Hongkong Electric (HKE) is studying the feasibility of developing a 100-megawatt (MW) offshore wind farm in Hong Kong waters, following its successful launch of the city’s first wind power project at Lamma Island earlier this year.
HKE submitted a project profile to Government for an environmental impact assessment (EIA) study brief to build the offshore wind farm at two potential sites: 3.5 km southwest of Lamma Island and 3.2 km southeast of Ninepin Group.
The sites were selected after taking into account factors such as wind potential, navigation channel, seabed utilities, marine conservation areas, water depths and proximity to Hongkong Electric’s power grid.
The project is undertaken in support of the Government’s policy of having 1-2% of electricity generated by renewable energy by 2012. As land resources are scarce in Hong Kong, the development of offshore wind farm is the only viable option.
Our plan is to build a total of 40 triple-bladed wind turbines, each of 2.5 MW, at the wind farm which can potentially generate about 175 million units of electricity every year. This is enough energy for about 50,000 families in Hong Kong, representing about 1.6% of Hongkong Electric’s electricity output in 2005—Dr. Tso Che-wah, HKE Chief Engineer (Projects)
The EIA study will take more than a year and is expected to complete by end 2007, covering areas like potential impacts on the environment, ecology and fisheries, both during construction and operation phases. At the same time, layout configuration design and cable routing will be studied, after which detailed wind monitoring will be carried out.
HKE projects that the wind farm will be ready for operation in 2012, based on the lead time required for the design, engineering, procurement, delivery and construction.
The project will supplant an estimated use of 62,000 tonnes of coal every year.

Earlier this year, HKE launched Lamma Winds, an 800kW pilot project at Lamma Island to gain practical experience in operating a wind turbine.
To commemorate the commissioning of Lamma Winds, the Hongkong Electric Company established the “Hong Kong Electric Clean Energy Fund” to encourage initiatives in promoting better understanding and application of renewable energy in Hong Kong. The fund will provide up to HK$1 million (US$129,000) in sponsorship for study and development of renewable energy technologies/applications in the local education sector.
