In December 2025, the 500MW/2000MWh energy storage project was successfully grid-connected in Dengkou, Inner Mongolia. The energy storage station, standing proudly under the winter sun, is the first GWh-level project delivered by JD Energy. It not only set a new record for the scale of a single project but marked a significant milestone in the company’s development with its outstanding construction achievements.
01. 500MW/2000MWh: JD Energy enters the GWh-level project delivery
The 500MW/2000MWh energy storage project in Dengkou, Inner Mongolia, the first GWh-level project of JD Energy, utilized the company’s newly developed string-type prefabricated cabin, Galaxy-1. The project has an installed capacity of 500MW/2000MWh, deploying 400 units of Galaxy-1-4G and 100 units of eLink-HV35, a combined inverter and transformer.
In the harsh environment of sandstorms and cold temperatures, Galaxy-1 was used for the first time in a large-scale application on the grid-side. Despite the swirling yellow sands and biting winds, Galaxy-1 has laid a solid foundation for the new energy paradigm of Inner Mongolia with its exceptional environmental adaptability and operational stability.
02. Innovation empowerment: String-type prefabricated cabin Galaxy-1’s successful debut
The successful implementation of the 500MW/2000MWh energy storage project in Dengkou is driven by the flagship new product of JD Energy, the string-type prefabricated cabin Galaxy-1. This product adopts “All In One” design concept, integrating systems including 314Ah lithium iron phosphate (LiFePO4) batteries, BMS, string-type PCS, fire protection system, thermal management system, power distribution and communication system into a standard 20-foot container. It boasts key advantages of high efficiency, high safety and high integration. Through the successful practice of Dengkou project, Galaxy-1 made its debut on the grid-side, verifying its reliability and excellency in large-scale application.
With eMind-Trader as its core software system, JD Energy played a central role in supporting Dengkou power station’s operations from grid connection, market entry to autonomous participation in power trading, realizing a full value chain from system integration and project delivery to smart operation. This comprehensive technological advantage covering both hardware and software can not only significantly enhances the regional integration of new energy but also maximizes the project’s full lifecycle returns, achieving both stability and economic benefits.
03. Energizing the desert: green power driving regional development
At the turn of the year, Inner Mongolia has witnessed a surge in the grid connection of energy storage projects with energy constantly flowing. The successful grid connection of the 500MW/2000MWh energy storage project in Dengkou can effectively mitigate the fluctuations of intermittent renewable energy power generation of wind and solar power and significantly improve the grid’s adjustment capabilities and operational safety, providing more stable and higher-quality green electricity for Inner Mongolia and the North China region.
Meanwhile, the project will greatly increase the region’s ability to absorb renewable energy, reducing wind and solar curtailment. It will reinforce the energy transformation in Inner Mongolia and advance the national strategic goals of carbon peaking and carbon neutrality.
The successful grid connection of the 500MW/2000MWh energy storage project in Dengkou, Inner Mongolia marks JD Energy’s successful breakthrough in delivering a GWh-level single-project. It embodies the power of JD Energy with the debut of its flagship new product Galaxy-1. Moving forward, JD Energy will continue to innovate and explore energy storage sector, leaving a solid mark on the vast energy landscape while accelerating the progress of China’s energy revolution.
