Huaneng Dalian power station - 1,400 MW Coal Power Plant in Dalian, China

Huaneng Dalian power station is a coal-fired power plant located in Dalian, Liaoning Province, China. With a capacity of 1,400 MW, it is a large-scale facility within China's extensive coal power fleet, which dominates the country's electricity generation mix. The plant is owned by China Huaneng Group Corporation (CHNG), one of the largest state-owned power generation companies in China. As a coal-fired plant, Huaneng Dalian operates under China's national emission standards for thermal power plants, which include limits on SO2, NOx, and particulate matter. The plant likely utilizes conventional pulverized coal combustion technology, typical for facilities of its era. China has been progressively tightening emission regulations and promoting the adoption of advanced technologies such as supercritical and ultra-supercritical boilers to improve efficiency and reduce pollution. The plant plays a significant role in meeting the electricity demand of Dalian, a major port and industrial city in Liaoning Province. Its operation contributes to the local grid stability but also involves environmental considerations due to coal combustion emissions. The facility is part of China's broader energy infrastructure, which is undergoing a transition toward cleaner energy sources while still relying heavily on coal for baseload power.

The plant's coal combustion produces CO2, SO2, NOx, and particulate matter, contributing to local air quality concerns and greenhouse gas emissions. Dalian's coastal location may influence dispersion patterns. Proximity to urban areas heightens potential health impacts. China's regulatory framework, including the Air Pollution Prevention and Control Action Plan, imposes emission limits and encourages retrofitting with pollution control technologies such as flue-gas desulfurization and selective catalytic reduction.
