The Osborne plant located near Adelaide is one of Australia’s largest cogeneration facilities. The 180MW project is a 50:50 joint venture between ATCO Power Australia and Origin Energy and entered commercial operation in December 1998. Osborne sells its electrical output under a long term power purchase agreement to Origin. ATCO Power Australia operates the Osborne plant which is fuelled by natural gas from South Australia’s Cooper basin. The plant has been designed to enable operation in both cogeneration and combined cycle modes. Source; www.atco.com.au Copyright 2012 © ATCO Ltd.
