Expansion Background

The pipeline expansion has been approved for inclusion on the European Commission's Projects of Common Interest (PCI) list (under the project code TRA-N-524), meaning it is eligible to receive public funding from the EU. According to the European Commission, "The objectives of [this project] are: reducing the flow direction switch operation time, developing the transmission capacity in HU->SK and SK->HU directions from interruptible capacity to non-interruptible (firm) capacity, enhancement of Exit transmission capacity with 102 GWh/d in HU->SK direction and enhancement of Entry transmission capacity with 26 GWh/d in SK->HU direction at Balassagyarmat with adding power on Szada compressor station. Equal level of transmission capacities will be available in both directions at the SK-HU interconnection."[1]

In February 2020, Hungary and Slovakia signed a memorandum of understanding on expanding the interconnector's bidirectional capacity to 5.3 billion cubic meters per year. The currently operating interconnector has capacity of 4.5 billion cubic meters from Slovakia to Hungary and an interruptible capacity of 1.8 billion cubic meters in reverse mode.[3]
