National Grid is asking the UK power industry to provide more electricity later on Wednesday.
National Grid has issued a Notification of Inadequate System Margin (NISM) as a result of multiple energy plant breakdowns.
“This is part of our standard toolkit for balancing supply and demand,” the company said.
“It indicates that we would like our power held in reserve to be higher.”
An additional 500 megawatts is being requested for between 16.30 and 18.30 on Wednesday.
The company last issued a NISM in February 2012 and before that in 2009.
