Design of the 1000 MW Lagobianco pumped-storage scheme

Switzerland plays a key role on the European electricity market, having operated pumped-storage plants for decades. More than 900 Swiss companies are today involved in the production, distribution and regulation of electricity. Customers in the industry are particularly keen to obtain daily peak energy with attractive prices. In 2008, Repower AG, the fourth largest energy distributer in Switzerland, started work on the development of the Lagobianco project, a 1000 MW pumped-storage in the Swiss Alps. This paper gives an overview of the final design of the scheme with its optimized main structures and characteristics.
