Western Victoria Transmission Network Project

Overview: AusNet Services is planning a 190 km overhead high voltage transmission line in western Victoria. Moorabool Shire is earmarked for 60 km of the 500kV lines from the eastern boundary to the west. Council is active in the planning process for the project, advocating for good community outcomes. This includes investigating options for the lines to be put underground, the Green and Unseen campaign, consistent correspondence with decision-makers and hosting education sessions with technical experts to help empower our community.

Project background

What is the project? 

AusNet Services has been awarded the contract to design and construct 190 km of new overhead high voltage transmission lines from Sydenham to Bulgana, a new terminal station to the north of Ballarat and several electricity infrastructure upgrades across western Victoria. Whilst the final alignment of the transmission line has not yet been determined, AusNet Services has reduced the area of interest to a preferred corridor and is currently undertaking investigations to determine the final route. 

Moorabool Shire is proposed to have almost 60 km of the 500 kV transmission lines from the far west border through to the east and may also house the new terminal station. 

Project approvals 

AusNet Services is preparing an Environment Effects Statement (EES) for the Western Victoria Transmission Network Project, as mandated by the Minister for Planning in August 2020.

The Minister for Planning issued the final scoping requirements in December 2020 which broadly outline the issues that AusNet Services must address in the EES.

Read the Environment Effects Statement Scoping FAQs.(DOCX, 2MB)

Once completed, an inquiry will consider the EES and submissions, conduct a public hearing and report in writing to the Minister, who will then make his assessment and provide it to decision-makers for consideration.  

The project is also classified as a ‘controlled action’ under the federal Environment Protection and Biodiversity Conservation Act 1999 and assessments will be managed by the State Government under this Bilateral Agreement.

Council involvement

What is Council doing? 

We are addressing community concerns and supporting residents by urging decision-makers to put the lines underground and providing transparent information to the public.  

Underground versus Overhead comparison 

In an independent report(PDF, 4MB) commissioned by Council, experts confirm that utilising HVDC underground cables for the WVTNP is a viable, low-impact alternative to the AC overhead transmission lines currently being planned.

Importantly, it also found that the underground option is significantly less than the 10 times greater as referenced by the AEMO Western Victoria Renewable Integration Project Assessment Draft Report (PADR).

Key findings:

  • HVDC underground cables are a technically feasible alternative that is likely to be more reliable and efficient for the movement of renewable energy to major centres whilst presenting significantly reduced impact to social and environmental factors.
  • HVDC underground option will not be impacted by bush fires. Power does not need to be switched off during bush fires to aid firefighting, and the power transmission is highly unlikely to be disrupted due to smoke causing flashovers and potentially tripping breakers.
  • HVDC underground cables provide the lowest impact solution with:

  • Little to no risk of underground cables causing fire or being affected by severe weather events.
  • Little to no impact to access e.g. for emergency services and aviation operations.
  • Minimal impact to private land or current land use once construction is completed as the easement could be designed to fit within existing road reserves.
  • Significantly reduced impact to flora and fauna due to the possible location of the cable along roadways.
  • No visual impact concerning the transmission line as the cables are buried underground.
  • Equivalent or reduced visual and land-use impact from the converter station as it would be expected to occupy a relatively similar area as a typical AC terminal station with much of the equipment being housed indoors.
  • No audible noise along the transmission line.
  • Little to no electromagnetic field impacts.

Underground can be done  

In order to explore the viability of alternative solutions, we commissioned an independent report(PDF, 5MB)  that compares 500 kV Overhead Lines with 500 kV Underground Cables. It confirmed that the undergrounding of powerlines is a viable option. 

Key findings:  

  • To install a portion of the route underground is a technically feasible option
  • Undergrounding significantly reduces the magnetic field level when standing 15m away, compared to overhead lines
  • Underground lines are not susceptible to weather conditions and experience a third of the forced outages
  • The easement requirement for underground is two-thirds of that of above ground 
  • There are less vegetation management requirements for underground lines
  • Overhead lines emit audible noise whereas underground lines do not

Local economic impact assessment

Council commissioned an independent local economic impact assessment(PDF, 55MB)  to examine the economic advantages and disadvantages that had not been previously considered as part of the project’s Regulatory Investment Test for Transmission (RIT-T) process.

Key findings:

  • The RIT-T does not appear to consider costs or benefits outside the electricity market.
  • The RIT-T process selects a preferred option on the basis of net direct electricity market benefit and does not take into account any local, indirect or non-market impacts (positive or negative).
  • The capital costs considered include construction, operation, maintenance, regulatory costs, and easements. It is apparent that no other costs are considered such as non-market economic, social, and environmental impacts.
  • The benefits assessed include price benefits to electricity consumers and the profitability of energy production and subsequent flow to business.
  • It is apparent that no other benefits are considered, including non-market economic impacts.

Green and Unseen campaign 

Council has launched a campaign called Green and Unseen which urges AusNet Services to put the transmission lines underground.  
We are proud to produce renewable energy through our wind farms, but putting the powerlines overhead is not green and is actually dangerous to Moorabool residents – hence our Green and Unseen campaign.


Empowering the community 

Moorabool Shire Council recently hosted another online community session in relation to the Western Victoria Transmission Network Project (WVTNP). It was the latest in our successful community series established in 2020, inviting technical experts to share their knowledge with the public on various topics to shed light on the complexities of the project. The session focused on how to prepare a strong submission to the WVTNP’s Environment Effects Statement (EES) when it is exhibited for public comment later this year, and how the process itself will work.
