Goose Creek Energy Center: 684 MW Gas Power Plant in Illinois, United States

Goose Creek Energy Center is a gas-fired power generation facility located in Illinois, United States. With a capacity of 684 megawatts, it operates as a medium-to-large scale plant within the US power generation sector. The facility is owned and operated by Union Electric Co, a utility serving the Missouri region. The plant utilizes natural gas as its primary fuel, a common choice for modern power generation due to its lower emissions compared to coal. As a gas-fired plant, it likely employs combined-cycle or simple-cycle technology, which offers operational flexibility and efficiency. The facility operates under the regulatory framework of the US Environmental Protection Agency, including the Clean Air Act and associated programs such as the Acid Rain Program and the Cross-State Air Pollution Rule. Goose Creek Energy Center plays a role in meeting the electricity demands of the surrounding region. Its location in Illinois places it within a state with a diverse energy mix, including nuclear, coal, and renewables. The plant contributes to grid reliability and supports the transition toward cleaner natural gas generation.

The plant's use of natural gas results in lower carbon dioxide emissions per megawatt-hour compared to coal-fired plants, but it still contributes to greenhouse gas emissions. Its location in a rural area of Illinois reduces direct exposure to densely populated centers, though regional air quality may be affected by nitrogen oxides and other pollutants. Modern gas plants typically incorporate emissions control technologies to meet EPA standards.
