Powerco is the second-largest gas and largest electricity distributor in New Zealand. It is one of only two companies to distribute both electricity and natural gas through their network (the other being Vector Limited). Its network delivers electricity and gas to households around the North Island from the national electricity distribution network Transpower and the natural gas transmission system owned and operated by Vector Limited. Powerco arose from the energy reforms in New Zealand in the 1990s. It can trace its history back to a number of local power boards and gas companies that operated throughout the North Island. The company is 58% owned by QIC Limited - an investment firm owned by the Queensland Government - and 42% owned by AMP Limited.〔(【引用サイトリンク】 title=Our People )〕 ==Business== The New Zealand electricity reforms of the 1980s split the electricity industry broadly into four sections - generators, transmitters, distributors and retailers. Six main generator businesses (Meridian Energy, Genesis Energy, Contact Energy, Mighty River Power, Trustpower and Todd Energy) generate electricity and supply it to New Zealand's national grid, operated by Transpower. Transpower transmits high-voltage electricity to grid exit points (or substations) around New Zealand for transmission to households and businesses. The local distribution network (mostly consisting of underground wires and/or overhead wires) that transmit electricity to end-users like households and businesses are owned and operated by local distribution companies, mostly regionally based.〔(【引用サイトリンク】 title=Our Business: New Zealand's Electricity Market )〕 Powerco is a distributor whose business is completely separate from generation, national transmission and retail (selling delivered electricity to end-users). It operates a 30,000 km local electricity distribution network supplying 320,000 households, industries and businesses from Transpower's national grid and a 6,000 km natural gas distribution network supplying 102,000 households, industries and businesses from Vector's transmission system. Its electricity network currently supplies the following regions: * Taranaki * Manawatu-Wanganui * Rangitikei * Wairarapa * Tauranga (and surrounding rural areas) * Eastern and southern Waikato * Thames-Coromandel District Powerco's natural gas distribution network covers: * Taranaki * Manawatu * Palmerston North * Horowhenua District *Hawke's Bay Region * Hutt Valley * Porirua * Wellington City〔(【引用サイトリンク】 title=Our Business: Our Networks )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Powerco」の詳細全文を読む スポンサード リンク
