Nigeria suffered a widespread electricity blackout after its national grid collapsed on Wednesday, the country's power distribution companies said.

Nigeria's grid is prone to failure and has this year suffered partial or total collapse at least 10 times, mainly due to faults and vandalism at power installations.

Distribution companies across Nigeria, also known as Discos, said in separate statements that the grid had failed at around 1233 GMT and they hoped electricity would be restored soon.

Data from the Transmission Company of Nigeria showed electricity generation plunged from 3,087 megawatt before the grid collapse, to zero as of 1400 GMT.
