Romania Imports Hungarian Gas as Bulgarian Supply Route Pauses for Capacity Work
Romania reversed its usual gas flow with Hungary, importing 0.6 million cubic metres through Szeged/Arad after supplies for its domestic market via Bulgaria were temporarily halted. Storage injections slowed, but Romanian facilities remained 80% full five weeks before the official winter season.
Cross-border flow reverses at Szeged/Arad
Romania began importing natural gas from Hungary after its usual supply route through Bulgaria was temporarily interrupted by pipeline capacity work, Capital reported. On the reporting day, 0.6 million cubic metres entered Romania through the Szeged/Arad interconnection. The gas was used both for domestic consumption and for continued injection into underground storage ahead of the cold season.
The direction was unusual for this part of the regional network. Romanian gas normally moves in the opposite direction, crossing the Transgaz system toward Hungary. The reversal illustrates how interconnected infrastructure can provide an alternative source when maintenance restricts a principal entry route, even if the replacement volume is relatively limited.
Bulgarian work halts Romania's main import route
Imports intended for the Romanian market stopped because work was under way on the upstream pipeline in Bulgaria. Ion Sterian, cited by Capital, said the Bulgarian operator was making connections as part of a project to increase annual capacity from 5 billion to 10 billion cubic metres. The previously announced work was expected to continue throughout that week.
Other cross-border movements did not stop completely. Transgaz's interactive data showed Romania continuing to transit 2.4 million cubic metres of gas for the Republic of Moldova. That volume entered from Bulgaria at Ruse/Giurgiu and left Romania through Iași/Ungheni. Romania was therefore still operating as a transit corridor even while imports for its own market were suspended on the Bulgarian route.
Storage injections slow before winter
The disruption reduced the amount of gas available for storage. Romania was injecting slightly more than 5 million cubic metres per day into underground facilities, compared with 12-13 million cubic metres per day in the previous week. The fall shows the immediate effect of the Bulgarian maintenance period on Romania's pre-winter stock-building rate.
Nevertheless, Romanian storage sites were 80% full with five weeks remaining before the official start of the cold season. That was above the European Union average of approximately 70%. The existing inventory provides a buffer against a short interruption, although a prolonged reduction in incoming volumes would make continued injections more dependent on alternative routes and domestic supply.
European storage levels diverge
The European Commission had dropped, for that year, the obligation requiring member states to fill storage facilities to at least 90% of capacity. Countries consequently set their own storage schedules. Capital reported that Poland had already reached 100%, while Italy and France also had high inventory levels.
Germany faced the most difficult position among the countries cited. Its storage facilities were only 56% full, despite Germany being the European Union's largest economy and the continent's largest gas consumer. Against that regional backdrop, Romania's 80% level reduced the near-term risk from the Bulgarian works, but the sharp decline in daily injections highlighted the operational value of the Hungarian connection. For producers, traders and system operators, the episode showed that bidirectional capacity can preserve supply flexibility when a major corridor is temporarily unavailable.
