Lake Hubbard Gas Power Plant: 927.5 MW Facility in Texas, USA

Lake Hubbard is a gas-fired power plant located in Texas, United States, with a generating capacity of 927.5 MW. The facility is owned and operated by Luminant Generation Company LLC and is currently in operational status. As a gas power plant, it contributes to the regional electricity grid, serving industrial and residential customers. The plant operates under the regulatory framework of the US 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 Cross-State Air Pollution Rule (CSAPR). Gas-fired plants like Lake Hubbard typically use combined cycle or simple cycle technology, with modern units achieving higher efficiency and lower emissions compared to older coal-fired plants. Lake Hubbard plays a significant role in the Texas power market, which is managed by the Electric Reliability Council of Texas (ERCOT). The plant's gas-fired generation provides flexible and reliable power, supporting grid stability during peak demand periods. Its location in Texas, a state with a diverse energy mix, underscores its importance in the transition towards cleaner natural gas generation.

The plant's gas-fired operation results in lower CO2, SOx, and NOx emissions compared to coal-fired plants, but still contributes to greenhouse gas emissions. Its location in Texas, a region with growing population and industrial activity, means the plant's emissions are subject to EPA regulations to protect air quality. The facility's capacity of 927.5 MW places it in the large-scale category, and its age and technology (likely combined cycle) influence its environmental footprint.
