Australia used to hit the market "cap" of $15,000 per MWh a few times a year:

Not as sustained but the ongoing gaming by the generators (to avoid selling power at the marginal cost + fixed % markup) resulted in the wholesale market being capped down to a 300 $/MWh. But thats only achievable here because so much of the grid is vertically integrated power plants physically on top of coal mines, yet they want to "sell" the coal at international market prices when it suits them. UK being reliant on importing energy is going to hurt.

Almost half (26 out of 56) of our nuclear plants were halted a few weeks ago. A few have been restarted since then, but there's still a significant fraction that is halted. You bet we are maxed out.

Ouch. What was/is the common cause? Fractures?
Looking at the yearly UK-Franch interconnectors graph on gridwatch, I would have guessed more than a few weeks. More like starting in April/May/June.

It's a combination of multiple factors, which, to be fair, would require a pretty long and detailed explanation. Otherwise the short version may look too much like a conspiracy theory.
One of the factors was that they were under maintenance, but how come that many plants could end up under maintenance at the same time, that's complicated (and sounds unbelievable.)
I have not heard of any particular incident. I think it's relatively standard maintenance, now sure some of our plants are getting a bit old, so maintenance is required and sometimes longish.
The management of our energy company EDF has also been largely questionable for over a decade.
But all in all, we have been sabotaging our energy production capabilities in most of Europe. There's absolutely nothing unexpected here.
Apparently all is well as we're going to build "green" hydrogen pipelines. Yes, really. https://www.reuters.com/business/energy/h2med-hydrogen-pipeline-france-cost-25-bln-euros-spanish-pm-sanchez-says-2022-12-09/

Read yesterday in the Guardian I think it was that wind power was down to under 3.6% here in the UK, of course being the Guardian it was all down to global warming that there was no wind. Thing is here in the UK we have always had foggy days that go on for a few days or even a week and when there is fog there is no wind, guess these city idiots just don't realise this and think the wind is a steady state thing.
