Croatia - Slovenia Interconnection (lučko - Zabok - Rogatec)

Along with the existing gas pipeline in the direction Lučko-Zabok-Rogatec (SI), a new interconnection gas pipeline has been planned. It would significantly increase the capacity of the interconnection between the Croatian and the Slovenian transmission system in that direction. Considering the existing and new supply routes, primarily relating to the LNG terminal and the Croatian storage potentials, this new interconnection gas pipeline opens significant possibilities of gas transmission in both directions.

The capacity of the gas pipeline would be up to 5 bcm/y in both directions, thus significantly increasing the capacity of the interconnection at Rogatec which currently amounts to 1.8 bcm/y in the direction from Slovenia to Croatia and 0.26 bcm/y in the direction from Croatia to Slovenia, respectively. In this way, the construction of this gas pipeline significantly contributes to the security of supply of the Croatian market and of the market of the southeast Europe.
 
The interconnection Croatia-Slovenia in the direction Lučko-Zabok-Rogatec (SI) comprises the following gas pipeline projects:

• Lučko-Zabok, of nominal diameter 700 mm, the maximum operating pressure 75 bar, and the length of 36 km. The implementation of the project has been planned in two phases. The first phase of the project is the construction of the section of the gas pipeline from the gas node Lučko to BIS Rakitje, while the second phase is the construction of the gas pipeline from BIS Rakitje to GN Zabok.
• Zabok-Jezerišće, of nominal diameter 700 mm, the maximum operating pressure 75 bar and the length of 25 km. 
• Jezerišće-Sotla, of nominal diameter 700 mm, the maximum operating pressure 75 bar and the length of 8 km. 

 For this project the building permit has been obtained
