Lamma Winds began operating on 23 February 2006, and was the first commercial-scale wind turbine in Hong Kong. The wind turbine is a Nordex N50/800 kW model with a rotor diameter of 50 metres (160 ft), a nameplate capacity of 800 kilowatts (1,100 hp) and a capacity factor of about 13% which delivers an average output of around 100 kilowatts (130 hp). It can generate enough power for approximately 250 households in ideal conditions, though typically considerably fewer. Before the construction of the wind turbine, Environmental Resources Management of Hong Kong analyzed its environmental impacts, and predicted no significant adverse effects.
Lamma Winds is one of the relatively few commercial-scale wind turbines in the world that is open to the public. An exhibition centre surrounds the base of the wind turbine, and is open daily from 7 AM to 6 PM, including weekends and holidays. Access to the exhibition center is by foot; the walk from Yung Shue Wan Ferry Pier takes about 40 minutes.
