Successful installation of the Rotor of the generating unit No 3 of the Lai Chau Hydropower Plant Project

At 10.45 on September 06, 2016, the generator rotor of the unit No 3 of the Lai Chau hydropower plant project was successfully installed on its foundation by the Vietnam Electricity after 2 hours and 40 minutes to move into position.

The generator rotor of the unit No 3  is of  1,000 tons in weight , 15.587 m diameter and  2.816 m in height. It is one of the heaviest structure of the equipment installed at site. Before installing the rotor, the contractor has completed the installation of the turbine, stator, crane ... This is an important milestone, the reprequisite to commission the equipment   system, to meet the target of generationg the unit No 3 of the Lai Chau hydropower plant project  in November 2016 and inauguration of the whole project in December 2016.

The Lai Chau hydropower project is one of the projects on the Da river cascade.  The objective  of the project is to provide electricity to the national power system, contribute together with other hydropower plants on the Da River cascade for the flood control in the rainy season, the water supply in the dry season for the Northern Plain, serving social and economic development of the provinces of  Lai Chau,  Dien Bien  and the Northwestern area.  

The main parameters of the power plant project: normal water level of the reservoir is 295 m, the dead water level is 265m; the total capacity of the reservoir is 1,215 million m3; the crest of the gravity concrete dam is 137 m in height;  the spillway consists of two deep discharge gates and  and 6 surface radial gates; the power house consists of 3 generating units  with total installed capacity of 1,200 MW;  average energy for many years is 4,670.8 million kWh.
