OUR PROJECTS FOR
THE ENERGY FUTURE

Planning, building and operating large-scale battery storage systems across Germany

HOW IS A LARGE-SCALE BATTERY STORAGE SYSTEM BUILT?

From the first groundbreaking to commissioning: In our video series, we follow the construction of a large-scale battery storage system step by step—transparent, easy to understand, and straight from real-world practice.
