Construction of China-Laos railway power supply project starts

Laos, Vientiane: The power supply project for the China-Laos railway, which was fully carried out on March 18, lays foundation for its scheduled operation in 2021.

The power supply project, running along the China-Laos railway through five provincial administrative regions in northern Laos, will build 20 circuits of 115 kV transmission lines with total length of 268 km and 635 power towers, and extend 11 bays in 10 substations, in order to supply power from the state-run Electricite du Laos grid to 10 railway traction substations.

The project for the China-Laos railway is the first BOT (build-operate-transfer) power grid project in Laos, a key project to guarantee the scheduled operation of the China-Laos railway and of building the China-Laos community with a shared future. It is also a symbolic project of the Belt and Road Initiative to advance infrastructure connectivity.

The project is invested and built by a joint venture, namely Laos-China Power Investment Company, co-sponsored by China Southern Power Grid (CSG) and the state-run Electricite du Laos, and implemented mainly by CSG’s engineering companies.

The CSG project team said that as a key process in the construction of transmission lines, the first foundation casting, has set a model for the construction technical standards and engineering safety standards, which is of great significance to ensure the quality of the project.

The 414 km railway, with 19 -km tunnels and 62 km bridges, will run from Boten border gate in northern Laos, bordering China, to Vientiane with an operating speed of 160 km per hour.

The project started in December 2016 and is scheduled to be completed and opened to traffic in December 2021.
