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, VIC.
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 started working with local communities to discuss preliminary works, including environmental surveys and route identification. 

    Feedback from communities will be used to help plan the route, minimise project impacts and maximise benefits for the region.

    To best meet the needs of our communities we use a variety of communication channels which include face-to-face community information sessions, one-to-one meetings and community displays. 

    We will conduct a series of community drop-in and information sessions in project areas across the life of the project. 

    The drop-in sessions will provide information about the scale of the project and give residents and local businesses the opportunity to comment on the proposed route alignment.  

    Upcoming community information session details:

    The health and safety of regional communities, our staff, and contractors remains our priority. COVID-19 safety plans adhering to government regulations, health and hygiene guidelines, physical distancing rules and NSW Government practices for public gatherings will be in place at each location.

  • 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. 
    TransGrid will lodge a Contingent Project Application (CPA) later this year. See our latest media release.
