Hinkley Point C is a first of its kind project, if you want to be economical you should look to KNGR
https://en.m.wikipedia.org/wiki/APR-140 they've built several in Korea and one in Saudi Arabia where the cost was $24.4 billion for 5380 MW.
it's cute that you are mentioning onshore wind but that will just never happen, takes up way too much space and most places have a capacity factor of below 20% making your 34500 Mw 6900Mw as well as giving you erratic output. so for wind to work you either need fossil fuels, power 2x or some new magical battery that will make the cost of such a solution insane because you'd have to completely overhaul your infrastructure.
offshore wind is more realistic, but costs way more than nuclear.
wind makes sense of you want to built something fast, but it won't bring down your carbon footprint. og at least it haven't in Germany or Denmark. the only reduction we've seen is because we burn trash and biomass which fair some messed up reason is considered green and renewable.
