Greece and Ukraine have agreed a winter LNG supply deal: DEPA Commercial and Naftogaz will deliver US-origin liquefied natural gas from December 2025 to March 2026. Announced during President Zelensky’s visit to Athens, the pact aims to bolster Ukraine’s energy security amid repeated strikes on its infrastructure. Leaders also pledged deeper defence and maritime cooperation while Greece expands pipeline links and storage to serve as a regional gateway for American LNG.
Greece to Supply US-Origin LNG to Ukraine for Winter 2025–26, Bolstering Energy Security
Greece and Ukraine have agreed a winter LNG supply deal: DEPA Commercial and Naftogaz will deliver US-origin liquefied natural gas from December 2025 to March 2026. Announced during President Zelensky’s visit to Athens, the pact aims to bolster Ukraine’s energy security amid repeated strikes on its infrastructure. Leaders also pledged deeper defence and maritime cooperation while Greece expands pipeline links and storage to serve as a regional gateway for American LNG.

Greece Agrees to Send US LNG to Ukraine Ahead of Winter
Greece has signed an agreement to deliver US-origin liquefied natural gas (LNG) to Ukraine after its energy network was heavily damaged by Russian strikes. The deal — signed by Greece’s DEPA Commercial and Ukraine’s Naftogaz — covers supplies from December 2025 through March 2026 and was announced during President Volodymyr Zelensky’s visit to Athens.
The agreement followed talks between Zelensky and Greek Prime Minister Kyriakos Mitsotakis and was formalised at a ceremony attended by the U.S. ambassador to Greece, Kimberly Guilfoyle. A joint statement described the pact as "an essential step in strengthening regional energy cooperation and European energy security."
"Relations between our countries are taking on a crucial new dimension: that of a new secure energy artery, stretching from south to north, from Greece to Ukraine," Mitsotakis said at the ceremony.
Both leaders framed the supply arrangement as part of a broader push to reduce dependence on Russian gas. Mitsotakis called the deal "a decisive step toward definitive energy independence from Russian gas," while Zelensky described the pact as a "significant part of the comprehensive energy package we have prepared for this winter."
Zelensky warned the coming winter will be "a huge challenge for the Ukrainian people," citing near-nightly attacks on energy infrastructure. He thanked international partners and — in remarks reported by Greek officials — expressed gratitude to U.S. President Donald Trump "for the fact that we will be able to receive natural gas not only from Greece, but also (US gas) via Greece."
Wider strategic and infrastructure context
Greek officials said the agreement builds on recent investments and projects that position Greece as a regional gas hub. These include the Trans-Adriatic pipeline linkage to Bulgaria, which helps create a northward "vertical corridor" for gas deliveries to Bulgaria, Romania, Moldova, Ukraine, Hungary and Slovakia, and expanded storage capacity at the port of Alexandroupolis where American LNG can be received and stored.
The joint declaration accompanying the deal also commits both countries to deepen defence cooperation and maritime security, including the development and deployment of maritime unmanned systems, joint exercises and improved information-sharing on maritime threats.
Most European Union governments recently agreed to ban imports of Russian natural gas by the end of 2027 — a policy intended to reduce revenues that could finance the war — and Greece’s new arrangements aim to help provide alternative supplies to the region.
Zelensky’s trip to Athens marks the first presidential visit since 2023; he will continue his European tour with scheduled stops in France and Spain to seek further support for Ukraine’s energy resilience and defence needs.
