After the installation of the second transformer is completed, the total capacity of the Nam Cam 220kV Substation will reach 500 MVA, doubling its previous capacity.

This is a Class I, Group C energy work with EVNNPT as the investor and PTC1 assigned to manage and operate the project. The project is being implemented on the reserved land area of the Nam Cam 220kV Substation in Nghi Loc Commune, Nghe An Province.

The project involves the installation of one 220/110/22kV-250MVA transformer; on the 220kV side, equipment will be installed for one 220kV main bay of the new transformer; on the 110kV side, equipment will be installed for one 110kV main bay of the new transformer; and related technical solutions will be completed to suit the new scale of the substation.

Upon completion, the project will contribute to strengthening power supply for loads in Nghe An Province and the northern region; meeting the N-1 criterion; improving the reliability and safety of power supply for the regional grid; and sharing the load with the Do Luong and Vinh 220kV substations.

According to Power Transmission Company No. 1, before the installation of the second transformer, the existing transformer at the Nam Cam 220kV Substation frequently operated at full load and was occasionally overloaded, posing potential risks to power supply reliability.

The successful energization of the second transformer at the Nam Cam 220kV Substation not only improves the substation’s operational capacity but also significantly enhances power supply for the North during heatwaves, when electricity demand continuously peaks.
