Turbine Manufacturers & Rankings

2014 Annual Market Report OEM Market Share

  • Approximately 48,000 wind turbines make up the U.S. wind turbine fleet of 65,877 MW.

  • The top three wind turbine manufacturers, measured by cumulative share of the U.S. wind turbine fleet, are GE Energy, Vestas, and Siemens.

  • GE Energy continued its streak as the leading wind turbine manufacturer in the U.S. market during 2014, installing 66% of all utility-scale turbines. It has maintained top market share for U.S. installed capacity for the past 14 years.
  • The average turbine rating of a wind turbine installed during 2014 was 1.94 MW. This marks an increase from 2013’s average wind turbine rating of 1.87 MW.
  • The average rotor diameter of a wind turbine installed during 2014 was 99.7 meters for turbines 1 MW and larger. The average hub height of a wind turbine installed during 2014 was 82.4 meters. These taller towers allowed for wind projects to be sited with more frequency during 2014 in the Great Lakes region.
