Area photovoltaic plant Schönkirchen-Reyersdorf
- Savings of about 14,000 tons of CO2 per year in total (compared to fossil electricity production with coal)
- Electricity production corresponds approximately to the annual electricity consumption of 4,400 households
- Commissioning of phase I of the plant was carried out in the fourth quarter of 2020
- Commissioning of phase II was carried out in the third quarter of 2022
Construction of one of the largest area photovoltaic (PV) plants in Austria
The first phase of the PV plant was constructed on open land on OMV's premises in Schönkirchen-Reyersdorf and commissioned on November 19, 2020. The commissioning of phase II took place in July 2022. The total installed capacity of the PV plant in question amounts to 15.32 MWp in the final stage, which OMV Austria Exploration & Production GmbH feeds into the company-specific 20 kV grid.
The aim of this project is to generate own electricity consumption in a climate-friendly way with the help of solar energy. As a result, there will be CO2 savings of around 4,300 t/a (based on the current electricity mix) or up to 14,000 t/a (compared to fossil electricity production with coal).
At the landfill site in Schönkirchen-Reyersdorf there is a green open area of 133,200 m² available, which is suitable for the use of photovoltaic modules. The enclosure of the PV plant is ensured by the existing fencing of the Schönkirchen-Reyersdorf landfill site.
General plant description
The planned power generation plant will generate electrical energy from a renewable energy source. Solar energy is used as the primary energy source. Monocrystalline solar cells convert the solar energy directly into electrical energy. The direct current generated is converted into alternating current by inverters and fed into the internal 20 kV grid of OMV Austria Exploration & Production GmbH via transformers.The PV plant is operated in parallel with the grid, with all the electrical energy produced being used directly by the plant operator.
A new 20 kV ring line was built around the plant for the feed-in. Along this ring line, prefabricated compact transformer stations with a capacity of 800 kVA each were located and a transfer station was erected.
Technical data of the mounting system
The modules are positioned using a static free-space mounting system. The modules are installed horizontally in rows facing east or west. The foundation is made by means of pile-driven/concrete foundations.
