Turning the power of water into electricity

Ruppoldingen hydroelectric power station

The three run-of-river power stations operated by Alpiq Hydro Aare AG utilise the waters of the River Aare to generate environmentally friendly electricity for some 150,000 households.

Turning hydro power into electricity has been a traditional strength of Alpiq's since 1896. This form of energy generation is environmentally compatible, CO2-free and natural. Alpiq Hydro has been responsible for operating a trio of run-of-river power stations on the banks of the Aare at Flumenthal, Ruppoldingen and Gösgen since 2000. The three power stations produce electricity efficiently and cost-effectively using the latest technology. Between them, they generate more than 500 million kWh of electrical energy a year: equivalent to the consumption of around 150,000 households.
