Ukraine Diversifies Energy Supply: Will the Vertical Corridor Gain Momentum?
Ukraine is making a strategic push to diversify its energy sources, recently launching two new natural gas import routes – Route 2 and Route 3 – as part of the ambitious Vertical Corridor initiative. This project, involving Ukraine, Moldova, Romania, Bulgaria, and Greece, aims to reduce reliance on traditional supply lines and bolster energy security. However, initial auctions for capacity on these routes have yielded surprisingly limited results, raising questions about the project’s immediate future.
The Vertical Corridor: A New Energy Map for Southeast Europe
The Vertical Corridor isn’t just about Ukraine; it’s reshaping the energy landscape of Southeast Europe. The initiative leverages existing and planned infrastructure to create alternative pathways for gas delivery, reducing dependence on single suppliers and increasing regional energy resilience. This is particularly crucial given the geopolitical volatility impacting energy markets globally. According to the International Energy Agency’s July 2023 Gas Market Report, diversifying gas supply is a key priority for Europe.
Route 2 focuses on bringing Liquefied Natural Gas (LNG) from the Alexandroupolis terminal in Greece to Ukraine. This involves a journey through the Interconnector Greece-Bulgaria (IGB), then onward through Romania and Moldova. Route 3, meanwhile, targets Azeri gas, utilizing the same Balkan corridor after originating at the intersection of the IGB and the Trans-Adriatic Pipeline (TAP). Both routes represent a significant investment in infrastructure and a commitment to a more diversified energy future.
Initial Auctions: A Slow Start, But Not a Setback?
Despite offering substantial tariff reductions – ICGB and Ukraine’s Gas Transmission System Operator offered discounts of up to 46% – the first auctions held on December 22nd, 2025, failed to attract any bookings. Experts attribute this to the limited preparation time following the recent approval of the capacity products. Companies need time to assess the viability of using these routes, secure long-term supply contracts, and adjust their logistical operations.
This isn’t necessarily a sign of failure. Similar situations have occurred with new energy infrastructure projects elsewhere. For example, the initial uptake of capacity on the Nord Stream 2 pipeline (prior to its suspension) was also slower than anticipated due to regulatory hurdles and market uncertainty. The key will be sustained engagement with potential users and a clear demonstration of the routes’ long-term reliability and cost-effectiveness.
The Existing Route 1: A Cautionary Tale
The lack of interest extends to the existing Route 1, which connects the Revythoussa LNG terminal in Greece to Ukraine and has been operational since July 2025. An auction held on December 22nd for January capacity also failed to secure any bookings, despite offering 4.89 million cubic meters of daily capacity. This suggests that current market conditions, or perhaps pricing, are not yet conducive to widespread use of these routes.
Pro Tip: Keep a close eye on LNG spot prices and regional demand. Fluctuations in these factors will significantly impact the attractiveness of these import routes.
Future Trends and Potential Impacts
Several factors will shape the future of the Vertical Corridor:
- Increased LNG Demand: Europe’s ongoing shift towards LNG as a replacement for Russian gas will drive demand for import capacity, potentially benefiting Route 2.
- Azerbaijani Gas Expansion: Azerbaijan is actively increasing its gas production and export capacity. Successful expansion of the Southern Gas Corridor will be vital for Route 3’s success.
- Regional Infrastructure Development: Further investments in pipeline infrastructure within the Balkan region, particularly in Romania and Bulgaria, will be crucial for maximizing capacity.
- Geopolitical Stability: Continued geopolitical instability in the Black Sea region could increase the strategic importance of alternative supply routes like the Vertical Corridor.
Did you know? Ukraine has been actively working to integrate its gas transmission system with the European network, aligning with ENTSOG standards to facilitate cross-border gas flows.
FAQ
- What is the Vertical Corridor? A regional energy initiative aimed at diversifying gas supply routes to Ukraine and Southeast Europe.
- Why were the initial auctions unsuccessful? Limited preparation time for potential users is the primary reason cited.
- What role does LNG play in this initiative? Route 2 is specifically designed to import LNG from Greece.
- Is this project viable in the long term? Its success depends on sustained investment, regional cooperation, and favorable market conditions.
The Vertical Corridor represents a bold attempt to reshape Ukraine’s energy security and contribute to a more resilient energy market in Southeast Europe. While the initial hurdles are significant, the long-term potential remains substantial. Continued monitoring of market dynamics, infrastructure development, and geopolitical factors will be essential to assess its ultimate success.
