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 downloaded 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.

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 turbine 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). 

During the Public Consultation on the Future Development of the Electricity Market in 2015, public attitude towards the development of Renewable Energy (RE) was positive. There was general support for the further development of RE, despite its higher tariff implications.
Under the post-2018 Scheme of Control Agreements (SCAs), Feed-in Tariff (FiT) and RE Certificates are two important new initiatives to promote the development of distributed RE. FiT will help encourage the private sector to consider investing in RE as the power generated could be sold to the power companies at a rate higher than the normal electricity tariff rate to help recover the costs of investment in the RE systems and generation. At the same time, RE Certificates will be sold by the power companies for units of electricity from RE sources. Through these RE Certificates, the community can show its support for RE. The revenue from the RE Certificates will also help alleviate the overall tariff impact on all consumers brought about by the introduction of the FiT scheme. Apart from the FiT and RE Certificates schemes, the power companies will facilitate grid connection and improve the relevant arrangements.
