More than 600 visitors were able to experience the construction work for the new BB power plant in Obervellach and Mallnitz. Residents and interested parties from all over Carinthia did not want to miss out on this "major construction site in the Mlltal" experience. All construction areas and the tunnel construction sites were accessible to visitors. The youngest guests could let off steam in the children's adventure world at the new "Krafthaus". The tunnel and gallery tours had been fully booked for weeks. The dimensions of the underground tunnel system were particularly impressive. Christian Hss, OBB project manager: In the future, the underground storage tunnel will hold 60,000 m of water. We are pleased to be able to show the currently empty tunnel to interested members of the public as part of the tunnel tours.
The Obervellach II power plant at a glance
The Lassach and Obervellach power plants have been supplying energy for railway operations since the beginning of the last century. The systems are now at the end of their technical service life. With the construction of the Obervellach II power plant, a completely new, independent power plant will be created, which will replace the existing Obervellach and Lassach power plants. By 2024, in the municipality of Mallnitz
and Obervellach, three water intakes (Mallnitzbach, Dsenbach and Kaponigbach), an approximately 4 km long headrace, a 50 Hz small hydroelectric power station and a storage tunnel were built. The heart of the project is the new power house and the equalizing reservoir in the industrial area of ??Obervellach.
The energy generated in the future corresponds to approx. 30,000 rail jet journeys from Villach to Vienna. At the Obervellach site, the new construction of the traction current power plant will increase energy production by more than 35%.
BB is one of the largest climate protection companies in Austria
In addition to the sustainable savings of around 3.5 million tons of CO2 per year through transport services, energy is also an issue with leverage for climate protection. That is why BB has been using 100% traction current from renewable energies since 2018 and in 2019 they also switched train stations, offices, workshops and container cranes to green electricity. Around a third of the traction current that BB needs to drive its trains is produced by itself in eight of its own hydroelectric power plants and six photovoltaic systems. In order to be able to act even more independently of the market in the future, BB is continuing to increase its own production of electricity from renewable energy sources. In this way we create security of supply and a cheap traction power supply. This is important in order to reliably provide rail operations for our passengers.
