Originals and visionaries

In the 90s, we couldn't have known how our path would ultimately turn out. But we had a hunch, a clear goal, the right ideas and the brains to mould all of this from a simple commitment into a company. One that keeps the environment AND people in mind. Because - and this is our conviction - only a healthy (working) environment can give rise to projects for a healthy environment.

After all these years, the time has now come for the next generation to take responsibility. Joachim Payr is handing over the reins to his two daughters Alina and Esther, who will join the company as managing partners on 1 January 2026 in addition to their project management duties and will continue to develop the company together with Gerhard Steindl. This combines experience with new perspectives and the energy of a generation that not only wants to shape the future, but also actively protect it.

The history of EWS

1994
The beginning of a vision
The founding of our company laid the groundwork for a success story in renewable energy and climate protection.
2004
A home for innovation
Our headquarters in Munderfing, Upper Austria, opened – a major step in expanding our activities and further professionalising the company.
2008
Looking beyond borders
The start of international expansion, focusing on south-eastern and eastern Europe. New markets were opened, strategic partnerships formed and our network expanded beyond national borders.
2012
Growth at the Munderfing site
The expansion of our Munderfing site created new jobs – a clear commitment to the region and to sustainable growth.
2019
Solar power added to the portfolio
By entering the photovoltaic sector, we broadened our solar business and set another milestone in driving the energy transition. With the development of our innovative agri-PV solution, the EWS Sonnenfeld, we’ve made the forward-looking combination of energy production, agriculture and biodiversity a reality. 
2022
Expertise for the future
In Parndorf (Burgenland), we opened our competence centre for wind energy and agri-photovoltaics – a hub for research, development and new ideas. At the same time, we launched the EWS Sonnenfeld research centre in Bruck an der Leitha (Lower Austria), where we’re developing the solutions of tomorrow.
2023
Strong partner for EPC solutions
Since 2023, we’ve been offering comprehensive solutions as a general contractor for large-scale projects, primarily in the PV sector – with competence, efficiency, safety and a clear focus on the future.
2024
Presence in the capital
With the opening of our Vienna office, we now have a presence in the federal capital – closer to our partners, projects and political decision-makers.
2025
The next step - smart grids and storage solutions
Since 2025, we’ve also been developing cost-effective, grid-friendly storage solutions – from battery systems to hybrid set-ups combining wind and solar power. This allows us to ensure grid stability, boost efficiency and make renewable energy more predictable and accessible than ever before.
2026
Stable into the future - a new generation, a breath of fresh air
A new era is dawning at EWS! A good three decades after EWS was founded, we are reorganising our management: On 1 January 2026, Joachim Payr, one of the EWS company founders, handed over his management to his two daughters Esther and Alina Mirwald, who will now run the company together with Gerhard Steindl.
