Siemens To Provide Power Islands To NRG Energy

Posted on September 9, 2010

Siemens Energy has received an order from U.S.A. power company NRG Energy to supply two SCC6-5000F Flex-Plant 10 combined cycle power islands in El Segundo, California, U.S.A. The two power islands, which feature fast-start technology, low start up emissions and water usage, can generate 300 MW within 10 minutes.

Siemens’ scope of supply includes the main power island components, such as the SGT6-5000F gas turbine generator, an SST-800 steam turbine generator, a heat recovery steam generator and an air-cooled condenser. Siemens will also provide the electrical, power plant instrumentation and control systems, as well as the engineering services and commissioning of the plant, said the company.

The SGT6-5000F, which is integrated with a single-pressure, non-reheat bottoming cycle, sits at the heart of the Flex-Plant 10. Coupled with an air-cooled heat exchanger for steam condensing, the Flex-Plant 10 provides a net efficiency of nearly 49%, Siemens said.

Once the power islands go online in the spring of 2013, they will be able to power 240 000 households.
