Abstract: A growth trend in geothermal investment in New Zealand continues. The following achievements were noted for 2010 geothermal activities. Research into hotter and deeper resources and low enthalpy resources continues. At Rotokawa the Nga Awa Purua 140 MWe triple flash plant and at Tauhara the Te Huka 23 MWe binary plant were commissioned. The Te Mihi 166 MWe project to replace 45 MWe of old Wairakei plant was confirmed. A direct use expansion (32 MWth, 300 TJ/yr) at Kawerau for the SCA paper mill was commissioned. Construction of a further direct use application (270 TJ/yr) at Mokai, for a dairy milk processing factory, commenced. At Ngatamariki, construction plans were confirmed for an 82 MW binary plant. At Tauhara, a 250 MWe consent application was approved. There has been an on-going high level of deep geothermal drilling. Exploration drilling of a new 'greenfield' prospect at Taheke is underway. Plans were confirmed for an embedded 20 MWe expansion at Kawerau (NST). Other future plans include: 50 MW at Kawerau (Ka22), 35MW at Rotoma, 45MW at Tikitere and possibly 50MW at Taheke. (auth)
