Following an invitation from Greece’s Regulatory Authority for Energy (RAE), IENE through its researcher Alexandros Perellis participated actively in the special event, titled "Non-Interconnected Islands and Innovations in the Electric Market", held on Tuesday, September 10, at “Ioannis Vellidis” Congress Centre in Thessaloniki. Following an invitation from Greece’s Regulatory Authority for Energy (RAE), IENE through its researcher Alexandros Perellis participated actively in the special event, titled "Non-Interconnected Islands and Innovations in the Electric Market", held on Tuesday, September 10, at "Ioannis Vellidis” Congress Centre in Thessaloniki. In his presentation, Mr. Perellis highlighted the problem of high dependence for oil on Greek non-interconnected islands and therefore the very high local electricity generation costs and large CO2 emissions of the autonomous local island systems.
He then presented the case of Kastellorizo island, which was examined in a most recent study of the Institute, entitled, "Energy Transition of the Island of Kastellorizo”. The above Study presents the preliminary design of a large-scale stand-alone microgrid system powered by Solar PV, wind turbines and li-ion battery-based electricity storage systems aiming to substitute the current oil-based energy system. The design is tailormade for both the RES potential of the area and the annual energy needs of the island of Kastellorizo, as forecasted for 2025.
The presentation included the RES and Storage system design methodology and performance assessment, while system optimization techniques, technical recommendations and topology suggestions for the installation of the system were also presented. The presentation followed with the economic assessment of the investment, which was estimated to be very attractive, reducing significantly the full annual local electricity system’s costs and concluded with a summary of the main points of the study.
