Siemens Energy has received an order from Australia for the supply of two steam turbines and four gas turbines for the Diamantina  Power Station Pty Ltd. combined cycle power station. Purchaser for the plant in Mount Isa in the state of Queensland is CTEC, a provider of energy-efficient solutions headquartered in Perth. Following commissioning of the combined cycle plant scheduled for early 2014, the installed capacity of 242 megawatts (MW) will be sufficient to supply ecofriendly electricity to local mines operated by Xstrata and to people living in the region. The order volume for Siemens is over EUR150 million.

The Diamantina combined cycle power station in Mount Isa is being built adjacent to the existing Mica Creek station. Siemens will be responsible for the overall plant design and will also provide technical advisory services during the construction and commissioning phases of the project. The Siemens scope of supply encompasses two power islands each comprising one SST-400 steam turbine, two SGT-800 gas turbines and two heat-recovery steam generators (HRSG). The Diamantina Power Station will be a 242 MW combined cycle power station, set out in a configuration of two 121 MW power blocks. Diamantina is expected to be fully operational in early 2014, with the first block available in late 2013 and the second block available in early 2014.
