📋 Tender Overview
On July 1, the National Power Transmission Corporation (EVNNPT) and related units successfully energized the project of installing the second transformer of 220 kV Can Duoc substation (Tay Ninh province) and the 500 kV AT2 transformer with a capacity of 900MV under the project of installing the second 500 kV-900MVA transformer and the 220 transformer. kV-250MVA 2nd 500kV transformer station Chon Thanh, Dong Nai city. Download The second transformer of Can Duoc 220 kV TBA has just been successfully energized - Photo: NPTPMB These two projects are invested by EVNNPT, the Power Transmission Project Management Board (NPTPMB) manages the project, and Power Transmission Company 4 takes over operation. The project of installing the second transformer of Can Duoc 220 kV TBA has the scale of installing an additional transformer. 220/110/22 kV with a capacity of 250MVA (AT1) and a 110/22 kV transformer with a capacity of 63MVA. The project also expands and completes the 220 kV, 110 kV feeder system and 22 kV distribution system to improve power transmission capacity, meeting the growing load needs of the region. RELATED NEWSEVNNPT focuses on maintaining security national power transmission during peak heatwavesEVNNPT and EVNNPC coordinate to accelerate power supply projects for Bac Ninh provinceOvercoming the historic heatwave, EVNNPT maintains the vitality of power transmission in the North.Completion of energizing the project of installing the second transformer of Can Duoc 220kV substation is important in improving power supply capacity, enhancing the reliability of power grid operation in Tay Ninh province and surrounding areas; Reduce the load on existing transformer stations, meet the needs of local socio-economic development, and contribute to ensuring national energy security. Project of installing the second 500 kV-900 MVA transformer and the second 220 kV-250 MVA transformer at Chon Thanh 500 kV substation has the scale of installing an additional 500 kV AT2 transformer with a capacity of 900 MVA, increasing the capacity Capacity of 500kV Chon Thanh transformer station increased to 2x900MVA; Additional installation of 220 kV AT4 transformer with capacity of 250MVA, short-circuit current limiting resistance and many other synchronous items such as 500 kV, 220 kV, 110 kV feeders, control and protection systems, SCADA and related auxiliary equipment. Download The second transformer, 500 kV Chon Thanh substation, has just been successfully energized - Photo: NPTPMBThe project was built at the existing 500 kV Chon Thanh substation in Minh Thanh ward, Chon Thanh town, Binh Phuoc province (formerly), now Chon Thanh ward, Dong Nai province. Previously, in October 2025, NPTPMB successfully energized transformer 220 kV-250MVA. Thus, after completing the project, the 500kV Chon Thanh substation will have its capacity increased to 2,300MVA. Completion of the entire project will contribute to significantly improving the transmission capacity of the southern regions power grid, enhancing the reliability of power supply to Dong Nai city and surrounding areas; meeting the increasing load demand, serving to attract investment, develop industry, trade, services and ensure national defense and security in the area. The energization of the project on the date of EVNNPTs founding (July 1, 2008 - July 1, 2026) continues to affirm EVNNPTs core role in investing in developing the national power transmission system, and at the same time demonstrates the determination of NPTPMB and units participating in the project to Realizing the goal of building a modern, safe, reliable power transmission system, contributing to the cause of industrialization and modernization of the country.
