Greek state energy company DEPA and construction giant Aktor have signed a 20-year, €25 billion contract with US producer Venture Global to import up to 4 billion cubic meters of LNG annually starting 1 January 2030. The agreement, concluded through their joint venture Atlantic-See LNG Trade during the 6th Transatlantic Energy Cooperation Summit in Athens, is among the largest LNG supply deals in Eastern Europe.
The LNG will not only supply Greece but also neighboring markets, including Ukraine and other Eastern European countries seeking to reduce dependence on Russian gas.
In parallel, Atlantic-See LNG Trade signed memoranda of understanding with Ukraine’s Naftogaz for 0.7 bcm per year and with Romania’s Nova Power & Gas and Transgaz for 1.4 bcm annually, both covering 20-year periods beginning in 2030.
Venture Global, which already owns a 25 % stake in Greece’s Alexandroupoli floating LNG terminal, secures long-term offtake commitments under the deal. Commercial operations and market responsibilities will be managed by Atlantic-See LNG Trade, DEPA, and Aktor, which plan to further expand their LNG portfolio.
This agreement marks a major milestone for Greece’s energy transition, creating its first large-scale LNG import route from the US and reinforcing its role as a strategic energy hub in Southeastern Europe, contributing to regional diversification and supply security.
