Efforts to strengthen gas flows toward Eastern Europe have been reinforced through the extension of special capacity products along the Vertical Gas Corridor. The updated arrangement enables the continued transport of natural gas from Greece to Ukraine via designated routes, with the framework remaining in place until September 2026, ensuring stability in cross-border energy flows.
Under the current framework, capacity auctions will continue on a monthly basis, typically scheduled midweek shortly after the third Monday. These auctions are designed to provide consistent and reliable access to transport capacity for market participants, supporting transparency and efficient allocation within the regional gas market.
A key transit option, Route 3, allows gas entering the Greek system—whether through the DESFA network, the virtual trading hub, or the Revythoussa LNG terminal—to move northward. From the Nea Mesimvria entry point, volumes can be redirected via reverse flow along the Trans-Adriatic (TAP) pipeline, enabling supply to the Balkans and further onward to Ukraine. This route integrates multiple capacity products across platforms, including interruptible exit capacity and commercial reverse flow services, coordinated through established European trading systems.
To further enhance the corridor’s functionality, transmission system operators, together with the interconnector operator ICGB, have aligned with the European Commission on a revised tariff structure. This adjustment is aimed at improving the competitiveness and attractiveness of the route within the broader European gas network.
Overall, the extension is expected to preserve flexibility in regional gas supply while reinforcing diversification efforts across Southeastern and Eastern Europe, contributing to greater energy security in the region.
