onwards. The quantity of electricity supply will be no less than the current level. In addition, in September 2013, commissioning of the Hong Kong Branch Line facilities was completed to support operations using the new natural gas supplies through Mainland China's Second West- East Natural Gas Pipeline.

CLP Power also has the right to use up to 50 per cent of the 1,200MW capacity of Phase 1 of the Guangzhou Pumped Storage Power Station at Conghua. Off-peak period electricity from the CAPCO system and the Guangdong Nuclear Power Station is stored in the pumped storage power station, which generates hydro-electricity to meet Hong Kong's demand during peak. periods.

Regulations under the Electricity Ordinance govern the registration of electrical contractors and workers and competent persons, safety of electrical wiring, supply of safe household electrical products and protection of electricity supply lines from third party damage.

Other Fuels

Town gas and liquefied petroleum gas (LPG) are the main types of fuel gas used in Hong Kong for domestic, commercial and industrial purposes. LPG is also used as a fuel by nearly all taxis and over 65 per cent of public light buses while natural gas is used for electricity generation and production of town gas. Hong Kong has about 1.8 million town gas and 0.46 million LPG customers respectively in the domestic, commercial and industrial sectors, of which town gas and LPG respectively accounted for 87.2 and 12.8 per cent of the total fuel gas sold in these sectors in terms of heating values.

Town gas is manufactured at plants in Tai Po and Ma Tau Kok which have daily throughput. capacities of 9.6 and 2.4 million cubic metres respectively. A pipe network of some 3,500 kilometres supplies town gas to customers.

LPG is imported into Hong Kong mainly by sea and stored at five terminals on Tsing Yi Island before being distributed to customers including 65 LPG filling stations for LPG vehicles.

Natural gas is imported from the Mainland via submarine pipelines to the Black Point, Castle Peak and Lamma Power Stations for electricity generation and to the Tai Po Plant for production of town gas.

The Gas Safety Ordinance regulates the importation, manufacture, storage, transport, supply and use of fuel gas. All gas supply companies, gas installers and contractors must be registered with the Gas Authority (the Director of Electrical and Mechanical Services).

Energy Saving

Energy Efficiency

Energy consumption is closely related to greenhouse gas emissions. Improving energy efficiency helps combat global climate change. The total energy consumption at end-use level in Hong Kong in 2012 was 287,970 TJ, with the commercial, transport, residential and industrial sectors consuming 42 per cent, 32 per cent, 21 per cent and 5 per cent respectively. The Electrical and Mechanical Services Department's Energy Efficiency Office runs a range of
