Pumped energy storage generator manufacturer

How profitable is a pumped storage power plant?

The profitability of a pumped storage power plant results primarily from power market price variabilities at different points in time. The Limmern pumped storage plant (LPSP) is one of Axpo's most important expansion projects in recent years with investments amounting to CHF 2.1 billion.

What are pumped storage power plants?

Pumped storage power plants are currently the most economical way of efficiently storing large amounts of energy over a longer period. As the leading technology for energy storage services, pumped storage not only balances variable power production, but with its firm capacity it also serves as a reliable back-up.

Are pumped power plants an economic solution for large-scale energy storage?

As a result, an economic solution for large-scale energy storage is becoming more important. Pumped storage power plants are currently the most economical way of efficiently storing large amounts of energy over a longer period.

What type of generator is used in a pumped-storage power station?

The most common type of generator for pumped-storage power station is a reversible type, called a generator-motor. Toshiba has had an abundance of manufacturing achievements for more than 120 years, and has supplied various types of high-reliability, high-performance hydro-generators and generator-motors all over the world.

What is a pumped storage power station?

Their special feature: They are an energy store and a hydroelectric power plant in one. If there is a surplus of power in the grid, the pumped storage power station switches to pumping mode – an electric motor drives the pump turbines, which pumps water from a lower reservoir to a higher storage basin.

Are pumped storage facilities a viable solution for multi-functional power plants?

As multi-functional power plants, pumped storage facilities have a high potential to meet this challenge, because their technology is based on the only long-term, technically proven and cost-effective form of storing energy on a large scale, thereby making it available at short notice.
