跨国“电力高速路”，跑出发展加速度（共建“一带一路”·第一现场）

Core Viewpoint - The completion of the China-Laos 500 kV interconnection project marks a new phase in energy cooperation between China and Laos, with both sides working towards synchronized operation by April [2][3]. Group 1: Project Overview - The China-Laos 500 kV interconnection project connects Yunnan Province in China with Udomxay and Luang Namtha Provinces in Laos, comprising a 145 km section in China and a 32.5 km section in Laos, making it the largest and highest voltage cross-border power grid project between the two countries [3][4]. - The project is a joint venture between China Southern Power Grid Company and the Laos National Electricity Company, established to invest in and construct the Laos section [3]. Group 2: Project Significance - Once completed, the project will have a bi-directional power transmission capacity of 1.5 million kW and will deliver approximately 30 billion kWh of clean electricity annually, significantly enhancing Laos' grid regulation and supporting the development of clean energy and industrial projects [4][5]. - The project aims to lay a foundation for the stability of Laos' future electricity supply and regional economic development, especially with the upcoming industrial demands from new factories in Udomxay Province [5][6]. Group 3: Construction Challenges and Solutions - The construction faced challenges due to Laos' mountainous terrain and tropical rainforest, which limited the effective construction window and posed risks during foundational work [5]. - The construction team adapted by scientifically adjusting the construction schedule and employing innovative methods to ensure the project progressed smoothly while prioritizing ecological and community considerations [5][6]. Group 4: Local Workforce Development - Over 500 local employees have been hired for the project, with a focus on bilingual safety training and practical skills enhancement to ensure safe construction and operation [6]. - The project aims to cultivate local operational capabilities, contributing to the sustainable development of Laos' electricity sector [6].
