Midway Sunset Cogen Gas Power Plant, California, United States

Midway Sunset Cogen is a gas-fired power plant located in California, United States, with a capacity of 234 megawatts (MW). The plant is owned by Midway-Sunset Cogeneration Co and is currently operational. As a gas power plant, it contributes to the region's electricity generation mix, which is increasingly focused on cleaner energy sources. The plant operates under the regulatory framework of the United States Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and its associated programs such as the National Ambient Air Quality Standards (NAAQS) and the Acid Rain Program. Gas-fired plants like Midway Sunset Cogen typically have lower emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) compared to coal-fired plants, but still require compliance with emission limits and monitoring requirements. Midway Sunset Cogen plays a role in the local power grid, providing reliable electricity to the surrounding area. Its location in California, a state with ambitious renewable energy goals, means it may operate alongside solar and wind resources. The plant's cogeneration capability likely enhances its efficiency by capturing waste heat for industrial or other uses, reducing overall environmental impact.

The plant's gas-fired technology results in lower CO2 emissions per megawatt-hour compared to coal, but still contributes to greenhouse gas emissions. Its location in California, a state with stringent air quality regulations, means it must comply with the California Air Resources Board (CARB) rules. The plant's proximity to populated areas could raise local air quality concerns, though modern gas plants are equipped with advanced emission controls.
