Construction costs for U.S. onshore wind generators declined by 27% from 2013-2019, according to data from the U.S. Energy Information Administration.
The average construction cost per kilowatt fell from $1,895 in 2013 to $1,391 in 2019. The report acknowledges that wind capacity and construction costs vary significantly by region.
Average constructions costs for onshore wind generators in the ERCOT region were $1,114/kW in 2019 – lower than the national average of $1,391. ERCOT added 3.5 gigawatts of wind capacity that year, the most of any region, according to EIA.
