Energy for the future: Our contribution to Hamburg’s largest battery storage facility
The go-ahead has been given for Hamburg’s largest battery storage facility. Our branch in Soest has drawn up the planning application, the drainage plans and the technical plans in accordance with the AwSV for this project. It is a project that not only contributes to the energy transition but also overcomes technical challenges.
Hamburg’s largest battery storage facility – part of a future-proof energy infrastructure
The energy transition is presenting our electricity system with new challenges. A key factor here is the expansion of renewable energy, which is making the electricity supply increasingly dependent on weather conditions and the time of day. At the same time, electricity demand is rising significantly due to the electrification of transport, industry and buildings. Innovative solutions are needed to balance out these fluctuations and ensure a stable supply.
Battery energy storage systems (BESS) are a key component. Acting as a ‘buffer’ in the electricity grid, they store surplus energy from renewable sources and release it when required. In this way, they contribute to grid stability and security of supply, and promote the integration of renewable energy – whether at local or supra-regional level.
The Swedish company Flower Infrastructure Technologies AB (Flower) specialises in the development and operation of such energy storage systems. Its aim is to create a stable, climate-friendly and economically viable electricity system. Its approach combines the deployment of battery storage systems with an advanced optimisation platform that intelligently links energy generation and consumption.

Technical aspects of the project
The location of the new battery storage facility – Hamburg-Bergedorf – was carefully selected by Flower on the basis of its grid capacity. With an impressive capacity of 100 MW and a storage capacity of 400 MWh, it will help to ensure the region’s energy supply is fit for the future.
The planned facilities include, amongst other things:
- A high-voltage transformer
- 20 power conversion systems comprising medium-voltage switchgear, transformers and inverters
- 80 battery containers
- Two transformers for own consumption
These components form the backbone of the new storage facility, which will actively support Germany’s climate and energy targets in future.
Our contribution – from planning to implementation
On behalf of Flower Infrastructure Technologies AB, we initiated the planning application for this pioneering project. We also carried out the drainage design and the specialist planning required under the Ordinance on Facilities for the Handling of Substances Hazardous to Water (AwSV). We are particularly proud that our work enabled the project to proceed swiftly and that, working in partnership with Flower and the relevant authorities, we were able to secure planning permission.
The significance of this project was highlighted at the ground-breaking ceremony, including by the Deputy Mayor, Ms Fegebank. The ARD video, „Spatenstich für Hamburgs größten Batteriespeicher“, provides an insight.
