This report explores energy efficiency measures for traditional buildings in Ireland, focusing on the Aran Islands, which feature a rich portfolio of historic stone buildings. It highlights the European Union’s (EU) regulations and directives to improve energy efficiency and reduce carbon emissions, as well as Ireland’s national policy framework. Key retrofitting measures discussed in the report aim to improve thermal performance while preserving the external appearance of buildings in compliance with conservation regulations.

This report provides an in-depth assessment of wind energy development potential in Öland. It analyzes existing wind energy plans, technological advancements, land use constraints, and wind resource availability to identify priority areas for future wind power projects. First, the technical, cultural and environmental constraints for deploying wind farms are assessed, and a list of priority areas is defined.

This report presents a first technical and economic assessment of the possibility of introducing hydrogen-fuelled ferries for transporting passengers and vehicles between the islands of Giglio and Giannutri and the mainland.

This report aims to provide an overview of agricultural decarbonisation opportunities in Gotland. Targeted primarily at farmers and technology providers, it focuses on crops and livestock, excluding forestry and fisheries.

This study explores the feasibility of a community wind turbine in Oileán Chléire, Ireland. The project was initiated in 2022 by some members of the local community, who have already obtained a connection assessment from the local Distribution System Operator (DSO).

The Northern Sporades are an archipelago in the Aegean Sea along Greece's east coast, northeast of the island of Euboea. It consists of 24 islands, four permanently inhabited islands: Alonnisos, Skiathos, Skopelos, and Skyros. The islands Skiathos, Skopelos, and Alonnisos (forming the North Sporades archipelago) are interconnected, and Skiathos is also interconnected to the mainland.A 150/20kV substation of Skiathos with 2x40/50 MVA rating capacity is connected to the mainland’s high voltage grid with 30km of 150kV underground and submarine cables.

The European Energy Communities Facility aims to empower and support the development of emerging energy communities across Europe. Small lump sum grants (45.000 euros) will assist at least 140 energy communities in developing and implement solid business plans for their sustainable energy projects. The first call for applications will be launched in June 2025, and a second call will follow in September 2026.

The study assessed the optimal generation sizing to reach 60%, 80% and 95% renewables penetration by 2040. Two different climate years (2015 and 2016) have been assessed in a dispatch model, optimising the OPEX of a system with a fixed installed base combined with an economic model.

This study explores the integration of renewable energy sources, including photovoltaics (PV), wind turbines (WT) and battery energy storage systems (BESS), to improve sustainability, reduce diesel dependency, and optimise costs for both the grid and the desalination plant of the island of Lipari.

The main focus of this report is on mapping the planning and further implementation of the advanced electricity metering infrastructure on the BES islands, which is the basis for the implementation of the smart electricity system.  This report represents the result of the first support activity focusing on smart electricity systems and will be followed by a roadmap for the implementation of optimal solutions. This report is split into four parts.
