Reshaping the Energy Future of Southeast and Central Europe

Who We Are

Gastrade S.A. was founded in 2010 with a clear mission to design, develop, and operate modern natural gas infrastructure, guided by safety, reliability, and respect for the environment and society.

We are the first company in Greece to obtain an Independent Natural Gas System License, reflecting our leading role in the transformation of the national energy sector and our long-term commitment to strengthening energy security and market development.

At a time when floating LNG infrastructure was still an emerging concept globally, we initiated the development of the Alexandroupolis Terminal, helping shape the regulatory and operational framework that contributed to the broader development of FSRU infrastructure across Europe in the years that followed.

Today, with a strategic focus on supply security, diversification of energy sources, and regional interconnectivity, we continue to contribute to a more resilient and sustainable energy landscape for Greece and Southeast Europe.

Who We Are

What We Do

We build energy infrastructure designed for long-term regional impact.

Since October 2024, we have been operating the Alexandroupolis Independent Natural Gas System, one of the most significant energy infrastructure projects in Southeast Europe.

The project establishes a new energy gateway for the region, providing access to diversified and reliable energy supply sources and routes, while strengthening energy security and affordability across Southeast and Central Europe.

In parallel, we are advancing the development of additional energy infrastructure that will further strengthen system capacity, flexibility, and regional resilience.

We are also a key participant in the European Vertical Gas Corridor initiative, supporting the uninterrupted flow of natural gas from Greece toward Southeast and Central European markets, and contributing to energy security, affordability, and regional cooperation.

Our Shareholders

Our shareholder structure brings together five equal partners in a strong public-private partnership with a European footprint, adding significant strategic value to the project.
