Pastoria Energy Facility LLC - 779 MW Gas Power Plant in California, United States

Pastoria Energy Facility LLC is a gas-fired power plant located in California, United States, with a capacity of 779 megawatts. The facility is owned and operated by Calpine Corp and is currently operational, contributing to the state's power generation mix. The plant operates under the regulatory framework of the US Clean Air Act, including NAAQS and the Acid Rain Program, which govern emissions of SOx, NOx, and other pollutants. As a gas-fired plant, it typically has lower CO2 and pollutant emissions compared to coal-fired units, and its capacity places it in the medium-to-large scale for gas plants in the US. The facility plays a role in meeting California's electricity demand, supporting grid reliability. Its location in California subjects it to state-specific environmental regulations, including those under the California Air Resources Board, which may impose additional emission controls.

The plant's gas fuel type results in lower CO2, SOx, and NOx emissions per MWh compared to coal. Its location in California, a state with stringent air quality standards, means it likely operates with advanced emission controls. The 779 MW capacity indicates a significant local environmental footprint, but gas plants generally have a lower environmental impact than other fossil fuel plants.
