In 2011, DOE made awards to six groups for a Phase I study into innovative drivetrain technologies that could be scaled to larger turbines. From these Phase I studies, two consortia were selected for Phase II awards intended to demonstrate the technologies’ commercialisation potential. The Next Generation Drivetrain (NGD) consortium is led by DOE’s National Renewable Energy Laboratory (NREL) and includes wind turbine, gear systems, power electronics and PM generator manufacturers and drivetrain specialists. During Phase I, the NGD team identified innovations to the gearbox, PM generator and power electronics that will enhance wind turbine drivetrains’ capacity and reliability. In Phase II, these innovations will be incorporated into a scalable 1.5MW prototype that will be tested at NREL.
