Gösgen hydropower plant: Modernisation of the Winznau weir

In 2023 Alpiq will begin the refurbishment of the Winznau weir. The weir, which was commissioned in 1917, holds back the Aare in the municipality of Winznau and diverts water into a 4.8 kilometre canal leading to the Gösgen power plant. Within the context of the new concession for the Gösgen hydropower plant, Alpiq will invest in excess of CHF 63 million, among other things for the comprehensive modernisation of the weir.

Flumenthal hydropower plant, new fish pass

Alpiq will build a completely new fish pass at the Flumenthal hydropower plant. It will fulfil the current standards for fish migration in the River Aare. The construction work will be completed by the end of 2023. Alpiq Hydro Aare AG is investing 10.5 million Swiss francs.
