Grindley, G.W. 1965 The geology, structure, and exploitation of the Wairakei Geothermal Field, Taupo, New Zealand. Wellington: New Zealand Geological Survey. New Zealand Geological Survey bulletin 75 130 p.
Abstract: This bulletin describes the geological aspects of a 15-year investigation of the geothermal resources of the Wairakei hydrothermal field, carried out jointly by the New Zealand Ministry of Works and the D.S.I.R. Since 1950, 120 drillholes (to a maximum of 4,550 ft) have been drilled, and a power station, steam transmission lines, and ancillary structures constructed. Power generation commenced in 1958 and present peak output is 175 MW at 85-90% load factor. Installed capacity is 192 MW, giving a plant factor of 70-90%. (auth)
