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. 

2021 patrol period

Helicopter patrols periodically 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. 

Aerial patrol dates and locations for 2021 will be published here when available.
