Europe is experiencing its hottest spell since records began in 1947, with France setting new temperature highs. This extreme weather has forced some power plants to reduce output or shut down entirely.

The nuclear sector, which typically provides a stable supply of electricity, has seen disruptions. In particular, the Golfech plant in southern France had to close its doors when river temperatures rose above safe levels for cooling systems. Such measures are becoming more frequent as climate change intensifies.

Other forms of power generation are also struggling with the heat. Hydropower plants have seen a 13% decrease in production across Europe due to low water levels, while natural gas and coal plants report reduced efficiency. The demand for cooling is driving up electricity usage, putting pressure on grids that were not designed for such peaks.

While the current situation seems manageable, experts warn of future challenges. Climate change will likely lead to more frequent and severe heatwaves, potentially exacerbating these issues. Utilities may need to invest in climate-proofing their infrastructure, but at a significant cost.
