Strong winds over the whole country pushed this up to a peak of 7% at one point during the night, when the power output reached 3885MW, according to data provided by the grid operator RTE.
"The turbines were operating at over 70% of their total power," says the Renewable Energy Syndicate (SER), a trade association. SER notes the electricity generated represents "nearly twice the average consumption of a city such as Paris."
Current installed capacity in mainland France stands at just over 5.1GW.
