"Germany's Largest Battery Storage Facility" Launches Near Leuna

Storing surplus electricity for later use

Battery storage systems can balance out fluctuations in renewable energy: The new storage facility absorbs excess wind and solar power and makes it available again later when demand rises. This is intended to relieve the strain on the power grids and reduce the need to curtail renewable energy plants.

“Large-scale storage systems are the key to this flexibility,” said Schulze. Saxony-Anhalt already generates large amounts of electricity from solar and wind power. With storage, this energy can be made available more readily when it is needed. “This strengthens the security of supply and makes our power grid more stable.”

The storage network consists of five sub-facilities and is connected to several specially constructed substations. According to Münch Energie, construction took about six months. The project was financed entirely by the private sector and without government subsidies.

The region has a long history in the energy sector. Lignite has been mined in the Leipzig area for more than a century; many former open-pit mines have since been shut down and flooded. Company founder Mario Münch described the development of new energy infrastructure as a “very wise continuation of that history.”
