ADS-TEC Energy and Salzburg AG have announced the technical prequalification of the ChargePost fast charging system for Austria’s ancillary services market. This development allows the battery-based charging system to participate in the Austrian energy market while simultaneously serving electric vehicle (EV) drivers. Salzburg AG has integrated the units into its virtual power plant to actively support grid stability.
Highlights
- ChargePost achieves technical prequalification for the Austrian ancillary services market.
- System integrates into Salzburg AG’s virtual power plant for frequency stabilization.
- Unit delivers 300 kW ultra-fast charging with 201 kWh battery capacity.
- Salzburg AG commits to deploying 20 additional ChargePost systems.
Dual-Purpose Infrastructure
The successful prequalification confirms that ChargePost can execute short-term power adjustments necessary for stabilizing grid frequency. This capability introduces a new category of infrastructure that extends beyond traditional EV charging. By functioning as a grid asset, the system provides added value within decentralized energy networks.
Salzburg AG’s integration of ChargePost into its virtual power plant demonstrates a practical application of bidirectional storage. The system balances demand by buffering energy from the grid and releasing it during peak usage or frequency deviations. This dual-use model addresses both the growing demand for EV charging and the need for grid resilience.
Technical Specifications and Capabilities
The ChargePost system is designed to operate on standard low-voltage grids while delivering high-performance output. It combines ultra-fast DC charging capabilities with significant onboard storage. The architecture allows for flexible installation in areas with limited grid capacity.
Key System Features:
- Ultra-fast Charging: Delivers up to 300 kW of power to EVs.
- Battery Capacity: Equipped with 201 kWh of battery storage.
- Bidirectional Storage: Supports intelligent energy management and grid services.
- Peak Shaving: Reduces demand spikes to lower grid connection costs.
These technical attributes enable the system to maintain stable operations and full-power charging regardless of immediate grid fluctuations.
Strategic Expansion and Industry Impact
Following the successful prequalification, Salzburg AG has secured a tender for 20 additional ChargePost systems. This expansion underscores the viability of battery-buffered charging as a scalable solution for utilities. The partnership highlights a shift toward infrastructure that serves multiple roles in the energy ecosystem.
Thomas Speidel, CEO of ADS-TEC Energy, noted that fast charging must evolve beyond a cost center to accelerate growth. He emphasized that intelligent buffering enables new flexibility in infrastructure operations. The collaboration validates that high-power charging can effectively coexist with and support grid stability objectives.
Market Implications
The project represents a milestone for battery-integrated charging technology. Ancillary services were traditionally the domain of large-scale, standalone battery storage systems. ChargePost’s ability to meet these strict criteria in a compact form factor opens new revenue streams for operators. This multi-use approach offers a replicable model for other regions facing similar grid constraints.
