Intermountain Power Project: 1,640 MW Coal Power Plant in Utah, USA

Intermountain Power Project is a large coal-fired power plant located in Utah, United States, with a capacity of 1,640 MW. Owned by the Los Angeles Department of Water & Power, the facility is operational and plays a significant role in the region's power generation mix. As a coal plant, it operates under the regulatory framework of the US EPA, including the Clean Air Act, NAAQS, and the Acid Rain Program. The plant's technology is typical of large-scale coal generation, with subcritical or supercritical boilers common for its era. It is subject to emissions limits for SOx, NOx, and particulate matter under CSAPR and other federal rules. The facility's location in Utah places it in a region with a mix of coal and natural gas generation, and it contributes to the power supply for Los Angeles and surrounding areas. Environmentally, the plant's coal fuel source results in significant CO2 emissions, and its proximity to populated areas may raise local air quality concerns. The facility's age and technology influence its efficiency and emissions profile. Despite these factors, it remains a key asset for grid reliability and baseload power in the western US.

The Intermountain Power Project, as a coal-fired plant, has a substantial environmental footprint due to CO2, SOx, and NOx emissions. Its location in Utah, near the Great Basin, may affect local air quality and ecosystems. The plant's age and technology (likely subcritical) result in lower efficiency and higher emissions per MWh compared to modern natural gas plants. Regulatory compliance with US EPA standards helps mitigate some impacts, but coal generation remains a significant source of greenhouse gases and pollutants.
