5.1.5 Hungary

The picture below illustrates the supply corridors for Hungary. The main supply corridor is from Ukrainian direction which delivers most of the import gas under normal conditions (marked as HU1). The second supply corridor through Austria is marked as HU2, which is also of great importance. The third supply corridor through Croatia is marked as HU3. The interconnector between HU and HR has been designed as bi-directional, however, due to incomplete investment on the HR side (lacking compressor station) currently it is only capable to offer firm capacity from HU towards HR. Through the increased use of the compressor station on the HU side (which necessitates a pressure management agreement between the TSOs) the capability of firm capacity from HR to HU of about half of the entire capacity of the interconnector could be created. The HU TSO is ready to implement this temporary solution until the necessary investments are made on the HR side to ensure full HR>HU capability. In case of supply disruption on the Ukrainian/Hungarian interconnector, the main import supply corridor is the HU2.The remaining capacity that could be used in case of supply disruption (Ukraine) is supply from the Hungarian storages and domestic production points. During the Ukraine disruption Hungary is the main supply direction of gas for Romania. A supply corridor H4 will start in Q1/2014. The reverse flow in direction RO>HU will start with a minimum capacity and will increase to planned full capacity (51 GWh/d) in 2016. In 2015 a new cross border point will be commissioned between Hungary and Slovakia. A new interconnector is under preparation between Slovenia and Hungary, the estimated commissioning at Hun- garian side is 2017 and at Slovenian side is one year later.
