Core Viewpoint - The completion of three key renewable energy projects by State Grid Inner Mongolia Electric Power Construction Management marks the successful establishment of a transmission channel for the 1 million kilowatt wind-storage base in Inner Mongolia, which will deliver 3.6 billion kilowatt-hours of renewable energy annually to East China, significantly reducing coal consumption and carbon emissions [1][3][11]. Group 1: Project Overview - The three completed projects include the 500 kV new energy gathering and transformation project at Taohomu, the 500 kV line project connecting Tongliao and Xingan, and the 220 kV outgoing project from the 1 million kilowatt wind-storage base in Keyou Zhongqi [3][9]. - The total investment for these projects is 1.69 billion yuan, involving the construction of one new 500 kV substation, 338.96 kilometers of 500 kV lines, and 116.9 kilometers of 220 kV lines, enhancing the capacity for renewable energy integration [3][5]. Group 2: Construction Efficiency - State Grid Inner Mongolia Electric Power has implemented a collaborative approach to ensure timely project operation, establishing a "point-to-point" communication mechanism to quickly resolve issues and facilitate continuous construction [5][7]. - The construction of the Taohomu 500 kV project achieved remarkable efficiency, completing feasibility studies in 39 days and obtaining approval in just 10 working days [5][7]. Group 3: Integration into National Grid - The projects are designed to connect the 1 million kilowatt wind-storage base to the national grid, optimizing electricity distribution across the country and enhancing the economic advantages of resource-rich areas [11][13]. - The integration into the national grid will facilitate the optimal allocation of electricity resources nationwide, ensuring stable power supply while promoting the green transformation of economically disadvantaged regions [11][13]. Group 4: Environmental Impact - The renewable energy projects are expected to save over 1.2 million tons of standard coal and reduce nitrogen oxides and carbon dioxide emissions by approximately 3.2 million tons annually [1][3]. - The cumulative external power transmission from the completed ultra-high voltage projects has exceeded 730 billion kilowatt-hours, equivalent to the annual electricity consumption of 280 million households, contributing to significant carbon emission reductions [3][11].
