Wind turbines are the one component that wind farms simply cannot do without. More than 100 wind turbine manufacturers exist globally, offering as many 1,000 turbine models. No single turbine is the right fit for every application.
In the following pages, Wind Systems has compiled news, turbine models, and general specifications from common utility-scale wind turbine manufacturers, in its inaugural Turbine Directory.
Ten turbine manufacturers were selected for this directory, based on U.S. wind energy capacity installed during 2012* (Source: AWEA U.S. Wind Industry Annual Market Report Year End 2012).
Technical specifications were taken from manufacturers’ literature or otherwise provided by the manufacturers. Readers should contact the turbine manufacturer directly for complete specifications.
* Companies with top-ten 2012 market share that have ceased manufacture of new wind turbines were not included in this directory.
General Electric’s onshore wind turbine portfolio consists of five models ranging from 1.7 to 3.2 MW, with various configurations to meet project requirements. GE is the top wind turbine manufacturer in the U.S., with 3,003 turbines (5,014 MW) installed during 2012, accounting for a 38.2 percent market share. GE turbines account for more than 24 GW of installed wind power capacity in the U.S. Table 1
