The plant comprises two combined cycle power blocks able to run at in excess of 50% efficiency. It is owned and will be operated by Diamantina Power Station Pty Ltd, a joint venture between APA Group and AGL Energy Ltd.

Total installed capacity is 242 MW set out as two blocks of 121 MW. Siemens was responsible for the overall plant design, as well as technical advisory services through construction and commissioning. Its scope of supply included two power islands consisting of two SGT-800 gas turbines and two heat-recovery steam generators with diverter dampers – both supplied by NEM Energy b.v. – as well as one SST-400 steam turbine connected to the local grid via 132kV electrical switchyard.

Siemens will also provide maintenance for the SGT-800 gas turbines, SST-400 steam turbines, generators and the related control and auxiliary systems under a long-term services agreement.

"Diamantina power plant 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," said Erling Bruun, Head of Industrial Power Plant Solutions in Siemens Power and Gas Division.
