Summary

(1)　 The Inner Mongolia Power Corporation Baotou Power Supply Company submitted the Environmental Impact Report for the Urad Middle Banner De'ergengshan New Energy Storage Power Station Project, a demonstration project for concentrated energy storage using sodium-ion batteries, and the 220kV Grid-Side Concentrated Energy Storage Demonstration Project. After reviewing the report, the following opinions were reached.

(2)　 The project involves the construction of a 500kV substation at De'ergengshan, with a 220kV transmission line connecting to the Shuier De'ergengshan Energy Storage Substation. The project will also involve the construction of new transmission lines, including a 0.2km line connecting the De'ergengshan Energy Storage Substation to the Shuier De'ergengshan Energy Storage Substation, a 1km line connecting the De'ergengshan Substation to the Shuier De'ergengshan Energy Storage Substation, and a 0.8km section of the 220kV Debao line.

(3)　 The project will be located in the Urad Middle Banner, Baotou City, Inner Mongolia Autonomous Region. After considering the environmental impact, the Environmental Protection Bureau of Inner Mongolia Autonomous Region has approved the project, subject to the implementation of the environmental protection measures outlined in the report.

(4)　 During the construction and operation of the project, the following measures must be taken:

(5)　 1. Environmental protection measures must be strictly implemented during the construction and operation phases, and ecological protection and restoration work must be completed. 2. The environmental impact of electromagnetic fields and noise pollution must be strictly controlled and monitored to meet the relevant national standards. 3. The construction and operation phases must meet the environmental impact report's requirements for noise pollution and prevention measures, and the monitored values must meet the national evaluation standards.

(6)　 After the project is completed, the construction unit must undergo an environmental impact assessment and obtain approval before it can be put into operation. The Baotou City Environmental Protection Bureau has been entrusted with the responsibility of supervising the construction phase of the project.
