New Zealand’s geothermal development relies on an assessed geothermal-power resource potential, which is 4 GWe (or 30 TWh/yr) from conventional convecting geothermal systems. These systems are hosted at depths of up to 4 km, mostly within the Taupo Volcanic Zone (TVZ). The deeper, hotter, and yet to be explored roots (3.5 – 6km) of this zone have been provisionally assessed by Bromley et al (2024) at ~3.5 GWe of additional potential.
The operational geothermal capacity as of the end of 2023 was 1055 MW, with annual generation of ~8000 GWh. Annual direct use amounted to some 10 PJ, although it is noted that high accuracy direct use data is lacking.
