Project Description

Even though the subprojects of the North CSE Corridor may seem geographically distant, they all represent the segments of the important route of energy transmission from Romania to the Western parts of the region, mainly Bosnia and Herzegovina, Croatia and Italy, which all could experience energy deficiency and the need for import in the years to come. On the other hand, Romania is one of the largest energy exporters in the region, and so the significance of the project will be even more emphasized after the planned integration of a large amount of RES in this country takes place. This becomes obvious if one considers the full internal 400 kV transmission system of Serbia, where it can be seen that the closest electrical connection between the S/S Belgrade West (subproject 1) and HPP Djerdap 1 (starting point of the interconnector defined in subproject 3) is direct via the new 400 kV line S/S Belgrade West – WPP Cibuk 1 (subproject 2) and the existing 400 kV lines WPP Cibuk 1 – TPP Kostolac B and TPP Kostolac B – HPP Djerdap 1.

The North CSE corridor project largely facilitates electricity transits in the region, enables market coupling and reduces the possible consequences of the abovementioned bottleneck. These goals are already well-known and established as the primary drivers of the Transbalkan corridor - Phase I. In this meaning, Project North CSE may be referred to as the initial section of the Second Phase of the Transbalkan Corridor.

North CSE Corridor project would become an integral part of the Transbalkan corridor – Phase II, aiming to solve the following problems: increased transit from the East (Romania, Bulgaria, Ukraine, Moldova) to the West (Croatia, Bosnia and Herzegovina), which is the consequence of planned RES integration in this part of the region; security of supply in the region of Belgrade, Srem and area between Belgrade and Novi Sad; energy evacuation from new production capacities (TPP Kostolac B3, as well as the integration of clean energy from HPP Djerdap 1 and wind power plants in the area between Pancevo and Zrenjanin); expected bottleneck for an outage of 400 kV OHL between TPP Kostoac B and Belgrade region.
