Austrian renewable energy company PÜSPÖK has completed what it describes as Europe’s second-largest super-hybrid power plant in Nickelsdorf, combining wind power, photovoltaic generation and battery energy storage through a shared infrastructure system.
The project, supported by financing from the European Investment Bank (EIB) and Erste Bank, is designed to strengthen the integration of renewable energy into the electricity grid while contributing to Austria’s energy independence and climate-neutrality goals. The EIB is providing €57 million in new financing, bringing its total commitment to PÜSPÖK projects to approximately €200 million.
According to the company, the super-hybrid facility integrates wind turbines, solar generation and battery storage in a single system, allowing existing grid connections to be used more efficiently while increasing flexibility within the energy system. The combination of the three technologies is intended to improve grid stability and support a more reliable supply of renewable electricity.
“With the Nickelsdorf super-hybrid park, we are demonstrating what the energy supply of the future looks like: renewable, flexible and independent of fossil fuels,” said Lukas Püspök, Chief Executive Officer of PÜSPÖK.
A key component of the project is agrivoltaics, which combines agricultural production with solar power generation by installing photovoltaic systems on farmland and grassland. The approach enables dual land use while maintaining agricultural yields and generating renewable electricity.
PÜSPÖK said its agrivoltaic and wind power installations already supply clean electricity to more than 338,000 households. The company is also developing what it describes as Austria’s largest battery storage facility at the Nickelsdorf site. Once operational, the storage system is expected to add significant flexibility and energy storage capacity to the project.
Across all currently planned developments, PÜSPÖK expects to deploy 336.4 megawatt-peak (MWp) of agrivoltaic capacity and 246 megawatt-hours (MWh) of battery storage capacity. The battery storage facility is scheduled to enter operation in June 2026, with an official inauguration planned for July.
During a visit to the site, EIB Vice-President Karl Nehammer, Erste Bank Chief Executive Officer Gerda Holzinger-Burgstaller, State Secretary Elisabeth Zehetner and Burgenland provincial councillor Heinrich Dorner reviewed the progress of the project and its role in Austria’s energy transition.
“The expansion of renewable energy and modern storage technologies is crucial for Europe’s competitiveness, energy security and climate goals,” said Nehammer. He added that the combination of wind, solar and storage technologies strengthens Europe’s energy independence and supports the transition to a climate-neutral economy.
Erste Bank said its participation reflects its commitment to financing energy infrastructure projects that support both security of supply and decarbonisation.
“This project strengthens Austria’s energy independence and demonstrates how the energy transition can be implemented in practical terms,” Holzinger-Burgstaller said.
PÜSPÖK is one of Austria’s leading private renewable electricity producers. The company operates 114 wind turbines and several large-scale solar parks, generating more than one terawatt-hour of electricity annually, equivalent to around 2% of Austria’s total electricity demand.
The company said the Nickelsdorf project illustrates how supply security, grid stability and economic efficiency can be combined within modern energy systems. PÜSPÖK also announced that additional hybrid power plants are under construction in Gattendorf, Mönchhof and St. Andrä and are expected to enter operation progressively in the coming months.
The project forms part of the European Union’s REPowerEU programme, which aims to reduce Europe’s dependence on imported fossil fuels, accelerate renewable energy deployment and support private-sector investment in the energy transition.
State Secretary for Energy Elisabeth Zehetner said future progress would depend not only on increasing renewable generation capacity but also on integrating it more effectively into the electricity system. She highlighted the importance of energy storage in improving security of supply, reducing pressure on the grid and ensuring that domestically produced electricity is available when needed.
Burgenland provincial councillor Heinrich Dorner described the project as another important step toward climate neutrality and energy independence, highlighting the region’s long-standing role in renewable energy development and its efforts over recent years to accelerate the energy transition.
