That £59.90 figure is 2012 prices.

In 2024 money offshore was £102 offshore, onshore £89. AR7 estimates are >10% higher. Those prices were not high enough for Hornsea 4, who cancelled the contract (with a big write down for the entire project) after being awarded it.

Hinkley C is, as everyone knows, a disaster.

Yes, like I said, UK CfD strike prices (both nuclear and wind) are always quoted in 2012 prices.

But even adjusting for inflation, offshore wind's £59.90 is a fraction of the retail price that UK consumers and most businesses pay for electricity. There's plenty of margin left for the middlemen (regulator, grid operator, distribution network operator, electricity retailer, etc).

... and Hinkley Point C's £92.50 is £133.79 today, and could be £160+ by the time it actually starts generating in (maybe?) 2031.
