THE FEASIBILITY OF GEOTHERMAL POWER PLANT IN INDONESIA
(CASE STUDY: 165 MW OF NGEBEL GEOTHERMAL POWER PLANT)
find this pdf - quite comprehensive, detailed wells 200C at 500 meters.

if you look harder you will find the sokoria/mutubusa pre feasibility by JICA - looks good to me. sokoria has a gradient of 38DegC per 100m depth...
