Eraring power station

Since 2018, Downer has been the lead contractor for maintenance services at Origin Energy’s Eraring power station, which is Australia’s largest baseload power station.  Downer’s scope of work includes the provision of maintenance and supplementary services across all units at the station.  The contract has allowed Eraring to move from directly engaging multiple contractors to partnering with Downer who perform the majority of the outsourced work and manage a small number of selected specialist contractors.
