Supply Reliability

Supply Reliability

HK Electric has been providing Hong Kong with one of the most reliable supplies of electricity in the world. The electricity supply rating of the Company has been maintained at higher than 99.999% since 1997 - a record that excels many top cities in the world.

To achieve and maintain such high reliability, appropriate provisions have been made in the design of the generation, transmission and distribution systems such that supply to customers can be maintained as much as possible even under contingency situations. The generation, transmission and distribution systems are closely monitored and controlled at our System Control Centre 24-hour a day. The Centre is equipped with advanced computer systems to ensure effective and efficient operation of the power system at all times.
