First solar-wind hybrid park with multifunctional land utilisation

The existing Gugelberg wind farm with three wind turbines was supplemented this year by a fourth turbine and an agri-PV system - the EWS Sonnenfeld Pellendorf. Together they are the first hybrid farm of its kind in the municipality of Gaweinstal in Lower Austria to generate green electricity for around 14,000 households. Synergies from bundled wind and solar energy generation lead to optimised use of the grid connection and grid capacities.

Combine what belongs together.
Use what makes sense.

Three Vestas V112 wind turbines with a hub height of 140 metres and a total output of 9.9 MW have been generating wind power at the Gugelberg wind farm since 2017. The wind farm has now been expanded to include a fourth Vestas V162 turbine with a hub height of 169 metres and an output of 6.2 MW. In addition, a 3.3 MWp agrivoltaic system has been installed, which feeds solar power into the Gaweinstal substation via the wind farm's existing grid connection.

EWS not only handled the construction management of the 3 + 1 wind turbines, but also planned, delivered and realised the EWS Sonnenfeld Pellendorf for the company Gugelsolar as EPC contractor. EWS is also responsible for the technical management of the agri-PV plant, which was built on a total area of 4 hectares and is primarily used for agricultural purposes, with an actual loss of only 2% of the area for solar power generation.

Karl-Heinz Hofer, Project Manager Construction Management at EWS and responsible for the electrical engineering and grid connection of the project: "The EWS Sonnenfeld Pellendorf, including the expansion of the Gugelberg wind farm by a fourth wind turbine, was a special and unique challenge for us. Less than a year ago, our colleagues in Munderfing were fighting for the licence and the start of construction, and now the hybrid farm is generating clean electricity. We have thus set a milestone: the first wind and agri-PV hybrid farm is connected to the grid!"

plenty of power generation on a small area - the eco-hybrid park³ may succeed

Alongside the EWS Sonnenfeld in Bruck/Leitha, the EWS Sonnenfeld Pellendorf is already the second successfully realised agrivoltaic plant and the first hybrid farm combining wind energy and agrivoltaics.

In addition to maximum green electricity generation with optimised use of the grid connection, the top priority of the hybrid wind and agrivoltaic farm is maximum land use efficiency. You can read about further advantages in the news article "Hybrid power plant - the energy system of the future".

"The major advantages of hybrid parks of this type are that a grid infrastructure can be better utilised through the combined generation of solar power in the summer months and during the day and wind power in the winter months and at night. This also means that there are no additional grid access costs for the operator," says Karl-Heinz Hofer and continues: "Due to the current grid situation and the ongoing grid expansion, the combination of an EWS Sonnenfeld® with a wind farm grid access is the next step towards an energy future that conserves land resources!"

• If you own a suitable plot of land (designated zone, close to a substation) and are interested in realising a hybrid park³, please contact us. We will find the best solution for your site.
• If you would like to combine your existing wind farm with an agri-PV system, please contact us. We will check the possibilities quickly and without obligation and will also be happy to take care of the realisation

With your renewable hybrid energy project with multifunctional land utilisation, you are making a particularly soil-friendly contribution to reducing CO₂ emissions and thus to curbing global warming.
