In the first stages of planning a new development, an action that is considered reasonable for Local Government Authorities to take to assist with land use planning and future development decisions, is to check whether any electrical infrastructure is located within the proposed works corridor.

The structure plan, future subdivision and development processes must protect the transmission line corridor and associated assets from encroachment, reduce public safety risks and ensure there is no obstruction to routine and emergency land access to the network.

We’ve developed a clearance assessment mapping tool which provides you with a clear visual display showing all overhead lines to assist you with your planning. If there are transmission assets in the way, you may need to take further action to ensure safety is maintained.

How to use the tool

Enter the address of the proposed development in the search box to find out if any overhead infrastructure is within your proposed development area. Blue lines on the map indicate the clearance zone of overhead powerlines. Wider clearances indicate higher voltage wires.

It's important to note - if there are transmission assets within the area, further investigation needs to be carried out.

A submission to Before you Dig –  will provide you with descriptions of underground hazards, like electrical cables, and is an essential planning activity in addition to checking our clearance map.

Launch the tool

We offer a number of options and services for proposed works that may be impacted by transmission (66,000 volts - 330,000 volts) and communication assets. These include:

  • relocation of transmission assets
  • relocation of communication assets
  • clearance assessments
  • earth potential rise / low frequency induction studies
  • provision of technical data
  • civil / structural assessments
  • de-energising the transmission line (requires at least 40 business days’ notice).

If there are Distribution assets within the works area

Our Products and Services pages let you select the correct application to move or remove assets or to present a proposed requirement for design of a new installation. This is the correct path to use if attempting to give qualified costs for electrical works for a proposed development.

Proposed road closures or property boundary changes

Road closures and property boundary changes may not physically change the land our assets sit on, however there are circumstances where we may still need you to move or remove our equipment given the new boundary arrangement.

If the new property boundary changes the relationship of distribution equipment to that boundary, i.e. poles, cables, or ground mounted equipment formerly in the road reserve or running in proximity to the old boundary are now well within the property, an application will need to be made to move or remove equipment. This application will determine if an easement is required or if physical work is necessary.

Even if our assets are present but not affected by a boundary change, continued access for maintenance and emergency response must be provided. If this is not via the original road path, changed access conditions should be communicated via our Land Entry Preferences form.
