• Location: Phu Tho, Vietnam

• Implementation Time: November 2025

• System Scale: 261 kWh BESS + DC Fast Charging Station + Solar Rooftop

• Application: Supporting EV charging operations at an electric vehicle dealership

• Implementing Partner: GG Industries Joint Stock Company

2. Project Objectives

This project was implemented with the following goals:

• Ensure stable power supply for EV fast charging during peak demand periods

• Reduce electricity costs by storing energy during off-peak hours and discharging during peak time

• Increase energy independence, especially in the event of grid instability

• Real-world operation of a Smart Grid model with an EV charging station integrated with BESS and Solar. The BESS will supply power to priority loads in the event of a grid outage

3. Key Technical Specifications

4. GGI’s Solution

• The Smart Grid system is operated with BESS configured to prioritize power supply to critical loads during grid outages.

• The distributed energy storage design is optimized and integrated with the rooftop solar PV system for enhanced operational efficiency.

• Real-time monitoring via IoT platform, enabling dealership owners to track system performance and energy savings

• Installation scheduled based on dealership operations, avoiding any disruption to business activities

5. Results & Benefits

• Reduced peak load on the grid by approximately 20%

• Lowered electricity bills by an average of  100% per month

• Stabilized power supply for EV chargers, enhancing customer experience
