Questions about geothermal in Indonesia

What is the largest geothermal plant in Indonesia?+

The largest operating geothermal plant on record in Indonesia is Darajat geothermal power plant 3.0 at 129 MW, developed by Star Energy Geothermal. Ranked by the capacity figure in the public source named on the record, whole project rather than any partner's share.

What is the largest geothermal plant planned in Indonesia?+

Patuha geothermal power plant 2026-04-08 00:00:00 at 290 MW, at concept stage. Of the 6.0 GW of geothermal on record for Indonesia, 2.7 GW is operating; the rest is announced or being built.

How many geothermal plants does Indonesia have?+

Solandor holds 113 geothermal records for Indonesia with a stated capacity, 56 of them operating. That is the public record from the datasets named on each row, not a census: small plants below tracker thresholds are missing from the sources and so from here.
