Britain faces a precarious energy situation this winter, with experts warning that the country's reliance on imported electricity and a rapid shift to renewables have created a significant vulnerability.
Energy consultant Kathryn Porter told The Mail on Sunday that the nation's pursuit of Net Zero, coupled with power station closures and an increased reliance on wind and solar power, means Britain may struggle to meet its own demand, particularly during periods of low wind.
"We've put ourselves in a position where we can't meet our own demand, particularly when the wind doesn't blow," Porter stated. "We can cope with these risks individually, but combined they are a threat. It means we have to be lucky all the time."
This warning comes as Ofgem announced an increase in the energy price cap by £60 to £1,723 per year in October, with experts predicting further surges in household bills.
European nations are also bracing for energy shocks due to the war in Iran, low gas reserves, and drought in Norway impacting hydroelectric power exports. However, Porter argues that Britain is uniquely exposed due to its energy infrastructure and policy choices.
Shadow energy minister Andrew Bowie echoed these concerns, calling the looming electricity shortage "increasingly dangerous" and urging the government to reconsider domestic resource exploitation. He suggested that the Jackdaw gas field in the North Sea, if operational, could provide gas by Christmas. However, a decision on its development has reportedly been postponed.
A National Audit Office report highlighted that delays in upgrading the national grid will cost consumers billions. The report estimates that efforts to decarbonize the grid by 2030 could add £1.9 billion annually to bills, as the current transmission system struggles to accommodate the shift to renewables.
Further complicating the situation, neighboring countries might prioritize their domestic energy needs, potentially restricting exports. Norwegian politicians have already voiced concerns about their nation being treated as "Europe's battery."
"There's a danger governments will prioritise their own consumers," Porter said. "They will stop exporting any spare capacity and the market will break down."
Record low reservoir levels due to heatwaves exacerbate the problem, impacting hydroelectric power. Britain's aging electricity infrastructure, combined with the unpredictability of wind and solar energy, adds to the strain. Whistleblowers from the National Energy System Operator (Neso) have previously claimed the grid has operated at times outside safety limits due to electricity shortages, with one engineer reportedly stating that power cuts are now a "mathematical certainty."
Porter warned that a prolonged period of high pressure with no wind, similar to that experienced in the summer, could place Britain in an "extraordinarily difficult position." She added that the failure of a single large power station or interconnector could be enough to cause grid failure.
"You don't have to have too many things go against you for the grid to break down," she concluded. "Who, in the cold light of day, could honestly say this is a sensible way to run things?"
