Electricity supply across Lagos State has suffered a major setback following the shutdown of the Egbin Power Station and a separate fault on a critical transmission line feeding the state.
The Nigerian Independent System Operator confirmed the development on Thursday, warning that the twin incidents could trigger sustained power shortages in Lagos, the country’s highest electricity-consuming region.
The disruption reportedly began on April 28 when Egbin Power Station experienced a serious technical failure that forced a complete shutdown of its generating units. Power output plunged from about 641 megawatts to zero in a short time.
According to the operator, the shutdown was caused by a failure of the plant’s central compressor system, alongside a malfunction in its circulating water pump system. For safety reasons, all generating units were immediately taken offline.
“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.
“At approximately 8:21 p.m. on April 28, 2026, Egbin Power Station recorded a total loss of generation, dropping from about 641MW to zero output.
“This incident was caused by the failure of the plant’s central compressor, in addition to a malfunction of the circulating water pump system, which necessitated an immediate shutdown of all generating units to safeguard the facility.”
The situation was further worsened by a fault on the Osogbo–Ikeja West 330kV transmission line, a key corridor responsible for evacuating power into Lagos. The combined failures have significantly strained electricity distribution and raised concerns over possible extended outages in the state.
