The domestic wind power industry in the United States installed 1,661 MW in the second quarter of this year, which represents a record for second quarter installations, the American Wind Energy Association said in a July 22 report.
The 1,994 MW installed in the first two quarters of 2015 is more than double the capacity installed in the first half of 2014. The U.S. now has an installed wind capacity of 67,870 MW and over 49,000 wind turbines.
There are over 13,600 MW of wind currently under construction, continuing near-record levels of construction activity. Over 800 MW of new power purchase agreements (PPA) were also signed in the second quarter of 2015, AWEA said.
More than 19 percent of construction activity is being reported from the Plains states, from Nebraska to Oklahoma, AWEA said in an executive summary of the quarterly report.
The most capacity was installed in Texas (1,226 MW), followed by Oklahoma (150 MW), California (107 MW), Illinois (99 MW) and South Dakota (80 MW), AWEA said in a quarterly market report.
Texas now has over 15,000 MW of installed capacity and California has over 6,000 MW, the wind association said.
Given construction activity, Iowa is currently on pace to overtake California and become the second-ranked state in installed capacity by the end of 2015, AWEA reported.
The quarterly report was released on the day after the Senate Finance Committee endorsed a “tax extenders” package that includes provisions to extend the production tax credit (PTC) and investment tax credit (ITC) that encourage construction of more U.S. wind generation.
