The Island of Pašman is located in the Zadar County, it is 21.3 km long, 4.3 km wide at its widest, 63 km2 in surface and is located directly along the mainland, from which it is separated by a channel, 2-5 km wide. Characteristics of the climate are hot and dry summers and mild and wet winters. The island belongs to the Mediterranean climate type. In January/February, the average temperature is 6.5-7 °C, while in July /August the average is 24-24.5 °C. Average insolation is 2,490 hours (county average), annual average precipitation is 800-900 mm.

Lesvos has an autonomous electrical system. It is not interconnected with the mainland and its annual peak demand has been on a slight increase over the last four years reaching 63,25 MW in 2022. The island is connected to Megalonisi with a power transmission capacity of 11,5 MVA through various types of conductors.In terms of installed capacity, Lesvos showcases a diverse portfolio, of five wind farms (WFs) with a total capacity of 13,95 MW, 133 photovoltaic stations (PVs), with a total capacity of 8,838 MW and 102.6 MW of thermal units in the local power station (LPS).

Megisti is the easternmost and most isolated region of Greece, located 520 km from the mainland. The island is neither electrically interconnected, nor are there any relevant national plans for the future. With no RES installed as of today, all electricity is currently generated by a diesel thermal power station. Despite Megisti’s small size, electricity demand shows very high seasonality, mostly due to the large diaspora.

The electrical system of Psara has for a long time been a wind energy net exporter through its interconnection to the island of Chios. However, the installed intermittent wind capacity can neither cover the island’s electricity needs on a 24/7 basis, nor provide resilience to the local grid or security of supply, in case of interconnection interruption. In such an event, critical infrastructure (water production and distribution systems, telecommunications, Rural Clinic, etc.) could remain out of service.

The total energy use in Öland was approximately 350 GWh for the year 2020. Almost 60 % of the energy comes from renewable sources. Private housing is the sector that uses most energy, with transport as the second largest. Wind power has been established for a long time on the island and many are soon facing the end of their technical lifespan and are to be replaced by new more efficient ones.

Fejø is integrated into the Danish electrical grid but lacks connectivity to the natural gas network. Energy consumption predominantly relies on gasoline, fuel oil, and wood.The island's vision is twofold: achieving a complete shift to renewable energy sources for all energy needs and establishing the island as a self-sufficient energy producer.Watch this statement by citizens of Fejø to learn more about their motivation and the secretariat's work. 

The Island of La Graciosa has, for 50 years and until today, an energy and water supply completely dependent on the island of Lanzarote, located 1.5 km away. All the energy and drinking water supplied to La Graciosa is channelled through underwater cables and pipes and comes from processes that, approximately 90%, are derived from the burning of fossil fuels.

Venø is a Danish island  and the only island in the municipality of Struer (Central Denmark Region). Distance to the mainland is 256 m. The island is served by municipality owned ferry-service with 44 daily departures. Venø has 80 resident houses and 60 holiday cottages. The main economic activities are a boarding school, farming, seafood production facility, few active craftsmen and tourism.In mid-2022, the local citizen association began an energy transition project sponsored by the NESOI, Struer Municipality and the energy supplier.

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.

The Island of San Pietro is located in the southwest of Sardinia, and about 5,950 inhabitants live on 51 square kilometres, characterised by pristine beaches and breathtaking scenery. In August 2019, up to 50,000 tourists reached this ‘paradise’. A relevant economic part rests on the sustainable fishing of bluefin tuna, unique for its culinary and healthy properties. On the island, the tuna is also processed and prepared for shipments around the world.
