The Trans-Balkan corridor is a set of elements of the electricity transmission network on 400 kV voltage level, which should allow a better mutual energy connection between Montenegro, Bosnia and Herzegovina and Serbia, but also their connection with the proximate surroundings. This cluster consists of the Project of interconnection Montenegro – Italy (new submarine cable Lastva (MNE) – Villanova (Italy), converter stations in Italy and Montenegro and SS 400/110/35 kV “Lastva“), as also project of construction and enhancement of internal 400 kV network in Montenegro, Serbia, and the construction of interconnection overhead lines 400 kV between Montenegro, Serbia and Bosnia and Herzegovina.
The Trans-Balkan corridor is aimed at improving conditions for electricity transmission from the direction of north towards the south part of the region and in that way allow further integration of the electricity market, as one of the priorities of the European energy policy.
Section of the Trans-Balkan corridor passing through Montenegro includes the following projects:
400 kV OHL “Lastva – Pljevlja“ (sections 400 OHL kV Lastva – Čevo and 400 kV OHL Čevo – Pljevlja), including also SS 400/110/35 kV „Lastva“;
400 kV OHL “Pljevlja – Bajina Bašta“ (section through Montenegro);
Supporting reconstructions and reinforcements in the system
As a part of the Trans-Balkan corridor, these projects were included in the list of projects of Pan-European importance during drafting of the ENTSO-E Ten-Year Network Development Plan (TYNDP). The corridor is a direct sequence of the project of common interest of members of the European Union (PCI lists for 2013 and 2015) – 3.19. – submarine cable Italy – Montenegro.
The entire corridor, envisaged by the ENTSO-E Ten-Year Network Development Plan (TYNDP), includes also the following projects on the territory of neighboring countries:
400 kV OHL “Višegrad – Bajina Bašta“;
400 kV OHL “Obrenovac – Bajina Bašta“ and
400 kV OHL “Kragujevac – Kraljevo“.
400 kV OHL “Pljevlja 2 - Bajina Bašta”:
Project 400 kV OHL “Pljevlja 2-Bajina Bašta“ on the territory of Montenegro includes the construction of:
- double 400 kV overhead line Pljevlja – border with Serbia, with a length of 15,7 km
- two new 400 kV overhead line bays in SS “Pljevlja 2”.
The Feasibility Study of new 400 kV interconnection between Montenegro, Serbia and Bosnia and Herzegovina has been done in the previous period, which received a positive opinion.
It has been planned to develop the overall project of regional 400 kV interconnection in two phases during which Montenegro, Serbia and Bosnia and Herzegovina shall connect through double-circuit 400 kV overhead lines. Construction of the 400 kV OHL “Pljevlja 2-Bajina Bašta“ is envisaged in the first phase.
Financing of the Trans-Balkan corridor – section of Montenegro will be performed by a combination of own funds of CGES, loan arrangements with EBRD and KfW Bank, and also funds allocated by the European Commission (grant) within the “Berlin Process” on the Western Balkans Six Summit, for whose implementation is authorized the German development bank - “Kreditanstalt für Wiederaufbau“ (KfW).
