Strubklamm power plant, Heritage power station in Adnet, Austria
Strubklamm is a hydroelectric power station in Adnet featuring a concrete dam 80 meters long and 36.5 meters high, holding a reservoir of 2.5 million cubic meters. The facility has two large spillways on the left side of the valley for flood regulation and a bypass tunnel for reservoir drainage.
Construction began in November 1920 but faced financial obstacles until a contract with Württembergische Landes-Elektrizitäts-AG secured the necessary funding. This made it one of the early major hydroelectric projects in this Austrian mountain region.
The complex preserves a workers' settlement and the original machinery building from 1924, both protected as heritage monuments. Visitors can still observe traces of early industrial life in this mountain setting.
The site allows good views of the facility's complex water management system, especially the different openings and their functions. Visitors should be prepared for uneven terrain and stay alert near water and rock faces.
Water travels through a pressure tunnel blasted into dolomite rock stretching over 2.400 meters, capable of moving more than 9 cubic meters per second. This underground route is the heart of power generation but remains hidden from visitors.
