The UK could experience its first large-scale blackout in decades this winter if gas shortages combine with particularly cold weather. That’s according to the government’s “reasonable worst case scenario”, a warning which was dismissed by a No 10 spokesperson.
For blackouts to happen, many different factors would have to line up. The UK has control of some of these factors, such as the day-to-day running of the energy system or policies to try and reduce demand for gas and electricity at peak hours (the two are linked since about a third of the UK’s electricity is generated by burning natural gas).
