Tai Nam Wan (Chinese: 大南灣), or Nam Wan (南環, correctly 南灣), is a bay in the southern Tsing Yi Island, Hong Kong. The bay was reclaimed for Tsing Yi Power Station of China Light and Power.
Tai Nam Wan (大南灣) means Big South Bay. It is the a large bay at the south end of the island. As there is another south bay, Nam Wan (南灣), near Sai Tso Wan at island west, some refers this bigger one as big south bay. The Chinese name Nam Wan (南環) is mistakenly from Nam Wan (南灣). The two characters of Wan in Cantonese are of same pronunciation except the tone.
The bay is south of the highest peak among Tsing Yi Peak on the island,between Nam Wan Kok and Ng Tsang Lau and faces the west water of famous Victoria Harbour. The water is anchorage of cargo vessels from all around the world.
The bay was completely reclaimed for Tsing Yi Power Station and the shore line is straightened. The power station was built in 1960s and currently demolished. A smaller station Tsing Yi Gas Turbine Power Station was established instead. An Esso Oil Depot occupies part of the reclamation.
