Europe’s extreme heat is forcing power plants to shut down or limit output, putting a strain on the grid. Rising temperatures are affecting nuclear and natural-gas power plants, as well as hydropower and coal plants. The heat wave, which has seen temperatures soar to over 44°C in France, is causing water shortages that are impacting cooling systems. This heat wave is a reminder that the power sector is vulnerable to extreme weather events, and utilities must be prepared to adapt to changing conditions. Why it matters: This heat wave highlights the need for greater resilience in Europe’s power grid, particularly in the face of increasingly frequent and severe weather events.
