Graz Airport is the first Austrian regional airport to take a significant step toward carbon neutrality. A new, underground 400 Hz ground power supply has been installed at six aircraft parking positions, enabling emission-free and silent operation. The energy required for this system is partially generated by a new photovoltaic system on the roof of the parking garage, which was specially integrated into the system.
Graz Airport's management, Wolfgang Grimus and Jürgen Löschnig, expressed their delight at this progress on the path to becoming a "Green Airport." They emphasized that the new technology not only contributes to reducing emissions but also significantly improves the working conditions of ground staff, as they are no longer exposed to the exhaust fumes and noise of the existing diesel-powered ground power generators.
The commissioning of the new ground power supply will save approximately 24.000 liters of fossil fuel annually, corresponding to a reduction in CO₂ emissions of approximately 79 tons. This measure is part of a broader sustainability strategy of Graz Airport, which aims to continuously minimize its environmental impact and play a pioneering role among regional airports. Various projects to increase energy efficiency and reduce emissions have already been implemented in the past.
