Serbia’s TSO EMS inks contract for Obrenovac – Bajina Bašta power line within Trans-Balkan Corridor

Serbia’s transmission system operator Elektromreža Srbije signed a contract for the construction of a two-system 400 kV transmission line from the Obrenovac substation to the Bajina Bašta substation.

The power line from the Obrenovac substation to the Bajina Bašta substation is part of the third section of the Trans-Balkan Corridor for the transmission of electricity, a project of national and regional significance, TSO Elektromreža Srbija (EMS) said.

The Trans-Balkan Corridor connects Romania, Serbia, Bosnia and Herzegovina, Montenegro and Italy.

Apart from the transmission line, the third section comprises equipping two switchyards in the Obrenovac substation and upgrading the Bajina Bašta substation to 400 kV.

The job was awarded to Kodar Energomotaža at an international tender

The transmission line will be 109 kilometers long. The start of construction is planned for April, while the completion is expected in 2027.

The project is financed by EMS, a donation from the Western Balkans Investment Framework (WBIF), and a loan from Germany’s KfW Development Bank.

The EUR 71 million contract was signed by EMS CEO Jelena Matejić and Mladen Žujković, the representative of Kodar Energomontaža, the contractor. The company was selected after a complex international tender, according to Serbia’s TSO.

The first section of the Trans-Balkan Corridor, from Pančevo to the Romanian border, was completed and put online in December 2017.

The second section was finished in June 2022. It consisted of transmission lines between Kragujevac and Kraljevo and upgrading the substations in the two cities.

Matejić: Serbia is a crucial electricity hub in this part of Europe

The corridor plan also has a fourth section. It envisages a double 400 kV power line between the substations in Bajina Bašta in Serbia, Višegrad in Bosnia and Herzegovina and Pljevlja in Montenegro.

“The Trans-Balkan electricity transmission corridor is certainly one of the most important infrastructure projects to safeguard a stable supply of electricity in our country. It will also enable the integration of the electricity market and position Serbia as a crucial electricity hub in this part of Europe,” Matejić stressed.

The importance of the Trans-Balkan Corridor was demonstrated recently by the commissioning of the second system within the transmission link between Romania and Serbia. It increased the cross-border transmission capacity by 80% – from 500 MW to 900 MW.

Montenegro’s DSO CEDIS secures funds for grid digitalization

Montenegrin distribution system operator (DSO) CEDIS has secured funds for the installation of an advanced grid management system and procurement of smart meters.

The EUR 40 million package consists of a EUR 35 million loan provided by the European Bank for Reconstruction and Development (EBRD) and a EUR 5 million grant under the European Union’s Western Balkans Investment Framework (WBIF).

The funds are intended for a new supervisory control and data acquisition (SCADA) system and an advanced distribution management system (ADMS), as well as the procurement of new smart meters.

Smart meters help users and utility companies monitor and manage electricity usage more efficiently

The project is expected to reduce technical losses by 10%, decrease grid outages to approximately one sixth of the current level, allow new renewable energy sources to be integrated into the grid and enhance cyber security, according to CEDIS and EBRD.

The SCADA system will be used to monitor and control medium-voltage grid networks in real time. ADMS is an advanced platform that optimizes the management and operation of the electricity distribution system.

Smart meters help users and utility companies monitor and manage electricity usage more efficiently, reducing losses and improving reliability, the update reads.

The loan agreement was signed by the EBRD’s Head of Montenegro Remon Zakaria, CEDIS CEO Vladimir Ivanović, and Ivan Bulatović, CEO of EPCG.

Ivanović: The integration of smart meters will empower consumers to better understand and optimize their energy usage

According to Zakaria, the project represents a transformative step towards the digitalisation of the electricity distribution system in Montenegro.

Citizens will experience a more reliable electricity supply, and CEDIS will achieve substantial reductions in technical losses and gain the advanced capabilities required to swiftly detect and address technical faults, he added.

Vladimir Ivanović said SCADA and ADMS would revolutionize the way the company operates the distribution network. The integration of smart meters will empower consumers to better understand and optimize their energy usage, contributing to greater energy efficiency across the network, he stressed.

Last year Ivanović said CEDIS has reduced grid losses from 12.93% to 10.84% and that it planned to lower them below 10% by the end of December.
