St Kilda Junction substation - power supply upgrade project

Melbourne has the world's largest tram network, with around 600,000 trips each weekday. That will increase to over one million trips a day by 2031. To meet this demand, the Victorian Government is revitalising the network by investing in new trams and infrastructure.

Melbourne's trams are powered by an extensive power network that needs to be regularly maintained and upgraded. Substations are a key requirement to keep Melbourne's trams running into the future.

New St Kilda Junction substation

Public Transport Victoria (PTV), in partnership with Yarra Trams, is constructing a new tram power substation at St Kilda Road, St Kilda Junction.

This work is part of the Victorian Government's investment in new trams and modern infrastructure across Melbourne to boost capacity for the future demand of our tram network.

Substations are common across the network and this one has been strategically placed to provide power to nearby Routes 3/3a, 5, 16, 64 and 67.

Substation design

Public Transport Victoria (PTV) and Yarra Trams engage with local communities whenever a new substation is built.

As part of this project a community session was held in May 2017.

Since this time, and following engagement with the Junction Area Action Group, local firm Jackson Architecture has been briefed on the feedback and appointed to independently design an architectural treatment for the substation.

Three concept designs are now ready to be shared based on the input of JAAG and the City of Port Phillip.

PTV and Yarra Trams would like to invite the local community to attend an information session to find out more about the concepts and share your thoughts.

  • St Kilda Library Community Room - St Kilda
  • 150 Carlisle St, St Kilda
  • Wednesday 22 November 2017
  • Time: 6pm - 8pm
  • Nearest Tram Stop: Stop 36 Tram Routes 3, 3a & 16

Members of the project team will be available to answer any project related questions you may have. You can attend at any time during the session.


Early works will commence in late October 2017, with the erection of temporary site fencing and delivery of a work site office. Earthworks will begin in November 2017, including the preparation of foundations and construction of conduits.

Work will mainly be carried out weekly from Monday to Friday, 7am - 5pm. We expect to complete the works in seven months; however, the level of on-site work will vary during this time with some periods of low activity.

We will provide advance notice of construction activities likely to cause disruption.

What is planned?

The scope of works include:

  • pouring of concrete base
  • construction of new cable pits
  • installation of prefabricated substation (early-2018)
  • internal fit out and power connection
  • testing and commissioning
  • architectural treatment, landscaping and site clean-up.

Vegetation removal

The construction and permanent access to the substation has required the removal of some trees on site. This received approval by the City of Port Phillip (CoPP) Tree Removal Assessment Panel and has also involved a tree amenity value payment to CoPP.

Traffic and pedestrians

Construction vehicles will be moving through the area. At times temporary road lane and footpath closures may be required. Traffic controllers will be present to help minimise disruption to motorists and pedestrians. Please heed warning signs and follow the direction of traffic controllers.

Minimising the impact on the local community

During this time, businesses and residents can expect to hear low level construction-related noise from within the St Kilda Junction median strip. Our workers will be mindful of keeping noise to a minimum and respecting the needs of the local community. 

Keeping the local community informed

PTV and Yarra Trams are committed to keeping the local community informed of construction activity. We thank you for your patience and understanding during this important upgrade work.
