1 Energy Efficiency Challenges and Requirements
Canon Tien Son Factory, a key production facility of the group, requires a highly reliable cooling system to maintain the rigorous electronics manufacturing process. Operating a large Chiller system during peak production hours significantly increases operating costs.
Project objectives:
-
Provides additional, stable cooling capacity to the production environment.
-
Implement strategies to effectively cut electricity costs during peak hours.
-
Install sustainable solutions in outdoor areas, in accordance with industry standards.
2 Large Capacity Outdoor Cold Storage Tank Solution
ESS Vietnam has deployed an outdoor reinforced concrete Cold Storage Tank (TES) solution with a capacity of 8,000 kWh , designed to withstand industrial and weather conditions:
-
Optimizing Electricity Costs: The system takes advantage of low electricity price periods to store 8,000 kWh of cooling capacity . This capacity is used to reduce the load or replace the operation of the main Chiller during peak hours.
-
Production Assurance: Cold storage helps maintain stable production temperatures, eliminating the risk of interruption due to lack of cooling capacity during peak hours.
-
Industrial Durability: The above ground concrete tank construction ensures long design life and easy integration into the plant Utilities system.
3 Investment Efficiency and Implementation Results
The Canon Tien Son project is a typical example showing that TES is a strategic investment, bringing sustainable financial benefits and improving operational efficiency.
-
Reliable Financial Performance: The ability to save on electricity costs during peak hours helps the project achieve a payback period (ROI) of 4 years , in line with long-term industrial investment expectations.
-
Delivery Time: The project was completed, installed and put into operation in February 2019 , ensuring continuity in the factory's operations.
3.1 Sustainable System Installation Process
Installation is carried out to a high standard, with a focus on durability and operational accessibility:
-
