The Los Angeles Department of Water and Power (LADWP), joined by elected officials, regulatory and environmental leaders, broke ground on a $950 million repowering project at the Scattergood Generating Station in Playa Del Rey that will reduce - and is a major first step toward eliminating -ocean water cooling, reduce emissions, and improve power reliability and integration with renewable energy.
The Scattergood Generating Station Repowering Project will replace the existing Unit 3 with a highly efficient combined cycle (natural gas and steam) turbine and two simple-cycle turbines. Both the combined-cycle and the simple-cycle turbines have fast start and ramp-up capabilities for short-term increases in electrical demand and for more flexible integration of renewable energy.
The new generating units will be 33% more fuel efficient than the existing Unit 3 and feature advanced pollution control systems, thereby reduce emissions of air pollutants and greenhouses gases. The project will also greatly reduce harmful impacts on marine habitat by replacing the current ocean cooling system at Unit 3 with an air-cooled condenser for the combined-cycle unit and an air-cooled heat exchanger for the smaller simple-cycle units.
