Slovakia has announced the possibility of halting electricity supplies to Ukraine amid a conflict over the transit of Russian oil through the Druzhba pipeline. At the same time, Slovakia and Hungary have already suspended diesel fuel exports.
Slovak Prime Minister Robert Fico stated that Bratislava may halt electricity supplies to Ukraine if suspicions are confirmed regarding the deliberate delay in restoring the damaged section of the Druzhba pipeline. He also allowed for a review of political support for Ukraine if the situation escalates.
The Druzhba pipeline, through which Russian oil is supplied to Slovakia and Hungary, was damaged as a result of a Russian attack on January 27, which led to the suspension of resource transportation.
Slovakia and Hungary have already suspended diesel exports
In parallel with the political statements, Slovak oil refiner Slovnaft has temporarily suspended diesel fuel exports to Ukraine. The decision was made after the Slovak government introduced a state of emergency in the energy sector and released part of its strategic oil reserves to secure the domestic market. The government stated that all produced resources would be directed to domestic consumption.
A similar decision was made by Hungary, which also suspended diesel supplies to Ukraine until the restoration of Russian oil transportation through Druzhba.
According to NaftoRynok estimates, the Hungarian-Slovak direction accounted for about 11% of diesel fuel imports to Ukraine in January 2026. At the same time, given seasonally low demand and the possibility of replacing supplies from other directions, the suspension of exports is not critical for the market and is unlikely to lead to a significant increase in prices.
Risks for the electricity market
Despite the harsh rhetoric of the Slovak government, no actual restrictions on electricity supplies to Ukraine have been introduced so far. Ukraine continues to import electricity from EU countries, including the Slovak and Hungarian directions. According to ExPro data, in February Ukraine has already imported 147 thousand MWh from Slovakia (18% of the total volume) and 402 thousand MWh from Hungary (50% of the total volume).
