Facts at a glance
Total power (in megawatts peak) 24.5 MWp
Area used for installation of the PV system (in hectares) 14 ha
Degree of coverage of the PV modules 42 %
Total number of PV modules approx. 45,000 units
Expected annual yield (in megawatt hours) 26,700 MWh
Number of households supplied around 7,500
ECOwind and EVN are constructing a Floating-PV system north of the town of Grafenwörth (Lower Austria). This is a photovoltaic (PV) system that floats on the water – it will be the largest of its kind in Central Europe. It consists of two sub-areas of Teich Nord and Teich Süd (North Pond and South Pond) and will be installed over an area of around 14 hectares. The output of the combined plants will be approx. 24.5 MWp, capable of supplying around 7,500 households with green electricity in the future.

The main benefits of a Floating-PV system at a glance

The Floating-PV solar application means that we can make good use of otherwise underutilised expanses of water. In an environment where there is limited available space, such systems are an extremely valuable supplement to more traditional solar installations on roofs or on land.

Johann Janker, Managing Director ECOwind

The main challenges of this project were gaining approval for the installation of a new PV technology in Austria and the local conditions on the construction site with a 7m difference in level between the installation area and the water.
