Construction work has started on the 2.24GW Yebatan hydropower project on the Jinsha River in the Tibet Autonomous Region.

According to reports from the Xinhua news agency, a cofferdam was built for diversion purposes above the site on Saturday.

The project is being built by China Huadian Corporation at the junction of Baiyu County in southwestern Sichuan Province and Konjo County. It is expected to cost around US$5 billion, with the first unit at the plant scheduled to go online in 2025.

Once complete it will be the largest hydropower project on the upper reaches of the Jinsha River.
