Dry Fork Station: 483.7 MW Coal Power Plant in Wyoming, USA

Dry Fork Station is a coal-fired power plant located in Wyoming, United States, with a generating capacity of 483.7 megawatts. Owned and operated by Basin Electric Power Cooperative, the facility plays a key role in the region's energy mix, providing baseload power to the grid. The plant is situated in a sparsely populated area, typical of many coal facilities in the western US. The plant operates under the regulatory framework of the US Clean Air Act, including the Acid Rain Program and the Cross-State Air Pollution Rule (CSAPR). As a coal-fired facility, it is subject to emission limits for sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. Dry Fork Station contributes to the reliability of the regional power system, serving member cooperatives across several states. Its location in Wyoming, a major coal-producing state, aligns with the local industrial context. The plant's environmental footprint includes CO2 emissions typical of coal generation, but its remote siting reduces direct population exposure.

The plant's coal fuel source results in significant CO2 emissions per MWh compared to natural gas or renewables. Its location in a rural area minimizes direct impact on populated zones, but regional air quality may be affected by SO2 and NOx emissions. The facility's age and technology (likely subcritical) imply lower efficiency and higher emission rates than modern supercritical or CCGT plants.
