Description

Initial capital costs of bottom-mounted offshore wind farms are analyzed by using an engineering model considering water depth, distance of coast and number of turbines. The parameters in the engineering model are identified with detailed cost data of a standard wind farm. The initial capital costs of the existing bottom-mounted offshore wind farms calculated by the engineering model and a parametric model are compared with the existing cost data in Europe. The engineering model shows a good agreement with the existing data by taking account of the size increase effect of wind turbine and construction vessels, the parametric model underestimates some existing data. Scenarios for the initial capital cost reduction in Japan are discussed.
