BAKU, Azerbaijan, March 31. ICGB, operator of
the Interconnector Greece-Bulgaria (IGB), together with partner
TSOs from Greece (DESFA), Bulgaria (Bulgartransgaz), Romania
(TRANSGAZ SA), Moldova (VESTMOLDTRANSGAZ) and Ukraine (Gas TSO of
Ukraine), in coordination with the European Commission, has agreed
on a joint commercial framework for the Trans-Balkan route part of
Vertical Gas Corridor, Trend reports via the ICGB AD.
“This outcome represents a significant step toward a
sustainable, EU-aligned framework, introducing a harmonized and
transparent tariff approach along the whole corridor. It reinforces
the role of the Vertical Corridor as a key route for secure and
competitive gas supply across Southeast and Central Europe,” said
the company.
Reportedly, as of October 2026, TSOs will offer yearly, quarterly,
monthly and daily capacity products at each IP along the
Trans-Balkan corridor at highly competitive tariffs, significantly
increasing the commercial attractiveness and market integration and
boosting liquidity among the respective markets.
For the interim period, TSOs have requested the relevant national
regulatory authorities to prolong the availability of existing
route capacity products until October 2026, thereby supporting the
continuity of supply to Ukraine.
The Trans-Balkan corridor is a regional gas transmission route
linking Greece, Bulgaria, Romania, Moldova and Ukraine, and forms
part of the EU-backed Vertical Gas Corridor initiative. The route
plays a growing role in diversifying supply sources—particularly
via LNG imports and Caspian gas—and in strengthening energy
security and market integration across Southeast and Central
Europe.
