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.
that is an improvement of $ 30000 per mw per year though it is still a net cost in the original study wind energy cost $ 25300 per mw per year more than coal with the new figures the net costs become net benefits $ 31200 per mw per year cheaper than coal
