NRG Energy has awarded Siemens Energy its first order for the supply of two SCC6-5000F Flex-Plant 10 combined-cycle power islands for its natural gas-fueled power plant in El Segundo, California. 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 300MW 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. Flex-Plant 10 plants are part of Siemens’ Environmental Portfolio. 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 will also provide the engineering services and commissioning of the plant.
