Siemens has completed the commissioning of two combined-cycle power blocks that are used to supply power to mines operated by Glencore in the Mount Isa region in the state of Queensland, Australia.

The owner and operator of the plant (pictured), Diamantina Power Station Pty Limited, is a joint venture between APA Group and AGL Energy Limited.

With a total capacity of 242 MW, Siemens was responsible for the overall plant design as well as supplying two power islands, each comprising two SGT-800 gas turbines, two heat-recovery steam generators (HRSG) with diverter dampers – both supplied by NEM Energy b.v. – as well as one SST-400 steam turbine connected to the local grid.

‘Diamantina power station is a great example of our eco-friendly power generation solutions for island off-grid operation matching the variable power demand of the adjacent copper mine,’ said Erling Bruun, head of Industrial Power Plant Solutions in Siemens’ Power and Gas Division.

David Jones, General Manager Development of the APA Group, added: ‘This plant meets the challenging demands of island operation and load flexibility.’
