TotalEnergies Launches Six Battery Storage Projects to Strengthen Germany’s Power System

TotalEnergies has announced the launch of six new battery energy storage system (BESS) projects in Germany, reinforcing its strategy to expand an integrated electricity portfolio and support the country’s growing renewable energy capacity.

The projects represent a combined 221 MW of storage capacity, backed by an investment of approximately €160 million, highlighting strong momentum in large-scale battery deployment across Europe. 

Developed by Kyon Energy—a TotalEnergies subsidiary acquired in 2024—the portfolio will primarily utilize next-generation battery systems supplied by Saft, the group’s in-house battery technology specialist. 

Construction began at the end of 2024, with commissioning expected in early 2026. Once operational, the systems will play a key role in enhancing grid flexibility, reducing congestion, and supporting renewable energy integration across Germany’s electricity network. 

The initiative marks a significant milestone in TotalEnergies’ development of battery storage capacity in Europe’s largest power market. The company already has 100 MW of storage under construction in Germany and continues to expand its presence across the full electricity value chain, including generation, trading, and aggregation of clean power. 

Battery storage is increasingly critical for managing the intermittency of renewable energy sources such as wind and solar. By enabling “clean firm power”—a stable and continuous supply of renewable electricity—these systems are expected to improve reliability while maximizing the value of renewable generation assets. 

TotalEnergies’ broader German portfolio includes multi-gigawatt pipelines in solar, wind, and storage, underscoring its ambition to become a leading player in the country’s energy transition. 

Overall, the launch of these six projects reflects growing investment in grid-scale storage as a core component of modern energy systems, supporting the transition toward a more resilient and low-carbon electricity network in Germany.
