Gigantic photovoltaic system at the Happel Stadium: Vienna relies on sun!

Ernst-Happel-Stadion, 1030 Wien, Österreich - On March 24, 2025, the photovoltaic system on the roof of the Viennese Ernst Happel Stadium was completed. The installation comprises over 9,000 modules that generate around 3,880 MWh of sun power a year. This amount covers the annual consumption of around 1,100 households and exceeds the electricity consumption of the stadium itself, such as press.wien.gv.at reported. Montage could be completed faster than planned to include an additional international match of the Austrian national soccer team in the schedule. 3D models of the stadium were used for the digital planning of the system.

The solar connection not only includes the photovoltaic system, but also an expansion by geothermal energy: 270 earth drilling was carried out at a depth of 150 meters under the training places. These comprehensive expansion measures were realized in cooperation with Vienna energie and the Viennese networks to ensure the cabling of the solar power system.

sustainable sports business

The project aims to make the Ernst Happel Stadium one of the first emission-neutral stadiums in Europe. The progress also includes switching the entire lighting system to LED technology, which not only increases energy efficiency, but also sustainably reduces electricity requirements. Sports City Councilor Peter Hacker emphasized the importance of these measures that promote the efficient use of energy in the stadium.

The new infrastructure also includes the renovation of the training places. These now offer six international competition sizes and are back in operation, which benefits the requirements of clubs such as SK Rapid and the Vienna Football Association. The President of SK Rapid, Alexander Wrabetz, emphasizes how important these improvements are for the long -term development of the association.

successful energy change in Vienna

Thanks to these initiatives, Vienna has already reached the goal of 250 MWP solar power output by the end of 2025, with over 50 MWP, which are installed on city's own areas. In the past five years, the solar power in Vienna has more than quintupled, which gives the potential to supply around 72,000 households with electricity. It is also estimated that these developments can avoid over 57,000 tons of CO2 annually.

These progress are part of a larger trend in energy generation: according to Destatis.de have renewable energies in 2023 18 % of electricity production in 2023 made out, with solar energy a considerable contribution. The proportion of renewable energies in the global energy mix is ​​to be further increased by 2030, which reflects the continued focus on sustainable energy sources.

Overall, the developments related to the Ernst Happel Stadium show that the city of Vienna not only invests in the sports infrastructure, but also takes a clear step towards a more environmentally friendly future.
