Background
Some of the pipelines comprising the Hungary-Slovenia-Italy interconnector network were approved as project number 6.23 on the European Commission's Projects of Common Interest (PCI) list, meaning they would have received public funding from the EU.[17][18] The project was also listed in 10-year natural gas development plans for Slovenia, Hungary and Italy.[6][19][20]
According to the European Commission, "The PCI will establish a bidirectional interconnection between SI and HU gas transmission systems and with that a connection of the national gas markets. It will improve possibilities for diversification of gas sources (LNG sources from the Adriatic region and any other sources), which are available in SI and enable access to gas storages in HU for SI users. The security of supply (N-1 criteria) will be improved for the existing SI gas system as well as for the HU gas market to a certain extent. The length of the gas pipeline between Nagykanizsa (HU) and Kidrievo (SI) will be approximately 114 km [about half of the total pipeline length] and the expected maximum transmission capacity will be up to 12.86 GWh/d by 2022 and 38.1 GWh/d (3.4 mcm/d) by 2023."[1]
According to the European Network of Transmission System Operators for Gas (ENTSOG) Project-Specific Cost-Benefit Analysis for TYNDP 2020, the project was a part of the "EAST 11b" group, which also included the Pince-Lendava-Kidričevo Gas Pipeline and the Šempeter-Vodice Gas Pipeline. The Nagykanizsa-Kozármisleny and Nagykanizsa-Tornyiszentmiklós pipeline segments (TRA-N-325) were a part of the Slovenian-Hungarian interconnector which in turn was a part of the Hungary-Slovenia-Italy Interconnector Gas Pipeline network project.[21]
In Slovenia, according to Plinovodi's Ten-Year Gas Transmission Network Development Plan for the 2021 - 2030 Period, construction would have taken place in two stages. Stage one would have consisted of a 31 km pipeline from Pince to Ljutomer as well as a border metering and control station in Pince. Stage two included a 43.5 km pipeline from Ljutomer to the compressor station (CS) Kidričevo, an upgrade of the cross-border metering and control station Pince, the expansion of CS Ajdovščina and a border metering and control station Vrtojba.[22]
FGSZ listed four proposals for the pipeline in its "projects subject to further investigation" in its July 2020 10-year network development plan: (1) a 41 km pipeline from SI/HU border to Tornyiszentmiklósto Nagykanizsa with a capacity of 0.4 bcm/y, and a metering station in Tornyiszentmiklósto (2) same as the first option, but with a total capacity of 1.66 bcm/y, due to the additional inclusion a new CS at Nagykanizsa and 150 km of pipeline from Nagykanizsa to Kaposvár to Kozármisleny (3) same as the second option but with a larger CS in Nagykanizsa, bringing the total capacity to 2 bcm/y (4) same as three but with an additional compressor station in Kozármisleny, bringing the total capacity to 3.2 bcm/y. The expected commissioning date varies based on proposal, the first (1) is Jan 2023, (2) is January 2025, (3) and (4) are January 2027. [14]
In December, 2022, a deal was made between Plinivodi d.o.o and Algiers (the Algerian gas supply company) for 300mn cubic meters of gas a year to supply this pipeline.[23]
As of 2025, the only pipeline projects active in the network, according to the TYNDP 2024 report are the Pince - Lendava - Kidričevo Gas Pipeline and the Šempeter-Ajdovščina Gas Pipeline, which has been at times considered part of the interconnector.[16]
The Hungary-Slovenia-Italy Interconnector gas pipeline network has a similar structure to the more recent Italy-Slovenia-Hungary H2 corridor (ENTSOG TYNDP 2024 project code H2T-N-1356).[16]
Šempeter-Vodice Gas Pipeline
According to the European Network of Transmission System Operators for Gas (ENTSOG) 2020 TYNDP, construction was set to take place from March 2023 to December 2026. Commissioning was set for 2026.[24]
The project was made up of three phases: M3/1a Šempeter - Ajdovščina, M3/1b Ajdovščina - Kalce, and M3/1c Kalce - Vodice.[24] ENTSOG and the Eastern Europe Natural Gas Partnership (EE-NGP) expected all three to be commissioned in 2026,[24] while Plinovodi, as of April 2021, did not list expected start dates any of the three.[2] As of 2025, the project is considered to be shelved, since there have been no updates in at least two years.
Pince-Lendava-Kidričevo Gas Pipeline
The project is a part of the European Union's Projects of Common Interest (PCI), making it eligible for public funding. The Connecting Europe Facility has provided the project with a €344,500 grant for preparatory studies.[25]
It was listed amongst the "projects in preparation in the 2021 – 2023 period" in Plinovodi's Ten Year Gas Transmission Network Development plan for the 2021-2030 period.[26]
According to Plinovodi's Ten Year Gas Transmission Network Development plan for the 2022-2031 period, the project is to take place over three stages- Stage one: Pince-Lendava, Second stage: Lendava-Ljutomer, Third stage: Ljutomer-Kidričevo.[12]
