Greece’s LNG lifeline to Ukraine: strategic gains or deeper U.S. orbit?

As Ukraine grapples with escalating revelations from the explosive Energoatom corruption scandal – implicating figures close to President Volodymyr Zelenskyy and prompting investigations by the National Anti-Corruption Bureau (NABU) – Athens has suddenly emerged as a focal point in the broader geopolitical chessboard.

The highlight of Zelenskyy’s whirlwind visit to the Greek capital on 16 November was the signing of a declaration of intent between Greece’s DEPA Commercial and Ukraine’s Naftogaz, paving the way for U.S. liquefied natural gas (LNG) supplies to Ukraine via Greek infrastructure from December 2025 to March 2026.

Yet the ceremony’s optics – attended not just by Prime Minister Kyriakos Mitsotakis and Zelenskyy, but also by U.S. Ambassador to Greece Kimberly Guilfoyle – have sparked whispers in diplomatic circles: Is Greece evolving into a de facto U.S. protectorate on Southeast Europe’s energy frontier?

The deal secures vital winter gas for Ukraine, which has seen its energy infrastructure ravaged by Russian strikes, reducing domestic production by up to 50% in recent months.

Under the agreement, U.S. LNG will flow northward through the “Vertical Corridor” – a multi-nation pipeline network linking the transmission operators of Greece (DESFA), Bulgaria (Bulgartransgaz), Romania (Transgaz), Moldova (Vestmoldtransgaz), and Ukraine (GTSOU) – via the Revithoussa and Alexandroupolis terminals.

This “Route 1” pathway, already regulatory-approved, positions Athens as a pivotal gateway for American energy exports to Eastern Europe, bolstering the corridor’s capacity to handle up to 10 billion cubic meters annually of non-Russian gas.

For Mitsotakis, the pact represents a “decisive step toward regional stability,” transforming Greece into a linchpin of Europe’s REPowerEU strategy to phase out Russian hydrocarbons by 2027.

Zelenskyy hailed it as a “vital lifeline” for Ukraine’s “energy-starved” grid, thanking Greece, the U.S., and even President Donald Trump for enabling deliveries that could offset losses from wartime destruction.

Deliveries are slated to ramp up in January 2026, with DEPA’s 40% stake in Atlantic-SEE facilitating the regasification and transit process.

The agreement’s timing amplifies its symbolism. It follows hot on the heels of the November 6-7 P-TEC Summit in Athens, where over 80 U.S. officials, EU energy ministers, and LNG executives—led by U.S. Energy Secretary Chris Wright—charted transatlantic energy pathways to counter Moscow’s influence.

Guilfoyle’s prominent role at the Maximos Mansion signing – standing alongside Mitsotakis, Zelenskyy, and Greek Energy Minister Stavros Papastavrou – fueled speculation that Washington seeks not just facilitation, but hands-on stewardship of this “energy bridge.”

Analysts interpret this as a signal of deepening U.S. leverage, aligning with Trump’s push to supplant “every last molecule of Russian gas” with American LNG exports.

The Zelenskyy-Mitsotakis summit at Maximos Mansion carried unmistakable political heft. Mitsotakis reaffirmed Greece’s “unwavering commitment” to Ukraine’s sovereignty and territorial integrity, while lambasting Russian assaults on civilian targets.

Zelenskyy reciprocated with gratitude for Athens’ multifaceted aid—humanitarian, military, and now energetic—while spotlighting Ukraine’s defence innovations and urging intensified European sanctions on Russia.

Discussions also touched on Greek firms’ potential role in Ukraine’s postwar rebuilding, with Alexandroupolis – already a hub for U.S. military aid transshipments – poised as a dual-use energy and logistics nexus.

Yet this pact unfolds against a backdrop of turmoil in Kyiv. Operation Midas, NABU’s 15-month probe codenamed after the myth of unchecked greed, has exposed a sprawling graft network at Energoatom, Ukraine’s nuclear powerhouse that generates over half the nation’s electricity.

Zelenskyy has demanded resignations, fired Energoatom’s board, and imposed sanctions, but the scandal risks eroding his Servant of the People coalition’s parliamentary majority amid public fury.

For Greece, this energy entente presents a double-edged sword. It cements Athens’ ascent as a European gas hub – leveraging Alexandroupolis’ floating storage unit and the Greece-Bulgaria interconnector to reroute flows away from Gazprom’s TurkStream – while advancing de-Russification goals shared by the EU’s 27 members.

Government insiders insist Greece is “fulfilling its pivotal role” in collective European resilience.

But critics question whether this alignment – forged under Washington’s watchful eye – curtails Athens’ foreign policy autonomy, especially as U.S. LNG floods regional markets at premiums that could strain Greek consumers long-term.
