Unit two on the Golfech nuclear energy plant in southern France shut down at about 11:45 p.m. on June 22 when the river used to chill the plant obtained too scorching. The transfer was a precautionary measure, in keeping with Brid Nelligan, a spokesperson for EDF, the plant’s proprietor and operator.
The ability plant takes in water from the Garonne River after which returns most of it to the river at barely greater temperatures after utilizing it to chill tools. French laws restrict the temperature of that return stream, so the nice and cozy water (it was anticipated to succeed in 28 °C, or round 82 °F) compelled the operator to close down the plant.
EDF, which operates France’s complete nuclear fleet, can also be limiting the output of different reactors throughout the nation—one reactor on the Nogent-sur-Seine energy plant was ramped down as of Tuesday, and extra will observe later within the week, Nelligan says.
Excessive warmth has affected France’s nuclear trade earlier than. At the least seven gigawatts’ price of nuclear vitality was compelled to close down throughout the nation throughout a warmth wave in July 2025, in keeping with information from Ember Power. That’s greater than your complete grid of Eire.
This time, energy plant outages and limitations aren’t anticipated to be drastic sufficient to have an effect on the power to satisfy demand in France, in keeping with RTE, operator of the nationwide electrical grid.
Nuclear energy has made many of the headlines throughout this warmth wave, however different types of electrical energy era face comparable challenges. Hydropower crops incessantly run into issues when dry circumstances decrease the quantity of water obtainable to generate vitality and drive them to lower or shut off operations. Within the first 5 months of 2025, excessive temperatures and low water circumstances minimize hydropower provides in Europe by 13% in contrast with the 12 months earlier than.
