Weather tracker: Unusually warm rivers affect French nuclear power plants

Unusually warm rivers across western and central Europe are adding pressure to energy infrastructure, especially France’s nuclear sector. High temperatures and low rainfall have reduced river levels and raised water temperatures, forcing EDF to temporarily shut a reactor at Golfech when the Garonne neared environmental discharge limits. Production restrictions are also expected at Nogent if temperatures rise further. The situation underscores how heatwaves can constrain power generation just as electricity demand rises from air-conditioning use. The article also notes broader climate impacts: elevated wildfire risk in Spain and continued flood risk from Typhoon Bavi in China. For markets, the key takeaway is potential short-term supply pressure in French power generation and possible support for European electricity prices if warm, dry conditions persist.
