Flower Advances Internally Developed BESS Project in Saarland, Germany

The project, aimed at entering operation in 2027, is Flower’s second internally developed project in Germany to reach the ready-to-build stage, following its recently announced 100 MW / 400 MWh BESS project in Bergedorf, Hamburg.

As the deployment of battery storage continues to accelerate, the project will support the integration of renewable energy while contributing to the stability of the electricity system.

“This is another testament to our ability to scale battery storage across Europe and support the stability and affordability of Germany’s energy system. We are very grateful for the support of Gersheim municipality, Pfalzwerke Netz AG, and all our other local partners who have helped bring this project to life,” says John Diklev, founder and CEO of Flower.

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

“As with all our internally developed projects, the Gersheim 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.

With two ready-to-build projects in its German development pipeline, alongside the recent acquisition of a 63 MW / 257 MWh BESS project in Döllnitz, Saxony-Anhalt, Flower’s confirmed battery portfolio in Germany now totals 173 MW / 677 MWh.

In its native Sweden, Flower owns four operational BESS sites (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.
