Technology selected for performance, safety and uptime.
ROCAS integrates battery, PCS, MV/HV, EMS and thermal-management technologies as one plant architecture, with immersion cooling positioned as a key differentiator for selected storage applications.
Direct thermal management at cell level.
ROCAS actively promotes immersion-cooled BESS technology as an advanced alternative to conventional air-cooled and cold-plate liquid-cooled battery systems. In an immersion architecture, battery cells are directly surrounded by a dielectric coolant, providing highly uniform thermal management.
This matters most where high utilisation, thermal consistency and system availability have a direct commercial effect. Downtime and safety failures mean less revenue and more costs.
Cold-plate liquid cooling
Established architecture with broad utility-scale market adoption and supplier coverage.
- Proven service ecosystem
- Competitive system pricing
- Familiar maintenance model
- Suitable for standard deployment profiles
Immersion cooling
Cells are directly surrounded by a dielectric coolant, increasing thermal contact and reducing temperature gradients inside the battery system.
- Highly uniform thermal environment
- Direct heat transfer from the cell surface
- Relevant for intensive cycling and harsh environments
- Current catalog includes 10,000- and 15,000-cycle manufacturer-rated configurations
The battery container is only one layer.
Plant performance depends on coordinated behaviour from the cell through the point of connection.
Battery & BMS
Tier 1 LFP cells, rack-level monitoring, central BMS, diagnostics and safety logic.
PCS & MV
Grid-forming-capable power conversion, MV skids, transformers, switchgear and protection.
EMS & SCADA
ROCAS-integrated control architecture, dispatch interfaces, cybersecurity and market coordination.
Grid integration
Studies, PPC, metering, communications, protection settings, energisation and grid-code testing.
Bankability and cybersecurity are design inputs.
For European projects, technology selection is aligned with applicable grid-code, cybersecurity, communications and investor bankability requirements. PCS, EMS and MV architecture are specified project by project.
See the current ROCAS BESS product families.
Utility containers, C&I all-in-one systems, hybrid ESS and MV skids are available in the September 2026 catalog.
