Electrical and Mechanical Services Department requests CLP Power Hong Kong Limited to submit report on power supply incident in some areas of Kowloon and New Territories

******************************************************************************************

     There was a power supply incident in some areas in Kowloon and the New Territories at around 1.29pm today (April 6). In accordance with the established mechanism, the Electrical and Mechanical Services Department (EMSD) received the notification on the incident from CLP Power Hong Kong Limited (CLP) at around 2.01pm. According to CLP's notification, there was a brief voltage dip recorded in CLP's 400kV power supply system in Tuen Mun, during which there was no interruption to the power supply. Since the voltage dip occurred in a high voltage system, a brief voltage dip was resulted from the incident. Nearby electricity customers may experience dimming or flickering in lighting system; some electrical installations sensitive to voltage changes, such as lifts, may suspend operations due to the activation of protection system. According to information provided by CLP, the brief voltage dip was preliminarily suspected to be related to an equipment fault in Black Point Power Station.

     The Government is very concerned about the several recent voltage dip incidents. The Environment and Ecology Bureau has requested CLP to provide an explanation to the public and take effective measures to make improvement and has instructed the EMSD to step up monitoring CLP's technical and electrical safety performance.

     Subsequent to CLP's notification, the EMSD has immediately followed up with CLP on the development of the incident, and deployed staff to the scene to conduct assessment. The EMSD has requested CLP to identify the cause of the incident as soon as possible and submit a detailed report on the incident within four weeks.

     Moreover, the EMSD has requested the registered lift contractors to report the situation of the affected lifts, as well as to send staff to affected areas to help release the trapped lift passengers and reset the operation of the lifts. The EMSD will continue to maintain close contact with CLP, and urge CLP to conduct appropriate follow-up work.
