King City Power Plant: 133.2 MW Gas Power Plant in California, USA

King City Power Plant is a gas-fired power generation facility located in California, United States. With a capacity of 133.2 MW, it falls within the medium-scale range for gas power plants in the region. The plant is owned by Calpine King City Cogen LLC and is currently operational. The facility 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 plant, it benefits from lower emissions of sulfur dioxide (SOx) and particulate matter compared to coal-fired plants, but still must comply with emissions limits for nitrogen oxides (NOx) and carbon monoxide. The plant's technology likely includes combined cycle or simple cycle gas turbines, typical for modern gas power plants. King City Power Plant plays a role in supplying electricity to the local grid in California, a state with ambitious renewable energy goals and stringent environmental regulations. Its location in a rural area may reduce direct population exposure to emissions, but the plant contributes to the state's overall energy mix and supports grid reliability.

The plant's gas-fired operation results in lower CO2, SOx, and NOx emissions per MWh compared to coal or oil plants, but still contributes to greenhouse gas emissions. Located in California, the facility must comply with state-level cap-and-trade programs and the EPA's Cross-State Air Pollution Rule (CSAPR). Proximity to agricultural areas may influence local air quality considerations, though the plant's medium capacity and modern technology likely incorporate best available control technologies (BACT) for emissions reduction.
