Our tree trimming guidelines, standards and plans determine how we manage vegetation across our network. The clearances required between powerlines and poles and tree branches are governed by Ausgrid’s network standard (NS179), the Industry Safety Steering Committee Guide for Management of Vegetation near Electricity Assets (ISSC3) and the Australian Standard Pruning of Amenity Trees (AS4373). Ausgrid also works to specialised training and safety plans that protect our maintenance crews and the health of vegetation that surrounds our electricity network.

Our Tree Safety Management Plan describes our approach to vegetation management in more detail.
