High Quality Content by WIKIPEDIA articles! Yallourn Power Station was a complex of six brown coal fuelled power stations built progressively from the 1920s to the 1960s. Located in Victoria`s Latrobe Valley, the complex was situated beside the Latrobe River, with the company town of Yallourn located to the south west. Today only the 1,450 MW Yallourn W plant remains, the third largest power station in Victoria which supplies 22% of state`s electricity and 8% of National Electricity Market needs. The adjacent open Yallourn brown coal mine is the largest open cut coalmine in Australia, with reserves to meet the projected needs of the power station to 2032.
