He said the Lao electricity industry has become an important foundation for national socio-economic development, “allowing us to increase production of goods and transform production methods, so actively helping to improve living conditions and reduce poverty for our entire people”.
THPC, which has invested US$720 million in the expansion project, is 60% owned by EDL-Generation, with Thailand’s GMS Power and Statkraft of Norway each holding 20% of the company.
