At 42% capacity factor of 2,600MW, 24 hours and 365 days in a year, that's 9,600,000 MWh in a year. At a 30 year lifespan, the capital expenditure is $330M/year

At 42% capacity factor of 2,600MW, 24 hours and 365 days in a year, that's 9,600,000 MWh in a year. At a 30 year lifespan, the capital expenditure is $330M/year, for an average cost of $34/MWh. This is basically unbelievably cheap for offshore wind, and if you would tel someone 10 years ago this price, they probably wouldn't believe you. Wind typically has very low operations and maintenance costs compared to the CapEx, but even at 20%, the cost is still less than $45/MWh, which is incredibly cheap. Of course this doesn't factor in the time value of money, but to see raw numbers like this for offshore wind, which historically has been quite a bit more expensive, is a bit shocking to me.
