The National Grid has issued a blackout warning amid concerns over increased power use in the cold weather. The unexpected alert said there was a potential for power cuts on Tuesday night at around 7pm.
It said there would be a "tight electricity margin" as people returned home from work, cooked their evening meals and used other electrical appliances. However the automated alert was later withdrawn as they said contingency plans had been set in place, reports the Daily Telegraph.
The warning was posted on the website of the electricity network operator then quickly removed. However, following its withdrawal experts said it showed signs that there were likely to be "much tighter days ahead".
The National Grid issues warnings when supplies are likely to be under pressure. This comes when insufficient power is being generated to supply the demand across the country.
Energy sector expert Phil Hewitt, director at Stockton-on-Tees-based Enappsys, said: "This is the first tight day of the winter but it is not super tight. It is a small appetizer of tightness, there will be much tighter days ahead."
The National Grid website says: "The notices are intended to be a signal that the risk of a System Stress Event in the GB electricity network is higher than under normal circumstances."
