Lamma Extension Gas: 335 MW Gas Power Plant on Lamma Island, Hong Kong

Lamma Extension Gas is a gas-fired power plant situated on Lamma Island, Hong Kong, China. With a capacity of 335 MW, it represents a medium-scale facility within the country's extensive power generation sector. The plant is operational and contributes to the electricity supply for Hong Kong, a densely populated urban center. The facility utilizes natural gas as its primary fuel, which typically results in lower emissions of sulfur dioxide (SO2) and particulate matter compared to coal-fired plants. In China, gas-fired power plants are subject to national emission standards under the Air Pollution Prevention and Control Law, as well as local regulations in Hong Kong. The technology employed is likely combined cycle gas turbine (CCGT), which offers higher efficiency and lower carbon intensity than older subcritical units. Lamma Extension Gas plays a key role in supporting Hong Kong's energy needs, particularly as the region transitions toward cleaner energy sources. Its location on Lamma Island, away from the main urban areas, helps mitigate local air quality impacts. The plant's operation aligns with broader efforts in China to increase the share of natural gas in the energy mix, reducing reliance on coal and lowering greenhouse gas emissions.

The plant's use of natural gas results in lower CO2 emissions per MWh compared to coal, but still contributes to greenhouse gas emissions. Its location on Lamma Island, near Hong Kong's populated areas, requires careful management of NOx and other pollutants to comply with local air quality standards. The facility's capacity of 335 MW places it in the medium-scale range for gas plants, and its operational status suggests ongoing regulatory oversight under China's environmental laws.
