Core Viewpoint - The completion and operation of the 330 kV Yushu Second Circuit Project marks a significant advancement in the Yushu power grid, transitioning it to a "dual-circuit" supply era, enhancing power reliability and capacity, and supporting local economic and social development [2][15]. Group 1: Project Overview - The Yushu Second Circuit Project was officially completed and put into operation on July 22, significantly improving the power supply reliability and capacity for the region [2]. - The project connects Yushu to the larger Qinghai power grid, ending the historical reliance on a single circuit supply and enhancing the overall network structure in the upper reaches of the Yellow River [2][6]. - The project involved the construction of two 330 kV lines and extensive coverage of 110 kV lines across Yushu, serving a population of 385,000 [6]. Group 2: Economic and Social Impact - The project is expected to facilitate the transition from "having electricity" to "using electricity well" for local residents, thereby boosting local economic activities and improving living standards [6][15]. - The introduction of stable electricity supply has led to the development of local businesses, such as the establishment of a homestay in Landa Village, which is part of the rural revitalization initiative [4][18]. - The project supports the clean heating transformation in Yushu, with plans to convert coal-fired boilers to electric ones, enhancing environmental quality [15]. Group 3: Environmental Considerations - The construction of the project was conducted with a strong emphasis on ecological protection, particularly in sensitive areas like the Sanjiangyuan National Nature Reserve [10][12]. - Innovative construction techniques were employed to minimize environmental impact, including the use of drones and specialized equipment to navigate challenging terrains [12][11]. - The project aims to restore the original landscape post-construction, with a commitment to ecological restoration and sustainable practices [10][12]. Group 4: Future Prospects - The successful operation of the Yushu Second Circuit Project is expected to attract further investment and development in the region, enhancing its appeal for businesses and tourism [17][18]. - The project lays a solid foundation for the development of renewable energy resources, such as wind and solar power, positioning Yushu as a key player in China's clean energy initiatives [15].
