A new agreement reached in Athens, on March 27th, marks a key step forward for energy cooperation in Southeastern and Central Europe.

Transmission system operators (TSOs) from Greece (DESFA), Bulgaria (Bulgartransgaz), Romania (TRANSGAZ SA), Moldova (VESTMOLDTRANSGAZ), and Ukraine (Gas TSO of Ukraine), together with ICGB, have aligned with the European Commission on the commercial development of the Trans-Balkan Pipeline as part of the Vertical Corridor.

A more structured and competitive framework

The agreement introduces a long-term, EU-compliant approach to managing the corridor. It includes:

• A transparent pricing structure across all participating countries
• Alignment with EU Regulation 2017/460
• New tariffs designed to improve competitiveness

This creates a more reliable and predictable environment for market participants.

Increased flexibility for market players

Starting in October 2026 (gas year 2026–2027), TSOs will offer a wider range of capacity products; daily, monthly, quarterly, and annual, giving shippers greater flexibility and planning visibility.

Supporting the transition period

Until full implementation, TSOs have requested regulatory approval to extend current capacity products through October 2026. This is particularly important for maintaining supply stability in Ukraine during the transition.

A strategic step for Europe

As energy dynamics continue to shift, the Vertical Corridor is becoming a key route for diversification and regional integration. This agreement strengthens its role as a reliable and competitive energy link across Europe.
