836 kWh BESS at a Mechanical Factory in Phu Tho

In the context of rising industrial electricity costs and increasingly strict ESG requirements, a mechanical manufacturing factory in Phu Tho, Vietnam chose GG Industries (GGI) to implement an 836 kWh Battery Energy Storage System (BESS) in August 2025.

Challenges

  • High electricity costs during peak hours

  • Peak load demand charges significantly increasing operating expenses

  • Requirement to optimize the ROI of the existing solar PV system

GGI’s Solution

GGI designed and installed a BESS 836 kWh – 250 kW system, integrated with an intelligent Energy Management System (EMS) and dual liquid-cooling technology. The system complies with leading international standards: GB/T36276, IEC62477, IEC61000, and UN 38.3.
