Ukraine unlocks new gas route to import up to 1 bcm per annum from Greece

The corresponding decision was endorsed at the regulator’s meeting on May 27, 2025, an Ukrinform correspondent reports.

In particular, the NEURC received a joint letter from the gas transmission system operators of Bulgaria (Bulgartransgaz), Greece (DESFA SA), Moldova (VestMoldTransgaz SRL), Romania (Transgaz SA) and Ukraine (Gas Transmission System Operator of Ukraine, GTSOU) with a proposal to create a joint product for gas transportation using the capacity of the Trans-Balkan gas corridor.

Separately, GTSOU applied to the regulator for approval to hold an auction for capacity allocation at interstate connectors with Moldova and Romania as part of the joint product.

Based on the decision, the auction will be held on the Regional Booking Platform (RBP) according to the following schedule: for June 2025 – on the last Thursday of the month preceding the capacity usage period; for July-October 2025 – on the fourth Monday of the month preceding the capacity usage month.

“This launch opens up additional opportunities for natural gas imports in the amount of up to 100 million cubic meters per month as soon as this summer,” GTSOU Director for Regulatory Issues Oksana Kryvenko said at the regulator’s meeting.

From autumn 2025, up to 200 million cubic meters per month can be imported via the Trans-Balkan corridor, Kryvenko added.

As noted by the NEURC, the adopted decision provides for a single auction to be held for capacity allocation at all points of the Trans-Balkan corridor along the natural gas transportation route from Greece to Ukraine, i.e. approximately 3 million cubic meters per day.

A reminder that, in February 2024, the gas transmission system operators of Ukraine, Romania and Moldova began consultations to expand gas reverse flows via the Trans-Balkan corridor.

In 2023, Ukraine imported over 550 million cubic meters of gas via the Trans-Balkan corridor, mainly for storage purposes.
