Transmission – Easement Use

AusNet Service manages the entire Victorian electricity transmission network, which includes power station switchyards, transmission towers and powerlines, and terminal stations.

Across our network, 12,800 transmission towers run in corridors across more than 17,500 hectares of land. We refer to these corridors of land as ‘transmission line easements’ or ‘easements’ for short.

In general, we don’t own this land, so instead we compensate landowners for the rights to access our transmission network, and we restrict planting and building on easements.


Average specifications

Please refer to the image below for an overview of our transmission towers, including the average height and width for each.

Transmission line easement use

Please note our easement widths allow for movement of electricity transmission conductors, which can be affected by factors such as wind, temperature and electrical load.

For specific details relating to transmission towers and powerlines on your property, check your Certificate of Title as easement measurements can vary.

Additional information can also be found in our Guide to Living with Transmission Line Easements.

 

Planting on easements

To help us maintain clearance zones around an easement, please ensure that any planting on your property complies with the following requirements:

  • vegetation must not grow to more than 3 metres
  • vegetation should be scattered or clumped so that it covers no more than 10 percent of the easement area.

 
Clearance zones are established by Energy Safe Victoria and are outlined in the Code of Practice for Electric Line Clearance (Vegetation).

By complying with the above requirements, you will also help to reduce the need for us to access your land to remove inappropriate vegetation.


Building on easements

If you wish to build on or around an easement, please note that AusNet Services and Energy Safe Victoria have strict requirements, which are outlined below.

Permitted structures

Landscaping and paving – provided there’s sufficient clearance from conductors and towers, if you’re planning to alter the natural surface level.

Fences (subject to approval) – provided they are no more than 3 metres in height, and suitably earthed and sectionalised (if they are metal or contain metallic materials).

Sewerage, drainage or water pipes – provided they are constructed of earthenware or plastic materials.

Tennis courts (on 330 or 500 kV easements) – subject to certain specific requirements.

Tennis courts (on 220 kV easements) – provided that metal net posts are used and the minimum distance from the surrounding fence to the nearest tower steelwork is 20 metres; an elevated umpire’s chair is also permitted, provided it’s of all metal construction and has a metal screen above the seating position.

Lighting poles – provided there’s sufficient clearance form conductors and towers; the power supply must be underground and you must be able to lower the poles the ground for maintenance.

Playground equipment – provided it’s no more than 1 metre in height.

Water storage dams – provided there’s sufficient clearance from conductors and towers, and the effect on the water table has been considered.


Prohibited structures

  • Houses and other buildings – including eaves, awnings, canopies, shelters or similar*.
  • Scaffolding – of any description.
  • Swimming pools – both above- and below-ground, including any filtration equipment.


* For 220 kV easements only
– domestic garages, carports and garden sheds may be permitted a limited distance onto the easement, but only if: there’s sufficient clearance from towers; the structure is no more than 3 metres in height; construction is largely of non-flammable materials; and the structure isn’t attached to a dwelling.

 

Working on easements

For public safety reasons – and to ensure a reliable electricity supply – we limit the types of activities you can undertake on your transmission line easement.
 

Permitted work

Farming – agricultural and grazing.

Operating market gardens, orchards and horticultural nurseries – excluding buildings.

Parking of sedan and utility vehicles – barriers of an approved design may be required to protect towers from damage by vehicles.

Operating car, boat and trailer sale yards – for 220 kV easements only.

Operating ground level sports facilities – such as football or cricket ovals, golf courses, basketball or netball courts (subject to special requirements for the design of fences, goals and lighting).


Prohibited work

Storing materials – including waste bins and stock-piled excavation materials.

Storing or handling flammable liquid or gas from bulk vehicles (on 500 kV easements only) – not permitted within 60 metres of the centre line of the transmission line,

Using vehicles and equipment exceeding 3 metres in height– a higher operating limit is subject to sufficient clearance from conductors.

Parking of large trucks and caravans – including for loading, unloading or adjusting loads.

Operating spray irrigators – of the large water gun type.

Detonating explosives – please contact us before storing or detonating explosives in the vicinity of your easement.
