Ngatamariki is a geothermal power station commissioned in 2013 and operated by Mighty River Power. It is located approximately 17 km north east of Taupo and was constructed well under the budget of $475 million. The field was initially explored by the Crown in 1985-86, with the wells NM1, NM2, NM3, and NM4 drilled to 1300m, 2403m, 2194m, and 2749m respectively. NM4 was the first well in New Zealand to encounter a pluton, at a depth of almost 2400m. Mighty River undertook further drilling in 2008-09, with wells NM5, NM6, and NM7 drilled to depths of 2997m, 3398m, 2963m respectively. Resource consents for further development were granted in May 2010. Work at the geothermal field site on the first stage of the plant (82 MW) commenced in July 2011 and the plant became operational in September, 2013, one month later than scheduled.〔 The power station is a binary plant, supplied under an EPC contract by Ormat. A 220,000-volt power line connects Ngatamariki to Mighty River Power's Nga Awa Purua Power Station, where electricity from both stations is injected into Transpower's national grid. The Ngatamariki Geothermal site consists of 7 geothermal wells (3 production and 4 re-injection). In addition to the main goethermal wells, there are 21 sentinel and monitoring wells, to depths of 1,500m.〔 == See also == * List of power stations in New Zealand 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「Ngatamariki Power Station」の詳細全文を読む スポンサード リンク
