@ExtinctionR In fact, if I'm reading the data correctly, it seems they phased out that last 500 GWh, compared to the winter of 2024-25, by importing that amount from the UK.
The UK did see an increase of 3 TWh last year for wind and 5 TWh for solar, but still had to import itself from nuclear France in the order of 30 TWh for 2025.
I can't pinpoint this closure, which is mostly symbolic at this point, to a rise in wind. Meanwhile, their fossil gas use didn't change much at all and still amounted to almost 15 TWh in 2025, half of the total electricity consumption.
