Stung Tatay Hydropower Project, Cambodia

The Stung Tatay Hydroelectric Project is situated on the Tatay River in Koh Kong Province in the south-western part of the Kingdom of Cambodia.

The project comprises two concrete faced rockfill dams (CFRD), a gated overflow spillway with chute and flip bucket, an approx. 11 km long headrace tunnel of 8.0 m diameter and a surface powerhouse with an installed capacity of total 246 MW (3 Francis-turbines of each 82 MW).

The two dams which are located beside each other impound a reservoir with a total storage capacity of approximately 439 million m³. The active storage volume is about 322 m³.
