Wilpinjong CHPP Expansion

Back to case studies

Expansion of both the coal handling and processing capacity was required for Peabody’s existing Wilpinjong CHPP mine, located near Mudgee, NSW.

The Wilpinjong expansion project featured a collaborative project delivery approach between Peabody and Ausenco offices located in Australia, the United States and China. Utilising a not-to-exceed reimbursable contract model, Chinese delivered fabrication, US based drafting and a local project management and engineering team proved to maximise value for the Project Owner.

The project scope of work included the expansion of the existing 66kV substation and high voltage reticulation to the CHPP expansion. A secondary ROM system featuring a 400 tonne ROM bin, feeder breaker, scalping screen, secondary and tertiary stacker deliver raw coal to a stockpile dedicated to the CPP, while the existing sizing system is free to dedicate to direct shipped coal.

The addition of a fine dense medium circuit has increased the plant capacity from 800t/h to 1,200t/h, and the addition of a 100,000 tonne washed coal stockpile improves storage and flexibility for product shipments.

  • Project was delivered safely with over 250,000 man hours LTI free
  • Project handover occurred on time and was delivered under budget.
