Our principal operating subsidiary, The Hongkong Electric Company, Limited (HK Electric), commenced operations in 1890 and is one of the longest-established utility companies in the world.
Over our long history, we have consistently supported Hong Kong's economic journey by offering safe, reliable and affordable electricity while minimising the impact of our operations on the environment as we strive to deliver sustainable growth in long-term value to our investors.
HK Electric Investments believes that open and on-going communication with our stakeholders is central to our operation and development. We engage different stakeholders through a variety of channels and stakeholder suggestions and feedback are highly valued in our decision making process as we strive for continuous improvements.
Underpinned by its core value of "Pursuit of Excellence", HK Electric is committed to delivering excellent services and supply reliability to our customers. We have been providing a world-class supply reliability of over 99.999% since 1997 and all our service standards are achieved or even surpassed every year.
As modern families aspire to an eco-friendly lifestyle, HK Electric promises its customers a green and comfortable way of life made possible by the use of electric appliances.
HK Electric is one of the longest-established power companies in the world. The Company has a world-class record of providing a highly reliable electricity supply to Hong Kong and Lamma islands at a reasonable and affordable price.
HK Electric has been the power behind Hong Kong for more than 120 years, having established a long and fruitful partnership with the community. While our prime mission is to provide a world-class electricity supply, we focus not only on the results, but also on the way we deliver them.
HK Electric aspires to be an employer of choice. We have policies and systems in place to attract talents and through continuous training and development, nurture them for a fulfilling career. We offer competitive remuneration, an ideal workplace and comprehensive wellness programmes for our employees while maintaining regular and open dialogues with them.
HK Electric is committed to protecting the environment of Hong Kong. We take great care in site selection and project planning while constructing our power station and have paid utmost attention in minimising its environmental impact. Whilst sparing no efforts to reduce the emissions, wastes and discharges from our operations, we are also looking for ways of recycling. For example, a significant percentage of our power station's solid wastes is recycled and used as raw materials in the construction industry. We have acquired a number of electric and hybrid vehicles to help improve roadside air quality. We are also a keen supporter of a wider application of renewable energy in Hong Kong, funding several pilot projects and feasibility studies on sustainable development.
Gas-fired Power Generation
Gas-fired electricity generation accounts for over 30% 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.
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 8.3 million kWh green electricity (as at end December 2018) has been produced, offsetting 7,000 tonnes of carbon dioxide emissions.
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 2018, Lamma Winds has generated more than 10.8 million kWh of green electricity, reducing over 3,700 tonnes of coal consumption and more than 9,000 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 2018 was about 123,000 cubic meters.
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.
