1 Operational Challenges in Industrial Manufacturing Environments

Honda Vietnam Factory in Ha Nam is a large-scale production facility, requiring a highly reliable and continuous cooling system to maintain a stable production environment, especially in areas requiring strict temperature control.

Biggest challenge:

1. High Energy Costs: Operating a large capacity Chiller system for long production hours during peak hours significantly increases electricity costs.

2. Durability requirements: The solution needs to be able to withstand harsh operating conditions in industrial environments and outdoor weather.

3. Limited space in the plant: Need an energy storage solution that can be deployed in outdoor areas efficiently and safely.

2 Specialized Solution From ESS Vietnam: Above Ground Concrete Tank

ESS Vietnam has provided and deployed a reinforced concrete Cold Storage Tank (TES) solution placed outside the construction, specifically designed for Honda Vietnam's industrial environment:

• Efficient Storage: The system takes advantage of low electricity prices during off-peak or peak hours to produce and store 4,800 kWh of cooling capacity .

• Reduced Production Load: This reserve cold is used to supply the air conditioning system and cool production areas during peak daytime hours, helping the Chiller system reduce load, minimizing expensive electricity costs.

• Above Ground Concrete Tanks: This solution utilizes the space outside the factory and ensures superior structural durability, resistant to environmental impacts.

3 Financial Performance and Implementation Process

The Honda Vietnam project in Ha Nam affirms the feasibility of the TES solution in optimizing operating costs for industrial manufacturing enterprises.

• Clear Investment Return: With the ability to save on peak hour electricity costs, the project achieves a payback period (ROI) of 4 years , a competitive index in the field of industrial infrastructure investment.

• Automatic Operation: The system is controlled by an intelligent control cabinet, ensuring the charging/discharging process takes place automatically and optimally.

• Implementation Time: The project was completed, installed and officially put into operation in April 2016 .

3.1 System Deployment and Monitoring

The installation process is carried out carefully and professionally, with attention to durability and automatic operation:

1. Cold tank at Honda Ha Nam factory: Completed structure of exposed reinforced concrete tank, harmoniously integrated with the overall industrial architecture of the factory.

2. Control cabinet: Install a central control cabinet, which manages the entire operation process of the TES system, from charging, discharging to performance monitoring, ensuring stability and high automation.
