Strategic planning of our power system is crucial to making smart, informed decisions in the long-term interests of Australian energy consumers.
VicGrid and Transgrid are jointly undertaking the regulatory investment test for transmission (RIT-T) for the Victoria to New South Wales interconnector (VNI) upgrade. This is to assess the technical and economic viability of alleviating power transfer capacity limitations between Victoria and New South Wales.
Project assessment conclusions report
On 14 February 2020, the Project assessment conclusions report (PACR) for the Victoria to New South Wales Interconnector (VNI) was released, marking the third and final report in this RIT-T process.
The report confirms the preferred investment option proposed in the VNI RIT-T Project assessment draft report (PADR) published in August 2019.
The preferred option will increase export capability from Victoria to New South Wales by approximately 170 MW during peak demand conditions in New South Wales.
This option yields the highest net market benefits of all options assessed through the RIT-T process primarily through more efficient sharing of generation resources between the states.
Project assessment draft report
On 30 August 2019, the Project assessment draft report (PADR) was released, representing step 2 of the public consultation process for this RIT-T.
The PADR assesses and identifies the draft preferred transmission investment option which delivers the greatest net market benefits. The PADR also provides a summary of submission received on the Project specification consultation report (PSCR).
AEMO and Transgrid called for written submissions from interested parties, including comments on the inputs, analysis and choice of preferred option.
The submissions closed on 11 October 2019. No confidential submissions were received for the PADR.
Non-confidential submissions received for the PADR
Project specification consultation report
On 15 November 2018, the first stage of the Victoria to New South Wales Interconnector Upgrade RIT-T process was completed, and published a Project specification consultation report (PSCR) for consultation.
The PSCR identified the need to alleviate current and projected limitations on power transfer capacity from Victoria to New South Wales, which are resulting in market costs through less efficient sharing of generation resources between states.
Non-confidential submissions received for the PSCR
AEMO and Transgrid called for written submissions from interested parties in relation to the credible network and non-network options presented, and other issues addressed in the report.
One confidential submission was also received.
Stakeholder engagement
We're committed to working with industry, government, investors and consumers to secure and shape Victoria's energy future in the long-term interests of consumers.
We value your feedback and advice on this RIT-T and are committed to ongoing dialogue with our stakeholders.
We will continue to provide updates as we move through this program and welcome your thoughts via our stakeholder engagement activities which will be announced on this page in the coming months.
