The whole of Lekki district in Lagos, Nigeria, was subject to a total blackout following a complete system collapse starting 15.09 hours on 28 April. The Lekki district, including Lagos Island, Ajah, Ibeju Lekki, and Ikoyi, is supplied by the Eko Electricity Distribution Company (EKEDC).
Godwin Idemudia, General Manager of Corporate Communications for EKEDC, said that the outage was due to a shortage of electricity supply from the National Grid. He said that the power supply shortage was due to a cut on the Egbin-Benin 330 kV line, resulting in the shutdown of Egbin plant and the curtailment of supply into Lagos. He said that the Transmission Company of Nigeria (TCN) was working to rectify the situation, and power supply would be restored back to normal as soon as possible.
On 26 April, TCN announced that the national grid was experiencing reduced power generation, due to emergency maintenance by Nigeria Gas Company on its gas pipelines supplying gas to Egbin, Omotosho, Olorunsogo, and Paras power stations. This was reportedly caused by leakage discovered on the Escravos-Lagos Pipeline System gas pipeline.
