The Relationship 

Enerven commenced its maintenance service provision relationship with ElectraNet in 1998, whilst still operating as part of ETSA Utilities under the Construction and Maintenance Services group.

Our commitment 

Enerven have always been there for ElectraNet - from Mt Gambier to Port Lincoln to Pimba and everywhere in between, rain, hail or shine, day or night, when ElectraNet need us, we are there.

Our greatest example of this has to be the state-wide blackout South Australia experienced in 2016. The blackout was caused by severe and wide-spread weather conditions, which the Bureau of Meteorology described as being the worst in 50 years. Over 100 employees were coordinated and deployed to provide an emergency response unit to repair 22 fallen structures, which occurred on three critical transmission feeders during the storm.

Our employees worked around the clock in extreme conditions to ensure power was restored to the State safely. Temporary and replacement transmission towers were brought into South Australia from interstate to eventually replace the 22 towers severely damaged by strong winds, and on average power was restored to customers within 16 hours.

We support our client’s goals and vision to be a leader in Transmission Network Service Provision and we do this by providing industry best practice Asset Management Services.
