Tunnel breakthrough imminent in Vietnam hydro plant

Cavico is expected to make the third and final tunnel breakthrough at the A Luoi Hydropower project in Vietnam next month.

Once complete, the 170MW hydropower plant is expected to generate about 686 million kWh of energy annually.

Cavico created a 7.27 mile-long and 21.3 feet-wide headrace tunnel and broke through the first and second sub-tunnels in August and December last year.

The plant, built on the A Sap River in Thua Thien Hue Province in central Vietnam, is owned by Central Hydropower.
