- Strategically important infrastructure
The Alexandroupolis LNG Terminal is a key infrastructure project for Southeast Europe, strategically important for supply diversification and enhanced energy security.
The project is being developed through a Floating Storage and Regasification Unit (FSRU) located near Alexandroupolis, Greece. The terminal is connected to the Greek gas transmission system via offshore and onshore pipelines, enabling efficient transportation of regasified gas to regional markets.
One of the project’s key strengths is its integration with regional infrastructure, including the Greece–Bulgaria Interconnector (ICGB), providing direct access to the Bulgarian market and further expansion toward Romania, Serbia, and Hungary.
For Sustainable Energy Supply Ltd., the Alexandroupolis terminal represents a strategic opportunity for:
- Diversification of natural gas supply sources
- Reduced dependence on pipeline deliveries
- Increased flexibility in portfolio management
- Optimization of pricing conditions through access to global LNG markets
In the context of Europe’s evolving energy landscape, the Alexandroupolis LNG Terminal plays an important role in building a more integrated, competitive, and resilient energy market.
