context_page_description: Electricity sector in Hong Kong ranges from generation, transmission, distribution and sales of electricity covering Hong Kong. There are two main providers of electricity in Hong Kong.
context_section_description: HEC transmits electricity on Hong Kong Island at 275 kV and 132 kV voltage level to various load centres, in which the network consists mainly of underground and submarine cable.  The network is owned and operated by HEC. There are only few remaining 132 kV overhead lines in the system. The use of underground cable was chosen because it is ideal for a densely populated area like Hong Kong, and to ensure supply reliability even in bad weather, such as during typhoon.
  There are also six dedicated cable tunnels to accommodate some of the 275 kV fluid-filled cable circuits in Hong Kong Island and Lamma Island. In most of the load centres, the voltage is being stepped down to 22 kV or 11 kV for distribution purpose.
  CLP transmits electricity in Kowloon and New Territories at 400 kV and 132 kV voltage level. These transmission networks consist mainly of overhead lines. The network is owned and operated by CLP Power. In most of the load centres, the voltage is stepped down to 11 kV for distribution.
  Transmission networks of CLP Power and HEC are interconnected by three 132 kV submarine circuits from Hung Hom to North Point for emergency support but no economy power interchange is normally scheduled.
  CLP's 400 kV transmission network is also interconnected with the 500 kV China Southern Power Grid in Guangdong Province.
