Nga Awa Purua - Mighty River Power

Nga Awa Purua is a geothermal power station located near Taupo in New Zealand. The project was developed by Mighty River Power (now Mercury Energy).[1] Nga Awa Purua is New Zealand's second largest geothermal power station[2] and the steam turbine is the largest geothermal turbine in the world.[3]

The power station is a joint venture between Mercury Energy (75%) and the Tauhara North No 2 Trust (25%), who represent about 800 owners affiliated to Ngati Tahu.[4] The $430 million project first generated electricity on 18 January,[5] and was officially opened by Prime Minister John Key on 15 May 2010.[6]

The Rotokawa Power Station is situated close by.
