An offshore wind farm CLP Power Hong Kong Limited has proposed would not have any adverse effect on the local ecosystem, Secretary for the Environment Edward Yau says.

In response to a question from legislator Regina Ip, Mr Yau told the Legislative Council that the proposed wind farm would be located approximately 9km east of the Clearwater Bay peninsula and 5km east of South Ninepin Island, more than 3km outside the boundary of the Geopark.

The environmental impact assessment of the wind farm CLP Power conducted points out that, given this location, and with mitigation measures in place, using the existing landforms as far as practicable to shield the wind farm turbines from view would reduce landscape and visual impacts.

CLP must get the Director of Environmental Protection's approval on the wind farm turbines' final layout. Its footprint should be minimised while the distance from the Ninepin and Ung Kong Groups must be maximised. 

Mr Yau said the report has recommended a type of foundation for the turbines that does not require piling, dredging or drilling into the seabed rock layer. Hence, it will not have an adverse impact on the seabed near the Ninepin Group nor on the area's natural environment.

As the selected site is far away from residential areas, its construction will not cause nuisance to the residents.

The report also notes that the wind farm's location is not in migratory birds' travelling path, and the sound frequency it would emit differs from the range most birds are capable of receiving.

Non-reflective paint will be applied to the mechanic parts of the turbines to reduce reflected sunlight that could .
