at 11: 00 a.m. on December 31, 2025, Huaneng jingshun Yecheng 200000 kw/800 million h grid-type energy storage power station was successfully connected to the grid. this project is the first new independent energy storage power station in Yecheng county, achieving a local zero breakthrough in this field. After the project is put into operation, it can not only achieve efficient energy storage and accurate scheduling, but also have a strong power grid transmission capacity, which can effectively alleviate the ability of power grid peak regulation and supply in southern Xinjiang.

Huaneng Jingshun Yecheng Energy Storage Power Station provides virtual inertia and short-circuit capacity for the power grid through grid-type control technology, effectively solves the contradiction between regional power supply and demand, and provides a solid and reliable power guarantee for Kashgar's economic growth. The power station adopts the self-synchronous operation technology of virtual synchronous machine and power grid, which has the functions of inertia support and primary frequency modulation, and significantly improves the system stability. At the same time, it is equipped with a full-scene energy management system to realize the efficient operation and maintenance technology of "few inspection, unattended, and fault self-healing", with an effective utilization rate of 99.9 percent.

Yu Qinglong, project manager of Huaneng Jingshun Yecheng, said: "The successful grid connection of Yecheng's 200000 kW/800 million h network energy storage project is an important achievement for enterprises to practice the concept of green development and deeply cultivate Xinjiang's energy market. The project consumes 0.25 billion kWh of clean energy every year, reducing carbon dioxide emissions by about 200000 tons, sulfur dioxide by 600 tons, and nitrogen oxides by 550 tons. In the future, the company will continue to focus on the optimization and upgrading of grid-based energy storage technology and scene expansion, and give full play to the comprehensive advantages of the project in peak regulation and frequency regulation, emergency supply protection, green power consumption, etc., to provide more solid support for the transformation of energy structure and the safe and stable operation of the power grid in southern Xinjiang."

The power station design takes into account efficiency and environmental protection, and adopts modular standardized energy storage units to support rapid deployment and expansion. The use of lithium iron phosphate battery, long cycle life, with multiple safety protection measures to ensure that the safety level of the power station standard. After the project was put into operation, it effectively alleviated the peak and valley leveling of the load of Kashi power grid and ensured the stable supply demand of people's livelihood.

Liu Jianglin, the second-level chief staff member of the Yecheng County Development and Reform Commission, said that the core highlight of the project lies in the large-scale application of new network-type technology. The commissioning of the project has greatly improved the peak shaving and supply capacity of the southern Xinjiang power grid. After it is put into operation, 0.25 billion kWh of peak-shaving green electricity can be added every year, which is equivalent to meeting the annual electricity demand of 120000 households, effectively solving the problem of "difficulty in consumption" of new energy, effectively reducing the high rate of light and wind abandonment of new energy in southern Xinjiang, and laying the foundation for the subsequent development and construction of large-scale new energy projects in Yecheng County. At the same time, it also promotes the coordinated development of the upstream and downstream of the energy storage industry chain, laying a solid foundation for Yecheng County to build a green development model of "new energy + energy storage.
