Siemens to Supply Power Island Equipment to California

Siemens Energy has received an order to supply the power island for the repowering of El Centro Generating Station Unit 3 in California. ARB, Inc., a multinational construction company, will be the EPC contractor for the facility. Operator and owner of the power plant is Imperial Irrigation District (IID), California's third largest public power provider.

Construction will begin on the project in mid-2010, with commercial operation anticipated to commence in May 2012. The Siemens scope of supply for this repowering project will encompass the power island, including two SGT-800 gas turbines and an SST-600 steam turbine-generator installed in a combined-cycle configuration, together with two heat-recovery steam generators and a condenser. Siemens will also provide state-of-the-art NOx and CO emissions controls systems that meet best available control technology requirements.

"Repowering of this unit will replace equipment installed more than fifty years ago with Siemens state-of-the-art power island equipment, increasing overall output by 100 megawatts (MW) and boosting the station's overall capacity to 333 MW" said Markus Tacke, CEO of the Industrial Power Business Unit of Siemens Energy. "Repowering a generation unit involves replacing or substantially upgrading the equipment with advanced technology to improve its efficiency and environmental performance."

Power plant modernizations are part of Siemens' Environmental Portfolio. In fiscal 2009, revenue from the Portfolio totaled about EUR23 billion, making Siemens the world's largest supplier of ecofriendly technologies. In the same period, the company's products and solutions enabled customers to reduce their CO2 emissions by 210 million tons. This amount equals the combined annual CO2 emissions of New York, Tokyo, London and Berlin.

The Siemens Energy Sector is the world's leading supplier of a complete spectrum of products, services and solutions for the generation, transmission and distribution of power and for the extraction, conversion and transport of oil and gas. In fiscal 2009 (ended September 30), the Energy Sector had revenues of approximately EUR25.8 billion and received new orders totaling approximately EUR30 billion and posted a profit of EUR3.3 billion. On September 30, 2009, the Energy Sector had a work force of more than 85,100. Further information is available at:
