Energy transition? It’s our business!

Energiequelle GmbH has been active in the renewable energies market since 1997. With more than 260 staff and over 750 installed wind turbines, we are one of the industry’s leading companies – passionate, bold, and innovative.

An experienced full-service provider
We have been implementing renewable energy projects for more than 20 years, developing, constructing and operating wind energy and photovoltaic plants, transformer stations and energy storage systems. We are also working on innovative energy supply solutions, managing repowering projects for old plants and selling sustainably produced electricity to end customers via our subsidiary eqSTROM.

We manage the electrical, technical, and commercial aspects of over 730 power production facilities. Our customers attest to our excellent customer service performance and praise our high level of customer friendliness, accessibility, and continuing reliability.

In terms of funding and sales, we maintain long-term, collaborative relationships with plant manufacturers, credit institutions and investors, the result of which are innovative and bespoke funding solutions for our national and international customers.

Collaboration and project purchasing  
We are always on the lookout for collaboration partners with whom we can pool our skills and advance projects together. Our services also include project purchasing – we take on projects at every stage, in Germany and abroad.

New business area for innovative energy concepts
Our business development colleagues are currently working on innovative future technologies, such as self-supply electricity solutions for industrial and commercial customers in the electricity, heating, and mobility sectors. We are also conducting research into Power-to-X projects and are currently developing a power generation reference constant for the generation, use and storage of hydrogen in the Lausitz region.

Internationally active
Our headquarters are in Kallinchen near Berlin and we also operate out of a total of 15 locations in Germany, France and Finland. The first project in Finland was launched this year; another one is under construction and an additional 800 MW are in the pipeline. We have already built over 100 wind turbines in France and are very well networked in the French market through our subsidiary P&T Technologie. We wish to gain a foothold in two further markets by 2025 and are, therefore, steadily driving forward our corporate growth.

In addition to Feldheim, the first energy self-sufficient village in Germany, we built a 10 MW energy storage facility in collaboration with Enercon and played a major role in the implementation of the "Green EuroSpeedway Lausitz". We have now connected a total of over 750 wind turbines with a rated output of over 1400 MW to the grid. 

Personal, fair, and down-to-earth
Our company philosophy has not changed since 1997: in spite of the enormous growth we have experienced, we are still a family-run business and cultivate personal relationships, both in-house and with our partners. It is important to us to work on an equal footing in a mutually honest and fair manner and to be reliable at all times. This is what connects us in our common mission.
