HumeLink West

HumeLink West

HumeLink West is one of two sections that make up the 385 kilometre HumeLink project. HumeLink West is a transmission route that runs from to Wodalga, where it connects with HumeLink East and to the proposed Maragle substation. 

The $1.5 billion HumeLink West major contract includes: 

  • 148 kilometre of transmission line from Wagga Wagga to Wodalga, and to the proposed Maragle substation to Wodalga
  • the construction of two new 500/330 kV substations at Gregadoo (Gugaa substation) and Maragle, and 
  • the upgrade of the existing 330kV Wagga Wagga substation. 

Both major contracts (HumeLink East and HumeLink West) comprise two stages: 

  • Stage One - pre-construction activities - including early works, detailed design, investigations, procurement including long lead equipment procurement such as locking procurement of steel towers, and project mobilisation. 
  • Stage Two - main works construction - including construction of transmission lines and upgrading substations. 

During Stage One, Transgrid is undertaking its own procurement of key long lead items including reactors, transformers and conductors. 

Construction of HumeLink East and West will occurr concurrently.
