INDONESIA - In the Indonesian islands, a great subduction plate boundary 4000 km long between the Eurasian and Australian plates has formed nearly 200 volcanoes and 100 geothermal fields. Geothermal development started in the 1920s with the first shallow steam wells drilled at Kamojang. This field, which produced 250 kWe in 1979, has been producing 140 MWe from dry steam since 1985. The 1990s will show a great expansion. Salak (on line in 1994) now produces 110 MWe, Dieng (surrounded by ancient temples), 52 MWe and Lahendong, 2.5 MWe. Fields scheduled to start or expand by 1999 include: Kamojang (60 MWe), Dieng (95 MWe), Salak (220 MWe), Bedugul (110 MWe), and five other fields with 55 MWe or less (745 MWe total). Geothermal power in Lahendong (12.5 MWe) will encourage local industry in this remote district. 10 MWe of small (35-1000 kWe) "mini-geo" plants are planned for isolated villages. Natural steam and hot water are also used locally for cooking and bathing.
