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 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 the 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 MW and boosting the station’s overall capacity to 333 MW” said Markus Tacke, CEO of Siemens’ Industrial Power business unit.
