Electric Power Plants A power station is an industrial facility for the generation of electric power.

ď Ż Conventional Power Plants ď Ż Non-Conventional Power Plants

Conventional Power Plants  Thermal Power Plants  Combined Cycle Power Plants  Nuclear power plants  Hydroelectric Power Plants

Thermal Power Plants ď Ż Water is heated in a boiler by the heat,

the steam that is generated moves the turbine connected to the generator.

Combined cycle power plants ď Ż They obtain electricity as the result of

two combined cycles: a cycle that uses air and gas, and a conventional thermal cycle.

Nuclear Power Plants ď Ż They use a nuclear fission reactor that

produces heat to generate the pressurised steam needed to move the turbine rotor.

Hydroelectric Power Plants ď Ż The energy of the height of the water

moves the blades of the turbine. There are two types: Gravity and Pump

Non-conventional Power Plants  Wind turbine  Solar power plants  Biomass thermal power plants  Geothermal power plants  Ocean power plants

Wind turbine ď Ż Use the kinetic energy of the wind to

move the blades of a rotor at the top of a tower.

Solar Power Plants ď Ż Use the Sun’s energy. There are two

types: Photo-thermal power plants and Photovoltaic power plants.

Biomass Thermal Power Plants ď Ż They are thermal power plants that use

biomass as a fuel.

Geothermal Power Plants ď Ż Use the heat found at deep layers in the

Earth.

Ocean power plants ď Ż Use the energy from the oceans and seas:

Tides, waves or thermal gradient.
