The Northern Transmission Project (NTx) is a critical component of South Australia's broader strategy to transition toward a clean, reliable and economically sustainable energy system. The Project aims to further unlock South Australia's renewable energy potential and strengthens it economic resilience.

Augmenting this part of South Australia's transmission network:

• Supports growing demand in Adelaide to be supplied by expected increase in renewable generation north of Adelaide.

• Provides additional network capacity to supply new large industrial loads, recognising the high level of interest from those loads to connecting to our network; and

• Alleviates congestion on renewables from the Mid North region to the rest of the National Electricity Market.

The NTx Project is divided into two distinct sections:

1. Southern section - To provide a new high-capacity transmission path, approximately 130km of 330kV transmission line (initially energised at 275kV), enabling energy demand growth for the Adelaide load centre. This section will connect Bundey with a new substation North of Adelaide; and
2. Northern section - To provide a new high-capacity transmission path, approximately 450km of 330kV transmission line (initially energised at 275kV), enabling connection of large industrial loads in the Upper Spencer Gulf region. This section will connect Bundey with Whyalla, via Yunta.

These sections serve complementary purposes in addressing South Australia's electricity network needs. ElectraNet is working with communities to determine possible routes for the transmission lines.

ElectraNet is undertaking this Registration of Interest (ROI) to understand the capability, capacity, and readiness of the Australian market to supply Australian manufactured and fabricated tower steel for the NTx Project. The ROI aims to identify potential suppliers and consortiums, assess domestic capability across steelmaking, fabrication, galvanising, and logistics, and gauge industry interest in participating in later procurement stages. Information gathered through this process will help ElectraNet determine the extent to which Australian industry can meet the project's technical, schedule, and cost requirements and will inform subsequent procurement activities.

A three-stage approach will be followed:

1. This Registration of Interest - this will inform shortlisting for Stage 2: EOI.
2. Expression of Interest (EOI) -issued to shortlisted respondents for detailed technical and commercial (pricing) information; and
3. Future Tender (during the early contractor involvement (ECI) phase of the Project).

ElectraNet invites responses from parties capable of providing a full end-to-end Australian steel supply solution, including steelmaking, fabrication, galvanising, and logistics. Consortium-based approaches are welcomed, particularly where they combine complementary capabilities to form an integrated domestic supply chain for the NTx Project.
