French energy major TotalEnergies SE has approved the final investment decision for a 100-MW/200-MWh battery energy storage system (BESS) in Germany, the company announced on Wednesday.
The project will involve a total investment of over EUR 75 million (USD 81.3 million). The battery storage facility will be located in Dahlem, North Rhine-Westphalia, and will use lithium-iron-phosphate technology developed by TotalEnergies' battery affiliate, Saft. The facility is scheduled to begin commercial operations in the second half of 2026.
Quadra Energy, a German aggregator of renewable power owned by TotalEnergies, will handle the marketing of the flexibility offered by the battery storage units.
This BESS project is the first to be executed from the portfolio of Kyon Energy, a German battery storage developer that was integrated into TotalEnergies in 2024.
“This investment decision reflects the acceleration of our integrated development in the German electricity market, the largest in Europe,” said Stephane Michel, senior vice president of Gas, Renewables & Power at TotalEnergies.
