Electricity industry overview
- Electricity in Hong Kong is provided by two privately owned companies, CLP Power Hong Kong Limited (CLP) and The Hongkong Electric Company Limited (HKE).
- CLP supplies electricity to Kowloon and the New Territories. Electricity is generated by three power stations: Castle Peak (4108 MW), Black Point (3175 MW) and Penny’s Bay (300 MW), with a total installed capacity of 7583 MW. CLP has also contracted to purchase about 70% (on a temporary basis until 2023) of the power generated from the two 984 MW pressurised water reactors in the Guangdong Daya Bay Nuclear Power station. It also has the right to use 50% of the 1200 MW capacity of Phase 1 of the Guangzhou Pumped Storage Power Station at Conghua.
- HKE supplies electricity to Hong Kong Island, Ap Lei Chau and Lamma Island. Electricity is generated by the Lamma Power Station, which has a total installed capacity of 3637 MW at the end of 2020.
- Between 2009 to 2020, electricity generation in Hong Kong has remained around the level of 35 to 40 TWh per year. The volume of electricity imported since 2008 has increased, while the volume of coal imported has decreased. This is due to the fact that Hong Kong is cutting down reliance on fossil fuels.
Electricity laws
- The regulation of the electricity market is exercised through the Scheme of Control Agreements entered into between the Government of Hong Kong and CLP and HKE, respectively. The Scheme of Control Agreements sets out, among other things, the rights and obligations of the power companies, the electricity-related financial affairs of the power companies as well as their reliability and environmental performance in providing electricity. The current Scheme of Control Agreements will expire on 31 December 2033.
- The Electricity Ordinance (Cap. 406) regulates the safe supply of electricity and the safety of household electrical products. Among other things, it covers the registration of generating facilities, contractors and workers for electrical installations, wiring installation standards and safe distribution and use of electricity.
- The Electrical Products (Safety) Regulation was enacted in 1997 and its main provisions, including specified safety requirements for household electrical products, came into effect in May 1998. The remaining provisions concerning certificates of safety compliance requirements commenced operation in December 2000.
- The Electricity Supply Lines (Protection) Regulation was enacted in April 2000 to deter damage to underground electricity cables and overhead electricity lines. It commenced operation on 1 April 2001.

Renewable energy overview
- Based on commercially available technologies, it is estimated that Hong Kong has a renewable energy potential of about 3-4% of total electricity consumption arising from wind, solar and waste-to-energy that can be exploited between now and 2030. In 2018, the amount of electricity generated from renewable energy accounted for less than 1% of power consumption in Hong Kong.
Solar
- Currently, the largest solar energy generation system in Hong Kong has been installed at the Hong Kong Disneyland Resort, which has a capacity of 2,100 KW and is comprised over 5000 monocrystalline solar panels on the rooftops of 20 buildings.
- The current cumulative photovoltaic (PV) installation capacity in Hong Kong is less than 5 MW. There are over 200 relatively small projects in Hong Kong, where PV panels and solar water heaters have been installed mainly at schools and on the rooftops of public sector buildings and facilities as a result of the Hong Kong Government taking the lead to encourage the use of solar energy to generate electricity.
Wind
- Since 2000, the Hong Kong Observatory began to use wind power as an energy source in some remote automatic weather stations which have been relying on solar power. As sunshine in cloudy days may not be sufficient to keep the operation of those weather stations, wind turbine generators have been employed to provide an alternative energy source.
- The first commercial-scale wind power station was completed in February 2006 on Lamma Island, operated by HKE. The rotor diameter is 50 meters with a rated output power of 800 KW.
- Studies show that Hong Kong has two potential sites for developing wind power on a commercial scale, one at South West Lamma with the potential to develop a 100 MW capacity wind farm producing 175 GWh of electricity annually and another at South East Ninepin with potential to develop a 200 MW wind farm.
Solar & wind
- The first wind/solar hybrid system in Hong Kong was installed at the Shek Kwu Chau Drug Rehabilitation Centre. The first commercial-scale combined PV and wind turbine renewable energy power station at 200 kW capacity on Town Island was completed in 2011.
Waste-to-energy
Landfill
- There are three strategic landfills in Hong Kong, namely West New Territories Landfill, South East New Territories Landfill and North East New Territories, which have been utilizing landfill gas for energy production. The current uses include generating electricity for use in on-site infrastructures.
- The surplus landfill gas generated from North East New Territories Landfill is treated and delivered to Hong Kong & China Gas' (HKCG) production plant in Tai Po for use as alternative energy source.
- The surplus landfill gas generated from South East New Territories Landfill is treated (in the form of synthetic natural gas) and conveyed to HKCG's Offtake Station at Tseng Lan Shue, where the treated gas is blended with town gas for injection to the supply grid for HKCG's customers.
- Apart from the strategic landfills mentioned above, there are 13 closed landfills. The landfill gas generated from some of the larger closed landfills, namely Shuen Wan, Gin Drinkers Bay, Jordan Valley, Tseung Kwan O Stage I, II and III and Pillar Point Valley landfills, has been used as an energy source.
- For Shuen Wan Landfill, a special arrangement has been made with HKCG for piping the landfill gas to their plant for utilization. Landfill gas is also used as fuel in electricity generation to meet on-site uses in Jordan Valley and Tseung Kwan O Stage I landfills. For Gin Drinkers Bay, Tseung Kwan O Stage II/III and Pillar Point Valley, the landfill gas is used as a thermal energy source in the treatment of landfill leachate.
Biogas
- Hong Kong has been utilizing biogas from digesters in the sewage treatment works in Sha Tin, Tai Po, Fan Ling, Yuen Long for a number of purposes – in boilers for producing hot water for the digesters, in engine-driven blowers to provide compressed air for the sewage treatment process, and in engine-driven electric generators to provide electricity for the sewage treatment works.
- An example is the 330 KW engine-driven combined heat and power generator at Shek Wu Hui Sewage Treatment Works, which was commissioned in 2006 and subsequently connected to CLP’s distribution network in 2008. The electricity generated is supplied to existing E&M facilities while the recovered thermal energy is used for pre-heating the recirculation water for maintaining the required temperature for the sludge digestion process in the sewage treatment works.
Hong Kong
- Hong Kong has neither indigenous fuel sources nor the physical conditions favorable for large-scale development of renewable energy as it only has a land area of 1,106 square kilometers, much of which is hilly terrain.
- Although the technologies for renewable energy has advanced, there is concern about the cost of renewable energy being generally higher than that of conventional energy. For instance, studies show that it may take over HK$10 billion to build the two potential wind farms mentioned above but the electricity generated could only provide for less than 1.5% of Hong Kong’s total electricity consumption.
- It will depend on whether technology for renewable energy storage may allow large quantities of renewable energy to be stored in order for renewable energy to become a reliable source of energy production in Hong Kong.

Hong Kong
There are generally no restrictions on foreign investment in Hong Kong. It does not distinguish in law or practice between investments by foreign-controlled companies and those controlled by local interests. Foreign firms and individuals can incorporate their operations in Hong Kong, register branches of foreign operations, and set up representative offices. There is no restriction on the ownership of such operations. Company directors are not required to be citizens of, or resident in, Hong Kong. Reporting requirements are straightforward and not onerous.
Hong Kong
- The Paris Agreement applies to Hong Kong.
- In January 2017, Hong Kong released the Climate Action Plan 2030+ which outlines its targets, including reducing its carbon intensity by 65% to 70% by 2030 using 2005 as a base.
- Hong Kong will review its climate change efforts every 5 years since 2019 and align them with the submission timelines under the Paris Agreement.
- The carbon reduction plan includes phasing down coal for electricity generation and replacing it with natural gas by 2030.
