Featuring two combined cycle power blocks, the Diamantina power plant is owned and operated by Diamantina Power Station, a joint venture between APA Group and AGL Energy and is considered as one of Australia’s most efficient industrial power stations.

Located in Mount Isa in the state of Queensland and adjacent to the existing Mica Creek power station, the facility has been designed to supply ecofriendly electricity to local mines operated by Glencore and people in the region.

In addition to designing, Siemens provided technical advisory services during the construction and commissioning phases of the project.

Siemens has also been responsible for the supply of two power islands each comprising two SGT-800 gas turbines, two heat-recovery steam generators(HRSG) with diverter dampers as well as one SST-400 steam turbine connected to the local grid through 132kV electrical switchyard.

Siemens Power and Gas Division industrial power plant solutions head Erling Bruun said: "Diamantina power station is a great example of our ecofriendly power generation solutions for island off grid operation matching the variable power demand of the adjacent copper mine."

Maintenance service will be provided for the SGT-800 Gas Turbines, SST-400 steam turbines, generators and the related control and auxiliary systems by Siemens under a long term services agreement.

APA Group development general manager David Jones said: "This plant meets the challenging demands of island operation and load flexibility, in combination with bringing a high efficiency and state-of-the-art low emission technology and solutions."
