Two Southern California Edison Co.(SCE) natural gas-fired hybrid peaking generation plants with integrated battery storage were cited by the South Coast Air Quality Management District(SCAQMD) for innovative clean air technology that has resulted in a 60% reduction in greenhouse gas and particulate matter emissions. The hybrid system produces the reduction by allowing each turbine to operate in standby mode without combusting fuel. The battery storage allows for an immediate response to changing energy dispatch needs, according to the Rosemead, CA-based utility and SCAQMD. The result was attained through a three-way partnership among SCE, General Electric, and a selective catalytic reduction provider, Wellhead Power Solutions.
