1 Energy Management Challenges at Big C Quy Nhon

As a major shopping and service destination in Quy Nhon, Big C must maintain a cool, comfortable environment for customers and a stable environment for the preservation of goods. The biggest challenge lies in controlling electricity costs due to the continuous operation of the refrigeration system, especially during peak hours when electricity prices increase.

Big C Quy Nhon investor is looking for a sustainable technical solution that can effectively cut operating costs without affecting cooling performance, while optimizing construction space.

2 Underground Cold Storage Tank (TES) Solution

ESS Vietnam has deployed the Cold Storage Tank (TES) solution , an advanced thermal energy storage technology, specifically designed to meet the needs of Big C Quy Nhon:

1. Active Saving: The system takes full advantage of low electricity prices, producing and storing a significant amount of cold at night.

2. Peak Supply: During the day, the stored 13,500 kWh of cold will be used to supply the air conditioning system, avoiding the main chiller running at high capacity during the most expensive electricity hours.

3. Space Optimization: TES tank is designed to be installed completely underground in the basement parking area , freeing up valuable floor space for commercial and service purposes.

3 Commitment to Efficiency and Payback Time

Big C Quy Nhon project is a testament to the success of the TES solution in bringing clear and quick economic efficiency to the retail industry.

• High Financial Efficiency: With precise technical calculations, the project achieves a payback period of only 3.5 years , confirming the outstanding level of electricity cost savings and investment feasibility.

• Stable Capacity: 13,500 kWh cooling capacity ensures stable cooling supply, helping the Chiller system operate in optimal condition, prolonging the life of the equipment.

• On-Time Delivery: The project was completed and handed over for installation in March 2014 , demonstrating ESS Vietnam's commitment to progress and quality.

ESS Vietnam is proud to accompany large commercial projects, providing smart energy storage solutions to optimize operating costs, towards the development of green and sustainable buildings.
