Ohaaki Geothermal Power Station

The Ohaaki Power Station is a geothermal power station owned and operated by Contact Energy.

Although initially constructed to generate 104 MW, decline in the steamfield has meant that the maximum net capacity is about 65 MW.

A distinctive feature of this power station is the 105 m high natural-draft cooling tower, the only one of its kind in New Zealand.

The plant is located adjacent to the Ohaaki Marae on the banks of the Waikato River. The area of the marae is sinking approximately 170mm a year. This has been attributed to draw-off of geothermal fluids by the power station.
