Barney M Davis Gas Power Plant | Texas, United States

Barney M Davis is a gas-fired power plant located in Texas, United States, with a capacity of 1,082.2 MW. The facility is owned by Talen Texas LLC and is currently operational, serving as a significant source of electricity generation in the region. As a gas power plant, Barney M Davis utilizes natural gas as its primary fuel, which typically results in lower emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) compared to coal-fired plants. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as the Acid Rain Program and the Cross-State Air Pollution Rule (CSAPR). These regulations set emission limits and require monitoring to ensure compliance. The facility's capacity of over 1,000 MW places it in the large-scale category for gas power plants. Its operation supports grid reliability and meets electricity demand in Texas, which has a diverse energy mix. The plant's environmental footprint is influenced by its fuel type and technology, with modern combined-cycle gas turbine (CCGT) plants achieving higher efficiency and lower emissions than older designs.

The plant's gas fuel type results in lower CO2 emissions per MWh compared to coal, but still contributes to greenhouse gas emissions. Its location in Texas, a state with significant oil and gas production, means the facility operates within a region with established infrastructure for natural gas supply. Proximity to populated areas may influence local air quality considerations, but the plant's compliance with EPA regulations helps mitigate environmental impacts.
