     During the meeting, the EMSD requested CLP to immediately strengthen inspections on the power supply system in the concerned district, targeting to complete this month, and review maintenance arrangements of the territory-wide transmission and distribution system to prevent recurrence of similar incidents. In accordance with the Electricity Ordinance (Cap. 406), the EMSD monitors the operation of the power companies to ensure a safe and reliable supply of electricity in Hong Kong. The EMSD has instructed CLP to submit detailed reports on the incidents as soon as possible, and will continue to closely follow up with CLP and monitor CLP's appropriate follow-up and improvement measures.
