Laos Commences Construction of a Key Laos transmission line
In a significant step towards enhancing its national energy infrastructure, Laos has officially commenced the construction of a new 230 kV transmission line. This major project will connect the northern provinces of Luang Prabang and Xieng Khouang, marking a key development in the country’s energy sector.
The initiative is a collaborative effort between the state-owned Electricité du Laos and China Electric Power Equipment and Technology, a subsidiary of the State Grid Corporation of China. This partnership underscores the project’s importance for both national development and regional cooperation.
Project Scope and Specifications for the Laos transmission line
The new double-circuit transmission line will span a distance of 186 kilometers. It is designed to link the Pak Mong 2 substation in Luang Prabang with the Na Phia substation in Xieng Khouang. The project also includes the expansion of both substations, with plans to add two new bays at each facility to accommodate the increased capacity.
The route of the transmission line will traverse a total of nine districts across the two provinces, including:
* Nambak
* Pak Ou
* Pak Seng
* Luang Prabang City
* Phonxay
* Phou Khoun
* Phoukoud
* Pek
* Phaxay
Strategic Importance for the Laos transmission line
This transmission line is a cornerstone of Laos’ 2024–2030 national energy development plan. The primary objective of the project is to strengthen the country’s high-voltage transmission network, ensuring a more stable and reliable power supply for residents and businesses in the northern region.
Furthermore, the Luang Prabang–Xieng Khouang line is poised to play a crucial role in enhancing regional grid connectivity. By improving its domestic power infrastructure, Laos continues to solidify its position as a key player in the regional energy market, often referred to as the “Battery of Southeast Asia.” This development will facilitate more efficient power distribution within the country and support greater energy exchange with its neighbors. The project represents a forward-looking investment in the nation’s economic and energy future.
