Questions about hydro in Thailand

What is the largest hydropower plant in Thailand?+

The largest operating hydropower plant on record in Thailand is Lam Ta Khong at 1,000 MW, developed by Electric Generating Authority of Thailand. Ranked by the capacity figure in the public source named on the record, whole project rather than any partner's share.

How many hydropower plants does Thailand have?+

Solandor holds 20 hydro records for Thailand with a stated capacity, 20 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.
