INSULAE project aims to develop new innovative solutions for decarbonising European islands, which is crucial for achieving climate and energy goals, as well as for improving the quality of life on islands.

The Renewable Energy Community On Linosa (RECOnLi) project on Linosa, Italy, foresees the installation of a photovoltaic (PV) power plant on public land with a capacity of 405 kW, 40 kW installed on the public school rooftop and ten PV systems for private households with a total capacity of 120 kW, as well as a lithium-ion storage system with a capacity of 1.2 MWh and 0.35 MW to ensure a reliable supply of electricity from the PV systems to be installed by 2026.

Pantelleria is an Italian island and commune in the Strait of Sicily in the Mediterranean Sea, 100 kilometres southwest of Sicily and 60 km east of the Tunisian coast. Administratively, Pantelleria commune belongs to the Sicilian province of Trapani. The objective of this study is to evaluate the best solution for a 7MW solar plant at Pantelleria airport, achieving the highest IRR. The study focuses on providing sufficient information on the solution and thus identifies the highest financial savings over a 20-year period, taking into account the specific costs.

In this report, the completed first part of the CETA is first provided in the original Italian language in which it was written. The material can be used as is in the CETA of the islands. It contains the description of the context of the islands, in terms of the geography, economy and demographics, followed by an assessment of the island's current energy system. Due to the high touristic flows, there is a large seasonal variation in the energy consumption, with the highest peaks in July and August.

Syros municipality has been proactive in preparation of mandatory Electric Vehicle Charging Plan in coordination with distribution system operator, HEDNO. The plan has been adopted and it foresees thirty four charging locations on the island. Based on the previously analysed implementation approaches, the municipality has been considering partner collaboration through joint-venture or concession approach.

Samos is a Greek island located in the eastern Aegean Sea, south of Chios, north of Patmos, and the Dodecanese, and off the coast of western Turkey, from which it is separated by the 1.6- kilometre-wide Mycale Strait.

In 2020, Samos developed its Clean Energy Transition Agenda (CETA), following the guidelines of the Clean energy for EU islands secretariat. The CETA is a strategic roadmap that sets out the paths that the energy transition in Samos will follow, to be jointly implemented by the local community and the stakeholders.

Thira applied with the project Energy Upgrades in the Port Infrastructure of Thira for the second call for technical assistance from the Clean energy for EU islands secretariat in April 2022. A Scope Definition meeting took place on 31 May 2022 between DAFNI, Protasis and the Islands secretariat to agree on the final scope of the project and define the tasks. This report is the final deliverable of the project.

This engagement guide aims to provide island transition teams with tips, guidance, and inspiration on how to involve, liaise, and include stakeholders in all stages of the clean energy transition process. Effectively engaging with the relevant actors that could be affected by the transition is a key for its success. This prominently involves the local stakeholders on the island, but also regional, national, and European organisations.

A clear and supporting legal and regulatory framework is a main building block of enabling and accelerating energy transition on EU islands. In the past two years the Clean energy for EU islands secretariat has been engaging with local, regional and national stakeholders in member states with the inhabited islands to understand existing regulatory framework, barriers to clean energy transition of the islands and to together with stakeholders propose recommendations for overcoming them.

In the past two years, we have been collaborating with member states and island stakeholders to better understand barriers and opportunities to clean energy transition on the EU islands. Grid constrains are seen as one of the key barriers. While DSOs have a role to ensure security of supply, together with policy markers and regulators they need to find a way to prepare for decarbonisation of islands. Electricity grids need to be upgraded and more flexible to integrate increased share of RES while keeping quality and security of supply.
