Overall, wind farms cost in the area of $1,000 per kW of capacity, so a wind farm consisting of seven 1.8-MW turbines runs about $12.6 million.
The weighted average electricity cost of new onshore wind farms in 20142 was between USD 0.06 to USD 0.09/kWh depending on the region, but costs can be as low as USD 0.05/kWh for the most competitive projects without financial support.he cost of electricity from wind is falling. This is due to total installed costs declining in line with lower wind turbine prices since 2009 and, at the same, technology improvements mean more wind is harvested from the same site with new wind turbine technologies.
