Key Facts
| Metric | 1 July 2025 | Context & Signal |
|---|---|---|
| Restarted route | Trans-Balkan (Revithoussa LNG / Greek hubs → UA) | Diversifies away from northern entry points |
| Booked capacity | ~162 000 m³ per day | Initial pilot volumes; slots still available |
| Total daily imports | 26.7 mcm (- highest since Feb-25) | Potential monthly inflow > 0.8 bcm if sustained |
| Bonded storage share | 92 % (24.7 mcm) injected tax-free | Positions UA UGS as transit-and-trading hub |
Why It Matters for Investors
-
Southern Diversification Pays
-
Trans-Balkan line was under-utilised after TurkStream switch-over. Reactivation creates two-way flexibility for EU shippers accessing Ukrainian underground gas storage (UGS) – Europe’s largest (31 bcm working capacity).
-
-
Bonded-Warehouse Arbitrage
-
Non-resident traders can park molecules in Ukrainian UGS duty-free, re-exporting to EU hub peaks. 2023/24 spreads topped €15-20/MWh during winter drawdowns.
-
-
Infrastructure Upside
-
Compression revamp & metering. Naftogaz seeks partners for turbine upgrades along the South-West corridor; EBRD and US DFC prepared to co-finance.
-
UGS modernisation. Priority sites: Bilche-Volytsya, Bohorodchany (proximity to Romanian border). CAPEX pay-back driven by storage spreads and firm capacity bookings.
-
-
Supply Sourcing Optionality
-
Access to LNG at Revithoussa and future Alexandroupolis FSRU plus Azeri gas via TAP enables portfolio blending. Investors in upstream Med & Caspian volumes gain year-round offtake route into Ukraine / CEE.
-
-
Regulatory Confidence
-
Ukraine aligned entry tariffs and network codes with EU’s Third Energy Package; ERRA-certified TSO ensures transparent capacity auctions on RBP/PRISMA platforms.
-
“The revived Trans-Balkan flow strengthens both Ukraine’s energy security and its emerging role as Eastern Europe’s balancing storage hub.”
— Serhii Makogon, former GTSOU CEO
