A hydroelectric dam is essentially a mechanical gateway that can control how often, how much, and how fast the water is allowed to passed through. Water above the dam is collected and stored into a reservoir.
Hydropower plants harness water's energy and use simple mechanics to convert that energy into electricity. Hydropower plants are actually based on a rather simple concept -- water flowing through a dam turns a turbine, which turns a generator. Here are the basic components of a conventional hydropower plant: A turbine can weigh as much as 172 tons and turn at a rate of 90 revolutions per minute (rpm), according to the Foundation for Water & Energy Education (FWEE). 2  Generators-As the turbine blades turn, so do a series of magnets inside the generator.
