TotalEnergies: €500 Million Partnership With AllianzGI For German Battery Storage Portfolio

By Amit Chowdhry • Mar 4, 2026

TotalEnergies has signed an agreement with Allianz Global Investors for the sale of a 50% stake in a portfolio of 11 battery storage projects currently under construction in Germany, representing a total investment of €500 million.

The portfolio will deliver a combined capacity of 789 MW and 1,628 MWh, forming a major grid-scale storage platform designed to support the country’s expanding renewable energy system. The partners expect the projects to be fully operational by 2028, with around 70% of the capital structure financed through debt.

The battery storage projects were developed by Kyon Energy, a TotalEnergies subsidiary, and will be deployed across multiple locations in Germany. Most of the projects will utilize next-generation batteries supplied by Saft, another subsidiary of TotalEnergies specializing in advanced battery technologies. TotalEnergies will remain the operator of the assets following the transaction.

The investment reflects a broader push to build flexible energy infrastructure capable of balancing intermittent renewable generation. Battery storage systems can help reduce grid congestion and provide the flexibility required as Germany rapidly expands wind and solar capacity.

For TotalEnergies, the partnership supports its integrated power strategy and enables the company to recycle capital while continuing to expand its electricity platform in Europe’s largest power market. Germany remains a key focus for the company’s electricity strategy, where it is developing renewable generation, storage capacity and power trading capabilities.

Allianz Global Investors said the deal represents its first direct equity investment in a portfolio of battery storage projects, strengthening its exposure to infrastructure supporting the energy transition.

The completion of the transaction remains subject to customary approvals and conditions.
