Green Aegean Interconnector: Reviving Energy Links Between Germany and Greece.

The Green Aegean Interconnector is an ambitious initiative aimed at providing a crucial energy link between Greece and Germany.
Following the German elections and the almost certain appointment of Christian Democrat Friedrich Merz as German Chancellor, who has a close relationship with Greek Prime Minister Kyriakos Mitsotakis, the project has gained new momentum.
This project is set to facilitate the transport of surplus wind energy generated in the Aegean Sea to the industrial centres of Central Europe.
Several key players are involved in this large-scale endeavour. The Independent Power Transmission Operator (IPTO) in Greece is at the forefront, while significant participation from major Greek corporations is anticipated.
Preliminary discussions have indicated enthusiasm from these business groups, suggesting a strong collaborative effort.
The project has been highlighted in IPTO’s Preliminary Ten-Year Development Plan for 2025-2034. It has also been identified by the European Network of Transmission System Operators for Electricity (ENTSO-E) as one of the crucial electricity transmission projects in Europe for the next decade.
The estimated cost of the interconnector stands at €8.1 billion, with a projected completion date in late 2035.
Discussions with transmission system operators across Austria, Slovenia, and Germany will recommence in 2025, following the completion of a feasibility study.

The initial routing plan aims to pass through the Adriatic Sea, which strategically avoids potential delays from the Western Balkans and Croatia.
The interconnector will travel north from Slovenia to Austria and then to Munich, a key industrial hub in Germany.
There is also potential for smaller interconnections to support other Balkan energy markets. Recently, Croatia’s transmission system operator (HOPS) has engaged with IPTO to explore possibilities for inclusion in this vital energy project.
On the Greek side, Grant Thornton is currently conducting a preliminary feasibility study to ensure the interconnection’s viability and effectiveness.
Frequently Asked Questions
What are the main goals of the Green Aegean Interconnector project?
The Green Aegean Interconnector aims to create a strong energy link between Greece and Germany. It focuses on efficiently transferring renewable energy, especially surplus wind power, to meet growing energy demands in Central Europe.
The project also seeks to improve energy security and support the transition to sustainable energy sources.
How does the Green Aegean Interconnector promote energy cooperation between Germany and Greece?
This interconnector establishes a direct connection for energy exchange, allowing Greece to export renewable energy to Germany. By integrating their energy markets, both countries benefit from enhanced energy security, better resource utilisation, and a greater capacity for managing energy from variable sources.
What environmental effects are expected from the interconnector connection?
The project is designed to have minimal negative environmental impacts.
Efforts are being made to protect local ecosystems during the construction and operation of the interconnector.
Fossil fuel dependency is expected to decrease, leading to lower greenhouse gas emissions, which supports the goals of climate change mitigation.
Which renewable energy sources will the interconnector mainly use?
The interconnector will mainly harness wind energy generated in the Aegean Sea. It may also integrate other forms of renewable energy, such as solar power, depending on the region’s capabilities and resource availability.
This focus on renewables aligns with efforts to establish a sustainable energy framework.
How will the interconnector support the European Union’s energy ambitions?
The Green Aegean Interconnector aligns with the European Union’s goals for energy independence and sustainability. It contributes to the EU’s commitment to increasing the share of renewable energy and reducing carbon emissions across member states, promoting a greener energy landscape.
What steps are being taken to ensure the reliability and security of the energy link?
To maintain the reliability of the energy link, the project will implement advanced technologies for monitoring and control.
Regular maintenance and risk assessments will be part of the operational plan.
Additionally, collaboration between Germany and Greece will enhance the operational security of the interconnector.
