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.
Lastly, transmission line investment costs to get new wind power to the electricity grid add 2.7 cents per kilowatt hour. Thus, the total cost for wind power, including the hidden costs, averages 15.1 cents per kilowatt hour for natural-gas fired back-up and 19.2 cents per kilowatt-hour for coal-fired back-up.hus, the total cost for wind power, including the hidden costs, averages 15.1 cents per kilowatt hour for natural-gas fired back-up and 19.2 cents per kilowatt-hour for coal-fired back-up.
