UK grid operator warns of tight power supplies during heatwave
6 reported
Great Britain’s energy system operator has warned that extreme temperatures could affect power supplies on Thursday night, as the UK enters its third heatwave of the year. The National Energy System Operator (Neso) issued a notice overnight requesting extra supplies from power generators to meet increased demand from households using fans and air conditioners. This follows a similar plea last month during a heatwave that saw a provisional high of 37.7C at Lingwood in Norfolk on June 27, breaking the previous June record of 35.6C set in 1976. Parts of southern England are expected to reach 34C on Thursday, with the hot weather lasting over 10 days. Neso stated that tight electricity margins are forecast for Thursday evening due to extreme temperatures across Europe reducing generation availability. The government-owned body described the notice as a routine balancing tool and said there is no risk to customer electricity supplies. Across the Channel, French utility EDF warned that the heatwave is straining its nuclear reactors, which export power to the UK, and output could be curbed at up to five plants.
