Swiss energy company Alpiq is entering the German battery storage market with a 370MW project pipeline for battery energy storage systems (BESS) in the regions of Brandenburg and Saxony-Anhalt. The projects are scheduled to reach ready-to-build status in 2026, marking a key step in the company’s European flexibility strategy.
The BESS pipeline has been developed in cooperation with SPP Development, a German project developer with more than 15 years of market experience. Alpiq is contributing its expertise in operating flexible power assets, its financial resources and its long-term strategic focus on the German BESS market, while SPP Development brings regional knowledge and technical capability.

The companies aim to support Germany’s growing need for short-term energy storage and grid stabilisation as wind and solar capacity continues to expand. By providing fast-response storage, the planned BESS plants are intended to help integrate more renewable electricity into the system and strengthen security of supply.
Alpiq has identified flexibility as a strategic business pillar and is building on more than a century of experience in operating hydropower and thermal plants.
The German projects follow several recent milestones in battery storage: the commissioning of a 30MW BESS in Valkeakoski, Finland, in October; a tolling agreement for the 103.5MW Schuby battery in Schleswig-Holstein at the end of November; the acquisition of a 125MW BESS project in Haapajärvi, Finland, due to start operation in mid-2027; and the development of a 100MW BESS in La Corne-en-Vexin, France, planned for early 2027. In Switzerland, Alpiq has been marketing third-party batteries since 2018 and currently manages a 50MW portfolio.
According to Alpiq, the investment in the German BESS portfolio is intended to reinforce its role in the energy transition and support the build-out of a more flexible, renewable-based power system in Europe.
