Both INSULAE and ISLANDER focus specifically on transforming island energy systems through renewables, storage, and smart control.
REGIONALNA ENERGETSKA AGENCIJA KVARNER
Croatian regional energy agency specializing in island decarbonisation, energy storage, and integrated clean energy planning for coastal communities.
Their core work
Regional Energy Agency Kvarner is a public energy agency based in Rijeka, Croatia, focused on accelerating the clean energy transition in island and coastal communities along the Adriatic. They specialize in developing integrated energy and mobility plans for municipalities, with particular strength in island decarbonisation — combining renewable energy deployment, energy storage, electric mobility, and smart grid solutions. Their practical work centers on translating EU-level energy policy into actionable local implementation plans, helping island communities reduce fossil fuel dependence through tailored investment strategies and community energy models.
What they specialise in
SIMPLA addressed integrated multi-sector planning, while INSULAE and ISLANDER include electric mobility and EV charging alongside energy infrastructure.
INSULAE covers energy storage broadly, while ISLANDER specifies small-scale storage systems, seasonal storage, and heat storage.
INSULAE explicitly addresses local energy communities, big data, and smart control for demand-side management.
ISLANDER introduces seawater district heating and desalination — niche solutions tailored to island and coastal settings.
How they've shifted over time
The agency started with broad municipal energy planning through SIMPLA (2016), which focused on harmonizing sustainable energy and transport plans across sectors. From 2019 onward, their work became sharply focused on island-specific energy challenges — first with INSULAE targeting EU islands' energy storage, renewables, and community energy models, then with ISLANDER diving deeper into decarbonisation technologies like seawater heating, DC grids, and seasonal storage. The trajectory shows a clear specialization from general energy planning toward becoming an island energy transition specialist.
Moving toward highly specialized island and coastal energy solutions — expect future work in marine renewables, community microgrids, and climate-adapted infrastructure for Mediterranean islands.
How they like to work
Always participates as a partner rather than leading consortia, which is typical for regional energy agencies that bring local implementation capacity rather than research leadership. With 58 unique partners across 15 countries from just 3 projects, they operate in large Innovation Action consortia (averaging ~20 partners per project). This makes them an accessible and experienced consortium partner — familiar with large-scale EU project management and comfortable contributing alongside diverse international teams.
Despite only 3 projects, they have built a broad network of 58 partners across 15 countries — a result of participating in large Innovation Action consortia focused on EU island energy systems. Their geographic connections likely span Mediterranean and Atlantic island regions across Europe.
What sets them apart
As a Croatian regional energy agency on the Adriatic coast, they bring direct access to island communities and local authorities in the Kvarner region — a living laboratory for island decarbonisation. Unlike university partners who contribute research, they provide on-the-ground implementation capacity: working with municipalities, managing local action plans, and bridging EU project outputs with real community adoption. For any consortium targeting Mediterranean island energy transitions, they offer both technical knowledge and the local trust needed to make pilot deployments happen.
Highlights from their portfolio
- ISLANDERTheir largest and most recent project (EUR 132,500), tackling advanced island decarbonisation topics including seawater district heating, DC grids, and seasonal storage — signaling their deepening specialization.
- INSULAETheir highest-funded project (EUR 139,925), covering a comprehensive island energy transformation agenda from storage and renewables to bioeconomy and local energy communities.
