Abstract
Aquifer permeability within the Mangakino geothermal system is possibly controlled by reactivation and reopening of old fractures at the intersection of NE-SW trending fault and NW-SE trending fault. The most reliable reservoir temperatures range from 265 °C to 291 °C. The total stored heat in the system is estimated to be between 887 PJ and 2229 PJ. The potential power capacity that can be developed in the system is between 10 and 26 MWe. Geothermal energy could benefit nearby timber operations in terms of: i) reducing raw material and waste disposal costs, (ii) revenue opportunities for processing of residue that was used as heating fuel before, (iii) carbon emission reduction – carbon tax saving, and (iv) higher plant efficiency and lower cost.
