It was the strongest Q1 for installations since 2009 and the second strongest first quarter ever.
Installation activity was more robust than during the first three of quarters of 2016 combined, said AWEA.
More than 9GW is under construction and almost 12GW in advanced development, the highest level since AWEA began tracking both categories in of 2016.
GE Renewable Energy, Siemens, and Vestas captured 88% of the US wind turbine market during the first quarter, continued AWEA.
As much as 24% of the 2GW installed in Q1 was contracted to non-utility purchasers including the US Army and Google.
The boom is likely to last for some time, but it is set to fall. The Production Tax Credit is being phased out, ending in 2019 with the last projects completing by 2021.
The first quarter figures from the Federal Energy Regulatory Commission showed wind and solar provided 50.84% of the new electrical generating capacity added to the US grid.
