Generation Station Up And Running

Siemens Fast-Start technology minimizing transient emissions while ramping

Posted on June 20, 2013


The Marsh Landing Generating Station, located in Antioch, California, U.S.A., has commenced commercial operations utilizing Siemens technology.

The end customer is U.S. power supply company NRG Energy, Inc. The gas-fueled power plant, about 64 km northeast of San Francisco, can provide up to 720 MW of flexible electrical generation to the California grid, which is enough to supply 650 000 homes.

Siemens supplied four SGT6-5000F gas turbines, four SGen-1000A generators, the SPPA-T3000 control system, and auxiliary and secondary systems, as well as providing technical support with installation and commissioning.

During commissioning, Siemens said the capability for all four F-Class turbines to ramp up reliably to the full load of 720 MW in 12 minutes was demonstrated, further substantiating the company’s Fast-Start capability.

The company said that the Fast-Start technology employed by Marsh Landing also supports the integration of new renewable energy sources that are expected to come online over the next decade.
