GSL Energy's 125kVA/261kWh Liquid-Cooled ESS Transforms Power Management at Foshan Industrial Hub

In the bustling manufacturing heart of Foshan, a prominent industrial park faced a growing challenge: how to meet rising energy demands while minimizing operational costs and environmental impact. Traditional power infrastructure was insufficient — especially during peak production hours when electricity tariffs surged. That's when GSL Energy stepped in with a forward-thinking solution.

The Challenge

The park's energy load had increased dramatically due to factory expansions and automation upgrades. Facility managers needed a stable, scalable energy storage system that could not only support peak shaving but also maintain high performance over time — even under continuous, high-load operations. Reliability, safety, and energy efficiency were non-negotiable.

The Solution: Liquid-Cooled Energy Storage System by GSL

GSL Energy deployed a 125kVA/261kWh liquid-cooled energy storage system, tailored specifically for high-demand commercial and industrial (C&I) applications. The setup includes nine modular battery cabinets, engineered for optimal space utilization and effortless future expansion.

At the heart of this system is GSL's advanced liquid cooling technology, delivering stable thermal control across all modules — a key factor in achieving consistent performance at 90% Depth of Discharge (DoD). The system boasts a high efficiency of 89%, with an integrated Power Conversion System (PCS), optional Maximum Power Point Tracking (MPPT) controllers, and static transfer switches (STS) ensuring smooth grid interaction and fast response.

Why It Works

- Plug-and-play installation minimized downtime during deployment

- True modularity enabled flexible scaling for future load growth

- IP54 protection ensures durability in industrial settings

- Smart energy software fine-tunes load profiles to maximize cost savings

- Certifications: IEC, EN, UN38.3 — guaranteeing international safety compliance

The Result

Since commissioning, the energy storage system has enabled the industrial park to significantly reduce peak energy costs and improve grid stability. Operators now enjoy extended battery life — retaining 80% capacity after 6,500 cycles, and far fewer maintenance interruptions thanks to the liquid-cooled design that mitigates overheating risks.

This project exemplifies how industrial zones can embrace energy innovation to achieve sustainability goals, improve cost efficiency, and future-proof their operations.
