AusNet Services currently operates 6,500kms of transmission lines across Victoria.
Critical upgrade of the state's transmission network
Our energy network was originally built to carry energy generated from brown coal in the Latrobe Valley to the rest of the state. As we move from coal-generated electricity to sustainable green power, this critical upgrade of the transmission network will help to keep the lights on and power prices down.
Playing a key role in energy supply availability
A new transmission line is required to deliver renewable energy from wind and solar farms in western Victoria, a key renewable energy zone, to homes across Victoria and into the National Electricity Market. This project is needed to urgently reduce congestion on the existing transmission network and to help unlock significant amounts of clean electricity for Victorians.
The project will involved major economic investment in western Victoria. Many local goods, services and contractors are expected to be used throughout construction.
The Western Victoria Transmission Network Project is still in Stage 1 of the planning, design and approvals. The proposed project requires Victorian and Commonwealth Government approval as well as extensive community consultation through the Environment Effects Statement process before construction may commence.
Electricity travels via two types of power lines – transmission lines and distribution lines.
Transmission power lines transport electricity at extra high voltages from generators such as a coal-fired power stations, wind or solar farms, to terminal stations. They generally range in voltage from 132kV up to 500kV. The voltage of electricity from the transmission network is stepped down at the terminal stations and substations to a lower voltage before it is transferred to the distribution network.
Distribution power lines transport the electricity from the substations and carry electricity through many of our residential streets to homes and businesses. They range in voltage from 240V up to 66,000V (66kV).
The transmission network and distribution networks are different types of infrastructure and require a different management approach. Each network has specific management plans that set out processes and procedures for fire prevention and vegetation management.
In compliance with ESV regulations, AusNet Services has prepared Vegetation Management Plans and Bushfire Mitigation Plans for both the transmission and distribution networks that are audited annually by ESV. The plans are available here.
The transmission towers in the 220kV section of the WVTNP from Bulgana to north of Ballarat will range in height from 40 to 60m.
The transmission towers in the 500kV section of the WVTNP from north of Ballarat to Sydenham will range in height from 60m to 80m.
The transmission towers will be generally within 450 to 550m apart.
The 500kV double circuit transmission line will be designed with a minimum ground clearance for the transmission line of 15m above the ground.
The 220kV double circuit transmission line will be designed with a minimum ground clearance for the transmission line of 9.2m above the ground.
More information about height clearances, no go zones, and vehicle and equipment height clearances is available in the Landholder Guide: Land access, easements and compensation.
The proposed terminal station will be located to the north of Ballarat with the final location dependent on the route determined for the project.
An indicative area for the terminal station to the north of Ballarat has been identified on the proposed route. The area shown is representative of the area of land required, however there may be changes depending on the layout and orientation of the final terminal station design which requires it to be in a different position on the property. The land size of the terminal station will be approximately 400 x 600m.
The size of the proposed terminal station is estimated to be 100m x 500m and approximately 50,000m2. This is equivalent to approximately 12.35 acres.
As a comparison to the Melbourne Cricket Grounds (MCG), the proposed terminal station measures slightly smaller than the MCG and its grandstands (59,800m2).
