Victoria currently has over 28,000 km of Single Wire Earth Return (SWER) and over 60,000 km of 22kV high voltage electricity cables across the state, which are predominantly bare-wire.

The Powelrine Bushfire Safety Program (PBSP) opened a grant program in April 2016 that was designed to look for overhead cable technology solutions that would reduce the impact of bushfires starting from bare-wire conductors by bringing into the network new, safer conductors at a lower overall cost than undergrounding powerlines.

The grants were open for businesses and research institutes to develop an innovative cable technology that will reduce the risk of bushfires from powerlines.
