Interconnection of the Cycladic Islands to the Mainland Grid

In this paper the main results of a study concerning the optimum solution for the electrification of the Cycladic islands, in a long term period, are presented and discussed. There are three main Scenarios: (A) the extension of the existing interconnection to the main land grid and development of local diesel power stations, (B) the construction of a new interconnection to the main land, (C) the development of the existing and new diesel power stations. A brief presentation of the possibilities offered by the recent technological progress on the submarine transmission that are taken into account in the study is also made. The three Scenarios are compared from the technical and economical point of view and their main advantages and disadvantages are discussed.
