In last week’s Wind View, we stacked a turbine tower. This week we’re moving upward to set a nacelle.
You might have noticed that the tops of wind turbines can vary in size and shape. Some are rounded like golf balls, and others are rectangular like school buses. That rounded or rectangular component on top is the nacelle: its purpose is yawing (rotating) into the wind so the turbine’s rotor can continue spinning and generating power. The nacelle’s shape is determined by the type of generator the wind turbine is using.
You can see in the video below that One Energy’s nacelles are rounded, that’s because we use direct drive generators, which means that they don’t require a gearbox.
