EMS plans to invest 50-70 million euros in the next 5-7 years. The funds will be invested for development of transmission grid, where the main projects will be replacement of 220 kV power lines with 400 kV lines in western part of Serbia. The cost of this project is estimated at 61 million euros. The most important part of this project will be replacement of power lines between pump storage hydropower plant Bajina Basta and 400 kV substation in Obrenovac.
The feasibility study for this project is under way, and the project should be completed by 2015. EMS said that this project might be funded by European Bank for Reconstruction and Development (EBRD) and Ger- man KfW Bank.
Among other project, EMS is currently involved in construction of 400/100 kV substation in Vranje. Overall cost of the project is 19 million euros, where EU will donate 15.5 million euros, and the rest of the funds will be provided by EMS. The construction of Vranje substation was preceded by the construction of 400 kV interconnection power line from Nis toward Macedonian border, which was prerequisite for construction of Vranje substation and further enlargement of Leskovac substation (upgraded from 220 kV up to 400 kV volt-
5.3.1 Ongoing projects
Serbia – Macedonia (Nis – Stip)
We characterize this project as on-going, since only Serbian section of the power line is completed. EMS has finished works on its section of the power line on 8th of December 2011. Serbian part of the interconnection is 140 km long, where first section Nis – Leskovac is 40.5 km long and second section, Leskovac – Macedoi- nan border, is 100 km long. European agency for reconstruction (EAR) and EMS funded this project. Overall cost of the Serbian part of the interconnection is 31 million EUR, where 27 million EUR was donated from EAR, and remaining funds were provided by EMS alone. When completed, Serbia – Macedonia NTC will be increased for sam 250 MW.
The construction works have lasted for three and a half years. The power line has OPGW cables, which cre- ated telecommunication network for this part of the country. The construction works were carried out by local companies Energoprojekt, ABS Minel and Energomontaza. The project has also created conditions for further enlargement of 400 kV Leskovac substation (upgraded from 220 kV) and construction of new 400 kV substation Vranje 4.
The project is supported by EU. The power line will be important for transmission in Southeastern Europe, especially for increasing imports of Greece, but will also strengthen local electricity grid
In December 2012, EMS has put in service the section of the 400 kV interconnection power line between Leskovac and Macedonian border. The section of the power line between Leskovac and Macedonian border will be in no-load operation, due to fact that Macedonia still did not complete its section of the interconnec- tion power line. Nevertheless, the power line in no-load operation is expected to improve voltages in this part of the country, EMS said.
5.3.2 Recently finished project
Serbia – Bosnia and Herzegovina (Ugljevik – Sremska Mitrovica)
In April 2006, new 400 kV line between Thermal Power Plant Ugljevik in Bosnia and Herzegovina and Srem- ska Mitrovica in Serbia was put in operation. This power line is contributing with significant relaxation of 400 kV line. Ernestivnovo (Croatia) - Sremska Mitrovica (Serbia). Average achieved power flow on new line is around 170 MW in direction to Bosnia and Herzegovina.
5.3.3 Announced projects
Serbia – Romania (Pancevo – Resita)
EMS also plans to build new 400 kV interconnection power line toward Romania, from Pancevo (Serbia) to Resica (Romania). This particular power line will be important for construction of wind farms in Vojvodina
province. The justifiability study, general design as well as environmental impact study for this project was completed, and the exact 80 km route of the power line on Serbian soil was set.
In the beginning of June 2014, state-owned electricity transmission system operator Transelectrica (TEL) and EMS signed the contract for construction of 400 kV overhead power line Resita -Pancevo. The funding of the project was not secured yet.
The new interconnection line between Romania and Serbia will have double circuits. It will be 131 km long, where 63 km will be on Romanian soil. The cost of the project is estimated at 18.5 million euros and the power line should be put in service during 2015. Romania and Serbia have signed memorandum of under- standing regarding this project in 2005.In July 2011, EMS and Transelectrica agreed to speed up construction of the future interconnection. Both companies gave the priority status to this project.
The new power line is expected to increase electricity trade with Serbia and with the Western Europe and it should help the transport of electricity from wind farms and hydropower plants in the area of Portile de Fier and Resita.
Serbia – Various projects
In March 2009, Serbia and Italy have signed a Protocol on cooperation in energy sector. The protocol envis- ages joint investments in Serbian electricity grid, where main priorities would be construction of new 400kV links toward Romania, Macedonia and Montenegro. Strengthening of the grid is necessary due to undersea cable which will be built between Montenegro and Italy.
Serbia – Montenegro (Bajina Basta – Pljevlja)
The draft feasibility study for this project is initiated, but the route has not yet been set. EMS hopes that projects for new interconnection power lines will be able to attract EU funding. This project is part of the Trans-Balkan corridor, which includes the transmission power lines between Obrenovac and Bajina Basta and toward Montenegro and Bosnia and Herzegovina.
