We stand where your investment is built.
ECO-PARK's management accompanies every project personally – from the foundation through installation to commissioning.
The company
A Germany-wide network of decentralised storage.
ECO-PARK is building a network of decentralised battery storage across Germany. Suitable sites – storage, commercial or parking areas – are used on a long-term basis, preferably in commercial and industrial zones with suitable grid connections.
Several storage units are installed at each site and integrated into the ECO-PARK concept. The compact design allows efficient implementation; whether a building permit is required is checked individually for each site.

Business administration and tax concepts
