Transmission Line

Planning for the transmission line is underway and at this early stage it is proposed to get the electricity off Robbins Island via the bridge and causeway structure and transmission line to Jim’s Plain. The transmission line will then run from south-east of Jim’s Plain to a substation at Nook near Sheffield. Currently we have selected a preliminary route with the final route subject to consultation and relevant approvals.

Frequently Asked Questions

The line is required to deliver the energy generated at Robbins Island and Jim’s Plain Renewable Energy Parks to the Tasmanian electricity grid.
Connecting into Smithton and Burnie were both investigated; however, Nook, near Sheffield is the best option to enable the safe and efficient transmission of power generated at Robbins Island and Jim’s Plain.
The Second Bass Strait Interconnector (Marinus Link) is crucial to deliver the energy generated from Hydro Tasmania’s Battery of the Nation project to the Australian electricity grid. The Second Bass Strait Interconnector will also enable full development of the Robbins Island Renewable Energy Park. The Second Interconnector is expected to be completed by 2025. The transmission line and associated infrastructure will connect into this.
  • Avoiding areas of high environmental and heritage significance.
  • ƒƒMinimising the impact on private landowners by preferencing Crown land and corporate land wherever possible. ƒƒ
  • Working closely with landowners to identify the best route through their land to limit the impact on current and future business practices and plans.
  • ƒƒMinimising the impact on visual amenity.
This is a key component of our route selection process. We will site the line to have a minimal impact on visual amenity as far as possible. The visual impact can also be minimised by assisting affected parties with screening or alternate route selection. This is also true for potential tourism sites affected by the line of site to towers.
Approximately 400 towers will be constructed along the 170 km transmission route (from Robbins Island to Sheffield) with an average of 400 m spans between the towers.
The towers will be approximately 45-55 m high depending on the terrain.
In areas where the transmission line crosses forestry land, logging will not be able to occur within the 60 m transmission line easement.
UPC has received registrations of interest from local members of the community and businesses interested in becoming involved in the construction and ongoing operation of the renewable energy parks. We are now encouraging people to register their interest to be involved with the transmission line. The wider community will also be crucial in providing accommodation, food and other services to the workforce.
The renewable energy parks will offer significant job opportunities during construction and ongoing operation, this is the same for the transmission line. The renewable energy parks are likely to require up to 400 people during construction and at full development, an operational workforce of up to 50 people. The construction of the transmission line is likely to involve up to 100 people.
Yes, as the easement surrounding the transmission line will be cleared it will act as a firebreak, it will also provide access to neighbouring properties during a fire.
No, transmission lines do not create television interference.
The transmission line will require the following approvals:
  • Development Application (DA) approval will be required from five Councils, including Circular Head, Waratah-Wynyard, Central Coast, Burnie and Kentish. The DAs will need to consider a number of issues including land tenure, environment, heritage and visual impacts.
  • Some locations along the route may require Australian government approvals.
ƒ A rigorous program of studies will be undertaken to ascertain the potential impacts to eagles along the transmission line route. Regulations will be followed as part of the Development Application process and the studies will comply with Tasmanian and Australian government requirements.
Transmission towers are earthed and are protected against lightning strikes.
The company developing, constructing, owning and operating the renewable energy parks, and associated infrastructure, is 25% Australian owned. The remaining 75% is passive ownership held by shareholders from the USA, Europe and the Philippines. The development and construction team is 100% Australian, all based in Tasmania. The team has more than 100 years of combined renewable energy development in Tasmania.
Robbins Island & Jim’s Plain Renewable Energy Park will pay for the transmission line infrastructure required to connect to the network.
We have has evaluated these options and found them to be cost prohibitive, as it makes the renewable energy park projects economically unviable. Initial cost estimates for both transmission options are around $1.5b-$2b. Typically it costs between 5-10 times more for a submarine or underground line than an overhead line. Underground lines have different environmental challenges.
Woolnorth line is a private line and at capacity Smithton Burnie Line is already at capacity
The route options have been developed over 12-15 months of analysis of existing environmental and land tenure information. Initial discussions with directly affected landowners, those with towers and spans on their property, resulted in verbal agreement allowing us to then commence broader consultation with the community. The next stage of selection process is to further refine the route selection with key stakeholders and the broader community.
Feedback from a recent community meeting outlined a number of issues around the proposed route passing through Leven Canyon Regional Reserve. Based on this feedback, we have committed to seeking an alternative to the Leven Canyon route. Further consultation with landowners and wider community will occur as the project progresses.
We encourage you to provide any feedback through our email participate@ghd.com or phone 6432 7999 and Jim’s Plain & Robbins Island Renewable Energy Parks is on Facebook.
