“陇电入鲁”工程正式投运 年输送电量达360亿度

Core Viewpoint - The completion and commissioning of China's first large-scale integrated energy base project, the Longdong to Shandong ±800 kV UHVDC project, will significantly enhance the transmission of renewable and conventional energy from Gansu to Shandong, supporting energy resource optimization across regions [1][3]. Group 1: Project Overview - The UHVDC transmission line spans 915 kilometers, starting from Gansu and passing through Shaanxi, Shanxi, and Hebei, ultimately reaching Shandong [3]. - The project includes the construction of two converter stations in Gansu and Shandong, with a transmission capacity of 8 million kilowatts, capable of delivering over 36 billion kilowatt-hours of energy annually, sufficient to power over 10 million households for a year [3]. Group 2: Energy Composition - The total energy transmitted includes wind, solar, thermal, and storage power, with green energy accounting for half of the total [3]. Group 3: Strategic Importance - The project supports the development of large-scale wind and solar energy bases and their associated UHV projects, addressing the energy shortage in North China while optimizing the rich energy resources in the western regions [5]. Group 4: Environmental Considerations - To minimize the impact on native vegetation during construction, the project utilized a 2.07-kilometer freight cableway and detachable rotary drilling rigs, which were transported and assembled on-site [11]. - The construction team plans to replant 32 hectares of trees and sow 40 hectares of grass seeds in the areas affected by the construction of five transmission towers in the ecologically sensitive Ziwuling region [9][15].
