Types of Hydropower Turbines | Department of Energy

There are two main types of hydropower turbines: reaction and impulse. The type of hydropower turbine selected for a project is based on the height of standing water—referred to as "head"—and the flow, or volume of water over time, at the site. Other deciding factors include how deep the turbine must be set, turbine efficiency, and cost.

The Power Curve The diagram below shows the power output of a turbine against steady wind speeds. The cut-in speed (typically between 6 and 9 mph) is when the blades start rotating and generating power. As wind speeds increase, more electricity is generated until it reaches a limit, known as the rated speed. This is the point that the turbine ...
