U.S. Installed Wind Capacity

1999 – 2016 (gigawatts)

Proof Point Findings

  • Wind Energy Installed Capacity – Maximum installed wind turbines potential output, covering residential, small commercial, commercial onsite, industrial, and utility-scale projects
  • Sustained U.S. Installed Capacity Growth – Grew 23% annually between 1999 and 2016, from 2.5 GW to 82.2 GW
  • Top States – Led by Texas with 20.3 GW total installed capacity in 2016, followed by Iowa with 6.9 GW and Oklahoma with 6.6 GW
  • Key Growth Drivers – Include continued government support (e.g. Production Tax Credits (PTC), Treasury grants, local and federal policy implementation), expanding wind turbine capacity through continuous technology innovation, and more efficient grid integration, enabled by increased participation from utility companies and system operators
