Siemens Wins Order for Two Flex-Plant(TM) 10 Combined Cycle Power Islands

ORLANDO, Fla. - Siemens Energy has been awarded its first order for the supply of two SCC6-5000F Flex-Plant 10 combined cycle power islands. The order for the two power islands in El Segundo, California, comes from the U.S. power company NRG Energy. The advanced design of the Flex-Plant 10 offers an environmentally compatible solution for the peaking to intermediate market through fast-start technology, and low start-up emissions and water usage. The two Flex-Plant 10 power islands can generate an output of 300 megawatts (MW) within 10 minutes. When the plant goes online in the spring of 2013, these units will be able to supply environmentally friendly power to 240,000 households.

At the heart of the Flex-Plant 10 is the SGT6-5000F gas turbine, integrated with a single-pressure, non-reheat bottoming cycle. Together with an air-cooled heat exchanger for steam condensing, the Flex-Plant 10 provides a net efficiency of nearly 49 percent, making it the most efficient peaking plant technology available today. Compared to a traditional simple cycle plant, and because of its higher efficiency and low water consumption, the Flex-Plant 10 is the most competitive solution for peak- to intermediate-duty cycles, including the 10-minute non-spinning reserve market.

The natural gas-fueled power plant in El Segundo will have a nominal rating of 560 MW. The Siemens scope of supply includes the main power island components - each featuring a SGT6-5000F gas turbine-generator, an SST-800 steam turbine-generator, a heat recovery steam generator and an air-cooled condenser - along with the complete electrical and power plant instrumentation and control systems. Siemens also will provide the engineering services and commissioning of the plant.

"Our Flex-Plant peakers are specifically designed to meet the U.S. market needs for extremely short start-up times and delivery of high efficiency and low emissions. We are proud to be working with NRG to launch the Flex-Plant 10, making their company the first to have the benchmark for peak- to intermediate-duty range power plants in its portfolio," says Michael Suess, CEO of the Fossil Power Generation Division at Siemens Energy.

"The Siemens Flex 10 technology provides the California grid what is needed to meet aggressive environmental goals," said Steve Hoffmann, President of NRG's West Region. "The fast-start features help firm intermittent renewable resources while the high efficiency meets new clean air standards."

Flex-Plant 10 plants 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 eco-friendly 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:
