Please note that the CSV files can exceed the maximum worksheet size of Excel and the data can therefore only be displayed correctly in an alternative text editor (e.g. Notepad++).

Hydropower reserve

To ensure the security of electricity supply in Switzerland even in a shortage situation, a hydropower reserve is established annually. To procure the reserve, Swissgrid is conducting the tenders on behalf of the ordinance (WResV) before the hydrological year. The results of the tender are published here.
