LAGOS — Electricity supply has been restored to key commercial and residential districts along the Lekki-Ajah corridor in Lagos following days of power outages caused by a series of system disruptions, Nigeria’s grid operator has announced.
The Transmission Company of Nigeria (TCN) confirmed that the critical 330-kilovolt (kV) Ajah–Lekki transmission line was reconnected to the national grid at 3:18 pm local time on Wednesday, 21 October.
The outage began on Monday afternoon when a system disturbance isolated the Ajah transmission substation, cutting off power lines connected to the Egbin power station—one of Nigeria’s primary electricity generating facilities. Engineers managed to restore the connection, but the line tripped again hours later following a technical fault. Subsequent repair efforts faced further delays when a circuit breaker at the Lekki substation suffered a mechanical failure known as pole discordance, preventing the final reconnection.
TCN said its engineering team had since resolved the issue and safely closed the breaker to normalize the supply. The disruption affected thousands of homes and businesses supplied by the Eko Electricity Distribution Company (EKEDC) across the rapidly growing Lekki peninsula, a major economic hub in Nigeria’s commercial capital.
In a statement, TCN management expressed regret over the downtime and thanked residents and businesses for their patience during the repairs.
