Tallbloke har en kritisk gjennomgang av økonomien i det nye Hywind prosjektet i Skottland;
Meanwhile, the operating costs are either disappointing or disastrous, depending on your view of the world. A fixed offshore windfarm like Rampion – of similar vintage to Hywind – has operating costs of around £150,000/MW. On that basis, Hywind’s £200,000 per megawatt is very disappointing. On the other hand, renewables advocates claim that the true operating costs of fixed offshore wind are well below £100,000/MW. If that’s the case, and floating offshore is supposed to be cheaper to maintain, then Hywind’s performance could be seen as a disaster.
All this means that the underlying economics of the project are appalling. Hywind only managed to clock up £5 million of electricity sales, and its underlying position is a loss of £15 million or so. Still, the developers will not be overly worried; subsidies from the government brought in another £29 million of income, and so they are sitting pretty on a profit of £13 million.
Why would they care about their operating costs?https://tallbloke.wordpress.com/2020/10/18/hywind-low-economics-the-cost-of-floating-offshore-wind-power/
