Superhot geothermal is bigger bang for your buck, it is essentially unlimited. This isthe untapped renewable resource that enormous potential.

Drilling exploration

The Government has ring-fenced up to $60 million to invest in exploring the potential of superhot geothermal.

The Rotokawa geothermal field has been selected as the first well site because it benefits from decades of operational data, advanced geophysical imaging, and robust infrastructure, making it the ideal launchpad for supercritical exploration.

A Memorandum of Understanding to explore the potential of supercritical geothermal energy at the site has been signed between the landowners Tauhara North No.2 Trust, the Ministry of Business, Innovation and Employment, and Mercury NZ which operates the Rotokawa geothermal power station.

The project is being run by a top-tier New Zealand team of technical experts who will design the well, the equipment needs, and the steps to get us to the extreme depths for accessing supercritical geothermal fluids. Earth Sciences NZ is contributing technical and scientific expertise, which was funded by MBIE’s Endeavour Research Fund and years of other studies at the Taupō Volcanic Zone.

Meet our Exploration Partners

Earth Sciences New Zealand

Earth Sciences NZ contributes geological expertise to Next Generation projects, advancing subsurface modeling for supercritical geothermal targets in New Zealand. They support precise resource assessments, integrating seismic and reservoir data to reduce drilling risks in high-enthalpy fields. Their work fosters collaborative R&D, bridging academia and industry for sustainable geothermal expansion.

WING NZ

WING NZ champions diversity in geothermal via Women in Geothermal leadership, co-founding networks that amplify female expertise in Next Generation research. They facilitate inclusive engagement with Māori iwi and communities for equitable supercritical development. WING's advocacy ensures culturally responsive strategies, enhancing project outcomes and workforce participation in NZ's geothermal future.

Mercury

Mercury Energy NZ actively invests in geothermal reliability, partnering on Next Generation to explore supercritical potential for flexible, low-carbon power. They leverage existing assets like their Taupō fields to test advanced drilling and heat extraction techniques. This positions Mercury as a key enabler of NZ's transition to 24/7 renewables through innovative field optimization.

Jacobs

Jacobs brings global engineering prowess to geothermal initiatives, applying proven project management from large-scale plants like Kenya's Olkaria to NZ developments. In Next Generation efforts, they handle complex consenting, infrastructure design, and stakeholder engagement for supercritical pilots. Their focus ensures technical excellence while addressing cultural and environmental factors in geothermal builds.

Contact

Contact Energy is a leading player in New Zealand's geothermal sector, spearheading major developments like the Tauhara power station that boosts renewable output to power 200,000 homes. Through initiatives such as GeoFuture at Wairākei, they optimize geothermal fields for efficient, long-term electricity generation while minimizing environmental impacts on rivers like the Waikato. Their ongoing Te Mihi Stage 2 project further cements their commitment to expanding baseload renewables for national energy security.

Upflow

Upflow drives innovation in geothermal operations via the Geothermal: The Next Generation programme, leading Māori-engaged research for supercritical resource development. They developed GOOML, a machine-learning framework with partners like Contact Energy and NREL, boosting plant efficiency by 1-10% through digital twins. Upflow also translates subsurface data into commercial strategies, optimizing exploration and unlocking co-products like minerals from geothermal systems.
