In response to rising electricity costs and increasing financial pressures, particularly on retail supermarket chains in Vietnam, it is crucial to identify effective energy-saving solutions for your supermarket chain. Following the insights in this article, your supermarket chain will not only save costs but also enhance operational efficiency in 2024!

Here are 5 smart energy saving solutions for your supermarket chain:

1. Energy Audit

Energy auditing is a fundamental but crucial step that cannot be overlooked. Understanding current electricity usage, analyzing consumption levels, and identifying energy-intensive sources will help us determine suitable energy conservation measures. Working with major supermarket chains in Vietnam, GreenYellow has identified three systems with high electricity consumption: refrigeration systems, Heating, Ventilation, and Air Conditioning (HVAC) systems, and lighting systems.

2. Upgrading Refrigeration Systems

One of the largest sources of energy consumption for supermarket chains is the refrigeration and freezing system. Therefore, GreenYellow recommends upgrading refrigeration equipment to optimize efficiency and reduce electricity consumption. By using equipment with new technology, the refrigeration system will achieve higher efficiency, ensuring energy cost savings and contributing to environmental protection.
Recently, GreenYellow carried out a Refrigeration Upgrade project for Bac Lieu Seafood Joint Stock Company, including replacing refrigeration compressorselectrical cables, and some poorly performing equipment. This upgrade project helped the client address energy saving solutionenergy-saving challenges, reducing electricity consumption by approximately 1MWh and reducing CO2.

3. HVAC Retrofit

Heating, Ventilation, and Air Conditioning (HVAC) systems play a crucial role in maintaining comfortable air conditions within supermarkets. Improving HVAC systems by replacing equipment, using smart, advanced devices to regulate temperature, and ensuring energy-efficient working environments will significantly reduce energy consumption and optimize operations.
In an Energy Efficiency project with the Mega Market supermarket chain, GreenYellow improved the HVAC system by replacing Condensing Units (CDUs) and Air Handling Units (AHUs). The new CDUs operate with more efficient components, allowing the system to achieve equivalent performance with lower energy consumption, thereby achieving significant energy cost savings.

4. Lighting Systems Replacement

When designing lighting systems for large spaces such as supermarkets, besides designing suitable lighting for each merchandise area, we need to pay attention to energy-saving and lighting efficiency. GreenYellow proposes retrofitting lighting systems with LED lights to reduce electricity consumption, maintenance costs, and be environmentally friendly. According to the National Program for Energy Efficiency, after replacing all fluorescent lights with LED lights, Mega Market Thang Long supermarket reduce electricity consumption by 38%.

5. Implementing Energy Management Systems

Finally, to ensure continuous energy efficiency and savings, supermarket chains should invest in energy management systemsThrough energy management, you gain a better understanding of electricity consumption levels at your facilities in real-time, helping to identify electrical issues early, thereby reducing operational costs and improving electricity usage efficiency.
