1 Energy Challenges in the Commercial Center

As a large shopping mall, Big C Ha Long faces a difficult problem regarding the cost of operating the central air conditioning system (HVAC). High electricity usage during peak hours is the main reason for high electricity bills.

The need was to find a technical solution that could balance the need for continuous cooling with the goal of saving energy costs , while ensuring a quick return on investment.

2 In-depth Solutions from ESS Vietnam

ESS Vietnam has deployed a pioneering Cold Storage Tank (TES) solution , taking full advantage of the difference in electricity prices between time frames.

1. Generation and Storage: The system uses grid electricity during off-peak hours (Off-peak, cheap) to cool and store a large amount of cold energy in the TES Tank.

2. Peak-Hour Supply: The stored cold will be released to cool the entire building during peak-hour, helping the main air conditioning system (Chiller) to reduce load or stop working.

3. Space Optimization: The TES tank is designed and installed effectively in the basement of the shopping mall, without affecting the business space and operations of the building.

3 Economic and Technical Efficiency

Big C Ha Long project has clearly demonstrated outstanding financial and technical efficiency:

• Cost Optimization: With a large cold storage capacity of 13,000 kWh , the solution helps Big C Ha Long significantly reduce expensive electricity consumption during peak hours.

• Fast Payback: The actual payback period of only 3.5 years is a clear demonstration of the high economic efficiency and profitability of the TES solution provided by ESS Vietnam.

• Sustainable Operation: The solution contributes to reducing pressure on the national grid, increasing the lifespan of the refrigeration system and is an important step towards green building standards.

ESS Vietnam is proud to be a pioneer in designing, supplying and installing Cold Storage Tanks in Vietnam, providing sustainable energy saving solutions with a team of engineers with more than 30 years of experience.
