In a landmark development for regional energy cooperation, the Chinese and Lao sections of the 500-kV power interconnection project achieved physical connectivity on Thursday, February 5, 2026. This strategic infrastructure milestone represents the latest breakthrough in bilateral cooperation following the successful China-Laos Railway project.
The transnational transmission line spans 177.5 kilometers across both nations, with China Southern Power Grid Co., Ltd. constructing the 145-kilometer Chinese segment and Electricite du Laos Transmission Company Limited developing the 32.5-kilometer Lao section. The project’s completion establishes critical energy infrastructure between the neighboring countries.
Upon becoming operational, the interconnection is projected to facilitate bidirectional electricity transmission capacity of 1.5 million kilowatts, enabling the annual transfer of approximately 3 billion kilowatt-hours of clean energy. This capacity will significantly enhance regional power stability while promoting sustainable development through clean energy exchange.
The project extends physical connectivity beyond transportation into the energy sector, marking a new chapter in China-Laos economic cooperation. It strengthens regional infrastructure integration while supporting energy mix optimization and environmentally responsible development throughout the Southeast Asian region.
