Accordingly, on the morning of April 25th in Can Tho City, EVNSPC Vice President Bui Quoc Hoan directly supervised the energization of the Co Do 110kV Substation work. The work has a total investment of over VND 237 billion and includes the following construction scale: a substation with a capacity of 2x40MVA, initially operating at 1x40MVA; and a newly constructed 110kV connecting line with 2 circuits, a length of 14.499 km, and 58 steel pole locations.

The Co Do 110kV substation is equipped with modern systems and equipment, including control, protection, SCADA, lightning protection, fire prevention and suppression, surveillance cameras, and communication systems, all in accordance with the standards of new-generation substations.

Once commissioned, the work will meet electricity demand in Co Do commune and surrounding areas, helping reduce the service radius of the 22kV distribution network, minimize power losses, and improve voltage quality. The work also improves operational flexibility and supports compliance with the N-1 criterion through load transfer capability among 110kV substations such as Thot Not, Vinh Thanh, and Thoi Lai, thereby contributing to the completion of power grid infrastructure under Can Tho City’s power development plan.

In Tay Ninh province, on April 24, EVNSPC successfully energized the Tan Tru 110kV Substation and the connecting 110kV transmission line. With a total investment of over VND 190 billion, the work includes a 110kV substation with an installed capacity of 2 x 63 MVA and a 7.62-km double-circuit transmission line connecting the Can Duoc 2 220kV Substation and the Tan Tru 110kV Substation.

 In the first phase, the work is equipped with one 63 MVA transformer and supporting infrastructure, ready for the installation of a second transformer when regional demand increases. The  Tan Tru 110kV substation is built as a digital substation, integrating modern control, protection, measurement, SCADA systems, and auxiliary items, serving both local and remote control. The project is of great significance in supplementing the 110kV power supply for the area, creating room for load growth, improving the quality of electricity services, and better meeting the residential, production, and business needs of local people and enterprises.

Meanwhile, in An Giang Province, two 110kV grid works were successfully energized within less than a week, contributing to improved power supply capacity in the area.

The work to renovate the An Bien 110kV Substation (increasing capacity from 1x40MVA to 2x40MVA) was also completed and energized on April 22, 2026. With a total investment of nearly VND 67 billion, the work includes the installation of an additional 40MVA transformer, renovation of the 110kV T1 – 40MVA transformer bay, and completion of the 110kV sectional bay.

When put into operation, the work not only solves the overload situation of the An Bien 110kV Substation, but also increases the 22kV power grid connection capacity between the Minh Phong and U Minh Thuong 110kV Substations, meeting mutual support during equipment maintenance and servicing activities; improving the N-1 operational reliability, and increasing the power supply capacity to serve the socio-economic development needs in the area.

The Vinh Quang 110kV Substation renovation work (installing the second transformer) was also successfully energized on April 21st. With a total investment of approximately VND 31.6 billion, the project expanded the substation capacity from 1x40MVA to 2x40MVA, helping eliminate overloading at the Vinh Quang 110kV Substation and easing the load on the Rach Gia and Hon Dat 110kV substations. At the same time, improving the reliability of N-1 operation, reducing power losses, and enhance the power supply capacity to serve the socio-economic development needs of Rach Gia ward, Vinh Thong ward, and neighboring areas.

Phu Thuan – Binh Dai 110kV transmission line project in Vinh Long Province officially entered operation following energization on April 22, 2026.

In Vinh Long province, also on April 25, EVNSPC successfully energized Phase 1 from the existing pole 13 to pole 22, a length of 2.5km, of the 110kV power line work from the Vinh Long 3 220kV substation (transiting to the Phuoc Hoa - Binh Minh 110kV power line). Upon completion, the work will enhance operational flexibility and strengthen the reliability of power supply to 110kV substations in the area. The work establishes a 110kV looped connection among the Vinh Long 2 220kV, Vinh Long 3 220kV, Tra Vinh 2, and Sa Dec 2 substations, helping enhance operational flexibility. The work also improves power supply reliability, increases 110kV power supply capacity, and supports the socio-economic development needs of Vinh Long Province.

Also in Vinh Long province, the Phu Thuan – Binh Dai 110kV transmission line work, with a total investment of over VND 143 billion, has been commissioned. The project comprises the construction of a 22.7km double-circuit 110kV transmission line, the expansion of one bay at the Binh Dai 110kV Substation, and the construction of two new bays at the Phu Thuan 110kV Substation.

When operational, the work will create a loop connecting the Giao Long, Phu Thuan, Binh Dai, Ba Tri, and Giong Trom 110kV substations, ensuring timely, safe, and stable power supply according to the N-1 standard; simultaneously transmitting power from future wind power plants into the grid such as Thua Duc 1, Thua Duc 2, Thanh Phong, Thanh Hai, and An Thuy; improving the reliability of power supply in the area and reducing power losses.
