The Electrical and Mechanical Services Department of EMSD has asked the Hongkong Electric Company, the power company that provides power to the affected areas, to identify the cause of the incident and submit a detailed report on it in four weeks, a government statement said.
The voltage dip happened in areas of Hong Kong Island at around 0:45am on Wednesday, the Fire Services Department said. Some areas were closed for about 40 minutes, with traffic lights malfunctioning and some people trapped inside lifts.
The FSD received 11 reports of people trapped in elevators in Causeway Bay, Wan Chai, Ap Lei Chau, North Point, and Sai Wan Ho between 1 am and 1:29 am, while many others reported automatic fire alarms setting off.
Over 10 shops inside the MTR s Hong Kong station went into darkness early on Wednesday due to a power failure. The MTR concourse had to operate without lighting and carry out transactions with cash following the outage.
The EMSD, which monitors the power companies to ensure a safe and reliable supply of electricity in the city, received a report on the incident from Hong Kong Electric Company at 1:27am that day.
The energy company has been closely following up with the power company on the development of the incident, and monitors the progress of repair work.
New subsidies on electricity charges, housing, will benefit millions.
The government conducts annually auditing review with the power companies with regard to technical, environmental and financial performance, a government spokesman said.
