Promoting the Use of Renewable Energy in Hong Kong

The Government as well as some other non-government organizations have been promoting the use of renewable energy in Hong Kong through conducting studies and publicizing results of the studies, public education, demonstration projects, etc. Among these, this website is one of the promotional initiatives of the Government.

In year 2000, the Energy Efficiency Office commissioned a two-stage consultancy study to investigate the viability of using renewable energy resources such as solar energy, wind energy, wave energy, landfill gas, etc. in Hong Kong. Stage 1 of the study, completed in December 2002, evaluated the potentials of various forms of renewable energy for wide-scale local use, and their related legal, institutional and promotional issues. It also made recommendations for formulating an implementation strategy. Stage 2 of the study involved the installation of different types of photovoltaic panels in Wanchai Tower so as to collect technical data to assess their performance under local weather and environmental conditions. The twelve-month performance monitoring work was completed in March 2004.

The reports of the whole study can be dowloaded here:

In 2005, the Energy Efficiency Office published the "Technical Guidelines on Grid Connection of Small-scale Renewable Energy Power Systems". The Technical Guidelines provides information on the safety aspect, equipment protection aspect, reliability aspect, and power quality aspect of small-scale renewable energy systems. In 2007, a revised edition of the technical guidelines, titled "This web page has hyperlinks which may transfer you to third-party website.Technical Guidelines on Grid Connection of Renewable Energy Power Systems (2007 Edition)" was made available to the public, which extends the applicable capacity limit of the original guidelines from 200kW to 1MW.

In 2005, the Electrical and Mechanical Services Department put into service a 350kW PV installation in Hong Kong and a 1kW small wind turbine on the roof of the EMSD Headquarters building. The installation becomes part of the EMSD Education Path at the EMSD Headquarters, which is open for visit by interested organizations.

In the period 2004-2006, the Energy Efficiency Office implemented a Wind Measurement Programme to gather wind data on the eastern part of Hong Kong. Upon the conclusion of the programme in 2006, the gathered data were used to produce a more detailed wind resource map for Hong Kong, which is now available on this website under the Wind Resource Maps section.

In 2004, the Council of Sustainable Development launched a public engagement process to collect the public and the stakeholders' views on various topical issues including the development of renewable energy in Hong Kong. Based upon the results of the public engagement process, the This web page has hyperlinks which may transfer you to third-party website.First Sustainable Development Strategy for Hong Kong was formulated in May 2005, covering the areas of Solid Waste Management, Renewable Energy, and Urban Living Space. In the Strategy, specific targets were drawn up for the area of Renewable Energy. Information about the targets can be found under the RE Target for HK section of this website.

The first commercial-scale wind turbine in Hong Kong was built by the Hongkong Electric Company (HEC) limited as a demonstration project on Lamma Island. The wind power station, which consists of a single wind trubine and a cluster of exhibition panels, was inaugurated in February 2006. The wind turbine is an 800 kW a three-blade machine with a rotor diameter of 50 meters. The hub height of the wind turbine is 46 metres. The wind turbine generates electricity when the wind speed falls in the range of 3 m/s to 25 m/s.

The other power company in Hong Kong, CLP Power (Hong Kong) Limited, is planning to construct a commercial-scale wind turbine on an island in Hong Kong, also to serve as a demonstration project.

Besides, both power companies are also exploring the feasibility of constructing off-shore windfarms in Hong Kong waters (see Offshore Wind Farm - Technology Outline section). Furthermore, both power companies have set up funding schemes to provide support to community projects on renewable energy and energy efficiency (see Sponshorship section).

Universities in Hong Kong have been actively conducting research studies in the application of renewable energy. The Centre for Renewable Energy (CORE) of the University of Hong Kong (HKU) and the Renewable Energy Research Group (RERG) in the Hong Kong Polytechnic University (PolyU) are research groups studying the applications of renewable energy in Hong Kong. CORE focuses on building-integarted photovoltaic and the grid connection issues of photovoltaic systems. RERG focuses on the applications of solar and wind energy. Research on the production of biodiesel from recycled oil and its application in Hong Kong has been undertaken by HKU. The Division of Building Science and Technology in the City University of Hong Kong (CityU) is conducting research on the solar and wind energy and their applications in buildings.

Non-government organizations are working more on the education and advocacy of renewable energy in the community. Friends of the Earth (Hong Kong) and Green Peace (China) are active in promoting the application of renewable energy. Other green groups have also undertaken initiatives to educate the community on renewable energy.

The Hong Kong PV Consortium (HKPVC) is an organization formed by members from the academic and the business sectors to promote the application of photovoltaic technology in Hong Kong, through training programmes and seminars.
