Developers added 7,017 MW of new wind capacity in 2017 representing an investment of $11 billion, the American Wind Energy Association reported.
Of that, 4,125 MW came online in 29 new wind facilities in the fourth quarter alone.
AWEA indicated 28,668 MW of wind facilities are now under construction or in advanced development, up 34 percent from the end of 2016.
“Wind delivered big results for the U.S. economy in 2017. Building new wind farms keeps American factory and construction workers busy, while breathing new life into farming and ranching communities,” said Tom Kiernan, CEO of AWEA. “This American success story will continue, with the wind project construction and advanced development pipeline four times greater than the amount installed in 2017. That means tens of billions in additional infrastructure investment is on its way to the United States of America.”
Texas lead the fourth quarter for new wind capacity with 1,179 MW installed. Oklahoma overtook Iowa in the fourth quarter to rank second in the nation for total installed wind capacity at 851 MW. Iowa finished with 334 MW, followed by Illinois at 306 MW and Missouri at 300 MW.
There is now 89,077 MW of wind power installed across 41 states.
Power purchase agreements reached 5,496 MW for the year, with 710 MW of that signed in the fourth quarter by non-utility customers.
The average price of wind energy fell four percent for the year, on top of a two-thirds decline from 2009 to 2016.
Repowerings have become more common, with 2,136 MW of partial repowerings over 15 facilities in 2017.
Offshore wind projects in development have grown to 490 MW.
