State Grid-Built Transformer Substation in Laos to Start Operation This Year

The Pala 500-kilovolt transformer substation in Laos will go into operation by the end of this year, China Southern Power Grid (CSG) announced on Sept 5.

A key part of the 500-kV high-voltage power transmission and distribution line network in 10 provinces in the northern and middle parts of Laos, the project is equipped with three main transformers with a total capacity of 750 megavolt-amperes.

Once operational, it will contribute to the construction of a large-capacity and highly-efficient cross-border power transmission passage linking China, Laos, Thailand and Vietnam. It will establish itself as a major "storage battery" for power in the southeast Asia region.

The substation is a key part of the 500-kV Xieng Khouang-Naxaythong power transmission and distribution project, which is part of the Laos 7th Five-Year Plan (2011-15) and the Belt and Road Initiative and valued at about $622 million.
