Guangzhou Pumped Storage Power Station has a total capacity of 1,200MW and was developed in two stages (1993-1994 & 1999-2000). Hong Kong Pumped Storage Development Company, Limited (PSDC) is wholly-owned by CLP, which has the contractual rights to use the equivalent of half of the first stage of the project (600MW) for 40 years until 2034.

CLP participated in the development of the first stage of the pumped storage power station through PSDC. We use the contracted pumped storage capacity to support the operation and security of the Hong Kong electricity supply system.
