The electricity interconnection of Crete with Attica is currently the largest investment both in terms of cost and in terms of technical complexity for the transmission of electricity made in Greece with the aim of ending the electrical isolation of Crete from the mainland electricity grid and covering the increased future needs of the island Note that this project is the largest in length and depth under construction cable submarine and underground high voltage direct current interconnection in Greece The proposed project concerns the completion of Phase II of the project that makes it possible to supply a significant part of the island's load by ESMIE and in combination with Phase I of the interconnection of Crete with the Peloponnese leads to the complete de-dependence of the island from the fuel oil production units that until now ensured its energy adequacy. It is a project of strategic national importance with great added value that has been characterized by the Decision of the Minister of Energy ILVF82954oik 18457812122017 as a project of general importance for the country's economy The two phases of the Interconnection constitute the largest project in terms of technological innovation and complexity budget that has been implemented to date in the Greek Electricity Transmission System.
