Hong Kong gets much of its power from mainland China, in particular about 70% of the output from Daya Bay’s 1888 MWe net nuclear capacity is sent there. A 2014 agreement increases this to 80%. The Hong Kong government plans to close down its coal-fired plants, and by 2020 to get 50% of its power from mainland nuclear (now 23%), 40% from gas locally (now 22%) and 3% from renewables. Another option, with less import dependence, is to increase domestic generation from gas to 60%, and maintain mainland nuclear at 20%.
Hong Kong utility China Light & Power (CLP) has equity in CGN’s Daya Bay (25%) power plant, and was until 2013 negotiating a possible 17% share in Yangjiang. After considering equity in a further CGN nuclear plant, in October 2016 CLP Holdings Ltd successfully bid for a 17% share in Yangjiang Nuclear Power Co Ltd, in response to a CGN general invitation to tender.
Since 1994 Hong Kong has been getting up to one-third of its power from Daya Bay output, and this contract now runs to 2034. According to CLP data, nuclear power cost HK 47 c/kWh in November 2013, compared with 27 cents for coal and 68 cents for gas, which provides the main opportunity to increase supply. CLP supplies about 80% of Hong Kong’s power.
