浙江“十五五”首条500千伏送出工程投运

Core Viewpoint - The successful completion and operation of the 500 kV transmission project for the Qujiang Pumped Storage Power Station in Zhejiang marks a significant milestone for the integration of renewable energy into the Zhejiang power grid, contributing to the province's green and low-carbon development [1][3]. Group 1: Project Overview - The project spans approximately 37.651 kilometers and includes the installation of 107 transmission towers, passing through 17 villages in Qujiang District and Longyou County [1]. - The construction faced challenges due to its location in ecologically sensitive areas, including ecological red lines, water source protection zones, and scenic spots, making the project complex and difficult [1][2]. Group 2: Engineering and Design Challenges - The design team employed technology and meticulous planning to address construction challenges, ensuring safety and quality while balancing ecological protection [2]. - Specific measures included detailed assessments, customized designs for tower configurations, and optimized transportation plans to minimize environmental impact [2]. Group 3: Environmental and Economic Impact - The Qujiang Pumped Storage Power Station is expected to generate 1.2 million kilowatts of clean electricity by 2026, with full production by 2027, leading to significant reductions in coal consumption and carbon emissions [3]. - The project is projected to save approximately 110,000 tons of standard coal and reduce carbon dioxide emissions by about 220,000 tons annually, equating to the ecological benefit of planting nearly 6 million trees [3].
