On September 18-22, IENE’s researcher Mr. Alexandros Perellis visited the island of Kastellorizo, in the Dodecanese island group, off Rhodes, as part of the Institute’s study project concerning the island’s energy self-sufficiency. This study is now in progress, having commenced at the end of last year and scheduled for completion by December 2018.

More specifically, IENE’s visit to the island was mainly intended to investigate the energy end-use of the local consumers, for which a special questionnaire survey was conducted.In the framework of this survey a series of meetings and interviews with the local authorities, such as police, the military, port authorities, airport authorities, the municipality, private businesses and households were held,where valuable information for the end-use of energy on the island was collected. Moreover, a roadside and a peripatetic survey revealed much information for the terrain of the island,which indicated possible sites for RES installations, namely wind turbines and PV arrays. Other energy related data, such as that of water use, energy demand for water desalination and statistics of the island’s touristic activity, which is a major cause for energy demand increase during the hot summer months, were collected.

Furthermore, the study,which is being sponsored by PPC Renewables, the Hellenic Electricity Distribution Network Operator and Hellenic Petroleum,investigates the feasibility for the installation of a standalone energy system powered by wind, solar and batteries, which will be supported by the existing power generation system in a cold reserve mode. The project approaches the decarbonization of power generation as a result of high penetration of RES (90% -95%) and the minimization of the island’s oil dependency. Also, another major objective of the project is the analysis of the current and projected future energy demand of the island (i.e. households, businesses, public spaces, water desalination, boats and road transportation). In short, the project assesses a future realistic scenario of major electrification and decarbonization of energy demand. Designing the island’s integrated RES based energy system has been undertaken with the help of computational tools developed in-house, namely a mixed integer linear programming tool , which aims to minimize the need for electricity storage or the effective battery capacity of the system.

The importance of the Kastellorizo project lies in its pilot role, since the findings of the study and the study approach in terms of analysis, can be applied in several islands in the Mediterranean region and possibly elsewhere, where similar meteorological and energy demand conditions apply.
