Hydro Power
Generation

"Hydro power" generates power by utilizing the energy of water falling from a higher position to a lower position. One of these hydro power generation systems is a "pumped-storage system" , which pumps up water from a lower reservoir to a higher reservoir during off-peak hours and generates power by dropping water from the higher reservoir to the lower reservoir during peak hours. We manufacture an entire generation system for these power plants.


Since hydro power emits a minimal amount of CO2, which is known to be a cause of environmental pollution and global warming. Effective use of hydro power is being revalued throughout the world these days. "Hydro power" is an eco-friendly renewable energy that generates power by harnessing the potential energy of water. It is incorporated into the natural cycle of the Earth and offers clean energy.

Toshiba's hydro power generation systems are at the world's top level in achievements and technologies

Toshiba's hydro power generation systems are at the world's top level in achievements and technologies In the field of Francis turbines, which are most widely adopted, Toshiba is at the world's top level in their generation efficiency. Also in the field of pumped-storage power generation that addresses a varying peak load, Toshiba is at the world's top class in achievements and technological level amid the trend toward a higher head, larger capacity and variable speed.


Toshiba not only designs, manufactures and delivers the main equipment, such as hydro-turbines and hydro-generators, but it also delivers various components needed for power plants, and provides a total engineering service package from procurement and installation to testing and commissioning works.

What is hydro power?
