Nuclear power will play the largest role in decarbonising Hong Kong’s energy sector because of its reliability, according to the city’s major electricity provider.

CLP Holdings, which has a portfolio of power generation that includes nuclear, coal, gas and renewable sources, plans to import increasing amounts of clean electricity from mainland China to help Hong Kong meet its goal of making 60%-70% of its energy carbon-free by 2035, chief executive officer T.K. Chiang told Bloomberg Television.

Most of that will come from nuclear plants because nuclear generation is more reliable than intermittent generation from wind and solar farms, he said.
