On December 30, the Hebei Wuqiang Hongbu Energy Storage Power Station—the first independent energy storage project in Hebei Province to adopt an AI-powered safety and operations system—was successfully connected to the grid.
With a total capacity of 200MW / 800MWh, the project was delivered with deep involvement from Far East Battery, which provided a full-scope energy storage system solution along with comprehensive and high-standard operations and maintenance services, ensuring high-quality execution from system design and engineering delivery to commissioning and grid connection.

After entering operation, the project will provide fast and reliable grid support through peak shaving, frequency regulation, and voltage regulation, significantly enhancing regional grid stability and renewable energy integration. Its commissioning represents a major upgrade in both safety-oriented operation and intelligent management for large-scale energy storage facilities in the region.

Highly Integrated System Architecture for Large-Scale Deployment

The Wuqiang Hongbu project consists of 40 energy storage units rated at 5MW / 20MWh each, connected to the 35kV side of a 220kV step-up substation via eight collector lines.
The overall solution includes:

• 160 units of 5MWh DC-side energy storage containers

• 40 sets of 5MW string-type PCS step-up integrated units

• An intelligent EMS energy management system

• A full range of high-reliability Far East cables

Together, these components form a highly integrated and coordinated system architecture, laying a solid foundation for safe, stable, and long-term operation.

Proven Liquid-Cooling Technology Adapted to Complex Site Conditions

Located in Wuqiang County, Hengshui City, the project site features complex geological conditions and high construction difficulty. Drawing on its experience from previous projects such as the Hebei Chunsheng Energy Storage Power Station, Far East Battery optimized both system design and construction planning to ensure high-quality delivery under challenging conditions.

The project adopts Far East Battery’s self-developed PowerSTROM 5000 liquid-cooled energy storage container, featuring high energy density, high efficiency, strong system stability, and flexible configuration.
An A/B mirrored battery compartment design, combined with a string-type PCS solution, effectively reduces inter-cluster circulating currents while improving charge/discharge efficiency and energy throughput. Each 20-foot container adopts a single-side access design and supports a multi-level fire protection architecture with integrated safety linkage systems. The intelligent thermal management system precisely controls temperature and temperature differentials, extending system life, improving operational efficiency, and reducing long-term operating costs—fully demonstrating Far East Battery’s engineering and delivery capabilities in large-scale energy storage projects.

AI-Driven Safety Operations: From Passive Response to Proactive Prevention

Compared with traditional energy storage projects, the Hongbu Energy Storage Power Station fully integrates an AI-powered safety operations system through its EMS, establishing an intelligent O&M framework centered on early safety warning and proactive risk prevention.

Based on continuous large-scale data acquisition and analysis, the system conducts comprehensive evaluations at the cell, module, and system levels, enabling early identification of sub-health conditions, pre-thermal-runaway risk characteristics, and potential station-level safety hazards. This capability fundamentally shifts operations from reactive maintenance to proactive safety management.

With minute-level, one-click active health diagnostics, potential risks can be accurately located down to the cell level, while expert-assisted maintenance recommendations significantly improve response accuracy and efficiency. Combined with a 72-hour nationwide emergency response service, the system achieves approximately 30% reduction in O&M labor costs and 65% improvement in overall operational efficiency, providing robust assurance for the safe, stable, and long-term operation of large-scale independent energy storage facilities

Enabling Market Participation and Shared Value Creation

Following commissioning, the project will participate in the power market through a diversified business model combining capacity leasing, power trading, and ancillary services. This approach enables broader sharing of energy storage resources among renewable energy developers, further enhancing renewable energy consumption. At the same time, the project supports grid peak regulation, frequency control, and market-oriented transactions, strengthening grid flexibility and security while delivering both economic and social value.

A Benchmark Practice for AI-Enabled Energy Storage

The successful grid connection of the Hebei Wuqiang Hongbu Energy Storage Power Station marks a landmark achievement for Far East Battery in building benchmark projects for AI-enabled safety operations in energy storage. It provides a scalable and replicable reference for the intelligent and safety-oriented operation of large-scale independent energy storage projects.

Looking ahead, Far East Battery will continue to drive innovation, advancing energy storage systems toward higher reliability, greater intelligence, and improved operational efficiency. By actively supporting the development of new-type power systems, the company remains committed to contributing to energy transition and global low-carbon development.
