Aerial Patrols

Inspecting our transmission network

Every year, specialist helicopter patrols check more than 13,000 kilometres of transmission lines and infrastructure across our state-wide network. 

These annual inspections are an important part of our comprehensive maintenance program, and ensure the transmission network is safe for our staff and the community. 

2020 patrol period

Over the coming weeks, helicopter patrols will inspect the electricity network to check for vegetation encroachments along transmission line easements,  identify potential bushfire risks and assess the condition of TransGrid towers and powerlines.

Weather permitting, we will inspect high voltage transmission lines across the following areas.
