Supertex Textile JSC's 360 knitting machines in a 10,000-square-meter factory consume a significant amount of electricity, so they have equipped different measures to save power as much as possible.
"We have adopted various solutions, including variable frequency drives, inverter technology, and solar power systems, to save energy while limiting emissions. Despite increased production, our electricity consumption has remained stable," said Le Dai Quang, Deputy General Director of the company located in Thanh Oai Industrial Zone, Bich Hoa Commune, Thanh Oai District.
Green energy companies in Hanoi

Supertex is not alone in its efforts. A large number of other Hanoi-based companies are adopting green energy. Terumo Vietnam Medical Equipment Co., Ltd., Hanwha Aero Engines, and the LOTTE MALL West Lake Hanoi are leading examples of solar energy use.
Landmark buildings in Hanoi, such as Vietcombank and Indochina Plaza Hanoi, have installed automated energy management systems to monitor and control their electrical systems, air conditioning, and lighting.
Other companies, including Havitech and Heineken Vietnam, have integrated variable frequency drives into their production lines, pumps, and fans, resulting in significant energy savings.
Preliminary estimates show that since the campaign began, Hanoi businesses have saved nearly 134.9 kTOE (kilotons of oil equivalent), or 1.67% of projected energy consumption.
"Businesses are increasingly prioritizing energy-saving solutions, especially after the recent heat waves," Nguyen Hoang Minh, Director of IoTeamVN, told Cong Thuong Newspaper.
IoTeamVN is rolling out a green power monitoring system that enables real-time tracking and analysis of energy consumption for individual devices. These solutions allow businesses to save between 3-5% on energy costs, with a payback period of about 20 months, he added.

Over the past six years, Hanoi has instituted a program for the evaluation and recognition of facilities as users of green energy. Those who join the program receive support in establishing energy management systems and adopting advanced technologies. In 2023, 66 facilities met the certification criteria, with 19 facilities saving 9,530 TOE, amounting to VND106.7 billion (US$4.2 million) over three years.
It is expected that the facilities will save 15,860 TOE, which is equivalent to nearly VND 178.9 billion ($7.1 million) over the next five years.
Some 110 solutions have been adopted by other 22 energy-intensive businesses, saving 700.3 TOE, or VND7.6 billion ($301,359) throughout the course of the project's three years. They are expected to save 1,167 TOE, equivalent to VND13.2 billion ($523,413) in the following five years.
Le Dai Quang of Supertex Textile JSC emphasized that while some energy-saving measures require significant initial investment, companies consider it an essential expense.
He added that many export markets now impose strict standards for clean production and emissions reduction. By pursuing energy-saving solutions, companies not only save money but also gain access to demanding international markets.
According to the Hanoi Department of Industry and Trade, the agency has teamed up with relevant agencies to provide technical support to production facilities, helping them to develop energy efficiency indices and adopt advanced technologies. These efforts recognize high-performing enterprises while promoting the dissemination of effective energy-saving practices.
The city's energy conservation and efficiency program has made it possible for local businesses to reduce costs and enhance the efficiency of their operations. These initiatives benefit businesses and contribute to environmental protection and sustainable development in the city, the department said.
Hanoi is solidifying its position in the battle against climate change and creating more growth prospects for domestic companies by displaying a strong commitment to technology adoption and raising public awareness of energy saving.
