Macedonian Power System 3 4 Grid facts and characteristics
Transmission system (TS) comprises of 400 kV and 110 kV transmission overhead lines and cables. Five 400/110 kV/kV substations connect the 400 kV and 110 kV networks TS is connected with the neighboring systems via 400 kV interconnections Total installed generation capacity in 2014 is 1857 MW (connected to the transmission grid), mainly shared among 580 MW of HPP-s (31%) and 1240 MW of TPP-s (67%).
Macedonian Power System 4 5 Structure of electrical power system The 400 kV transmission lines are the backbone of the transmission grid in the Republic of Macedonia. They form a 400 kV ring comprised of three transmission lines connecting the largest consumption located in the northern part of the country with the largest production facilities located in the south-western part. Also, the 400 kV transmission lines are used for interconnection to the neighboring power systems. The 110 kV transmission grid connects the large hydro power plants, all of the larger cities, as well as the industrial centers. The 400 kV and 110 kV transmission grids are coupled through five substations. A Project for reconfiguration of the 110 kV grid in the south-western part of the country is currently underway.
