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.
The cost to develop and build a wind energy facility is approximately $1.3 million to $1.7 million per megawatt, compared to a cost for gas-fired energy generation of $800,000 per megawatt.
