This is the third order for ANDRITZ HYDRO from Song Da Corporation, the largest Vietnamese civil construction company with a long history in hydropower plant construction in Vietnam and Laos. It follows the Laotian projects HPP Xekaman 3 (250 MW, completed in 2013) and HPP Xekaman 1 (290 MW, signed in 2013). All three projects are based on a bilateral governmental agreement between Laos and Vietnam for the joint development of hydropower plants. In all these projects Song Da is the main shareholder, EDL (Electricité du Laos) holds the minority interests.

Commissioning is scheduled for the second half of 2017, only 26 months after the contract commencement. The project will be executed by an international team of ANDRITZ HYDRO in Austria and China.

This contract marks another important milestone for ANDRITZ HYDRO in Laos as well as with the esteemed client Song Da Corporation.
