Allianz Global Investors Buys Majority Stake in German GESI Battery Projects
Allianz Global Investors has acquired a 51 percent stake in battery storage platform GESI. The move initiates a significant investment program for battery projects in Germany.

Allianz Global Investors (AGI) has purchased a 51 percent share in the Green Energy Storage Initiative (GESI), a platform that plans, builds, and operates large-scale battery storage systems. This investment marks a significant commitment to Germany's energy infrastructure.
GESI, founded by Martin A. Schoeller, aims to capitalize on surplus solar and wind energy generated in Germany. "Energy storage saves fossil fuels, makes us independent of imports, and helps make renewable energies capable of providing baseload power," Schoeller stated. The initiative was developed through Schoeller Ventures, a startup incubator within the Schoeller Group.
The partnership with AGI, acting on behalf of Allianz insurance companies, is seen as a strong endorsement of GESI's strategy. "The entry of a leading global investor into energy infrastructure is a major vote of confidence in our concept and the entire team," Schoeller commented.
GESI has confirmed an extensive investment program for battery projects in Germany. The company has secured grid connection commitments for three sites totaling 2.6 gigawatts of capacity, with further projects in development. Potential locations include former nuclear power plant sites that already possess the necessary energy infrastructure.
GESI was established by the Schoeller Group in late 2023. The company is seeking reliable regulatory frameworks and trust in battery storage systems commissioned before August 4, 2029, to mobilize further private capital.
