The utility is planning to phase out Scattergood’s 460MW Unit 3 conventional steam boiler, and replace it with GE’s ecomagination qualified advanced combined-cycle power island with "Rapid Response" technology.
The technology will feature a 216-MW 7F.05 gas turbine, a GE ST-A650 steam turbine operating in combined-cycle mode and a heat recovery steam generator.
Additional components include two ecomagination qualified 104MW intercooled LMS100 aeroderivative gas turbines, and GE’s modern distributed control system (DCS) for monitoring and control of the new power generation equipment.
LADWP Power System senior assistant general manager Aram Benyamin said the older units take whole day to reach full power, causing the company to lose the window of opportunity it has to capture electricity produced by wind.
"With the GE technology generating power, we can achieve the intricate balancing act required to maintain a steady flow of power to our customers," Benyamin added.
GE Power & Water Power Generation Products president and CEO Victor Abate said, "With the ability to ramp up fast when it’s needed and turn down when it’s not, GE’s advanced technology will help the utility balance the grid, utilize natural gas to expand the role of renewables and better meet its pressing energy and environmental challenges."
Equipment production will take place at the company’s facilities in South Carolina, New York, and Texas, US, while commercial operation of the Scattergood station’s new power generating equipment is scheduled to start by the end of 2015.
