In Europe, an island in Greece could generate up to 80% of its energy from renewables with the installation of intelligent battery technology, according to grid storage company Younicos.
The projection for the island of Tilos is based a study by Younicos, and adds the technology would “dramatically reduce [the island’s] costs for expensive fossil fuel-based power.”
Tilos, located at the south-eastern part of the Aegean Sea, currently receives its energy supply through an interconnection from the neighbouring island of Kos via the island of Nisiros.
Robert S. Manasse, chief consulting officer of the Younicos Group, commented: “Our results clearly show how an intelligent grid-forming battery system would allow the island to form a renewables-based microgrid.
“Implementing storage will enable Tilos to power itself solely from wind and solar energy, with the existing diesel plant used for back-up only.
Mr Manasse added: “This project is also useful with respect to market development on other islands in the Mediterranean. Greece could significantly reduce its dependence on imported fossils fuels, while creating value at home by utilising its abundant natural resources.”
Clean energy exporter
The study added that the island of Tilos has the potential to become an exporter of clean power, namely wind and solar power.
According to a company statement, the energy storage system can reduce load on the undersea cable, a development between French, Swedish, Italian and Greek companies to connect The Cyclades (a group of Greek islands, southeast of the mainland in the Aegean Sea) to the national grid.
Greece’s independent power transmission operator, ADMIE is also reported to have signed contracts with Greek and international companies to connect the islands of Mykonos, Paros, Tinos and Syros with Greece’s mainland grid.
Younicos is part of the multinational European demonstration and research project, Technology Innovation for the Local Scale, Optimum Integration of Battery Energy Storage (TILOS), which aims to show the potential of local-scale energy storage to serve a multi-purpose role within an island micro grid that is in communication with a main electricity grid.
To achieve this, 15 companies and institutes from participating EU countries will operate an integrated, smart micro grid on Tilos.
