Waddamana to Palmerston Project

Australia’s transition to renewable energy and increasing future energy demands means that Tasmania is diversifying the way electricity is generated. To connect new energy generation projects, TasNetworks needs to strengthen and expand the existing transmission network across Tasmania to increase capacity and energy security.

The Waddamana to Palmerston transmission lines have been identified as an “actionable project” in the Integrated System Plan (ISP), prepared and published by AEMO. The ISP provides an integrated roadmap for the efficient development of the National Electricity Market (NEM) over the next 20 years and beyond.

There is enormous potential for future renewable energy developments in the Central Highlands.

The Waddamana to Palmerston transmission lines are critical for energy security in Tasmania as they provide the only transmission link between the north and south of the State.

TasNetworks is currently looking at ways to make best use of the transmission network already established between Waddamana and Palmerston substations and is exploring options to expand the network to increase both capacity and energy security.


We are prioritising engagement with stakeholders and the community at this early phase in the project to gain insights about the local area, local values, and local needs. This valuable feedback will help inform decision making.

  • - Overview -

    Australia’s transition to renewable energy and increasing future energy demands means that Tasmania is diversifying the way electricity is generated. To connect new energy generation projects, TasNetworks needs to strengthen and expand the existing transmission network across Tasmania to increase capacity and energy security.

    The Waddamana to Palmerston (WA-PM) transmission lines are critical for energy security in Tasmania as they provide the only transmission link between the north and south of the State. As such, TasNetworks is currently looking at ways to make best use of this transmission network to expand the network to increase both capacity and energy security.

    At TasNetworks our engagement approach recognises that major ‘generational’ initiatives such as WA-PM affect the whole community. Consequently, we are seeking out and hearing from the broadest cross-section of the community by making it as easy as possible to find information and provide feedback in relation to the Waddamana to Palmerston project. 

    It is important for us to listen to all community perspectives, and it is critical to our understanding the social impact of the project. Our approach is focused on ensuring that all perspectives are understood and responded to.
