The Environment
about 70 per cent of the power generated by the Daya Bay station, which has two 984MW pressurised water reactors, to meet part of the longer-term demand for electricity in its supply area. The electricity sold to Guangdong is from CLP Power's existing reserve generating capacity. Its sale is governed by an agreement with the HKSAR Government, under which CLP Power's consumers get priority of supply and 80 per cent of the profit from the sales.
According to a memorandum of understanding signed between the HKSAR Government and the National Energy Administration on 28 August 2008, the Central People's Government supported the China Guangdong Nuclear Power Holding Company Limited in the renewal of its supply agreement with Hong Kong for a further 20 years. In September 2009, the government gave approval for CLP Power to extend the contract for the supply of nuclear electricity from the Daya Bay station for another 20 years from 7 May 2014 onwards. The quantity of electricity supply will be no less than the current level. On a temporary basis from October 2014 to 2018, CLP Power is importing some additional 10 per cent of electricity generated by the Daya Bay station. The company is also using natural gas supplies 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 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 Castle Peak Power system and the Daya Bay 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 for domestic, commercial and industrial purposes. LPG is also used as a fuel by nearly all taxis and more than 65 per cent of public light buses, while natural gas is used for electricity generation and production of town gas. Hong Kong has about 1.84 million town gas and 0.43 million LPG customers in the domestic, commercial and industrial sectors, of which town gas and LPG respectively accounted for 87.6 and 12.4 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 10 million and 2.6 million cubic metres respectively. A pipe network of some 3,500km 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 67 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.
