Croatian and Slovenian gas transmission operators, Plinacro and Plinovodi, have agreed to strengthen energy connectivity between the two countries by increasing transport capacity at the Rogatec gas interconnection point, improving the flow of natural gas from Croatia toward Slovenia.
The agreement sets out joint efforts to upgrade gas infrastructure and enable larger volumes of cross-border gas transmission. The planned expansion is expected to reinforce supply reliability, strengthen regional energy resilience, and improve integration between interconnected gas systems in Southeastern Europe.
The project will partly rely on ongoing improvements to Croatia’s gas transmission network, which are designed to expand overall transport capacity and improve access to diversified gas supplies for neighboring markets. Both operators emphasized the importance of long-term cooperation in building a more secure and interconnected regional energy framework.
According to Plinacro, the Rogatec interconnection could reach a capacity of up to 170,000 cubic meters per hour once pipeline upgrades financed through Croatia’s National Recovery and Resilience Plan are completed. Key infrastructure works include the Bosiljevo–Sisak and Kozarac–Sisak pipeline sections.
Provided that upstream pressure conditions are met, the expanded capacity could become operational by the end of December, marking another step toward stronger regional energy cooperation and improved supply security across interconnected gas markets.
