Ngawha Generation Limited (NGL) – a subsidiary of Top Energy – is expanding the capacity of its Ngawha Geothermal Power Station by a further 28 megawatts resulting in a total output of 53 megawatts by 2021.

Subject to a monitoring period to prove the sustainability of the geothermal resource, NGL’s resource consents provide for a second station to extend this capacity by a further 28 megawatts by no earlier than 2026.

The $176 million expansion project is one of the largest construction projects to be undertaken in the Far North and will improve the security and reliability of the power supply for the whole Northland region.

Once completed in 2021, the new power station will mean that Ngawha will export power south for 90% of the time, currently power is imported to the region from generation facilities in the Waikato.

The new power station will be called OEC4 and will be located off Ngawha Springs Road on land to the north of the existing power station and the Ngawha Springs settlement.

The land is a mixture of flat to moderate to steep gradient terrain and includes areas of pasture, wetland, scrub, native bush and forest.  Numerous watercourses feed into the Ngawha Stream.

There is an abandoned mercury mine site of archaeological interest and a geothermal gully area known as the Hidden Walks within the project site. These areas are not part of the project are not open to the public.
