ENTECH HANOI 2025 contributes to the development of markets for high-performance, energy-efficient technologies and equipment, reduces environmental pollution, and promotes progress in the energy and environmental sectors.

Speaking at the opening ceremony, Mr. Vo Nguyen Phong, Member of the Hanoi Party Committee and Director of the Hanoi Department of Industry and Trade, stated: "The city has directed the Department of Industry and Trade to lead, in coordination with relevant departments, agencies, and local governments, the implementation of electricity and energy-saving measures in accordance with Decision No. 280/QĐ-TTg dated March 13, 2019 and Directive No. 20/CT-TTg dated June 8, 2023 of the Prime Minister. The goal is to maximize investment resources, improve the city’s power grid to meet electricity demand growth of 7.1%, reduce energy loss to below 3.6%, and save 2.2% of total power consumption—particularly ensuring a minimum 5% electricity saving for all government agencies, organizations, and enterprises—thereby ensuring a stable electricity supply for the city."

ENTECH HANOI 2025 is held under the patronage of the Ministry of Industry and Trade, the Ministry of Science and Technology, the Vietnam Energy Conservation and Energy Efficiency Association, the Korean Ministry of Environment, and the City of Busan, Korea.

These activities offer a platform for enterprises to showcase technologies and products, and enable government and city agency experts to explore cutting-edge global energy storage technologies.

The fair includes a three-day product showcase by participating companies. These activities aim to increase outreach, inform policy development in energy and environmental technology, and elevate the role of the energy and environmental technology sector in contributing to sustainable socio-economic growth. The event also fosters international cooperation in research and technology development, facilitates technology transfer, attracts foreign capital, and supports enterprises through business networking, information exchange, investment promotion, and access to advanced energy-saving and pollution-reducing technologies.
