Limon Generating Station - Gas Power Plant in Colorado, USA

Limon Generating Station is a gas-fired power plant located in Colorado, United States, with a capacity of 154.2 megawatts. The facility is owned by Tri-State G & T Assn Inc and is currently operational, contributing to the region's electricity supply. As a gas power plant, Limon Generating Station utilizes natural gas as its primary fuel, a common choice for flexible and relatively lower-emission power generation. The plant 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 (CSAPR), which set emission limits for sulfur dioxide, nitrogen oxides, and other pollutants. The plant's capacity of 154.2 MW places it in the medium-scale range for gas power plants in the United States. Its location in Colorado supports the local grid, providing reliable power to the surrounding area. The facility's operational status ensures continued contribution to the energy mix, with natural gas offering a balance between efficiency and environmental impact.

The Limon Generating Station's use of natural gas results in lower carbon dioxide emissions per megawatt-hour compared to coal-fired plants, but still contributes to greenhouse gas emissions. The plant's location in a relatively rural area of Colorado reduces direct exposure to densely populated zones, though regional air quality may be affected by NOx and SOx emissions. Typical gas plants of this scale employ combined cycle or simple cycle turbines, with varying efficiency and emission profiles.
