• TEC-C scope: BESS balance-of-plant installation works and complete EPC delivery of the 220/33kV substation

Approach

TEC-C delivered balance-of-plant installation works for the 100MW/200MWh Terang BESS and completed EPC delivery of the new 120MVA 220/33kV substation to enable connection into the AusNet Transmission network.

To maintain programme certainty through construction and commissioning, TEC-C coordinated delivery across multiple work fronts, aligning installation sequencing, logistics and subcontractor activities. In parallel, TEC-C supported critical interface requirements including the AEMO 5.3.9 connection pathway for a new inverter model and planning compliance updates for the final layout, reducing approval-driven rework and avoiding delays to commissioning activities.

The project required careful planning and sequencing due to a tight site footprint, a physically congested connection environment, and noise and layout constraints that needed to be managed without compromising programme or safety outcomes.

TEC-C’s delivery approach was designed to keep the project advancing safely and efficiently, including early cable installation where practical, disciplined workface coordination, and construction sequencing that supported continuous progress even within a very constrained footprint.

Outcome: Works were coordinated across the BESS and substation areas to support a smooth transition from construction into testing and commissioning.
