Under the new contract Cavico’s majority-owned subsidiary, Cavico Power & Resource, will be responsible for the construction of the sub headrace tunnel No. 2, a water diversion tunnel and a surge sharp tank at the 180MW project.

The Hua Na hydro power plant, a twin turbine plant which requires a capital investment of approximately $250M, is located on a 20.6km2 property in the Dong Van village of the Nghe An province near the Chu River. Once completed, the hydropower plant is expected to supply 706M kWh annually.

Cavico signed an initial contract for $4.9M with Lilama for construction work at the project back in April 2009, including constructing a diversion tunnel and cofferdam.
