The Scale Energy team in Berlin

The people behind Scale Energy.

Three managing directors, one team in Berlin.

The three founders combine experience from the energy industry, engineering and infrastructure financing. Founded in Berlin in early 2024, Scale Energy develops, builds and operates battery storage for industrial businesses, solar and wind parks and open land in Germany and Austria — together with municipal utilities and grid operators.

At Scale Energy, we see battery storage not just as an asset — but as infrastructure for a smarter energy economy.

Frequently asked questions.

Who is behind Scale Energy?

+

Scale Energy GmbH, based in Berlin, founded in 2024 and led by three managing directors. We have worked with manufacturing businesses from day one and deliver several projects together with municipal utilities and regional grid operators.

Where does Scale Energy operate?

In Germany and Austria. Our headquarters are in Berlin; we deliver projects nationwide and in Austria.

Who finances the storage projects?

Industrial businesses buy or lease the storage system; the leasing rate is typically below the monthly savings. For open-land projects, Scale Energy invests itself and pays a long-term lease.

Does Scale Energy operate the storage systems itself?

Yes. We handle 24/7 monitoring, maintenance and power-market trading across the entire project lifetime. The operating risk is ours.
