Households in Britain could face power cuts of up to three hours this winter if gas supplies become critically low, according to a warning from National Grid. The company described the scenario as “unlikely” but said it could occur if the energy crisis intensifies.
Under the worst-case scenario, cuts would likely happen at peak times, such as between 4pm and 7pm, and customers would be warned at least a day in advance. The disruptions would be rotated so that not all areas are affected simultaneously.
National Grid’s base case expects no problems for homes, but it has outlined two more worrying scenarios. The first involves Britain being unable to import electricity from France, Belgium or the Netherlands due to Europe’s energy crisis, though power would still flow from Norway. To mitigate this, National Grid has secured deals with EDF, Drax and Uniper to keep additional coal-fired power stations on standby.
From 1 November, a scheme will incentivise households and businesses to reduce electricity use at key times. Households with smart meters could be paid around £10 per day for cutting usage, such as avoiding washing machines or ovens. Larger businesses can be paid for shifting energy use or switching to batteries or generators during peak times.
Prime Minister Liz Truss, who previously pledged no energy rationing this winter, said on Thursday that the UK has a “good supply of energy” and is in a “much better position than many other countries.” However, reports suggest some in government want a public campaign to encourage energy saving, though a spokesperson for the Department for Business, Energy and Industrial Strategy denied this, stating: “Ministers are not launching a public information campaign.”
National Grid attributed the potential shortages to Russia’s invasion of Ukraine, which has caused “unprecedented turmoil and volatility” in energy markets. While the UK is less reliant on Russian gas than mainland Europe, it could still face knock-on effects from shortfalls on the continent. The last time such power cuts were used was in the 1970s, and they would require government and royal approval.
