The Nigerian Independent System Operator wishes to inform the general public of a significant reduction in power generation currently affecting electricity supply across the country, particularly within the Lagos region," the notification said in part.
"A significant operational disruption occurred at Egbin Power Station, the biggest electricity-generating facility on the national grid and a significant contributor to Nigeria's daily power supply.
On April 28, 2026, at around 8:21 p.m., Egbin Power Station recorded a complete loss of generating, going from roughly 641MW to zero output.
"This incident was caused by a circulating water pump system malfunction and the plant's central compressor failing, which required an immediate shutdown of all generating units to safeguard the facility."
The operator clarified that a transmission limitation that affected power delivery into Lagos exacerbated the effects of the generation loss.
"The forced outage of the Osogbo–Ikeja West 330kV transmission line is currently further restricting the power supply to the Lagos region, thereby limiting the evacuation of available generation into the Lagos load center," the statement continued.
The system operator claims that the twofold disruption has resulted in a large supply gap, necessitating the rationing of electricity by authorities to avoid a complete collapse of the system.
The statement went on, "As a result, this loss of generation has created a significant supply shortfall, necessitating immediate load-shedding measures to maintain grid stability and prevent a wider system disturbance."
According to the agency, emergency procedures have been put in place to control the situation and lessen its effects on customers.
Since then, system operators have implemented backup plans, such as redistributing available load across distribution firms while giving priority to vital national infrastructure.
It added, "To lessen the impact of this development on electricity consumers, efforts are ongoing to optimize generation from other available power plants."
The operator expressed regret to customers, especially in Lagos and surrounding areas where disruptions have been more noticeable.
"We acknowledge the inconvenience this situation has caused electricity consumers, particularly in Lagos and surrounding areas, and we assure the public that all relevant stakeholders are working closely to resolve the situation as quickly as possible," the statement continued.
With an installed capacity of approximately 1,300MW, the Egbin Power Station in Ikorodu, Lagos, is the biggest thermal power plant on Nigeria's national grid; however, actual generation varies because of maintenance, gas supply, and grid limitations.
Because of its crucial function, any big outage frequently has a quick and extensive effect on the supply of energy, especially in Lagos, which contributes significantly to the country's power consumption.
Another vital component for power evacuation into Lagos is the Osogbo–Ikeja West 330kV transmission line, which connects the state's distribution network to generation sources located around the nation.
The most recent disruption demonstrates the vulnerability of Nigeria's electrical grid, where cascading supply shortages can be caused by single-point failures in transmission or generation equipment.
Long-term fixes include increasing transmission capacity, diversifying generation sources, and enhancing the upkeep of vital infrastructure, even though temporary fixes like load shedding aid in system stabilization.
