Tilos is a Greek island located in the South Aegean Sea. It belongs to the complex of the Dodecanese Islands. There are around 500 permanent residents on Tilos, which is increased by 4 to 5 times during the summer period. The island's main economic field is tourism.

How does the island cover its need for energy? 

The island covers large shares of its electricity needs through local renewable energy systems power generation, a hybrid wind-PV battery station of 1 MW. It is interconnected with the island systems of Kos and Kalymnos. There is a ferry connection to Kos and Rhodes (2 h travel) and also a connection to Piraeus (14 h travel). Transportation locally is mainly by car and bike - there is also a frequent bus connection between the two main villages of Livadia and Megalo Chorio. Recently, the island has embraced clean e-mobility, introducing EV charging points and is moving forward with gradually replacing conventional municipality vehicles. Other uses like heating and cooling for buildings rely on electricity (mostly A/C) and local biomass for heating.

Tilos Island's energy transition

Over the recent years, Tilos island accelerated its clean energy transition at a remarkable pace, enabled by the strong commitment of the local Municipality, the pro-environmental culture and mindset of Tilos citizens, and the implementation locally of innovative demonstration projects, such as the Horizon 2020 TILOS project. By embracing community-scale wind and solar, battery energy storage and advanced energy management and metering, Tilos achieves high shares of renewables in the local electricity sector. At the same time, Tilos extends its efforts to e-mobility and renewable-driven EV charging infrastructure, sustainable water management and energy efficiency in the local public lighting sector.
