en.Wedoany.com Reported - The 215MW/860MWh energy storage project of the seventh section of the Tibet Mamiso Source-Grid-Load-Storage Integrated Energy Station has completed construction and commissioning, officially meeting the conditions for energization, filling the gap in large-scale independent energy storage facility construction in northern Tibet. Located on the edge of the uninhabited area of Mami Township, Gaize County, Ngari Prefecture, Tibet, the project has a total energy storage capacity of 215MW/860MWh, equipped with battery compartments and power conversion systems, covering the entire construction process including civil works, electrical systems, commissioning, and security. As a core energy storage hub in northern Tibet, the project can support wind and solar power integration, grid peak shaving, and voltage regulation, demonstrating exemplary value for implementing the "dual carbon" strategy and building a new power system.
The project signed the general contracting contract at the end of April, with an effective construction period of only over 50 days. Facing multiple pressures such as a tight schedule and cross-disciplinary construction, the project department coordinated resources, implemented parallel construction in zones, and worked day and night, balancing construction progress and quality. The site is at an altitude of 4,700 meters, with severe cold, oxygen deficiency, and frequent strong winds, significantly increasing personnel workload and reducing equipment performance. Material transportation over long distances on rugged roads posed challenges for supply assurance. The tight sequencing of processes left little room for error, compounded by special conditions such as frozen soil and sandstorms, increasing the difficulty of quality and safety management. The project department strengthened its primary responsibilities, dynamically optimized construction organization plans, ensured advance material and equipment supply, implemented closed-loop schedule management, strictly enforced a three-tier quality inspection system, and rigorously managed safety production and civilized construction. All construction personnel remained on the front line, working in shifts continuously, resolving bottlenecks and difficulties one by one, achieving zero safety accidents and zero quality risks throughout the process, and completing all construction tasks on schedule with high standards.
The project is implemented by Sinohydro Bureau 5 Co., Ltd. The bureau stated that it will continue to establish a strong presence on the snowy plateau, deepen its involvement in the western new energy business sector, and provide support for the regional green and low-carbon energy transition.
