How Hydropower Works | Department of Energy

At the plant level, water flows through a pipe—also known as a penstock—and then spins the blades in a turbine, which, in turn, spins a generator that ultimately produces electricity. Most conventional hydroelectric facilities operate this way, including run-of-the-river systems and pumped storage systems .

How Do Energy Transformations Occur in a Hydroelectric Plant?

A hydroelectric power plant converts the energy of flowing water into electricity. This is done by using a turbine to generate electricity. The turbine is turned by the force of the water, which is then used to power a generator. The generator converts the mechanical energy of the turbine into electrical energy.

Microhydropower Systems | Department of Energy

Microhydropower Systems. Microhydropower can be one of the most simple and consistent forms or renewable energy on your property. If you have water flowing through your property, you might consider building a small hydropower system to generate electricity. Microhydropower systems usually generate up to 100 kilowatts of electricity.

A brief history of hydropower

The world''s first hydroelectric project was used to power a single lamp in the Cragside country house in Northumberland, England, in 1878. Four years later, the first plant to serve a system of private and commercial customers was opened in Wisconsin, USA, and within a decade, hundreds of hydropower plants were in operation.

Water turbine

OverviewHistoryTheory of operationTypes of water turbinesDesign and applicationControl systemsTurbine blade materialsMaintenance

A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy.

Hydraulic head

Français. The hydraulic head is a value that measures the amount of mechanical energy available in water in a river, stream or even lake. The hydraulic head is equivalent to the water level in a static (non-flowing) water body. [1] In its simplest form hydraulic head is a measurement of the height of a static water column above an arbitrary ...
