Core Viewpoint - The construction of ultra-high voltage power grids in Xinjiang is crucial for supporting the integration and long-distance transmission of renewable energy, contributing to China's dual carbon goals and environmental protection efforts [2][3][4]. Group 1: Renewable Energy Development - Xinjiang has accelerated the construction of renewable energy bases, with major projects in Hami, Changji, and Urumqi, leading to the establishment of multiple million-kilowatt wind and solar projects [2]. - By 2025, Xinjiang plans to build and continue 41 ultra-high voltage projects, a 50% increase from 2024, marking a historic high in power grid construction [2]. - As of now, Xinjiang has built 31 750 kV substations and 92 transmission lines, totaling 12,705 kilometers, making it the province with the most 750 kV substations and longest lines in China [2]. Group 2: Energy Transmission and Environmental Impact - Since the launch of "Xinjiang Power Transmission" in 2010, several ultra-high voltage direct current transmission projects have been completed, significantly supporting national energy resource optimization and carbon reduction goals [2]. - In the first quarter of 2025, the electricity transmitted from Xinjiang reached 32.4 billion kilowatt-hours, a 13% year-on-year increase, with renewable energy accounting for 24% of this total [3]. - The upcoming Hami-Chongqing ±800 kV transmission project is expected to deliver 36 billion kilowatt-hours annually, with over 18 billion kilowatt-hours sourced from wind and solar, reducing coal consumption by 6 million tons and CO2 emissions by 1.65 million tons [2]. Group 3: Ecological Protection Measures - The construction of the ultra-high voltage grid in Xinjiang is designed to prioritize ecological protection, with measures taken to minimize environmental impact during the construction process [4][5]. - Detailed ecological surveys and the use of remote sensing and big data technologies have been employed to create tailored ecological protection and restoration plans for various projects [5]. - Innovative techniques, such as using biodegradable materials for sand fixation and protective measures for rare species, have been implemented to ensure the preservation of local ecosystems during construction [5][6].
