Yes, I have some numbers. Wholesale electricity costs since 2020 have repeatedly exceeded 700 - SEVEN HUNDRED - Euros per MWh (1). Because it was dark and still, a condition every single European in the last ten thousand years has known to exist. That's your number.

I won't ask you what impact you think that has on, say, steelmaking, because I've lived it. I've picked the tenders and the Euro steel was not competitive with Chinese steel if it was free, due to uncertainty in delivery date.

China spent approx 2x Hinkley Point on nuclear. It has 30 GW of capacity in return. That works in winter. I would do nasty things to get that for my country.

(1) Naturally, French nuclear is literally not allowed to access this price, and must sell at 45. Because FREE MARKET.
