The portfolio will deliver nearly 800 MW of battery storage capacity—789 MW and 1,628 MWh in total


Energy giant TotalEnergies has struck a major deal with Allianz Global Investors to accelerate battery storage development in Germany, selling a 50% stake in a portfolio of 11 battery projects in a transaction expected to drive €500 million of investment into the country’s power infrastructure.
 
The portfolio will deliver nearly 800 MW of battery storage capacity—789 MW and 1,628 MWh in total—aimed at strengthening Germany’s electricity system as renewable generation expands. Around 70% of the investment will be financed through debt.
 
The 11 projects have been developed by Kyon Energy and are spread across Germany. All are expected to be operational by 2028.
 
Most of the systems will use next-generation batteries supplied by Saft, a global specialist in high-tech battery technology. TotalEnergies will continue to operate the assets once they are completed.
 
The partners say the storage projects will help stabilise the German grid by easing congestion and providing the flexibility needed to support the country’s rapidly growing renewable energy sector.
 
Germany remains a strategic market for TotalEnergies, where the company operates across the full power value chain—from renewable generation such as wind and solar to battery storage, electricity trading and aggregation that enables round-the-clock low-carbon power supply.
 
“We are delighted to welcome Allianz, a first-class partner in Germany, as a shareholder in 11 of our battery storage projects, representing a total capacity of nearly 800 MW. In line with our business model, this transaction enables us to optimize our capital allocation in our integrated power activities and helps improve the sector’s profitability. 
 
"This operation, strengthen our development momentum in Germany, Europe’s largest power market, where we are deploying our clean firm power strategy, as illustrated by the 200 MW PPA signed with Airbus recently,” said Stéphane Michel, President, Gas, Renewables & Power at TotalEnergies.
 
“The shift to cleaner energy depends on strong infrastructure. This investment marks Allianz’s first direct equity commitment to a portfolio of battery storage projects. As a pioneer in energy transition investing for more than 20 years with a portfolio spanning wind and solar farms, green hydrogen platforms, and an electricity interconnector, we are very delighted to partner with Total Energies on this important project in one of our home markets, Germany. 
 
"These eleven projects across Germany with a capacity of 789 MW upon completion will help reinforce the country’s energy resilience, accelerate the energy transition, and deliver long-term value for our clients,” commented Édouard Jozan of Allianz Global Investors.
