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.
