New microgrid to meet 70% of island’s total requirements


The innovative, hybrid power project stationed on the Greek Island of Tilos will begin operation in February after three years of preparation. 

The Tilos project combines energy production from renewable sources and storage in accumulators. This ensures a constant supply of energy into the main grid, even when renewable energy generation is low.

The project is the island’s first to integrate renewable energy generation and an energy storage system.

The development of the microgrid forms part of efforts to make the island completely independent in terms of power supply.

Tilos meets its energy demand with electricity from neighbouring island Kos. The electricity is supplied to the island via an undersea cable, which is however, vulnerable to faults, especially when seas are rough.

The island will meet 70% of its total energy demand using the new microgrid.

Maria Kamma-Alfieri, mayor at Tilos, said: ”Thanks to this system we could also provide energy to the Kos network. It is a unique project, funded by the European program Horizon 2020 and the population has embraced it”.

The project was given the green light on January 16 2017, with the signing of a power purchase agreement between the Hellenic Electricity Distribution Network Operator and EUNICE Energy Group.

The project falls under the supervision of the University of Piraeus.

The University of Piraeus has also begun hosting summer schools, encouraging students to carry out research on techniques to plan and build hybrid energy systems. The idea is to encourage the population to become enthusiastic about the possibilities of green energy.
