The Islands Marketplace

The aim of the Islands Marketplace is to bring island communities, project developers, technology providers, investors and financiers together to support the implementation of clean energy projects in islands. The Clean energy for EU islands secretariat will facilitate the matchmaking of the interested parties.

How to engage with the Islands Marketplace:

Island stakeholders are invited to submit their investment projects. The Clean energy for EU islands secretariat marketplace team will then support islands to get in contact with financial institutions and technology providers to discuss the technology and financing of the project.

Fill out this intake form and send it to

Please note that for a project be considered in the EU Islands Marketplace, island stakeholders/ project developers have to provide as much information as possible, in a way that it is clearly understandable and analysable by the secretariat team, as well as by the investors and technology providers. The type of information required is the following:

  • Project description (details of your project, relevant background, expected timeline, type of technology, maturity level, etc.)

  • Expected impacts (renewable energy production/energy savings, avoided emissions, jobs creation, etc.)

  • Financial aspects (investment type, business model, CAPEX, payback time, internal rate of return, etc.)

Please keep in mind that our matchmaking service does not provide any funding support. The technical support is limited to guidance on how to improve your project’s content. Projects selected will be showcased and, when feasible, matched with investors and technology providers.


Why is this for you?

Through the EU Islands Marketplace:

  • Island’s stakeholders have the possibility develop their projects by connecting with leading clean energy technology providers and front-runners ESG (Environmental, Social and Governance) investors;

  • Investors have the opportunity to increase their pipeline of potential investments;

  • Technology providers have the opportunity to increase their client list through potential sales of technological solutions.

EU Green Deal funding

The European Green Deal is a strategy tool for achieving carbon neutrality and fighting climate change in the EU. The aim of the Green Deal is to turn climate challenges into an opportunity, and to support the energy transition all over Europe. 

Organizations working in the field of climate change, environment and energy can follow the Green Deal action plan and adapt their strategies to the Territorial Just Transition Plans, which will be produced by each EU country through the Just Transition Mechanism



Just Transition Platform

The Just Transition Platform aims to assist EU countries and regions to unlock the support available through the Just Transition Mechanism - financial support and technical assistance which will mobilise at least €100 billion over the period 2021-2027 in the most affected regions.

This platform will provide a single access point for support and knowledge related to the just transition including funding opportunities, relevant regulatory updates and sector specific initiatives.



NESOI - EU Islands Facility

NESOI is a Horizon2020 project aiming to financially support the development of 60 clean energy projects on EU islands by 2023. The project finances technical assistance (not project implementation) to local authorities, with up to 60 000 EUR per grant. It further provides capacity-building and fund matching support.
