Overview
Pacific Ethanol Stockton Cogen Plant is a 4.8 MW gas-fired cogeneration facility in Stockton, California, United States. It provides both electricity and thermal energy for industrial processes.
Pacific Ethanol Stockton Cogen Plant is a gas-fired cogeneration facility located in Stockton, California, United States. With a capacity of 4.8 MW, it is a small-scale power plant that operates as a combined heat and power (CHP) unit, supplying electricity and thermal energy to the adjacent ethanol production facility. The plant is owned by Pacific Ethanol Stockton and is currently operational. The plant uses natural gas as its primary fuel, a cleaner-burning fossil fuel compared to coal or oil. As a cogeneration facility, it achieves higher overall efficiency by capturing waste heat for industrial use. In the United States, such facilities are subject to federal and state environmental regulations, including the Clean Air Act and California's stringent emissions standards. The plant's small capacity and modern technology likely help it maintain compliance with these regulations. This facility plays a key role in supporting local ethanol production, contributing to the region's renewable fuel supply chain. Its location in Stockton, a major agricultural and industrial hub in California's Central Valley, allows it to serve both energy and industrial needs efficiently. The plant's cogeneration design reduces overall fuel consumption and emissions compared to separate heat and power generation.
Environmental context
The Pacific Ethanol Stockton Cogen Plant uses natural gas, which produces lower CO2, SOx, and NOx emissions compared to coal or oil. Its small capacity (4.8 MW) and cogeneration design minimize environmental footprint by utilizing waste heat. Located in Stockton, California, the plant operates in an area with strict air quality regulations under the California Air Resources Board and the US EPA's Clean Air Act. The facility's proximity to agricultural and urban areas necessitates adherence to local emission standards to protect public health and the environment.
Frequently asked questions
Pacific Ethanol Stockton Cogen Plant is located in Stockton, California, United States, at coordinates 37.941800 N, -121.338300 W.
It is a gas-fired cogeneration plant that produces both electricity and thermal energy, primarily supporting an ethanol production facility.
The plant has a capacity of 4.8 megawatts (MW), classifying it as a small-scale power generation facility.
Gas-fired power plants in California must comply with the US EPA's Clean Air Act, including National Ambient Air Quality Standards (NAAQS), and state-level regulations from the California Air Resources Board (CARB), which impose strict limits on NOx, SOx, and other pollutants.
Cogeneration, or combined heat and power (CHP), captures waste heat for industrial use, increasing overall efficiency to 60-80% compared to 35-40% for separate generation. This reduces fuel consumption, greenhouse gas emissions, and other pollutants.
