春节前夕，中老500千伏联网工程输电线路全线贯通—— 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 [1][2]. 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 [2]. - 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 [2]. 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 3 billion kWh of clean electricity annually, significantly enhancing Laos' grid regulation and supporting the development of clean energy and industrial projects [3][4]. - The project aims to lay a foundation for the stability of Laos' electricity supply and regional economic development, particularly as local industrial electricity demand is expected to increase with the establishment of new factories [4]. Group 3: Construction Challenges and Solutions - The construction faced challenges due to Laos' mountainous terrain and tropical rainforest, which limited the effective construction window during the long rainy season [4]. - The construction team adapted by adjusting the construction schedule and employing innovative foundation designs to ensure the project progressed smoothly despite the complex geological conditions [4]. Group 4: Environmental and Community Considerations - The project emphasizes ecological protection and community welfare, with efforts made to avoid sensitive ecological areas and minimize impacts on biodiversity and local communities [4]. - New compact towers and local plant species for landscaping in substations were prioritized to enhance environmental sustainability [4]. Group 5: Local Workforce Development - Over 500 local employees have been hired for the project, with bilingual safety training and practical skills training provided to enhance their professional capabilities [5][6]. - The project aims to cultivate local operational and maintenance talent to ensure the sustainable development of Laos' electricity sector [6].
