Electricite de France SA warned that unusually warm river temperatures are likely to force it to reduce nuclear output at time when about half the country’s reactors are already offline.

With air temperatures in Paris forecast to climb above 25 degrees celsius (77 Fahrenheit) this weekend, some of the rivers used to cool EDF’s nuclear power plants are set to get too warm to ensure normal output and production may have to be cut, the utility said Tuesday. Nuclear output is already down with 27 of the nation’s 56 reactors halted for repairs or maintenance.
