In Hong Kong, CLP operates a vertically integrated electricity supply business encompassing power generation, transmission, distribution, and retail services, providing reliable and continuous electricity supply to more than 80% of the city’s population. Through Castle Peak Power Company Limited (CAPCO), a joint venture with China Southern Power Grid International (Hong Kong) Company Limited, CLP operates the Castle Peak Power Station, Black Point Power Station, Penny’s Bay Power Station, as well as the landfill gas-to-energy project “CLP Green Power” located at the West New Territories Landfill.
As at 30 June 2025, CLP’s total installed generation capacity in Hong Kong amounted to 7,222 megawatts. CLP also imports electricity into Hong Kong from the Daya Bay Nuclear Power Station in Guangdong Province. In addition, CLP operates an extensive transmission and distribution network comprising more than 17,300 kilometers of power lines and over 16,000 substations, providing world-class electricity infrastructure to support Hong Kong’s development.
CLP’s operations in Hong Kong are governed by the Scheme of Control Agreement, which provides a regulatory framework to monitor operational performance and defines the levels of investment and permitted returns. Over the years, the Scheme of Control has proven effective in ensuring that CLP delivers electricity services to Hong Kong at world-class levels of reliability, with reasonable pricing and strong environmental performance.
CLP shares the community’s commitment to environmental protection and began transitioning to cleaner fuels many years ago. Despite electricity demand in Hong Kong increasing by nearly 90% since 1990, CLP has reduced its emissions by more than 90% over the same period, demonstrating its long-standing commitment to emissions reduction and energy transition.
In addition, CLP’s energy infrastructure and solutions subsidiary, CLP China Energy, provides an expanding portfolio of sustainable energy technologies and solutions to support customers in their decarbonization efforts. These offerings include district and building cooling systems, solar energy solutions, electric vehicle charging infrastructure, battery energy storage systems, and liquefied natural gas (LNG) refueling services.
