In an Industry First, Salzburg AG Uses ADS-TEC Energy’s ChargePost to Support Both Ultra-Fast EV Charging and Grid Stability
- ChargePost enables ultra-fast EV charging and provides battery storage for grid support
- Prequalification allows participation in Austria’s ancillary services market
- Deployment showcases economic viability of multi-use charging without costly grid upgrades
- Salzburg AG plans to extend deployment with 20 additional ChargePost systems.

The prequalification confirms that ChargePost is capable of providing short-term power adjustments to help stabilize grid frequency. This represents a new category of fast charging infrastructure: one that not only serves electric vehicles but adds value in an increasingly flexible and decentralized energy system.
ChargePost combines ultra-fast DC charging of up to 300 kW with up to 201 kWh of battery capacity, even when connected to the standard low-voltage grid. Its bidirectional storage and intelligent energy management enable:
- Peak shaving capabilities
- Reduced grid connection costs
- Stable operation and full-power EV charging at any time
These capabilities illustrate how battery-integrated fast charging can operate efficiently and reliably, even in areas with limited local grid capacity.
At a joint event in
Thomas Speidel said, “To accelerate growth, fast charging has to evolve from being a cost center. With intelligent buffering and stable grid behavior, systems like ChargePost open up new flexibility in the operation of charging infrastructure. Our work with Salzburg AG shows how high-power charging and grid stability can go hand in hand.”
Further expansion of the collaboration
ADS-TEC Energy has also won a tender from Salzburg AG for 20 additional ChargePost systems. This commitment demonstrates the importance of the two companies' strategic partnership as they continue to build-out battery-supported fast charging infrastructure in the region.
A technology milestone that delivers new market opportunities
ChargePost’s prequalification demonstrates that it meets the criteria required to provide ancillary services – a capability traditionally reserved for standalone, large-scale battery storage systems. This compact multi-use architecture enables fast charging and grid support in a single system, offering utilities and charging operators a scalable approach that can be replicated across additional regions and markets.
