5.3 Operating Expenditures for Offshore Wind There has been no indication that expected operating expenditures for offshore wind projects have shifted between 2010 and 2013. The OpEx baseline for 2013 was assumed to be $40/MWh, equivalent to $136/kW/yr, with a range extending from $20/MWh to $70/MWh.
Cost per Unit of Output. While there is no available average cost of a wind turbine, there is, at least for large turbines, an average cost per megawatt. In 2015, it was about $2 million per megawatt. The SeaTitan 10MW, therefore, although not priced at the time, could cost in the neighborhood of $20 million.
