Document Description
SCE is proposing to build a small electricity generating unit called a "peaker" that will be capable of producing up to 45 MW of electricity on short notice during periods when the local electrical system needs power and local voltage support. The peaker unit has blackstart capability and consists of a state-of-the-art General Electric natural gas-fired turbine generator plus a selective catalytic reduction system and an oxidation catalyst to reduce emissions to levels that meet or exceed all applicable local air quality emission standards. This peaker project will be located on existing SCE property adjacent to the Etiwanda substation in the City of Rancho Cucamonga. SCE chose this location because a natural gas supply line was nearby and because SCE was directed to site this peaker where it would provide the additional electricity supply and voltage support for the grid most efficiently. The proposed project is expected to create significant adverse impacts to air quality during the construction phase but the impacts will be mitigated to less than significant. No other environmental topic areas will generate potential significant impacts.
