Driving the energy transition across borders
Together with our partners, we are taking the energy transition beyond Austria's borders. Drawing on more than 25 years of experience, we make renewable energy expansion efficient and reliable.
About PÜSPÖK International
By combining PÜSPÖK's decades of market leadership with Stromstärke's technical delivery capabilities, we build high-performance renewable energy infrastructure – from initial concept to long-term operation.
PÜSPÖK is a family-owned company that has been passionate about renewable energy for more than 25 years. Our journey began in Burgenland, Austria, where we developed and built one of the region's first wind farms. Today, PÜSPÖK is one of Austria's leading wind power operators. What started as a vision has become a mission: to accelerate the energy transition and create a future powered entirely by renewable energy.
The Stromstärke team is dedicated to delivering renewable energy projects across Europe. From the initial idea through to commercial operation, Stromstärke supports customers and partners with extensive technical expertise and helps them achieve their goals. Stromstärke also develops its own wind and PV projects in Europe.
Our mission
Driving renewable energy beyond borders:
For many years, we have been expanding our expertise internationally. While our roots remain firmly in Austria, we know that the energy transition requires international collaboration.
Stromstärke shares this vision – so we joined forces, combining our expertise and our proven international track record in renewable energy.
Through our international projects, we share our experience in wind power, photovoltaics and battery storage – and learn from the communities we work with. By building partnerships based on trust, mutual benefit and sustainability, we bring our values – reliability, innovation and environmental stewardship – to new markets across Europe.
Together, we’re building a cleaner, brighter future.
