Greece Natural Gas and Electricity infrastructure

In recent years, following the financial crisis and pandemic, Greece has emerged as a regional energy player, with major planned investments in natural gas infrastructure and electricity grid interconnections and upgrades. Through leveraging LNG imports and pursuing projects that will facilitate the northward flow of gas using existing pipeline infrastructure, Greece is moving towards its ambitious goal of becoming a net exporter of energy to the region and beyond. Since 2021, Greece has received over $18 billion in European Union’s Recovery and Resilience funding to support major modernization and upgrades in infrastructure, green energy and digitization projects.

Greece, which typically consumes about 6-7 billion cubic meters of gas a year, has increased capacity for LNG imports through the upgrade of its Revithoussa LNG terminal and the recently completed Alexandroupoli floating storage regassification unit (FSRU).  U.S. natural gas in the form of LNG now accounts for nearly 20 percent of Greece’s total gas demand, while it is over 60% of the LNG imported in the country.  In particular, in 2024 Revithoussa terminal received 27 LNG tankers of which 19 was US LNG. In terms of volume Greece imported a total of 21.4 TWh of LNG of which 13.4 TWh was US LNG. The above facts show that the US has emerged as the cornerstone of Greece’s LNG imports, underscoring the critical role of US LNG in ensuring Greece’s energy security amidst a shifting geopolitical landscape. These developments and several interconnector projects will bring meaningful opportunities for U.S. infrastructure, project management and energy firms in the years to come.


Key Interconnector and Natural Gas Infrastructure Projects include:

The Trans-Adriatic Pipeline (TAP) began operating in 2020 and supplies Greece about 1 bcm of gas per year (around 15 percent of its gas). . TAP is currently undergoing a capacity expansion plan, aiming to increase its operational capacity by adding an additional 1.2 billion cubic meters (bcm) of gas per year, with the goal of potentially doubling the pipeline’s capacity to 20 bcm/a by 2027 through further expansions and the addition of new compressor stations; this increased capacity is expected to be available starting in 2026.

The Interconnector Greece-Bulgaria Interconnector (IGB), completed in 2022, allows Bulgaria to import gas from TAP and from the Alexandroupoli FSRU. The IGB connects Greece with Bulgaria and is currently under further development to increase Greece’s stake in the transport of gas.

The Greece-North Macedonia Interconnector is expected to start construction in 2025 and will facilitate the transportation of natural gas between Greece and North Macedonia, with potential connections to other countries through LNG terminals in Greece and the Caspian region.

  • The Interconnector Greece-Turkey (ITG) is considering upgrading capacity to enable further imports Central Asia.

  • Liquefied Natural Gas (LNG) Infrastructure upgrades include the Revithoussa LNG Terminal, which facilitates 30-40% of Greece’s total gas needs.

  • The Alexandroupoli FSRU, operated by Gastrade, started commercial operations in October 2024 and increases Greece’s import capacity considerably.  

  • U.S. LNG developer Venture Global LNG has signed a 5-year deal with Gastrade SA to regasify up to 1 million metric tons of LNG in Alexandroupoli FSRU from two of its Louisiana export facilities.

  • Chevron has officially asked the Greek State for the rights to explore hydrocarbons in the concession areas south of the Peloponnese and on January 22, the Greek Ministry of Environment and Energy (MoEE) agreed to start the relevant licensing process. Currently, the two leading US firms in energy – Exxon and Chevron are active in Greece.  

  • On December 27th, the Ukrainian D.Trading  received its first Liquefied Natural Gas (LNG) shipment from the United States at the Revithoussa LNG terminal.  This delivery marks a key milestone in the efforts to enhance Ukraine’s energy security and diversify energy supplies across Europe.

Greece’s electricity transmission and distribution system operators are investing billions of euros to upgrade grid infrastructure and deploy smart technologies to accommodate over 20 gigawatts of renewable energy by 2027.  These grid upgrades include the construction of new substations, new high-voltage and low-voltage power lines, and the use of smart meters to monitor real-time energy production and usage.
