There have been serious cost reductions in the last few years in the offshore wind market. I assume you are aware of that?
Nope. Can't say I've noticed any of those reflected in my electricity bills. Those just keep going up, and up. A bit the cost of Hornsea's energy thanks to that being even more expensive than the guaranteed strike price due to the UK's new nuclear plants under construction.
But that's largely due to financial engineering rather than the real thing. In the UK's capacity auctions, there were some very low bids for offshore windfarms. The MSM rejoiced! Wind will soon be too cheap to meter! Not looking too closely at the small print, ie the price is unrelated to the cost, and a minimum. Not what any energy will be sold for on the markets.
