35/110 kV “Košava” Substation

35/110 kV switchyard for Košava Wind Farm. The project was carried out in 2017-2019 in South Banat District, Uljma residential area in Vršac municipality, under investor Prime General Constructions doo Beograd.

In a village called Izbište, near Vršac within the area of South Banat, 35/110 kV “Košava” Substation was built for wind farm requirements of the investor MK Fintel Wind. The substation consists of two parts, the plant where voltage is transformed from 35 kV to 110 kV and a 110kV switchyard.

The construction of the facility was planned to be done in two phases.

In the first phase, which was completed, a transformation plant was constructed consisting of two 35/110 kV 40 MVA energy transformers and a 35 kV nine-cubicle plant. In addition, a 110 kV switchyard, consisting of five 110 kV bays: two transformer bays, two line bays and one coupler bay, was constructed, functionally tested and put into operation.

In the second phase, depending on the built wind turbines, it is envisaged to equip the 35/110 kV substation with another 40 MVA transformer. In the 110 kV switchyard, another transformer bay and line bay will be equipped with high-voltage equipment, which were left as a spare in the first phase of construction.

After the second phase, three 35/110 kV transformers with a total power of 2×40 MVA + 40 MVA will be operating.

The construction of wind farms results in generation of electricity from renewable sources, i.e. from wind energy, which makes Serbia strategically positioned as a green energy producer.

Wind power is one of the clean ways to obtain electricity, which is why it is recognized in the world as an important factor for the future of our planet. Wind is a renewable energy source, which means that, unlike fossil fuels, for example, it will not be consumed, and it does not release combustion gases during electricity generation that would increase the greenhouse effect on our planet and thus aggravate global warming.
