In 2018, AD MEPSO, the North Macedonian TSO, awarded us the modernization project of the 400 kV Skopje 4 TS, a crucial hub in the power grid of the Republic of North Macedonia.

The project included the revitalization of primary equipment at 400 kV and 110 kV fields, installation of secondary equipment for protection and control, implementation of SCADA system, along with design, electrical assembly, construction works, equipment testing, and commissioning.

Skopje 4 TS was the first 400 kV substation in North Macedonia, and this modernization project represented its most significant reconstruction since it was built in 1978.

The modernization of Skopje 4 TS was carried out within the energy industry development project aimed at connecting the Macedonian and Albanian power systems, financed by the European Bank for Reconstruction and Development.
