Energy infrastructure in Germany is set for a new round of reinforcement after TotalEnergies agreed to sell half of its stake in eleven battery storage projects to Allianz Global Investors (AllianzGI) in a transaction valued at approximately €500m (US$580m).
The projects, developed by TotalEnergies’ subsidiary Kyon Energy, represent 789 MW of power capacity and 1,628 MWh of energy storage. All eleven sites are scheduled to be operational by 2028, helping strengthen the country’s electricity system as renewable generation expands across Germany.
Most of the facilities will use next-generation battery technology supplied by Saft, another unit within TotalEnergies. While AllianzGI will own half of the portfolio, TotalEnergies will continue managing day-to-day operations of the storage network.
The partnership reflects growing pressure on European grids as wind and solar installations accelerate. Battery storage is increasingly seen as a tool to reduce congestion, smooth intermittent renewable output, and provide fast-response flexibility when weather-driven generation fluctuates.
For TotalEnergies, the sale supports a broader capital recycling strategy within its integrated European power business. The company has been expanding activities across renewable development, electricity trading, and low-carbon supply, including long-term power agreements such as a 200 MW supply contract with Airbus SE.
For Allianz Global Investors, the investment marks its first direct equity position in a battery storage portfolio, adding to a transition-focused asset base built over two decades that already spans wind projects and emerging hydrogen infrastructure.
Industry observers say the deal illustrates how institutional capital is becoming a larger player in the behind-the-meter and grid-support segments of the energy transition.
