Largest hydropower plants in the Gulf, South Asia and South East Asia

1,442 hydro records carry a capacity figure: 343.0 GW in total, of which 170.0 GW across 1,039 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 hydropower 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 hydropower plants

What is the largest operating hydropower plant in the Gulf, South Asia and South East Asia?+

By capacity on record, Terbela Power Station in Pakistan at 4,888 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 hydropower plant planned or under construction in the region?+

Siang Upper hydroelectric plant in India at 10,000 MW, at concept stage. Announced capacity is kept in a separate list from operating capacity here because the two are different kinds of fact: 170.0 GW of the 343.0 GW on record for hydro is running.

How is this ranking compiled?+

From 1,442 published hydro 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.

Other rankings: solar plants, wind farms, energy storage projects, nuclear power plants, geothermal plants, bioenergy plants.
