1 Challenges and Goals at Big C Nha Trang

In the context of increasing electricity costs, especially at high-frequency shopping malls such as Big C Nha Trang, controlling cooling costs during peak hours is a top priority.

The main objective of the project is to implement an efficient energy storage system that not only helps to cut electricity costs but is also flexible in installation, making the most of the available space in the underground parking area.

2 ESS Vietnam's Floating Cold Storage Tank Solution

ESS Vietnam has supplied and installed the Cold Storage Tank (TES) solution , focusing on optimizing energy efficiency and adapting to the specific space conditions of Big C Nha Trang:

1. Energy Transfer: The TES system operates on the principle of charging the cold during off-peak hours when electricity prices are cheap, then releasing the cold to supply the air conditioning system during peak hours.

2. Stable Capacity: The cold storage tank provides a capacity of 13,400 kWh , ensuring a stable and continuous cold source, significantly reducing the load on the main Chiller system during the day.

3. Flexible Above Ground Installation: The highlight of the project is the installation of an above ground TES tank in the underground parking area . This solution demonstrates the flexibility in design of ESS Vietnam, ensuring quick installation, easy maintenance while still optimizing the usable space.

3 Investment Efficiency and Project Technique

The project at Big C Nha Trang is a testament to the proven economic performance of the Cold Storage Tank solution.

• Clear Economic Benefits: TES solution helps optimize electricity costs, bringing great financial benefits with a payback period (ROI) of only 3.5 years . This is an attractive index, ensuring a quick return on investment.

• Project Quality: The project was handed over and installed in October 2014 , strictly adhering to the construction progress and quality according to European standards that ESS Vietnam committed to.

ESS Vietnam is always ready to advise and design the most suitable energy storage solutions for the space conditions and cost-saving goals of every project, whether underground or above ground.
