Ukraine has started importing gas via a new route from Greece

Since July, Ukraine has begun importing natural gas via the joint route of the Trans-Balkan pipeline. The volume of gas transported corresponds to the booked capacity – approximately 162,000 cubic meters per day, reports the industry publication ExPro.
On July 1, the volume of natural gas imports to Ukraine increased by 42% compared to June 30, reaching 26.7 million cubic meters. This is the highest daily import value in four and a half months, since February 18, 2025.
Natural gas is transported from Greece through Bulgaria, Romania and Moldova to Ukraine and enters the "customs warehouse" of Ukrainian underground storage facilities.
"While in June almost all natural gas was imported directly into the Ukrainian gas transmission system, in July the majority of gas is entering the 'customs warehouse' of Ukrainian underground gas storage facilities – 24.7 million cubic meters on July 1, or over 92% of total imports. Only 2 million cubic meters, or 7.6% of imports, are going directly to the gas transmission system," reports ExPro.

If import volumes remain at this level, total gas imports to Ukraine in July may exceed 800 million cubic meters.
In the first half of 2025, Ukraine increased its natural gas imports more than 12-fold – to almost 2.1 billion cubic meters. This is the highest value for the first half of the year in the last five years, since 2020.
- In May 2025, the gas transmission system operators of Bulgaria, Greece, Romania, Moldova, and Ukraine officially announced the launch of a joint product for the supply of natural gas from Greece to Ukraine via the Trans-Balkan corridor.
- In June, Greece and Moldova simplified the transportation of gas to Ukraine via the Trans-Balkan route.
- The Trans-Balkan gas pipeline is a main gas pipeline that was previously used to supply Russian gas to the Balkans. In 2019, part of the Trans-Balkan gas pipeline infrastructure in Turkey and Bulgaria was included in the "Balkan Stream" gas pipeline.
