Choosing rooftop solar power for the saving problem
In the context of increasing energy costs and increasingly strict requirements for green development and emission reduction from international markets, many manufacturing enterprises are actively looking for energy-saving solutions, gradually switching to using clean energy. At Phuong Nam Garment & Trading Co., Ltd. (Phuong Nam Garment Company), the leadership is planning to invest in rooftop solar power to serve the lighting system for the production workshop.
Sharing with a reporter from Lao Dong Newspaper, Mr. Nguyen Van Hang - Director of Phuong Nam Garment Company said that, with the characteristics of a textile and garment manufacturing enterprise with a large electricity consumption, investing in a large-scale solar power system sufficient to meet the entire production operation is still a difficult problem due to high investment costs and complex technical requirements.
Initially, businesses choose to invest in rooftop solar power systems to serve the lighting needs in factories. This plan helps businesses gradually access clean energy, while not creating too much pressure on investment capital. In addition, it also helps businesses achieve the goal of reducing emissions, in line with the greening trend in the textile and garment industry.
According to Mr. Hang, the enterprise has worked with a number of solar power solution providers to learn about technology and appropriate implementation plans. It is expected that in the next few weeks, the unit will survey workshops, propose system designs and calculate investment efficiency.
The textile industry can save up to 30% of energy
Not only stopping at economic benefits, the use of renewable energy also helps businesses meet increasingly strict green standards from the export market. According to Dr. Nguyen Xuan Quang - Institute of Energy Technology (Hanoi University of Science and Technology), textiles and garments are one of the important industries of Vietnamese industry. According to data, this industry accounts for about 8% of the total energy consumption of the entire industry. The potential for energy saving is very significant, averaging about 20%. Many factories can even save from 10% to 30% of energy consumption when applying appropriate solutions.
Some potential solutions today are to install rooftop solar power systems. Textile and garment factories often have large roof areas, which are very favorable for deploying self-producing and self-consuming models. In addition, optimizing the air and compressed air systems also brings high efficiency, especially in textile and dyeing factories" - Dr. Nguyen Xuan Quang said.
Regarding the benefits of applying energy-saving measures, Dr. Nguyen Xuan Quang said that the clearest reflection is cost savings, because energy is the production cost. In addition, Vietnam's textile and garment products mainly serve exports and international markets are increasingly placing high requirements on the environment and social responsibility. Many businesses today have to meet environmental, social and governance (ESG) standards to be able to access and maintain the market. In that context, energy saving plays an important role in reducing greenhouse gas emissions, demonstrating the responsibility of businesses for the environment and climate change.
To promote energy saving in the textile and garment industry, Dr. Nguyen Xuan Quang believes that, first of all, it is necessary to standardize the energy management system. Next, it is necessary to focus on optimizing the steam system, the recovery of stagnant water and heat utilization can bring significant efficiency. Businesses need to approach the problem in a comprehensive direction, instead of individual solutions. When looking at the entire system, businesses will discover more savings opportunities, from electricity, compressed air to refrigeration systems.
Dr. Nguyen Xuan Quang said that currently, regulations on energy auditing have been issued and applied to key energy consuming enterprises. However, the construction of a standard energy management system has not been fully implemented.
