Powering Through the Summer Heat: WHES Supports Pangang Group’s Peak Season Energy Security and Green Transformation
**As the first large-scale behind-the-meter energy storage project in Qingbaijiang District**, the 12.5 MW/25 MWh battery energy storage system at Chengdu Steel & Vanadium utilizes advanced containerized lithium iron phosphate (LFP) battery technology. Integrated with the facility's internal power network, the system provides peak shaving, load shifting, and backup power, helping optimize energy consumption while improving operational resilience.
From contract award to final commissioning and grid connection, the entire project was completed in just **57 days**. Throughout the accelerated delivery schedule, WHES's sales, engineering, and technical teams worked around the clock to ensure seamless installation, commissioning, and on-time grid connection, demonstrating the company's strong execution capabilities and commitment to project delivery.
Just one day after commissioning, State Grid Chengdu Power Supply Company requested the system to discharge electricity during the evening peak demand period (21:00–23:00). WHES OS responded immediately, successfully demonstrating the system's reliability, responsiveness, and operational flexibility under real-world grid dispatch conditions while supporting grid stability during periods of high demand.
The project's strong performance enabled an accelerated acceptance process by the local grid operator. It was subsequently recognized within Pangang Group and featured by **more than 60 industry media outlets and online publications**, establishing the project as a flagship reference for commercial and industrial battery energy storage deployments in Sichuan Province.

#### AI-Driven Energy Management: Optimizing Energy Storage for Dynamic Power Markets
As energy storage transitions into a fully market-driven era, intelligent energy management is becoming the key to maximizing project value. At the core of this transformation is WHES OS, WHES's self-developed energy management platform, designed to optimize system performance and revenue generation in increasingly dynamic electricity markets.
**The latest WHES OS 2.0 introduces AI-powered intent recognition**, enabling operators to interact with the system using natural language. Based on user objectives and real-time market conditions, its built-in AI Agent automatically generates and continuously optimizes charging and discharging strategies with rolling updates every 15 minutes.
To further enhance transparency and user confidence, WHES OS 2.0 also features strategy visualization and playback capabilities, allowing operators to review and understand every AI-generated dispatch decision. By making optimization strategies fully transparent and traceable, the platform combines the efficiency of AI-driven automation with the operational visibility required by industrial and commercial energy users.

Following the successful deployment of these flagship projects, Pangang Group is continuing to expand its energy storage portfolio across additional sites. Building on this momentum, WHES will further strengthen its presence in the steel, metallurgy, and other energy-intensive industries, delivering intelligent AI-powered energy storage solutions that help industrial customers optimize energy management, improve operational efficiency, and accelerate their digital and low-carbon transformation.
As electricity markets continue to evolve, WHES remains committed to empowering industrial enterprises with advanced battery energy storage and intelligent energy management technologies, supporting a more resilient, efficient, and sustainable energy future.
