St Kilda Junction substation - power supply upgrade project

16 October, 2017

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

A number of design options were presented at a community information session earlier in 2017.

Following community feedback, it was clear a bespoke option that provided other benefits to the community was preferred and PTV have appointed an architect to develop three concept designs.

These designs will be shared with the community for feedback in late November 2017 in order to identify and refine a preferred option.

Meanwhile the precise location of the substation within the Junction has been confirmed and we are commencing early works to prepare the site.


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 will require the removal of some trees on site. This has received approval by the City of Port Phillip (CoPP) Tree Removal Assessment Panel and will also involve a tree amenity value payment to CoPP.

Tree removal is expected to occur during the week of Monday 30 October 2017.

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.
