Source [3] seems highly suspicious. There's ~24 GW of wind capacity in the UK, the vast majority offshore, and according to Elexon Portal (https://www.elexonportal.co.uk https://www.elexonportal.co.uk, a good public frontend at http://gridwatch.org.uk/ http://gridwatch.org.uk/), which gives realtime grid data, the maximum production was 10.

That's not a success and, for the literal trillions of ESG money spent, someone should be held accountable for that.
