Commercial Battery Storage
Commercial and industrial battery storage across Queensland and the Australian Capital Territory. Three are operating. The fourth is being built on a live airport terminal.
Project 01
Battery storage on the Port West estate, delivered for Port of Brisbane Pty Ltd under an EPC agreement. Solar runs alongside it across several estate tenancies. The connection is high voltage, which brings Energex into the design: stability modelling, droop curve assessment, protection grading.

| Battery | EVO Power NEO |
| Rating | 1,000 kW / 1,750 kWh |
| Connection | High voltage, assessed with Energex |
| Engineering | PSCAD system stability modelling, droop curve assessment, protection relay grading |
| Delivery | Engineer, procure and construct |
Project 02
1,125 kWh of storage paired with 238 kWp of rooftop solar at the Brisbane International Cruise Terminal, delivered for Port of Brisbane Pty Ltd, sized to carry the terminal through the evening peak and integrated with front of meter monitoring from commissioning.

Project 03 In construction
Rooftop solar and battery storage replacing two standby diesel generators at the Canberra Airport terminal. Built on a live passenger terminal under airside access control, with supervisory monitoring across both solar and storage.
| Status | In construction |

| Client | Canberra Airport |
| Location | Canberra Airport, Australian Capital Territory |
| Battery | Sungrow PowerStack, 18 units |
| Rating | 1,980 kW / 4,050 kWh |
| Solar | 2.696 MWp, 4,280 Trina modules, 21 Sungrow SG110CX inverters |
| Diesel | Two generators removed from the terminal generator room |
| Conditions | Operating terminal, airside access, Evoenergy connection |
Project 04
A standalone Sungrow battery on an embedded network site. It cuts demand in the evening peak and trades into the wholesale market. At 900 kWh it sits squarely in the band the New South Wales commercial rebate is aimed at.
| Status | Complete |
|---|---|
| Location | Strathpine Square, Queensland |
| Battery | Sungrow PowerStack, 4 units |
| Rating | 440 kVA / 900 kWh |
| Configuration | Standalone battery on an embedded network site |
| Operation | Evening peak demand reduction, wholesale and frequency market participation |
| Controls | Site energy management system with external market dispatch |
The battery is the easy part to buy. The connection, the protection design and the fire separation are what decide whether it runs.
Applications, technical studies and negotiation with the distributor, to high voltage where required. Connection conditions determine what the asset is permitted to do, so they are settled before equipment is ordered.
PSCAD modelling of inverter behaviour, droop curve assessment and dynamic response, agreed with the network operator. Larger connections are approved on the model, not on the datasheet.
Relay selection and grading, earthing design and fault study. Discrimination is what keeps a fault local instead of taking out a site.
Harmonic and voltage assessment against the connection limits, measured rather than assumed, so compliance is demonstrable at commissioning.
Separation distances, deflagration venting and a site specific fire assessment, resolved against the final position of the equipment.
Supervisory control across solar and storage, so the asset delivers the outcome it was sized for rather than a default schedule.
All three are in play on every site, in different proportions. Which one dominates is set by the tariff and the load shape, not by the size of the battery. That is why we size from a bill.
Project details are described at a level agreed with each client. Figures shown are technical scope only. Commercial terms are confidential to each contract. Our wider solar record is on the projects page.
No. The New South Wales incentive does not require it, although a project that includes new solar attracts a higher incentive. Two of the four sites here run solar and storage together. Strathpine Square is battery only.
It is set by the load shape and the tariff, not by floor area or by the size of the bill. Two sites with the same annual consumption can need very different systems. The battery calculator sizes from your own demand profile.
An application to the distributor, the technical studies it asks for, and a set of agreed connection conditions. High voltage and larger connections add system stability modelling and protection grading. Those conditions are settled before equipment is ordered, because they govern what the asset is allowed to do.
Queensland and the Australian Capital Territory, for Port of Brisbane, Canberra Airport and Strathpine Square, in sizes from 900 kWh to 4,050 kWh.
Work it out from your own demand profile in about a minute, and see what the New South Wales incentive is worth against it.
