Castle Peak Power Station, located in the New Territories region, is a coal-fired power station. Two of its units can also burn gas as a backup fuel.

The station is owned by the Castle Peak Power Company Limited(CAPCO), a joint venture between CLP Power Hong Kong Limited (70%) and China Southern Power Grid International (HK) Co., Limited (30%), and is operated by CLP. It was built in the 1980s in response to the rapid growth of electricity demand in Hong Kong, and saw CLP shift its primary fuel from oil to coal, The use of coal has enabled us to provide reliable and affordable electricity to our customers. We recognise the community's desire for improved environmental standards. With the Emissions Control Project equipment fully operational since 2011, emissions from Castle Peak Power Station such as sulphur dioxide and nitrogen oxide have been significantly reduced.

The station additionally features a visitors’ centre called ElectriCity, which hosts informative displays on how electricity is generated and transmitted to peoples’ homes.
