TotalEnergies has put in place a strategic partnership with Allianz Global Investors ( AllianzGI ) via the sale of a 50% stake in a portfolio of 11 battery energy storage system ( BESS ) projects in Germany with a total capacity of 789 megawatts. 

With this agreement, the partners will deliver an investment of €500 million ( US$581.44 million ) in critical energy infrastructure for Germany.

The projects, developed by Kyon Energy, a subsidiary of TotalEnergies specializing in large-scale BESS projects, will be operational by 2028, with TotalEnergies remaining the operator of all the assets. Watson Farley & Williams advised TotalEnergies. 

Most of the projects will deploy next‑generation battery technology provided by Saft, another TotalEnergies subsidiary and a global leader in advanced battery solutions. 

The project are expected to directly contribute to the resilience of the German power system by reducing grid congestion and providing the flexibility needed to support the rapid growth of renewable energy in the country.
