Clearance zone

Stay safe by respecting clearance zones

Landowner’s activities are limited for safety purposes within clearance zones. These zones are applied to electrical infrastructure in the absence of a registered easement.

The guidelines by which activities are limited are in line with easements.

Assessment of clearance zones is critical

The distance of a clearance zone is defined by the Australian Standard for overhead line design (AS/NZS 7000:2010).

Western Power does not support any development within the clearance zone of an overhead powerline unless the area has been properly assessed and approved in accordance with relevant standards and procedures.

Western Power or a suitably qualified and competent professional can assist you to calculate the clearance zone on request. We complete the engineering assessment, which includes a survey component. You can arrange for the survey through a licensed surveyor.

Be aware that upon a study being conducted to determine the clearance zone, a building cannot be safely built unless it also complies with danger zone requirements prescribed in section 3.64 of the Occupational Safety and Health Regulations 1996.
