Industry
Utilities
Utility-scale storage with grid-services capabilities and bankable documentation.
Problem
Why this matters.
Utilities need flexibility, capacity, and renewable firming with strict documentation and reliability standards.
Utility planners buy against a system curve, not a site curve: evening ramps steepening as solar penetration grows, capacity shortfalls concentrated in a few hundred hours, and renewable output that needs firming before it can be counted on. Storage is procured as infrastructure — which means documentation, standards compliance, and long-term service matter as much as the cell chemistry.
Navvion Approach
How we deliver results.
Architecture
How the system fits together.
Rows of containerized blocks connect through medium-voltage transformers to the substation bus, dispatched as one plant over SCADA and IEC 61850. The design scales by adding containers, not redesigning the plant.
Simplified one-line diagram. Final architecture is engineered per site.
Products Used
Navvion systems for this solution.
The 5 MWh liquid-cooled Navvion Gamma is the standard fleet block for transmission-connected plants; the 3.3 MWh all-in-one Navvion Delta serves distribution-level and substation-adjacent projects. Navvion Fleet APM operates them as one asset with remote diagnostics.

Economics
What the payback looks like.
| Basis | Bankable, standards-tested infrastructure |
| Fleet building block | 5 MWh / 0.5P liquid-cooled container |
| Delivery | Factory-tested, single-unit shipment |
| Fleet sizing | Per interconnection study |
| Installed cost | Tender-specific |
| Revenue stack | Capacity + ancillary services + renewable firming |
| Simple payback | Modeled per RFP |

Common questions.
What certifications back the utility fleet?
IEC 62619, IEC 62477, IEC 63056, IEC 61000 and UN38.3 transport — full type-test documentation is provided with the bid package.
How do you handle augmentation over the plant's life?
The plant is laid out with augmentation bays and DC headroom from day one, so capacity can be restored or grown by adding containers on the existing design.
Can the plant meet our grid-code response requirements?
Response curves are configured and validated against your grid code during commissioning, with IEC 61850 telemetry into your SCADA.
