National Grid boss John Pettigrew has outlined the 'worst case scenario' which could see three-hour blackouts from as soon as January if gas stocks get low this winter.
Pettigrew, who serves as the chief executive of the National Grid, was speaking at the Financial Times' Energy Transition Summit on Monday when he made the grave prediction, although he remained confident that the scheduled blackouts will not be needed.
The grim reading depends on a number of factors including on whether the UK fail to secure enough gas from Europe in time for the new year, especially if the country experiences a colder winter than expected.
