Preferred bidder announced

A preferred bidder has been selected and is in exclusive negotiations.

Recently closed

Projects that have progressed to contractual close remain on ANZIP for 12 months.

ANZIP is focused only on major infrastructure activity, above the following thresholds:


Construction projects: > AUD$300m

Investable greenfield & brownfield: > AUD$100m

HumeLink involves the development  of new high-voltage transmission capacity within NSW to accommodate Snowy 2.0. This project would feature new transmission developments that can reinforce the network to increase transfer capacity between the Snowy Mountains, southern New South Wales, and the major load centres of Greater Sydney.

The project would includes:

  • a 500 kV single circuit between Wagga and Bannaby and a 500/330 kV transformer at Wagga
  • a new substation in Snowy with 500/330 kV transformers
  • a 500 kV line between Snowy 2.0 and Bannaby
  • a 500 kV line between Snowy 2.0 and Wagga
  • two 500 kV circuits between Darlington Point and Wagga
  • a power flow controller on the Bannaby-Sydney West 330 kV line, and
  • a 500 kV transformer at Bannaby.


In December 2018, the Energy Security Board's Integrated System Plan - Action Plan stated that AEMO is working with Snowy Hydro and TransGrid to refine and extend ISP modelling to better understand the costs, benefits and factors that affect the timing of these projects.

TransGrid has commenced the Regulatory Investment Test for reinforcement of the NSW Southern Shared Network to increase transmission between demand centres. TransGrid released a Project Specification Consultation Report in June 2019, which includes consideration of the transmission upgrades under HumeLink.

In July 2019, AEMO released an Insights paper in support of the 2018 ISP that flagged the need to accelerate development of HumeLink to prepare for Snowy 2.0.
