TotalEnergies’ Kyon starts installing 98-MW/215-MWh batteries in Germany

• Kyon Energy has begun building three German battery systems totaling 98 MW/215 MWh, adding multi-hour flexibility to support renewables and evening peaks.

Kyon Energy, a German battery developer majority owned by TotalEnergies, has started installing three battery energy storage systems (BESS) with a combined capacity of 98 MW/215 MWh across Germany. The projects add multi-hour flexibility that will soak up surplus wind and solar and discharge through evening peaks, while providing sub-second frequency support to stabilize a grid increasingly dominated by inverter-based resources.

The engineering follows Europe’s best practice: containerized lithium-ion units arranged in sectionalized arrays with fire-suppression zones, off-gas detection, and robust thermal management. Grid-forming inverters will supply synthetic inertia, frequency-watt response, and voltage control in line with evolving TSO requirements. A unified SCADA platform will co-optimize energy arbitrage across day-ahead and intraday markets with ancillary services, while managing state of charge to ensure availability during high-value windows.

Site selection centers on deliverability—proximity to strong substations, clear access, and manageable environmental constraints. Community measures include acoustic treatments, traffic management during construction, landscaped buffers, and emergency-response coordination with local fire services. End-of-life provisions and recycling pathways are embedded to meet lender and municipal expectations.

Commercially, diversified revenues are the hedge: energy spreads, balancing-market services, and potential capacity-like products. As Germany’s “duck curve” deepens, two-hour-plus duration boosts capture rates and curbs curtailment, converting intermittent megawatt-hours into dependable evening megawatts.

For TotalEnergies, Kyon’s rollout strengthens a European storage platform that complements its generation and retail footprints. For the system operator and consumers, it means fewer price spikes and better use of every installed megawatt of renewables—exactly the flexibility the Energiewende now prizes most.
