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, consisting of 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 Laos section is constructed by a joint venture between China Southern Power Grid Company and the Laos National Electricity Company, known as Laos National Transmission Grid Co., Ltd [2]. Group 2: Project Impact - The project has a dual-direction power transmission capacity of 1.5 million kW and is expected to deliver approximately 30 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' future electricity supply and regional economic development, especially with the upcoming industrial facilities in Udomxay Province [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 and posed risks during foundational work [4]. - The construction team adopted a flexible approach to construction scheduling and innovative foundation designs to ensure the project progressed smoothly despite the challenging 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 vegetation 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 [6]. - The project aims to cultivate local operational and maintenance talents to ensure the sustainable development of Laos' electricity sector [6].
