Greek power grid operator IPTO has submitted a Green Aegean grid interconnection plan, envisaged to run from Greece to Germany’s south, to the ten-year development plan of ENTSO-E, promoting closer cooperation across Europe’s TSOs to support the implementation of EU energy policy and achieve Europe’s energy and climate policy objectives.

The project’s inclusion in the development plan of ENTSO-E, representing operators from all of the EU’s 27 member states, would represent a significant first step towards PCI/PMI status for the project, securing EU funding, as planned by IPTO.

IPTO prefers a HVDC-technology subsea route for the Green Aegean grid interconnection that would pass through the Adriatic Sea to Slovenia, followed by an overland route to Austria and Germany’s south.

IPTO recently held related talks with TenneT, Germany’s biggest power grid operator, and Slovenian operator ELES.

TenneT has expressed strong interest in the Green Aegean grid interconnection and the prospect of collaborating with IPTO on the project’s development for a link with Germany’s grid in the southern part of the country.

HVDC-technology enables transmission of large quantities of electricity over long distances via submarine cables, as well as fast and accurate control of power flow, enhancing grid stability.
