Assuming a 15% higher capacity factor for wind results in the LCOE of ofshore wind being 26% to 75% more expensive. The LCOE of ofshore wind, assuming a 45% capacity factor and USD 0.035/kWh O&M cost, is between USD 0.15 and USD 0.165/kWh. This range drops to USD 0.139 to USD 0.152/kWh when the capacity factor is 50%.
