Core Viewpoint - The China-Laos 500 kV interconnection project has achieved full line connectivity, enhancing bilateral electricity exchange capabilities and promoting clean energy transmission [1] Group 1: Project Overview - The project connects Laos' Udomxay and Luang Namtha provinces with China's Yunnan province, consisting of a 145 km domestic section and a 32.5 km section in Laos [1] - The project is jointly invested in by China Southern Power Grid Company and the Laos National Transmission Grid Company [1] - Upon operation, the project will enable a bi-directional electricity exchange capacity of 1.5 million kW, delivering approximately 3 billion kWh of clean electricity annually [1] Group 2: Environmental Considerations - The construction area traverses ecologically sensitive regions, including a tropical rainforest protection zone and the only Asian elephant habitat in the country [1] - Innovative measures during construction led to a reduction of 15 cableway installations and over 80,000 square meters of temporary land occupation, preventing the felling of more than 30,000 trees [1] - Disturbance to the protected area was reduced by over 90%, effectively avoiding core areas of forest and regions rich in biodiversity, ensuring minimal ecological impact from the project [1]

Core Viewpoint - The construction of the Aba 1000 kV UHV substation in Miyaruo Town, Sichuan Province, is facing challenges due to heavy snowfall, but efforts are being made to ensure timely completion by optimizing work processes and clearing snow [6] Group 1: Project Details - The Aba to Chengdu East 1000 kV UHV AC transmission project is scheduled to be completed and operational by the end of 2026 [6] - The new Aba 1000 kV substation will set records for the highest altitude, highest fill slope, largest earthwork volume, most complex geology, and most complicated access roads and water sources for UHV substations [6] Group 2: Regional Impact - The project aims to transmit abundant clean energy from the western Sichuan region, including hydropower, wind, and solar energy, to the load centers in the Chengdu urban agglomeration [6] - This initiative is expected to significantly support the construction of the Chengdu-Chongqing economic circle [6]
