, the station was commissioned in 1999 with a single 300 megawatts steam turbine. Power generated by the station supplies the south-west of Australia through the South West Interconnected System (SWIS) operated by Western Power. In the financial year of 2008/2009, the station consumed approximately of coal. Carbon Monitoring for Action estimates that, in 2009, Collie Power Station emitted of to generate of electricity. In household consumer terms, this equates to of emitted for each one kilowatt-hour (kWh), or , of electricity produced and fed into the electricity grid. That is, Collie Power Station emits slightly less per kilowatt-hour of electricity produced than nearby closing Muja Power Station () but more than also nearby
