Neso issued an electricity margin notice overnight for Thursday evening’s peak period, calling for additional generation after extreme temperatures across Europe tightened margins by reducing generator availability. The notice follows a similar plea during June’s record heatwave and comes as southern England expects 34C on Thursday with hot weather forecast to last over 10 days. EDF separately warned that up to five of its French nuclear plants may curb output in the coming days due to high river-water temperatures, threatening electricity exports to the UK and Germany.
