Schönkirchen-Reyersdorf – one of the largest photovoltaic area plant in Austria

Photovoltaics, as a renewable energy, are an important step towards the energy transition. Therefore, one of the largest area photovoltaic plant was built on the OMV landfill site in Schönkirchen- Reyersdorf at the end of 2020 to generate its own electricity consumption in a climate-friendly way with the help of solar energy. The commissioning of the second expansion phase was carried out in July 2022.


The plant

With the power generation plant completed in two expansion phases on the 13.3 ha green field at the OMV's landfill site, electrical energy is generated from renewable solar energy. The total installed capacity in the final stage after completion of phase II at the beginning of July 2022 is 15.32 MWp with a generation of 15.84 GWh, which corresponds to the annual electricity consumption of around 5,000 households and an average CO2 savings of 10,000 t/a.
