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.

"Diamantina power station is a great example of our ecofriendly power supply solutions for different industries worldwide,” said Markus Tacke, CEO of the Industrial Power Business Unit of Siemens Energy. “With its high-efficiency gas and steam turbines, Siemens helps to minimize the environmental impact of industrial power generation."

High-efficiency combined cycle power plants are part of Siemens’ Environmental Portfolio. In fiscal 2011, revenue from the Portfolio totaled about €30 billion, making Siemens one of the world’s largest suppliers of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by nearly 320 million tons, an amount equal to the total annual CO2 emissions of Berlin, Delhi, Hong Kong, Istanbul, London, New York, Singapore and Tokyo.

The Siemens Energy Sector is the world’s leading supplier of a complete spectrum of products, services and solutions for power generation in thermal power plants and using renewables, power transmission in grids and for the extraction, processing and transport of oil and gas. In fiscal 2011 (ended September 30), the Energy Sector had revenues of EUR24.9 billion and received new orders totaling approximately EUR31.8 billion and posted a profit of EUR3.9 billion. On October 1, 2011, the Energy Sector had a work force of more than 82,000. Further information is available at:
