Technology The Rose Rock Wind Farm will incorporate 50 turbines rated at 2 MW each. These modern generators are robust, sophisticated, high-tech machines designed to capture the kinetic energy of the wind and convert it into electricity. Wind turbines consist of three main parts: the tower, the blade and the nacelle. Most of the action takes place inside the nacelle, where the motion of the wind turning the blades is converted into electricity. The blades are attached to a shaft that runs into a gearbox. The gearbox steps up the speed of rotation, which then turns the generator producing AC electricity. Electricity must be produced at just the right frequency and voltage to be compatible with the utility grid.
