US liquefied natural gas exporter Venture Global and Greece’s Atlantic-SEE LNG Trade on Thursday announced doubling of ‌volumes under their long-term supply agreement, as Europe seeks to bolster energy security.

The Greek joint venture will now take at least 1 million metric tons per ⁠year of LNG from Venture starting in 2030 for 20 years, under the revised agreement, the companies said in a statement.

Atlantic-SEE, formed by Aktor Group and DEPA Commercial, plans to import LNG into Greece and distribute it across Central and Eastern Europe via the “Vertical Corridor” ‌network ⁠aimed at diversifying regional gas supply routes.

European buyers have been locking in long-term LNG contracts to reduce exposure to volatile spot markets ⁠and secure supply, following disruptions linked to geopolitical tensions.

The deal builds on Venture Global’s investment in regasification ⁠capacity at the Alexandroupoli LNG import terminal. It holds about 25% capacity there, ⁠positioning the facility as a gateway for US gas into southeastern Europe. [Reuters]
