We believe that energy belongs to everyone.
No matter when or where.
Because energy means freedom.
The freedom to create, to develop, to research.
Which is to say, everything that moves us forward.
So it has to be accessible at all times.
Independent of fossil fuels.
Independent of weather conditions.
Independent of politics.
Our ideas, our technologies and our partners
are helping to drive the energy transition by letting
everyone choose to live sustainably.
Thanks to us, they have the choice. They are
free to go green.
What does “free to go green” mean exactly, and what does freedom have to do with our energy storage solutions? Find out in our company film:
TESVOLT is a leading German provider of battery storage systems for commercial, industrial, and large-scale energy projects . We are driving the energy transition forward and enabling companies to use energy freely and decentrally, as well as to trade electricity profitably.
Founded in 2014 by Daniel Hannemann and Simon Schandert, TESVOLT has since successfully positioned itself in the market for battery storage solutions. In 2022, finance expert Philipp Koecke joined the Board of Directors. From the very beginning, our goal at TESVOLT has been to create a world in which everyone can use green energy autonomously. With innovative technology, we develop energy solutions that enable freedom from fossil fuels and economic constraints. TESVOLT has already received numerous awards, including the German Entrepreneur Award and the Top 100 Award twice in a row as Germany’s most innovative company.
The group includes the subsidiary TESVOLT ENERGY GmbH, which enables profitable energy trading for commerce and industry, and the joint venture TESVOLT OCEAN GmbH, which provides maritime shipping companies with high-performance battery storage solutions for challenging conditions at sea.

As a system integrator , TESVOLT combines its own control software with certified storage hardware from leading manufacturers to create high‑performance complete systems. We support our customers throughout the entire lifecycle of their storage project – from planning and construction to operation and monitoring, all the way through to the marketing of electricity from storage systems via TESVOLT’s subsidiary, TESVOLT Energy. At present, TESVOLT is the only company on the market that offers battery storage systems, project planning, and electricity marketing from a single source.
We excel with innovative energy solutions that are precisely tailored to the needs of industry and commerce and enable a wide range of different applications .
With more than 6,000 projects worldwide, TESVOLT storage systems are already helping to make the world better, greener, and more independent. And the trend is rising. Because TESVOLT is an innovator that, with its agile structure, can respond to market changes flexibly, quickly, and effectively.

We have enormous storage capacities in Europe, and we want to makes these resources accessible without limitation. Because we have the potential to create freedom. The freedom that awaits at the end of our green revolution. But this energy revolution won’t just happen on its own. It will take all of us. So we are seizing opportunities and working with partners and customers who want to be part of this “greenolution”. We may not have been around for long, but with enough allies to carry our ideals forward we can achieve our goal of enabling affordable green energy – anywhere and at any time.
The market for energy storage systems that can be connected to renewable energy sources is enormous. And TESVOLT technology is leading the way.

Our technological solutions, with their intelligent networking of generation, consumption and storage, make energy autonomy a reality. Because no matter what kind of energy issue you have, we have the right solution.

With over 6,000 projects realised to date, we’ve proven that “green” industry is possible. And every new TESVOLT battery storage system installed is another step closer to our destination on our journey to the energy transition.
