Supporting growth in renewable energy

TransGrid is partnering with ElectraNet to deliver a 900 kilometre energy interconnector between the power grids of South Australia and New South Wales, with an added connection to Victoria. This will enable the sharing of energy between NSW and SA, lower wholesale energy costs and support growth in renewable energy generation.

What is EnergyConnect?

EnergyConnect involves the construction of a new transmission line connecting New South Wales, South Australia and Victoria. The proposed interconnector would be around 900km long and run between Wagga Wagga in NSW and Robertstown in SA, with a connection to Red Cliffs, in VIC.

Where required, supporting infrastructure along the proposed route will also be upgraded or established. This includes substations, access tracks and roads, and laydown / staging areas.

EnergyConnect is a key element of the Australian Energy Market Operator’s Integrated System Plan, and the NSW Government has declared it Critical State Significant Infrastructure.

Why is the project needed? 

The Australian energy landscape is transforming with an increased focus on low-emission renewable energy sources. At the same time, consumers are demanding lower power bills and without reducing energy security and reliability. To connect Australian communities and businesses to these lower-cost new energy sources, the national electricity grid needs to evolve.

What are the project benefits?

If approved, EnergyConnect would deliver a range of benefits for customers in New South Wales, South Australia and Victoria including:
  • increased regional economic activity
  • increased renewable energy generation
  • increased job opportunities
  • lower power prices for consumers
  • a more secure energy supply. 
  • Community engagement

    EnergyConnect has been actively working with communities to obtain local knowledge and feedback on an initial area of interest for the proposed transmission line.

    Project representatives have: 

    • met with landholders to discuss the project and understand opportunities and constraints relevant to their properties
    • held a series of community drop-in information sessions to obtain valuable local knowledge and answer questions about the project
    • engaged council representatives and State government MPs to provide project details including regional benefits and anticipated timeframes.
    The next round of community information sessions will be held in:
    • Booroorban: 18 September, 10am–1pm, Booroorban Hall, Wargam Rd. 
    • Uranquinty: 19 September, 9am–12pm, outside the Quinty Bakehouse, Morgan St. 
    • The Rock: 20 September, 10am–1pm, The Rock Hall & Museum, Urana Street. 

    The project has also been using an online tool to help capture community feedback. The interactive map shows the initial area of interest for the proposed transmission line and allows landholders and community members to provide local knowledge and feedback on specific locations. 

    EnergyConnect has received valuable local knowledge as a result of the commitment from the community. TransGrid would like to thank everyone who has provided feedback, talked with the project team or taken the time to attend one of the community information sessions. 

    The project team is still keen to hear from local communities, residents and interest groups. To provide feedback visit the interactive map, phone 1800 49 06 66 or email  

  • Project funding approval
    To be given final investment approval, EnergyConnect must be shown to provide benefits to consumers. Consumer benefits are assessed using a three-part market benefits test (Regulatory Investment Test – Transmission or RIT-T) administered by the Australian Energy Regulator (AER).  
    The RIT-T process assesses all network and non-network solution options from a technical and economic perspective by:
    • informing stakeholders of investment need and proposed options to address it
    • testing the market for alternative and more efficient solutions
    • explaining to stakeholders the basis on which the preferred option has been selected.
  • RIT-T process

    In January 2020, the Australian Energy Regulator (AER) approved the Regulatory Investment Test for Transmission, known as a RIT-T for the Project. This test is a rigorous cost benefit analysis overseen by the AER. 

    “With ElectraNet, TransGrid is committed to delivering the project at the lowest possible cost with the greatest benefit to energy consumers,” said CEO Paul Italiano. 

    The AER has commenced public consultation on contingent project applications received from ElectraNet and TransGrid for Project EnergyConnect. Submissions are invited on the contingent project applications for Project EnergyConnect by 30 October 2020.

    Visit the AER website for further details on submissions.
