Lünerseewerk, Pumped-storage power station in Tschagguns, Austria.
The Lünerseewerk is a pumped-storage power station in the Montafon valley that extends 380 meters and uses water from reservoirs at different elevations. The facility connects two lakes through pressure pipes, moving water between basins to generate electricity based on demand.
Construction of the facility began in 1954 and operations started in 1958 as part of Austria's post-war infrastructure recovery. Its completion marked a turning point for energy supply in Vorarlberg and established hydropower as central to the region's development.
The station shaped the valley's development as energy infrastructure that powered the region for generations. Walking past it today, you encounter a landmark of Austrian industrial achievement that became part of the landscape's identity.
The station lies near Tschagguns and is surrounded by mountain slopes that offer good views of its technical structures. Access is best from valley-level trails, and the views of the facility and surrounding lake vary with seasons and water levels.
The station operates as part of the Almkanal system, an older irrigation network that carries water through the same mountain landscape, blending electricity production with traditional water management. This connection shows how modern technology builds on and adapts historical water routes.
