Ngāwhā Geothermal Power Station
Top Energy owns and operates the Ngāwhā Geothermal Power Station on the Ngawha geothermal field. It utilises binary cycle technology manufactured by Ormat Industries and produces 56MW.

The power station opened in 1998 with a generating capacity of about 8 MW. It was the first power station to come into operation via a resource consent applied for and issued under the Resource Management Act 1991. In 2008, the plant was expanded, increasing the capacity to 25 MW and allowing the power station to provide 70% of Northland's electricity. 

In 2015, consents were granted for expansion with a further 50 MW of generation in two stages at a nearby site, with work beginning in late 2017. The first stage of the second expansion, generating an additional 32 MW was officially opened in July 2021. The stations now generate all the electricity the Far North needs for 97 per cent of the time, with surplus power sent to the national grid.
