In order to mitigate the climate changes effects, the European Union established several funds and initiatives for the energy transition, one of these is the Clean Energy For EU islands. This kind of initiatives requires the developing of a transition agenda, encouraging a collaboration between the European Secretariat, the technical team, the stakeholders and the local communities. One of the greatest challenges of these types of collaborations is the settling of the energy system's objectives between the stakeholders and the technical team, and usually this requires several meetings between the two parts. In this thesis work, some tools for the scenario planning have been developed to make the scheduling of the scenarios easier, including their presentation.
