The project was developed by Mighty River Power (now Mercury Energy). Nga Awa Purua is New Zealand's second largest geothermal power station and the steam turbine is the largest geothermal turbine in the world.
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.
