The plant is powered with steam and fluid from the Tauhara steamfield, and all used geothermal fluid is reinjected back into the edge of the steamfield.

The general flow of fluids (water, hydrocarbons, geothermal fluids, etc.) in deeper formations is also a concern of geologists, geophysicists and petroleum geologists.

The thermal efficiency of geothermal electric plants is low, around 10-23%, because geothermal fluids are at a low temperature compared with steam from boilers.

The modern practice of injecting geothermal fluids back into the Earth to stimulate production has the side benefit of reducing this environmental risk.

Geothermal Electric Power Wells - Class V wells that dispose of spent geothermal fluids following the extraction of heat for the production of electricity.

The geothermal fluid is supplied from a total of 4 production wells, GK-1, GK-3, GK-7 and GK-9.

Its focus is on exploring existing reservoirs containing hot geothermal fluids.

Gradual sinking of the marae has been attributed to draw-off of geothermal fluids by the power station.

Other mineral occurrences of potential economic interest included diatomite, geothermal fluids and mineral salts, gold, gypsum, perlite, petroleum, and pumice.
