How much does a 900 MW power plant cost?

With costs of just over 2 billion Swiss francs, the project will be an important component of the Swiss and European energy strategy. Thanks to the installed capacity of 900 MW, the power plant will be able to produce large amounts of electricity or store energy within a very short time.

How does the Vieux-Emosson power station work?

The water stored in the upper reservoir of Vieux-Emosson, which has a storage capacity of 227,000,000 m3, or 20 million kWh, falls into the underground power station via two vertical shafts that are 425 m high. The project was built at a cost of approximately CHF 2 billion ($2.09 billion) and saw the participation of 60 enterprises.

What equipment is used in Nant de Drance pumped storage power plant?

The six vertical reversible Francis pump-turbine units of maximum 157 MW each and the vertical asynchronous motor-generator units of 170 MVA as well as other central plant elements constitute the core equipment of the Nant de Drance pumped storage power plant. Martin Aemmer, then Head of Business Unit Hydro, Switzerland:

How does the Emosson power station work?

It uses the Emosson and Vieux Emosson reservoirs to operate. The water stored in the upper reservoir of Vieux-Emosson, which has a storage capacity of 227,000,000 m3, or 20 million kWh, falls into the underground power station via two vertical shafts that are 425 m high.

What if we don't have the right energy storage mix?

Dr Holger Wolfschmidt from Siemens Energy explains why without the right quantity and energy storage mix in place, we won’t be able to stabilise the grid, decarbonise power generation, secure energy supply and make sector coupling possible.
