National Energy System Operator calls for extra generation amid record demand from cooling devices during Britain’s third summer heatwave.
Britain’s National Energy System Operator (Neso) issued a rare overnight notice urging energy companies to boost power generation for Thursday night. The alert follows surging demand from fans and air conditioners during the country’s third heatwave of the summer, risking supply shortages.
This marks Neso’s second warning in two months, highlighting growing strain on the grid from extreme temperatures. Previous heatwaves have also triggered elevated demand, but this week’s record usage underscores the system’s vulnerability to climate-driven spikes.
No immediate market reaction was reported, though prolonged strain could pressure energy prices and infrastructure resilience.
