A project aiming to triple the capacity of the Greek-Italian electrical grid interconnection is set for a challenging stage that entails thorough mapping of the seabed along the existing line’s 220-km route.

Survey work for this project is planned to begin in early 2024 following an agreement reached earlier this week at a wide-ranging Athens meeting between Giuseppina Di Foggia, CEO at Italian grid operator TERNA, and Manos Maousakis, the chief executive at Greek power grid operator IPTO.

The TERNA chief was joined by a team that included the company’s CFO as well as the head of major projects and international development.

Greece is under growing pressure to establish new export outlets for the country’s excess renewable energy. The country’s electricity exporting activity is becoming more frequent during midday hours. Also, Italy, it should be pointed out, is Europe’s biggest electricity importer.

According to sources, the Greek and Italian power grid operators are exploring all options, based on the respective experience of each company, to boost the capacity of the Greek-Italian subsea cable link from 500 MW to 1,500 MW as swiftly and efficiently as possible.

At this week’s meeting, held Tuesday, IPTO and TERNA also agreed on the need for new corridors transporting RES production from southern to central Europe.

TERNA, Europe’s biggest operator, is a highly influential market player operating 26 international interconnections and present on three continents.
