The natural gas transmission started on the high pressure pipeline between Városföld in Hungary and Slobodnica in Croatia. FGSZ Ltd (Hungary) and Plinacro (Croatia) held negotiations from 2007 on the inter-connection of their high pressure transmission systems. The pipeline has a length of 205 km in Hungary, and 88 km in Croatia. Maximum capacity of the pipeline is 6.5 bcm/year. The pipeline will be able to transmit gas to both directions, using the supply option from the Adria LNG terminal (island of Krk) to be implemented later. The €395m pipeline was built co-financed by the European Union.
The interconnection is of outstanding importance in respect of one of the energetic priorities of the European Union, i.e. the implementation of the North-South Gas Corridor, through which further gas sources become available for the Central Eastern and South Eastern European region and it is another step towards the establishment of a unified, transparent gas market.
