Australian Steel Solution for the Northern Transmission Project (NTx)

Summary and scope

Project: Australian Steel Supply for the Northern Transmission Project (NTx) - Registration of Interest Project owner: ELECTRANET PTY LIMITED Location: SA Australia Work package status: Open Scope: Full Scope Work package description: Suppliers are requested to refer to the attached documents for full details. Project overview: The Northern Transmission Project (NTx) is a major infrastructure initiative supporting South Australia's transition to a clean, reliable and economically sustainable energy system. The project will expand transmission capacity to unlock renewable energy resources north of Adelaide, meet growing electricity demand in the Adelaide load centre, enable connection of new large industrial users, and reduce network congestion from the Mid North region. The project comprises two new high-capacity transmission line sections: a southern section connecting Bundey to a new substation north of Adelaide, and a northern section connecting Bundey to Whyalla via Yunta, together strengthening the state's electricity network and supporting future growth.ElectraNet is the owner and operator of South Australia's high-voltage electricity transmission network, delivering power from large-scale generators to distribution networks and major industrial customers. We play a key role in the state's transition to a clean energy future, designing, operating and managing critical infrastructure to provide communities and industry with affordable, reliable and sustainable energy.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; andAlleviates 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: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; andNorthern 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:This Registration of Interest - this will inform shortlisting for Stage 2: EOI.Expression of Interest (EOI) -issued to shortlisted respondents for detailed technical and commercial (pricing) information; andFuture 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.For further details please visit: https://ntxproject.com.au/
