Energy secretary Ed Davey has insisted there is no threat to electricity supplies from the huge blaze at a power station in Oxfordshire.
RWE is expected to make a statement this morning on the inferno at its Didcot B plant last night.
Davey said: “I’ve been reassured by National Grid that there is no risk to electricity supplies.
“I will be keeping in touch with the relevant authorities throughout. My priority is to understand the cause of the fire and get the affected unit back generating electricity as soon as it’s safe to do so.”
Oxfordshire County Council Fire and Rescue Service said the fire began in a colling tower and spread to three others in windy conditions.
The fire service said it was called to the power station just after 8pm last night and took two hours to get the blaze under control.
A dampening down operation was continuing this morning, with three fire engines at the scene.
A smoke plume affected the local neighbourhood areas and residents were instructed to stay indoors and to shut all windows. No injuries have been reported.
Fire chiefs will work with Thames Valley Police to investigate the cause of the blaze.
