Electric Line Vegetation Clearance

Web Content Tile

Under Section 80 of the Electricity Safety Act 1998, CFA assigns “low” and “high” fire hazard ratings for electric lines to parcels of land in the country area of Victoria.

The classification of low and high risk areas aims to safeguard life and property by preventing overhead electric line-related ignitions. 

Fire Hazard Ratings for Electric lines

CFA maintains a GIS data base that shows the Low Bushfire Rated Areas (LBRA) and the High Bushfire Rated Areas (HBRA) in relation to electric lines. To access this layer simply send us an email, with your name and contact details. Please note that the existing GIS data layer is correct as at May 2014. A review of the data is scheduled to start in 2019.

Where are the rating classifications used?

The ratings are used to identify low and hazardous bushfire risk areas for the Electricity Safety (Electric Line Clearance) Regulations 2015, Electricity Safety (Installations) Regulations 2009 and Electricity Safety (Bushfire Mitigation) Regulations 2013.

How does a rating affect an area?

It can affect the extent of vegetation clearance adjacent to overhead electric lines. Authorities responsible for the overhead electric lines include electricity distribution businesses, municipal councils and private land owners.

It can also affect overhead electric lines on private land. Under the Electricity Safety (Installations) Regulations 2009, a private electric line needing substantial reconstruction must be replaced underground, if sitting in hazardous bushfire risk area categorisation. Private electric lines in low bushfire risk area are exempt from this requirement.

Fire hazard ratings for electric lines contrasts significantly with other risk mapping assessments and has been developed explicitly for its legislative requirements.
