Survey of Energy Resources 2007
Geothermal Country Notes
Preliminary studies conducted in different parts of Tanzania by surface geological exploration, magnetic and gravity data analyses and reconnaissance exploration have indicated that the country possesses high-temperature (exceeding 200°C) fluids beneath the volcanoes.
The presence of hot springs has provided a positive indication of the country's geothermal potential. Fifty hot springs have been sampled, with the majority having a surface temperature of 86°C and a reservoir temperature of 220-276°C.
Presently the country's geothermal resource is not utilised. However, and especially in the light of an increasing energy requirement, the National Energy Policy 2003 highlights the need to assess the potential and establish its viability.
