Dongfang Electric International Corporation has built eight hydropower development projects in Laos over recent years.
These projects include Nam Dong Hydropower Plant Rehabilitation Project, Nam Ngiep 3A Hydropower Project and Nam Sane 3A and 3B Hydropower Projects, said Mr Wang Ai, Plant and Project Division No.2 General Manager, Dongfang Electric Corporation (DEC).
Based in Chengdu, the capital city of Sichuan Province, DEC is one of the most influential enterprise groups under the direct administration of Chinese Central Government.
DEC has developed strong cooperation with the Lao government over the past years.
Early this year, DEC signed an energy performance contract (EPC) for the 120-MW Nam Mo II Hydropower Project in Laos.
As the first high water head impulse unit power station in the country, the project, once completed, will greatly alleviate the local shortage of electricity and accelerate social and economic development in Laos and its neighbour Vietnam, DEC posted on its website.
Many dams have been constructed in Laos over recent years but over coming five or six years Laos needs to develop transmission lines networks in order to export more electricity to China, Vietnam, Cambodia and Thailand, said Mr Wang Ai.
Today, 250-kilowatt voltage transmission line needs to be upgraded to 500 kilowatts so that more electricity can be exported, he went on.
Over the last few years, the power sector has grown very quickly. Now, the produced power not only meets the local market demand but is also exported to neighbouring countries. This is an amazing achievement, said Wang, a Chinese senior engineer who has visited Laos for many times.
