Chaoyang Yanshanhu Power Station: 1,200 MW Coal Power Plant in Chaoyang, China

Chaoyang Yanshanhu power station is a coal-fired power plant located in Chaoyang, Liaoning Province, China. With a capacity of 1,200 MW, it is a large-scale facility within China's extensive coal power fleet, which remains a cornerstone of the country's energy mix. The plant is owned and operated by CPI Northeast Power Co Ltd, a subsidiary of State Power Investment Corporation. The plant operates under China's national emission standards for thermal power plants, which include limits on SO2, NOx, and particulate matter. China has been progressively tightening emission regulations and promoting the adoption of advanced technologies like ultra-supercritical and circulating fluidized bed combustion to improve efficiency and reduce pollution. Environmentally, the plant's coal combustion contributes to CO2 emissions and local air pollutants. Its location in Chaoyang, a city in Liaoning Province, places it in a region with significant industrial activity and coal-dependent energy infrastructure. The plant plays a key role in meeting local electricity demand, but also faces scrutiny under China's evolving environmental policies aimed at reducing coal reliance and transitioning to cleaner energy sources.

The plant's coal fuel source results in substantial CO2, SOx, and NOx emissions, typical of coal-fired generation. Its location in Chaoyang, Liaoning, an area with existing industrial pollution, may contribute to local air quality concerns. The facility's age and technology (likely subcritical or supercritical) influence its thermal efficiency and emission intensity. China's regulatory framework, including the Air Pollution Prevention and Control Action Plan, imposes emission limits and encourages retrofits for existing plants.
