As I demonstrated in my comment, Hinkley Point C, even with its massive cost overruns (and true, nobody knows if that's the final cost yet, but that's the current figure), is roughly on par with offshore wind in cost per installed GW after accounting for capacity factors. It's just that Hickley Point C will have as much capacity as the entire north sea offshore wind fleet (all countries, not just UK), and so the concentrated single number gets very big. And wind is massively subsidised, too, so the subsidy is not an argument in itself.
