30 for 2030

The Aeolian Archipelago is in the southern Tyrrhenian Sea. It comprises seven islands, six under the Municipality of Lipari (Lipari itself, Vulcano, Panarea, Stromboli, Alicudi and Filicudi). The differences between the islands and the distance between them and from the mainland determine a mosaic of issues: complexity in energy supply, high costs and fossil-based transports. The whole archipelago is non-interconnected between the mainland and among him. The management of the electric grid and the energy production are handled by private actors (S.E.L. srl in Lipari) and ENEL S.p.A.

Arranmore (Árainn Mhór) aims to achieve sustainability and energy conservation as a result of our participation in the 30 for 2023 call by the Clean energy for EU islands secretariat.

The current grid is under-dimensioned and outdated, with no local energy production because of that, and the landscape preservation regulation.Hven's vision is to mitigate those obstacles, refurbish our grid and produce enough power on the island without altering the landscape.

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 2020. Almost 60 % of the energy comes from renewable sources. Private housing is the sector that uses the 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.As part of the 30 for 2030 call the following activities are planned: The first activity involves conducting a feasibility study for upgrading or replacing two old windmills.

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.
