To satisfy the aspirations from the community, and in support of Government’s energy and environmental policy objectives, HK Electric has launched a suite of "Smart Power Services".
HK Electric is one of the longest-established power companies in the world. The Company has a world-class record of providing a highly reliable electricity supply to Hong Kong and Lamma islands at a reasonable and affordable price.
HK Electric Investments is committed to meeting the long-term energy needs and supporting the sustainable development of the community we serve. To do this, we focus not only on powering Hong Kong with a world-class electricity supply, but also on the way we deliver it and the impacts it has on the environment.

We offer competitive remuneration, an ideal workplace and comprehensive wellness programmes for our employees while maintaining regular and open dialogues with them.
HK Electric supplies electricity to Hong Kong Island and Lamma Island. Electricity is first generated at Lamma Power Station and transmitted at very high voltage - 275kV and 132kV to the load centres where it is stepped down in the primary substations to 22kV or 11kV. It is then distributed to customers through the 22kV and 11kV distribution networks to the secondary substations where electricity is further transformed to 380V/220V for customer's utilization.
HK Electric provides with its customers one of the most reliable supply of electricity in the world. We are proud of our record that the electricity supply reliability rating of the Company has been maintained at 99.999% every year since 1997. In order to achieve high reliability, appropriate provisions have been made in the design and operation of the generation, transmission and distribution systems to cope with contingency and to maintain stable electricity supply. The generation, transmission and distribution systems are continuously supervised and controlled remotely at its System Control Centre, which is equipped with state-of-the-art system computers to ensure effective and efficient operation of the power system at anytime.
Although the electricity supply of HK Electric is one of the most reliable in the world, being a public supply system, it is susceptible to external influences, for instance, damage of the underground cable by road excavation, customer installation fault or fault in the interconnected system outside Hong Kong Island. Electrical fault in the transmission and distribution system may also occasionally occur. Therefore, we highly recommend customers to provide back up supply for important services, such as emergency generator and/or uninterruptible power supply, to minimize inconvenience to their business caused by supply interruption and voltage dip.
Voltage dip may occur due to lightning or a fault in the power system. These voltage dips are just of very short duration. Most equipment will be able to "ride over" and operate as usual, but some sensitive equipment, such as computer equipment, will need to have uninterruptible power supply to maintain continuous operation. However, as HK Electric uses underground cable extensively for transmission, voltage dips induced by lightning are far less frequent than other countries/cities which have substantial overhead line installation in the power system.
HK Electric has installed power quality monitoring equipment at strategic locations in the power system. The data are used to trend the power quality of the power system and formulate long term power quality strategy of the Company. In order to maintain power quality and avoid undue interferences onto the power system caused by customer installations, the Company has specified certain technical requirements relating to voltage fluctuation and harmonic distortion that customers must comply with, in order to limit the magnitude of the effect on other customers.
Electricity will be supplied using the Alternating Current (A.C.) system at a frequency of 50 Hertz. The following voltages are available at the discretion of the Company:
(a) Single phase: 220 volts(b) Three phase:
The declared limits of the supply under normal conditions are:
(b) Frequency: 50 Hertz (plus or minus 2%)
