Maanshan Steel power station - Coal Power Plant in Maanshan, China

Maanshan Steel power station is a coal-fired power plant located in Maanshan, Anhui Province, China. With a capacity of 375 MW, it is a medium-sized facility that primarily serves the energy needs of the Maanshan Iron & Steel Co Ltd steelworks, one of the largest steel producers in the region. The plant is operational and plays a key role in supporting industrial activities in the area. The plant uses coal as its primary fuel, a common choice for industrial power generation in China. While specific technology details (e.g., subcritical or supercritical) are not disclosed, many Chinese coal plants of this era employ subcritical technology. The facility operates under China's national emission standards for thermal power plants, which have become increasingly stringent in recent years, requiring desulfurization, denitrification, and particulate control systems. As a captive power plant for a steel mill, Maanshan Steel power station contributes to the energy security of the industrial complex. However, coal-fired generation in China faces environmental scrutiny due to CO2 emissions and local air quality impacts. Its continued operation reflects the ongoing reliance on coal for heavy industry in China.

The plant's coal combustion produces CO2, SOx, NOx, and particulate matter, contributing to local air pollution and greenhouse gas emissions. Its location in an industrial zone near Maanshan city may expose surrounding populations to emissions. Chinese regulations require coal plants to meet emission limits for SO2, NOx, and particulates, often achieved through flue-gas desulfurization and selective catalytic reduction. The plant's age and technology (likely subcritical) may result in lower efficiency and higher emissions per MWh compared to modern supercritical or ultra-supercritical units.
