Southern Interconnection Croatia/BiH

The southern interconnection of the gas transmission systems of Croatia and Bosnia and Herzegovina, on the route Zagvozd - Imotski - Posušje - Tomislavgrad - Zenica with the branch to Mostar, is of the strategic importance for the security of supply of Bosnia and Herzegovina, since this country currently depends on only one entrance into the gas transmission system (from Serbia via The Republika Srpska).
The project ensures diversification of routes and sources of supply (through the LNG terminal on the island of Krk, the future Ionian-Adriatic Pipeline and other supply routes that go through the Republic of Croatia) and further gasification of BiH, which will result in the increased transit of natural gas through the Republic of Croatia.
Croatian sections of the southern interconnection Croatia - Bosnia and Herzegovina include the section Dugopolje - Zagvozd with a total length of 52 km, and the section Zagvozd - Imotski - border of Croatia and Bosnia and Herzegovina with a total length of 22 km, while on the Bosnian and Herzegovinian side the total length of the route is 169 km. The anticipated interconnection capacity is up to 1.5 billion m3 per year.
The project completion is planned in 2024.
