Huaneng Yueyang Power Station - 2,524 MW Coal Power Plant in Yueyang, China

Huaneng Yueyang power station is a large coal-fired power plant located in Yueyang, Hunan Province, China. With a capacity of 2,524 MW, it ranks among the significant coal power facilities in the country, contributing to the regional grid's baseload power supply. The plant is owned and operated by China Huaneng Group Corporation (CHNG), one of China's major state-owned power generation enterprises. The plant utilizes coal as its primary fuel, a common choice in China's power sector due to abundant domestic coal reserves. While specific technology details (subcritical, supercritical, or ultra-supercritical) are not disclosed, many Chinese coal plants of this scale employ advanced supercritical or ultra-supercritical boilers to improve efficiency and reduce emissions. The facility operates under China's national emission standards for thermal power plants, which have become increasingly stringent in recent years, including limits on SO2, NOx, and particulate matter. Environmental considerations for this plant include its coal fuel source, which results in significant CO2 emissions and local air pollutants. Its location in Yueyang, a city in Hunan province, places it in a region with moderate population density. Older coal plants typically have higher emission intensities. As part of China's efforts to transition to cleaner energy, coal plants like Huaneng Yueyang may face pressure to retrofit with pollution control equipment or reduce operating hours.

The plant's coal combustion produces substantial CO2 emissions, contributing to climate change, as well as SOx, NOx, and particulate matter that can affect local air quality. Yueyang's location near Dongting Lake and the Yangtze River means the plant's water usage and thermal discharge could impact aquatic ecosystems. Proximity to populated areas raises concerns about public health impacts from air pollution. The facility's environmental performance depends on its emission control technologies, such as flue gas desulfurization and selective catalytic reduction, which are common in modern Chinese coal plants.
