1 Energy Challenges in the Manufacturing Industry
Cuu Long Fruit Garden Factory (in Can Tho), operating in the processing sector, requires a stable and efficient refrigeration system to preserve products and maintain the production environment. With the need for continuous cooling, the electricity cost of operating the Chiller system during peak hours is a big financial burden.
Project objectives:
-
Provide stable and reliable cold source for production process.
-
Apply energy saving solutions that have a quick payback.
-
Deploy TES systems in outdoor locations safely and sustainably.
2 ESS Vietnam's Outdoor Cold Storage Tank Solutions
ESS Vietnam deployed an outdoor Cold Storage Tank (TES) solution with a capacity of 1,500 kWh , designed to seamlessly integrate with the plant's existing infrastructure.
-
Smart Energy Storage: The TES system utilizes cheap electricity (off-peak hours) to store 1,500 kWh of cooling capacity .
-
Peak Hour Support: This reserve cooling capacity is used to reduce the load on the main Chiller system during peak hours, helping Cuu Long Fruit Garden Factory significantly reduce electricity costs.
-
Flexible Location: Outdoor tank placement makes efficient use of space, while the concrete tank structure ensures the durability required for industrial operating conditions.
3 Investment Efficiency and Implementation Process
This project demonstrates the ability of TES to effectively address energy cost issues even with moderate refrigeration capacities in the processing industry.
-
Economic Efficiency: The solution delivers clear cost savings, resulting in a payback period (ROI) of 4 years , a stable and reliable financial result.
-
Delivery Time: The project was completed and installed in September 2018 , ensuring timely completion of the factory's need to optimize operations.
