New Energy Storage Capacity in the Xinjiang Power Grid Exceeds 20 Million Kilowatts

　　Urumqi, January 6 (China News Service) (By Yu Yanchun, Ding Biwei, and Ran Xiumin) — Reporters learned on the 6th from State Grid Xinjiang Electric Power Co., Ltd. that as of December 31, 2025, the installed capacity of new energy storage systems in the Xinjiang power grid reached 20,150,400 kilowatts / 70,537,600 kilowatt-hours, surpassing the 20-million-kilowatt milestone. This installed capacity ranks among the highest in the country, providing solid support for the efficient integration of new energy sources in Xinjiang and the safe and stable operation of the power grid, while also injecting Xinjiang’s momentum into China’s green and low-carbon energy transition and the nation’s overall energy security efforts.

 
　　Xinjiang is a key strategic base for national energy resources, blessed with exceptional wind and solar resources, and serves as a core region for China’s clean energy development and construction. As a major national energy production hub, Xinjiang has continued to accelerate the development of clean energy. By the end of 2025, the total installed power generation capacity of the Xinjiang power grid had exceeded 250 million kilowatts, of which new energy capacity reached 161 million kilowatts. Six 10-million-kilowatt-class new energy bases, including those in Hami and Zhundong, have been completed. The proportion of new energy in total installed capacity continues to rise, and the capacity to supply clean energy is steadily increasing. This breakthrough in new energy storage capacity marks Xinjiang’s accelerated transition from a major clean energy production hub to a powerhouse in energy storage and dispatch. The coordinated development of power generation, transmission, and storage has been further refined, and the quality and efficiency of clean energy development and utilization continue to improve.

　　Energy storage is a key component of the new power system and a core measure for addressing the intermittency and volatility of renewable energy generation while ensuring the efficient integration of renewable energy. Currently, the deployment of new energy storage in the Xinjiang power grid encompasses both renewable energy-associated storage and standalone storage, forming a diversified and complementary energy storage development system. Data shows that in 2025, the Xinjiang power grid’s new energy storage systems recorded an annual cumulative charging volume of 9.1 billion kilowatt-hours and a discharging volume of 7.7 billion kilowatt-hours, with an equivalent utilization of 1,733 hours. Through the peak-shaving, frequency regulation, and emergency standby functions of energy storage facilities, fluctuations in wind and solar power generation have been effectively smoothed out, significantly enhancing the grid’s capacity to integrate renewable energy and ensuring that renewable energy can be “generated, stored, and transmitted reliably.”

　　In recent years, the range of new energy storage technologies in the Xinjiang power grid has continued to expand. Lithium iron phosphate (LiFePO?) energy storage has been deployed on a large scale; demonstration projects for new energy storage technologies such as vanadium flow batteries and flywheel storage have been successfully implemented; and pilot applications of grid-forming and long-duration energy storage technologies are advancing rapidly. Continuous technological iteration and upgrades have consistently improved the safety performance and regulatory efficiency of energy storage facilities, transforming them into stabilizers for the safe operation of the power grid and catalysts for the efficient utilization of renewable energy, thereby laying a solid technological foundation for the construction of a new power system.

　　Moving forward, State Grid Xinjiang Electric Power will continue to optimize the service mechanisms for grid-connected energy storage, promote the demonstration and application of new energy storage technologies, and improve market-based trading mechanisms for energy storage. The company will steadily expand the installed capacity of new energy storage systems, enhance energy storage utilization efficiency, and continuously improve the quality and efficiency of the energy storage industry. By doing so, it will steadily advance the construction of the new power system and continuously enhance Xinjiang’s capacity for the optimal allocation of energy resources.
