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.
The patrols check for vegetation encroachments along transmission line easements, identify potential bushfire risks and assess the condition of TransGrid towers and transmission lines.
2021 patrol period
In 2021 we will be flying across the network between May and July.
The helicopter will fly low near transmission lines at about 50 kilometres per hour and may startle livestock in rural areas so property owners may want to consider securing animals during the patrols.
Thank you for your patience and understanding as we carry out these critical inspections.
