This data-file tabulates the capex costs of 35 offshore wind projects in the UK, with 8.5GW of capacity, which have been installed since the year 2000.
We model the incentive price for each project, i.e., the power price that is needed to earn a 10% levered but unsubsizided return. There is little evidence for deflation. Rather, breakevens appear to have risen at a 2.5% CAGR over the past decade.
Please download the data-file to interrogate the findings, or view the individual project parameters. Continued technical innovation is needed in the wind industry. We find new airship concepts could help deflate logistic costs.
