The failures of two generators are to be blamed for the mass power cuts across the UK on Friday, according to National Grid, the Electricity System Operator in Great Britain.
As a result, nearly 1,000,000 people were affected across large areas of the country.
Some 300,000 people were hit across London and southeastern part of the country, while 500,000 were hit across Western Power Distribution’s network.
A statement by National Grid on Friday night said the issue had been resolved, though train services across the country were widely disrupted, with carriages being stranded in some areas.
Meanwhile, a British government spokesman also said the issue was “now resolved”.
Train services to and from London were particularly badly hit, with many being told to avoid travelling until Saturday.
Some operators said full services to and from the capital would be cancelled for Friday night.
