Largest geothermal plants in the Gulf, South Asia and South East Asia
193 geothermal records carry a capacity figure: 11.5 GW in total, of which 6.7 GW across 107 records is operating. Two lists, because a running plant and an announced one are not the same kind of fact. Every row links to its record and its public source.

Largest geothermal plants under construction or announced
Capacity as announced by the source. A concept-stage figure means a public source names the project and a number, nothing more.

Questions about the largest geothermal plants
What is the largest operating geothermal plant in the Gulf, South Asia and South East Asia?+
By capacity on record, Unified Leyte in the Philippines at 610 MW. Solandor ranks operating plants by the capacity figure in the public source named on each record, whole project rather than any partner's share, and does not adjust for phased commissioning unless the source records the phases separately.
What is the largest geothermal plant planned or under construction in the region?+
Patuha geothermal power plant 2026-04-08 00:00:00 in Indonesia at 290 MW, at concept stage. Announced capacity is kept in a separate list from operating capacity here because the two are different kinds of fact: 6.7 GW of the 11.5 GW on record for geothermal is running.
How is this ranking compiled?+
From 193 published geothermal records that carry a capacity figure, sorted by that figure. Each record names the public dataset it came from and links the page it was taken from. Records without a stated capacity are not ranked; a missing figure is not zero.
