DOE to Debut a Dynamic 5-Megawatt Dynamometer

Boulder, Colorado -- As wind turbine capacity continues to grow, so does the need to test the electrical and mechanical power-producing components of those turbines. Currently, only a few test facilities worldwide have the capability to test wind turbine drivetrains with capacity ratings up to 5 megawatts--and DOE's National Wind Technology Center at the National Renewable Energy Laboratory is now one of them.
