AllianzGI Invests in Battery Storage Platform GESI

April 23, 2026 | The asset management company Allianz Global Investors (AllianzGI) announced today in a press release that it has “acquired a 51% stake in the battery storage platform Green Energy Storage Initiative (GESI) on behalf of Allianz insurance companies.”

Through this investment, Allianz is expanding its “engagement in the field of large-scale battery storage” and contributing, among other things, to the stabilization and resilience of the energy system. Battery storage systems are considered a key component of the energy transition, as they can reduce grid bottlenecks, efficiently integrate renewable energy, and provide short-term flexibility.

“For a successful and affordable energy transition, Germany urgently needs additional storage capacity,” says GESI CEO Walter Raizner. “With Allianz as an experienced and reputable partner, we are now ideally positioned to make a significant contribution to the transformation of the German energy system—supporting climate protection and an independent, sustainable energy supply.”

“Currently, green electricity worth billions of euros is lost every year because wind and solar plants have to be curtailed or shut down,” says GESI COO Jens Michael Wegmann. “Allianz’s commitment shows that energy storage is a key lever to better utilize the potential of renewables, reduce system costs, increase security of supply, and improve the overall economic efficiency of the energy system.”
