How much of the time will the blades be turning?
The turbines will operate only when winds are 9 mph or higher on the ridge, which we estimate will be about 80% of the time. The turbines have internal gearing to maintain relatively constant rotation speed while allowing production of greater amounts of electricity as wind speeds increase. After winds reach roughly 30 mph, the turbines operate at fully rated capacity. Above 56 mph the turbines will shut down to protect themselves in storms.
