Despite of the very promising potential of the country, located on the African rift geothermal anomaly, in Ethiopia since 1999 no new plant has been realized, and the 7.3 MW unit installed at Aluto-Langano field (Ethiopian Electric Power Corporation), after several operational problem, is currently producing for about 3 MW (figure 16), from a reservoir with 300°C at 2,000 m depth.
The second proven field of the country (Tendaho, 250°C at shallow depth) has a feasibility project for about 20 MW.
Six additional geothermal prospects have been launched, but the lack of foreign investors is the most important limiting factor for the future development in this country.

Teklemariam and Kebed (2010) provide details on geothermal fields and on development for power generation, but little data on direct-use.
They list seven bathing swimming facility using geothermal energy, mainly in Addis Abba. These include the Sheraton, Filowh, Ghion, and Hilton hotels, the National Palace, Greek Community, and St. Joseph School.
Based on this paper and on calculations made by one of the authors (Lund), the installed capacity is estimated at 2.2 MWt with an annual use of 41.6 TJ/yr.
