Empowering islands with smarter and sustainable energy storage solutions
Discover the projectAbout the project
RESTOR is a transnational research and innovation project aiming to revolutionize how islands and remote communities plan and implement renewable energy storage systems. By combining advanced decision-making tools and local stakeholder engagement, RESTOR will support clean energy transitions across Europe and South America.
Advanced planning models for optimal storage deployment on islands
Accelerating solar and wind integration in remote communities
Supporting fossil-free pathways across diverse island contexts
Four pilot and three follower sites spanning Europe, South America, and the Pacific

Completion
Running from December 2024 to November 2028, RESTOR brings together eight partners from Sweden, Ireland, France, and Brazil to develop and validate a comprehensive energy storage planning framework.
The project focuses on four pilot sites and three follower sites across diverse island and remote communities, each facing unique energy challenges. By tailoring solutions to local contexts, RESTOR aims to create replicable models for clean energy transitions worldwide.
What we aim to achieve
RESTOR pursues six interconnected objectives to deliver a robust, replicable framework for renewable energy storage planning on islands.
Develop a comprehensive MCDA model that integrates technical, economic, environmental, and social criteria to support energy storage planning for island systems.
Collect and analyze energy demand profiles, renewable generation data, and grid characteristics across diverse island contexts to inform storage deployment.
Involve local communities, utilities, and policymakers in co-designing storage solutions through participatory workshops and qualitative context analysis.
Test and validate the RESTOR model across four pilot sites with distinct energy challenges — from Nordic to tropical island settings.
Assess how the model can be transferred to additional islands worldwide, including validation studies in Greece, Fiji, and Fernando de Noronha.
Share findings through open-access publications, a knowledge community, and policy recommendations to accelerate clean energy transitions globally.
How we work
RESTOR is structured around six work packages that take the project from foundational research through case-study validation to global scalability.
Coordination, quality assurance, data management planning, and financial oversight across the consortium.
Building a cross-project knowledge network, annual reporting, and facilitating collaboration between island stakeholders.
Defining use cases, collecting energy data, developing the Multi-Criteria Decision Analysis model, and conducting qualitative context analysis.
Applying the RESTOR model to four pilot sites — Gotland, Aran Islands, La Reunion, and Remanso — each with unique energy contexts.
Finalizing the MCDA model based on case-study feedback, comparative analysis of results, and documenting lessons learned.
Validating the model on new sites (Lesvos, Fiji, Fernando de Noronha) and assessing replicability for islands worldwide.

Pilot & Follower Sites
RESTOR validates its energy storage planning model across four pilot case-studies and three follower sites for validation, spanning diverse island and remote communities worldwide.
Pilot Sites
A group of three small islands off Ireland's west coast (pop. ~850) with 22 buildings already equipped with PV, storage, and monitoring systems via the EU REACT project. Electricity is imported via a sub-sea cable from the mainland. RESTOR evaluates how community-scale storage can reduce cable dependency and increase local energy resilience.
Sweden's largest island (pop. ~60,000) in the Baltic Sea, with significant wind power capacity but limited grid connection to the mainland. RESTOR evaluates battery and hydrogen storage to balance seasonal generation peaks and support the island's goal of becoming fossil-free by 2040.
A volcanic French overseas territory (pop. ~870,000) in the Indian Ocean, targeting energy autonomy by 2030. With abundant solar and emerging ocean energy, La Reunion faces high electricity costs and heavy reliance on imported fossil fuels. RESTOR models optimal storage mixes to stabilize the isolated grid.
A remote community in Bahia state where Xique-Xique village (~400 inhabitants) operates an off-grid solar microgrid with 616 PV panels (243 kWp) and battery storage providing 48-hour autonomy. RESTOR assesses how the planning model can optimise and expand this pioneering system to improve energy reliability for surrounding communities.
Follower Sites
Validation sites where the RESTOR model is tested for transferability and scalability.
A Greek island in the northeastern Aegean where RES expansion has been largely halted due to grid stability issues. The RESTOR model is applied to identify storage solutions that enable further renewable integration while providing economic benefits to the island community.
A small island developing state in the southwest Pacific with autonomous electricity grids on five major islands serving ~925,000 people. Generation fluctuates between 50–60% renewables and 40–50% fossil fuels. RESTOR validates how its model can help plan storage assets to transition outer islands away from diesel dependency.
A UNESCO World Heritage archipelago 350 km off Brazil's coast (pop. ~3,167), currently 90% powered by diesel generators with only 10% from solar. RESTOR validates how its planning model can chart a path to replace diesel with solar-plus-storage on this ecologically sensitive island.
