The Ionian Adriatic Pipeline is foreseen to run from Albania (Fier), where it will connect with the Trans Adriatic Pipeline (whose implementation is also one of the prerequisites for IAP’s implementation) through Montenegro to Croatia (Ploče) with a connection to Bosnia and Herzegovina. IAP will have a diametre of 800mm and a pressure of 75 bar with reverse flow capability. The objectives of the IAP project are to: \\ ensure the possibility of gas supply from the Caspian and central-eastern sources to the western Balkan markets, enabling easier gasification of Albania, creating the preconditions for gasification of Montenegro, and completing the gasification of South Croatia and a significant part of Bosnia and Herzegovina, thus promoting economic development in the western Balkans, \\ diversify natural gas supply, provide access to Albanian and Croatian storage capacities, \\ integrate the western Balkans gas market into the European gas market, \\ promote economic development in this region. This is a multi-stage project aiming at creating a corridor that will ensure gas trans- mission between the cross-border interconnection points Bulgaria-Romania, Romania-Hungary and Hungary-Austria. It will create the necessary conditions for bidirectional gas transmission between the Southern Corridor and Central Eastern Europe ensuring the increase of the interconnection at European level. The following projects are involved in each stage of development: Stage I. for 1.75Bcm/a: \\ TRA-F-029: BG-RO Interconnection \\ TRA-N-358-stage I: Development of the NTS in RO territory, stage I \\ TRA-N-286: Reverse flow capacity at RO-HU border, stage I Stage II. for 4.4Bcm/a: \\ TRA-N-358-stage II: Development of the NTS in RO territory, stage II \\ TRA-N-377: Reverse flow capacity at RO-HU border, stage II Bulgaria – Romania – Hungary – Austria transmission corridor, project.
Stage III. for 8.8–12Bcm/a: \\ TRA-N-139: interconnection of the National Transmission System with the Distribution System and reverse flow at Isaccea \\ TRA-N-959: BRUA phase III \\ TRA-N-380: BRUA transmission Corridor At the same time, together with the project Development on the Romanian territory of the Southern gas transmission Corridor (TRA-N-362) and new NTS development for taking over new gas from the Black Sea shore (TRA-N-964), the above mentioned projects contribute to the diversity of gas supply sources as well as to the increase of security of supply by taking over the recently discovered Black Sea gas.
