1. All dolo except levelized electricity costs ore Ioken from: Short, William (November 1991} uends in the lunedcon Geothermal Energy lndusfly, Geothermal Resource Council
Bulletin. Costs will vary according In fluid temperatures and related thennol efficiencies and the conversion technologies used. The copocity per inslnllofion represents the over·
age size of existing facilities. The operating experience of some geothennol technologies is hmited; reseiVoir life expecloncies ore on important unknown. The corrosive and scof
ing potentiol of geothennol fluids is o snrrkont limiting foclor on plont life expectancy. Even though monufocturers try In achieve useful lives of 20 to 30 yeors, more operating
experience is needed to determine if such goals con be attoined.
