Castle Peak power station - 4,108 MW Coal Power Plant in Hong Kong, China

Castle Peak power station is a major coal-fired power plant located in Hong Kong, China, with a capacity of 4,108 MW. It is owned and operated by Castle Peak Power Company Limited (CAPCO), a joint venture between CLP Group and China Southern Power Grid. The plant plays a critical role in meeting the electricity demand of Hong Kong, a densely populated urban center. The facility operates under China's national emission standards and Hong Kong's local air quality regulations. As a coal-fired plant, it uses subcritical or supercritical technology typical of its era. The plant's large capacity places it among the top coal power stations globally, and its operations are subject to stringent environmental oversight due to its proximity to residential areas. Castle Peak power station is a key asset for Hong Kong's power grid, providing baseload electricity to millions of residents and businesses. Its environmental impact is managed through emission control systems, including flue-gas desulfurization and selective catalytic reduction, to reduce SOx, NOx, and particulate matter. The plant's significance extends to its role in supporting Hong Kong's economic activities while balancing environmental compliance.

The plant's coal fuel source results in significant CO2, SOx, and NOx emissions, contributing to local air quality concerns in the Pearl River Delta region. Its proximity to populated areas in Hong Kong necessitates advanced emission controls and compliance with stringent air quality standards. The facility's age and technology (likely subcritical or supercritical) influence its thermal efficiency and environmental footprint.
