If the flaw with nuclear is that private investors won't bite unless there's a very predictable return (£90/MWh, apparently), the flaw with wind is that private investors won't cover the (at least one) order of magnitude of excess capacity needed to meet a cold snap. Having to pay wind producers to power off seems like we've combined the operational flaws of both - admittedly, at a much lower price point and without the waste/accident issues.
