Ventera's VT10 wind turbine. Text Version
As part of the National Renewable Energy Laboratory and U.S. Department of Energy (NREL/DOE) Independent Testing project, NREL is testing Ventera's VT10 small wind turbine at the National Wind Technology Center (NWTC). The VT10 is a downwind, horizontal-axis, three-blade turbine. Its diameter is 6.7 meters, and it is mounted to a lattice tower with a hub height of 21.7 meters. The VT10 uses a single-phase, grid-connected, permanent-magnet generator that is rated at 10 kW at 240 volts AC.
