Oak Grove (TX) Coal Power Plant | Texas, United States

Oak Grove (TX) is a coal-fired power plant located in Texas, United States, with a capacity of 1,795.4 MW. Owned and operated by Luminant Generation Company LLC, the facility plays a significant role in the state's energy mix, providing baseload power to the ERCOT grid. As a large-scale coal plant, it is among the larger units in the region. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) with National Ambient Air Quality Standards (NAAQS), the Acid Rain Program, and the Cross-State Air Pollution Rule (CSAPR). These regulations govern emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. The plant's coal-fired technology, while efficient at its scale, is subject to these stringent environmental standards. Oak Grove (TX) serves a critical function in ensuring grid reliability and meeting the electricity demands of Texas's growing population and industrial base. Its operational status and capacity contribute to the stability of the regional power supply. The facility's environmental performance is monitored under EPA programs, and its coal fuel source places it within the context of ongoing energy transition discussions in the United States.

The plant's coal fuel source results in significant CO2, SO2, and NOx emissions compared to natural gas or renewable sources. Its location in Texas, a state with high energy demand and a mix of fossil and renewable generation, means the plant operates in a region with varying air quality standards. The facility's age and technology (likely subcritical or supercritical) influence its thermal efficiency and emission profile.
