Entegrity Wind Systems
Entegrity Wind Systems' EW50 wind turbine.
Text Version
As part of the National Renewable Energy Laboratory and U.S. Department of Energy (NREL/DOE) Independent Testing project, NREL plans to test Entegrity Wind Systems' EW50 turbine at the National Wind Technology Center (NWTC). The EW50 is a 50-kW, three-bladed, horizontal-axis downwind small wind turbine. The turbine's rotor diameter is 15 meters, and its hub height is 30.5 meters. It has a three-phase induction generator that operates at 480 volts AC.
