Johnson County Gas Power Plant | Texas Power Generation Facility

Johnson County is a gas-fired power generation facility located in Texas, United States, with a capacity of 282.6 megawatts. Owned by Brazos Electric Power Coop Inc, the plant is operational and contributes to the regional power supply. As a gas plant, it represents a significant portion of the state's energy mix, which relies heavily on natural gas for electricity generation. The plant operates under the regulatory oversight of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as the National Ambient Air Quality Standards (NAAQS) and the Cross-State Air Pollution Rule (CSAPR). Gas-fired plants like Johnson County typically employ combined cycle or simple cycle technology, with modern facilities achieving higher efficiency and lower emissions compared to older coal-fired units. The specific technology type for this plant is not detailed, but gas plants in this capacity range often use combined cycle configurations. Johnson County plays a role in meeting the electricity demands of the surrounding region, including residential, commercial, and industrial customers. As a gas plant, it has a lower carbon footprint relative to coal but still contributes to greenhouse gas emissions. The plant's location in Texas, a state with a competitive electricity market, underscores its importance in providing reliable power generation. Environmental considerations include compliance with emission limits for NOx, SO2, and CO2, as well as local air quality management.

The plant's gas fuel type results in lower CO2, SOx, and NOx emissions compared to coal, but still contributes to regional air quality concerns. Texas has a diverse energy mix, and gas plants like Johnson County are subject to EPA regulations under the Clean Air Act. The facility's capacity of 282.6 MW places it in the medium-scale range for gas plants, with typical environmental oversight including emissions monitoring and reporting.
