Bay, which has two 984MW pressurised water reactors, to meet part of the longer- term demand for electricity in its supply area.
According to the memorandum of understanding signed between the HKSAR Government and the National Energy Administration on August 28, 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 term of 20 years. In September 2009, the Government gave approval for CLP Power to extend the contract for the supply of nuclear electricity from Daya Bay Nuclear Power Station for another term of 20 years from May 7, 2014 onwards. The quantity of electricity supply will be no less than the current level.
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.
There are regulations under the Electricity Ordinance governing 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.
Climate
Hong Kong has a sub-tropical climate. About 80 per cent of its annual rainfall occur between May and September. August is the wettest month while January is the driest.
Tropical cyclones usually affect Hong Kong between June and October, often bringing high winds and widespread heavy rain. Landslips and flooding sometimes cause considerably more damage than the winds.
The Year's Weather
Both temperature and rainfall were near normal in 2010. Five tropical cyclones required the issuance of Tropical Cyclone Warning Signals, less than the average of six to seven a year.
