Cost Model of the Leigh Creek Coalfield

The Leigh Creek Coalfield is owned and operated by the Electricity Trust of South Australia to supply fuel to the Northern Power Station. To supply electricity at lowest cost, a costing and decision process that establishes the role of the Leigh Creek Coalfield in the overall system planning and operation is required. The costing is integrated in that it is based not just on a particular mine plan but on the wider need to supply a particular electrical demand. The detail costing has evolved over time from manual to main-frame computer to microcomputer techniques. Now there is a choice between fast consistent costs and a slower but more detailed and flexible costing.
