Diamantina Power Station is a modern high-efficiency power station serving the power needs of the Mount Isa region in Queensland. Its power generation facilities provide the region with reliable, on-demand natural gas-fired electricity.

It comprises 242 megawatt power generation from combined cycle gas turbines, plus 60 megawatt back-up from the adjacent Leichhardt Power Station open cycle facility.

Diamantina Power Station provides a cleaner source of power generation for Mount Isa with lower emissions and higher plant efficiencies than traditional coal-fired power plants. It produces electricity to supply mines and local communities, with scope for further expansion as energy demand increases.

The Mount Isa region is not connected to the National Electricity Market (NEM) and is located approximately 1,000 kilometres from the nearest potential NEM connection point. The region relies on a local distribution network with centralised gas-fired power generation and on-site generation for remote mining sites. Gas is supplied to the region via APA’s Carpentaria Gas Pipeline.
