Power station and weir

The power station and weir in Hagneck is a run-of-river hydroelectric facility on the Aare that uses flowing water to generate electricity. The installation includes weir structures and powerhouse buildings directly integrated into the river channel.

Construction of the facility began in 1897 after the canton of Bern granted permits to local municipalities. It represents one of the region's early hydroelectric developments.

The facility is part of Hagneck's protected townscape and forms part of the region's industrial identity. The mechanical installations integrate into the river landscape and shape how the place looks to visitors.

The facility sits directly on the river and is visible from walking paths along the Aare valley. Visitors can observe the structure and its operations from public areas without restricted access concerns.

The amount of electricity generated varies with seasons, as spring snowmelt brings significantly more water to tributary streams. This visible fluctuation shows how dependent hydroelectric power is on natural cycles.
