The Environment

On a temporary basis from 2014 to 2018, CLP Power is importing some additional 10 per cent of electricity generated by the Daya Bay station. The company is also drawing natural gas from the Mainland's Second West-East Natural Gas Pipeline through the Hong Kong Branch Line facilities.

CLP Power has the right to use up to half of the 1,200MW capacity of the Guangzhou Pumped Storage Power Station phase 1 at Conghua. It stores off-peak-period electricity from Castle Peak Power's stations and the Daya Bay station in the Conghua plant, 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 for domestic, commercial and industrial purposes. LPG is also used by nearly all taxis and more than 70 per cent of public light buses, while natural gas is used for electricity generation and production of town gas. Hong Kong has 1.86 million town gas and 430,000 LPG customers in the domestic, commercial and industrial sectors, of which town gas and LPG respectively accounted for 87.7 and 12.3 per cent of the total fuel gas sold in these sectors in terms of heating values in 2016.

Town gas is manufactured at plants in Tai Po and Ma Tau Kok, which have daily throughput capacities of 10 million and 2.6 million cubic metres respectively. It is channelled to customers via a 3,600km pipe network.

LPG is imported into Hong Kong mainly by sea and stored at five terminals on Tsing Yi Island before being distributed to customers, including 67 LPG filling stations for LPG vehicles.

Natural gas is imported from the Mainland via submarine pipelines to Castle Peak Power's stations and Lamma Power Station for electricity generation and to the Tai Po plant, and onward from Tai Po to the Ma Tau Kok plant via underground pipelines, for the production of town gas.

The Gas Safety Ordinance regulates the import, manufacture, storage, transport, supply and use of fuel gas. All gas supply companies, gas installers and contractors must be registered with the Gas Authority, who is 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. End users consumed a total of 289,160 terajoules in 2014, with the commercial, transport, residential and industrial sectors consuming 42, 31, 22 and 5 per cent respectively.

The Electrical and Mechanical Services Department's Energy Efficiency Office promotes efficient use of energy through initiatives including voluntary energy efficiency labelling and registration schemes, and encouraging the use of water-cooled air-conditioning systems and effective
