Liberty Parade & Wimpole Crescent Community Battery Installation-Civil & Electrical Infrastructure
Zinfra & PSD Energy
Overview
Zinfra initially engaged Tradetech Services Australia to deliver underground electrical infrastructure within the road reserve, for the Liberty Parade Community Battery Project. Following the successful completion of this stage, PSD Energy subsequently engaged Tradetech to undertake all civil and electrical preparation works within the site boundary, encompassing excavation, conduit and pit installation, slab preparation, and site reinstatement for the battery installation compound.
This dual-client engagement demonstrates Tradetech's capability to seamlessly coordinate with multiple stakeholders while maintaining compliance with Jemena's standards, VEDN requirements, and local council permits.
Scope of Works
Under the direction of Jemena/Zinfra, TSA completed
the underground installation of electrical infrastructure
to support the community battery system, including:
- Supply and installation of new underground conduits and a 240 mm² 4-core LV XLPE mains cable between the existing pillar (A096425) and the new Battery Main Switchboard (MSB).
- Coordination with Jemena and the local council for road occupancy and traffic management approvals.
- All works carried out in strict accordance with AS/NZS 2053, VEDN, and Jemena network specifications.
- Execution of non-destructive digging (NDD) to confirm service locations before trenching.
- Installation of compliant LV earthing (CMEN system) and traffolyte labelling to Jemena's SP14/100/64 Type 8 standard.
Key Civil and Building Construction Activities
PSD Energy – Boundary and Civil Works
After completing the road reserve installation, PSD Energy directly engaged Tradetech to deliver all site works within the battery compound area. The works included:
- Establishing temporary fencing, signage, and traffic management to control vehicle and pedestrian access.
- Site excavation (approx. 7 m × 2.56 m × 0.15 m) and subgrade compaction to 98% density, verified by NATA-accredited testing.
- Installation of communications and electrical conduits, including 2 × 50 mm comms and 2 × 80 mm HD conduits, with correct depth and radius per PSD and Jemena specifications.
- Placement of P5 electrical pits and connection to existing infrastructure.
- Preparation and levelling of the precast concrete slab foundation, including moisture barrier membrane and bedding layer.
- Final site reinstatement and handover are ready for battery installation.
Complex Stakeholder Engagement
Outcome and Client Feedback
Tradetech’s collaborative approach, technical precision, and strong safety culture ensured seamless delivery across both scopes. PSD Energy has since engaged Tradetech for two other separate community battery projects, each delivered to the highest quality standards. PSD has noted that the quality of workmanship was the best they had encountered to date, reinforcing Tradetech’s reputation for excellence in utility infrastructure delivery.
Key Capabilities Demonstrated
- End-to-end project delivery for civil and electrical infrastructure supporting energy storage systems.
- Proven ability to coordinate multi-client, multi-stakeholder projects under utility and council governance.
- Compliance with AS/NZS, VEDN, Jemena, and WorkSafe standards.
- High-quality workmanship verified through independent compaction and electrical testing.
- Strong record of repeat engagement with PSD Energy based on client satisfaction and trust.
Summary
This project highlights Tradetech’s integrated capability in civil, electrical, and project coordination disciplines, from public road reserve works through to private boundary installations. The successful outcomes for both Zinfra and PSD Energy demonstrate Tradetech’s capacity to deliver turnkey infrastructure solutions for Australia’s growing community battery network.
