EVNNPT Successfully Completes Two Major Substation Capacity Enhancement Projects in Tay Ninh and Dong Nai
In the early hours of June 17, 2026, the National Power Transmission Corporation (EVNNPT) successfully collaborated with relevant units to complete and energize two critical projects aimed at enhancing substation capacity in Tay Ninh and Dong Nai provinces. These achievements contribute significantly to ensuring energy security and promoting socio-economic development in the Southern region of Vietnam.
Project Details and Implementation
Capacity Enhancement Project at 220kV Can Duoc Substation, Tay Ninh
This project involved the installation of a second transformer at the 220kV Can Duoc Substation in Tay Ninh Province. The implementation was necessitated by the increasing electricity demand in Tay Ninh and neighboring provinces, particularly against the backdrop of socio-economic development and investment attraction in the region.
The new transformer boasts a capacity of 250 MVA and is equipped with modern protection and automation systems, ensuring high reliability and stable operation. The addition of this second transformer increases the total substation capacity to 500 MVA, doubling the original designed capacity.
Capacity Enhancement Project at 500kV Dong Nai Substation
Concurrently, EVNNPT successfully completed and energized the installation of a 900 MVA 500kV AT2 transformer at the 500kV Dong Nai Substation. This project represents one of the key initiatives under the national power transmission system development program for the 2021-2025 period.
The 500kV AT2 transformer, with a capacity of 900 MVA, incorporates the world's most advanced technology, enhancing the power transmission capability from the Southeastern region to Ho Chi Minh City and other southern provinces. The project was implemented with a total investment of over 500 billion VND, utilizing preferential loans from the Japan Bank for International Cooperation (JBIC).
Significance and Impact of the Projects
The successful commissioning of these two projects holds particular importance for the national power system, contributing to:
- Ensuring energy security for the Southern region, especially during the 2026 dry season
- Reducing the load on existing transmission lines and minimizing overload risks
- Enhancing interregional connectivity, creating favorable conditions for socio-economic development
- Meeting the growing electricity demand from industrial, service, and residential sectors
- Supporting Vietnam's commitments to energy transition and sustainable development
Implementation Process and Participating Units
Both projects were implemented under the direct supervision of EVNNPT, with the Project Management Board for Transmission Power in Southern Vietnam (NPTPMB) coordinating with various units:
- National System Market Operation Company (NSMO)
- Southern System Operation Center (SSO)
- Southern Power Transmission Company
- Tay Ninh Power Company and Dong Nai Power Company
- Construction contractors, design consultants, and equipment suppliers
The implementation process encountered numerous challenges, including adverse weather conditions, pandemic-related disruptions, and tight scheduling pressures. However, through decisive leadership and seamless coordination among all units, both projects were completed on schedule.

Future Development Plans
According to EVNNPT's plans for the 2026-2030 period, the corporation will continue implementing substation capacity enhancement projects in key areas, particularly in southern provinces. Notable upcoming projects include:
- Capacity enhancement at 500kV Phuoc Thien Substation (Binh Duong Province)
- Construction of new 500kV Tan Uyen Substation (Binh Duong Province)
- Capacity enhancement at 220kV Ben Cat Substation (Binh Duong Province)
- Capacity enhancement at 220kV Thu Duc Substation (Ho Chi Minh City)
Conclusion
The completion and commissioning of the two substation capacity enhancement projects in Tay Ninh and Dong Nai mark a significant achievement for Vietnam's power sector, demonstrating EVNNPT's determination and capability in developing a modern, reliable, and efficient power transmission system. These projects not only contribute to national energy security but also establish a solid foundation for the socio-economic development of the Southern region in the coming years.
The National Power Transmission Corporation (EVNNPT) remains committed to continuing its efforts and maintaining close coordination with relevant units to successfully accomplish all assigned tasks, thereby contributing to the sustainable development of Vietnam's power industry.
