Obervellach II power station
OEBB relies on timber construction

For more than 100 years, OEBB has relied on environmentally friendly electrical power generation in the form of hydropower and is thus considered a pioneer in electric mobility. The Lassach and Obervellach I power plants can look back on a history of almost 100 years and are now being replaced at the end of their technical service life by the Obervellach II hydropower plant. This will increase the production of electricity from hydropower by more than 30 %.

OEBB is also relying on timber construction and the products of the HASSLACHER Group for the renovation of the existing powerplant group. The main supporting structure of the impressive roof construction consists of prefabricated glulam lattice girders, which were delivered to Obervellach from the HASSLACHER site in Hermagor by means of special transport. The secondary supporting structure comes from the HASSLACHER site in Stall im Mölltal and consists of around 210 m³ of cross laminated timber elements, which on the one hand support the roof and the loads and transfer these to the main girders and on the other hand form an attractive timber soffit for the Obervellach II hydropower plant.
