France Shuts Down Three Nuclear Power Plants Due to Heatwave

Paris – 25.06.2026: As a result of the ongoing heatwave in France, the state electricity company EDF has shut down three nuclear power plants. The affected facilities are located in Golfech (Département Tarn-et-Garonne), Bugey (Département Ain), and Nogent-sur-Seine (Département Aube). This measure was taken to prevent the overheating of the rivers from which the plants draw their cooling water.

The rising water temperatures in the Garonne, Rhône, and Seine rivers led to a reduction in the reactors’ cooling performance. To avoid ecological damage caused by discharging water that is too warm, EDF decided to temporarily shut down the affected reactors. This decision concerns a total of three reactors at the mentioned nuclear power plants.

Despite the temporary shutdowns, EDF emphasized that the impact on the national electricity production is minimal. In recent years, shutting down nuclear power plants during heatwaves has led to an average annual reduction in electricity production of about 0.3 percent. However, more frequent and intense heatwaves could increase the impact on power supply.

The current heatwave in France is particularly intense and early. By mid-June, temperatures of up to 40 degrees Celsius were expected in some regions. These extreme conditions challenge not only the energy supply but also the environment and public health.

Given the rising temperatures and the associated risks for energy infrastructure, experts are calling on those responsible to increase investments in adapting the energy supply to climate change. This includes, among other things, improving cooling technologies in power plants and promoting renewable energy sources, which are less vulnerable to climate-related fluctuations.

French authorities have already taken measures to protect the population from the health effects of the heatwave. These measures include information campaigns, adjusting working hours, and providing emergency shelters for particularly vulnerable individuals. Nevertheless, the situation remains tense, and further actions may be necessary to address the challenges of the current heatwave.

Overall, the current situation highlights the vulnerability of French energy infrastructure to extreme weather events. It remains to be seen how the situation will develop in the coming days and what further steps will be taken to ensure the country’s energy supply.

The French government is under pressure to develop long-term strategies to make the energy supply more resilient in the face of climate change. This also includes the increased integration of renewable energies and improving energy efficiency across all sectors.

In conclusion, the current heatwave in France not only poses a challenge for the energy supply but also for society as a whole. It is therefore crucial that both the government and the population work together on solutions to effectively confront the impacts of climate change.
