Deploying the Largest BESS in the Czech Republic: From Contract to 400 kV Grid Integration

A case study of the Czech Republic’s largest BESS storage hub (800 MWh), focusing on the technical, operational, and commercial execution of large-scale BESS infrastructure.

• Direct integration into the 400kV transmission grid via a privately owned substation.
• System architecture, high-voltage schematics, and critical infrastructure cyber security across multiple independent project entities.
• Field-tested lessons learned from executing a utility-scale energy storage project.
