950 MW, Moray East Offshore Windfarm [MEOW] employing the very latest 9.5 MW wind turbines and costing £1,800 million will have an average cf over its 25 year lifespan of 31.25% and will generate 2.6 TWh of intermittent electricity p.a.. 45.75 MEOWS would be needed to generate 119 TWh at a total cost of £82,365 million.

By comparison, 3,200 MW, Hinkley Point C [HPC] nuclear power plant, the most expensive form of npp by some 20%, will operate at a capacity factor of 90% over its 60 year design life. For a cost of £18,000 million, it will generate 25.2 TWh of 24/7 electricity p.a., so 4.72 HPCs would be needed at a total cost of £84,903 million.

But that’s not the end of the story, because those 45.75 MEOWs would have to be built a 2nd time and be 10 years into their 3rd build to deliver their intermittent electricity for the 60 year life of a npp.

That’s a factor of X2.4 and a total cost of £197,676 million.
