With three new photovoltaic systems, motorway operations in the state of Salzburg BECOME even more environmentally friendly. With a peak output of 304 kWp, the largest system (688 modules) is currently going into operation on the roof of the Salzburg motorway maintenance facility on the western motorway.
It supplies clean energy not only for the large ASFINAG site in Liefering with its motorway maintenance depot and offices, but also for the nearby motorway tunnel. The new system in the state capital WILL bring an annual yield of up to 305,000 kilowatt hours, which is consumed directly on site, especially for the energy-intensive entrance lighting of the tunnel.
“We are equipping more and more of our locations with photovoltaic systems to generate green energy. This is an important focus of our climate protection program. A special focus is on tunnels, as these systems have the greatest energy requirements in our network,” says ASFINAG board member Hartwig Hufnagl.
Further south on the A 10 Tauern Autobahn, a so-called PV free-field system with 175 kWp is now in operation, which was built for the St. Michael toll station. From November, new modules on the Oberweißburg enclosure (162 kWp) will feed both the noise protection tunnel itself and the St. Michael im Lungau motorway maintenance facility.
For comparison: a family of four needs around 5,000 kilowatt hours of electricity a year. With the electricity generated from solar energy by the three new plants in Salzburg, more than 136 households could be supplied for a year.
ASFINAG is investing around 620,000 euros including subsidies in this photovoltaic infrastructure. The total CO2 emissions saved by the three systems amount to around 320,000 kilograms per year.
