Gas-fired Power Generation Gas-fired electricity generation accounts for over 50% of our total power production. It is environmentally friendly, as it emits minimal quantities of sulphur dioxide and particulates, while nitrogen oxide and carbon dioxide emissions are greatly reduced. |
Solar Power HK Electric has built one of the Hong Kong's largest commercial-scale solar power systems, which is also the first large scale project applying the amorphous silicon thin film photovoltaic panels in the territory. Since its inception in July 2010, more than 11.7 million kWh green electricity (as at end December 2021) has been produced, offsetting 9,700 tonnes of carbon dioxide emissions. |
Wind Power Hong Kong's first commercial-scale wind power station, Lamma Winds - a pioneer in the use of renewable energy in the territory - was commissioned on 23 February 2006. By the end of December 2021, Lamma Winds has generated more than 13.2 million kWh of green electricity, reducing over 4,500 tonnes of coal consumption and more than 11,000 tonnes of carbon dioxide emissions. |
Flue Gas Desulphurisation Plant Flue Gas Desulphurisation Plant is installed to remove over 90% of sulphur dioxide in the flue gas. All of the Lamma coal-fired units currently in operation are equipped with FGD systems. |
Low NOx Burners With the use of low NOx burners, concentration of NOx in the flue gas is reduced by two-third comparing with that produced by a conventional unit. A total of five Lamma coal-fired units responsible for 88% coal-fired generating capacity are now equipped with LNB systems. |
Electrostatic Precipitators and Chimneys Electrostatic Precipitators remove over 99% of particulates in the flue gas. The tall chimneys effectively disperse the pollutants to very low concentrations when they reach ground level. |
Air Quality Monitoring Station HK Electric has installed a total of six air quality monitoring stations in the south of Hong Kong Island and in Cheung Chau to monitor the impact of Lamma Power Station on the ambient air quality. Results obtained are considered well within the Hong Kong Air Quality Objectives. Please browse the following for the monitoring data: |
Noise Monitoring Station HK Electric has installed a total of six monitoring stations at strategic locations both inside and around the Lamma Power Station to continuously monitor the noise impact on the nearby villages. |
Rain and Effluent Rainwater and run-off water from the coal pile is collected and used in the computerised water spraying system for the coal yard, significantly reducing both the consumption of fresh water and the quantity of effluent. The rainwater and waste water collected for reuse in 2021 was about 113,000 cubic meters. |
Seawater Monitoring Scuba divers and laboratory technicians take biological, seabed sediment and water samples from the coastline around the power station on a regular basis, and laboratory tests and analysis of these samples confirm that marine life has not been affected by the power station's operations. |
Submerged Scraper Conveyors Submerged scraper conveyors handle furnace bottom ash from all coal-fired units, drastically reducing the quantity of wastewater discharged from the power station. |
Foam Suppression Water-Spraying System The large quantity of cooling water discharge can generate foam which is environmentally harmless but may be unsightly, so a foam suppression system comprising a retaining wall and water spray has been built to enclose and disintegrate the foam at the cooling water outfall. |
Effective By-product Management Ash is the major solid by-product of burning coal. Coal ash can be used for landfill purposes or for making cement and brick, and is marketed to contractors as a construction material for the building industry. An ash lagoon is in place to provide a temporary storage space for ash. Gypsum is a solid by-product from the FGD systems and we promote its beneficial use in industry. |
