Wind energy costs for 2015 are compared to 2014 costs in WindPower Monthly. It also compares with costs of nuclear and fossil-fuel based generation. Following is a tabular representation of the low and median costs for onshore and offshore.
Onshore | Offshore | ||||
Low | Median | Low | Median | ||
2015 | Turbine, $/kW | $ 1,070 | |||
TIC, $/kW | $ 1,200 | $ 1,700 | $ 4,000 | $ 5,000 | |
O&M, $/MWh | $ 19 | $ 40 | |||
GC, $/MWh | $ 50 | $ 78 | $ 150 | $ 192 |
TIC: Total Installed Cost
O&M: Operations and maintenance cost
GC: Generation cost (assuming it is same as levelized cost of energy

I always enjoy this graphic from David Millborrow's article, it encapsulates total installed cost and capacity factor (wind speed):
