King City Peaking Gas Power Plant | King City, California, USA

King City Peaking is a natural gas-fired power plant located in King City, California, United States. With a capacity of 47.3 MW, it is classified as a small-scale peaking plant, designed to operate during periods of peak electricity demand. The facility is owned and operated by Calpine Corp, a major independent power producer in the US. The plant operates under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and its National Ambient Air Quality Standards (NAAQS). As a gas-fired peaking plant, it typically uses simple-cycle or combined-cycle technology, though specific configuration is not detailed. Peaking plants generally have lower capacity factors but higher emissions per MWh compared to baseload plants. King City Peaking plays a crucial role in maintaining grid stability in California's electricity market, particularly during heatwaves or when renewable generation is low. Its location in Monterey County serves local communities and supports the broader California Independent System Operator (CAISO) grid. The plant's relatively small size and gas fuel type result in a moderate environmental footprint compared to coal-fired alternatives.

The plant's gas fuel type produces lower CO2 emissions per MWh than coal but still contributes to greenhouse gas emissions. Its location in a rural area of California reduces direct population exposure to pollutants. However, as a peaking plant, it may operate during high-demand periods when air quality conditions are already stressed. The facility must comply with California's stringent air quality regulations, including the state's cap-and-trade program and local air district rules.
