This major upgrade to the transmission network will boost interstate power flows and help deliver safe, reliable, lowest cost electricity to customers.
VNI Upgrade fact sheet.
An electricity interconnector is a connection that allows power to flow in both directions between regions in the National Electricity Market, providing access to a larger number of electricity generators.
Upgrading the Victoria – New South Wales Interconnector (VNI) will allow cheaper generation to be transferred between the two states. This will help lower the cost of wholesale electricity across the National Electricity Market and put downward pressure on customer bills.

The project has been identified as a priority by both the Australian Energy Market Operator in the
2020 Integrated System Plan and by the State Government in the
NSW Transmission Infrastructure Strategy.
TransGrid plans to install ‘smart wires’ power flow controller technology within Yass substation in NSW and our new
Stockdill substation in the ACT.
‘Smart wires’ technology enables the real-time control of electricity flows along power lines. The system detects areas of congestion in the network and automatically redirects flows to less congested lines. It will help unlock spare transmission capacity, allowing more energy to be transferred between Victoria and NSW.
AEMO will undertake complementary upgrades to the transmission network in Victoria.
TransGrid and AEMO received nine public submissions on the PSCR and six on the PADR. Submissions received (and approved for publication by proponents) can be viewed on the
TransGrid has submitted a Contingent Project Application to the Australian Energy Regulator seeking approval to vary TransGrid’s current 2018-23 Revenue Determination by an amount that reflects the prudent and efficient costs of the NSW component of the project.
