Flower Advances 100 MW Internally Developed BESS Project in Hamburg

The project, aimed at entering operation in late 2028, marks a key milestone in Flower’s expansion in Germany and supports the growing role of battery storage in the country.

The announcement comes as the deployment of battery storage in Germany is accelerating, continuing to support the integration of renewable power while stabilizing the electricity system. 

“The Bergedorf project demonstrates our long-term ambition to scale battery storage across Europe and support the stability and affordability of Germany’s energy system. I’d like to extend a big thank you to Bergedorf Municipality, Hamburger Energienetze and all our local partners in making this project a reality” says John Diklev, founder and CEO of Flower.

Since 2023, Flower’s internal asset development team has led a comprehensive development process for the project, including permitting, stakeholder management and grid connection approvals.

“As with all our internally developed projects, the Bergedorf project has been developed in close collaboration with municipalities, landowners and grid operators to ensure it delivers value for both local communities and the broader energy system,” says Annie Olofsson, VP Asset Development at Flower.

Expanding presence in Germany and Europe

Flower recently announced the acquisition of a 63 MW / 257 MWh BESS project in Döllnitz, Saxony-Anhalt. In parallel, the company is advancing several internally developed BESS projects across Germany.

Flower owns four operational BESS sites in its native Sweden (63 MW in total), with three additional, internally developed projects set to be operational in the country by 2026 (70 MW in total). The company is also developing large-scale battery projects in the Netherlands, France and Belgium, building a multi-GWh development pipeline across Europe.
