ABSTRACT: This deliverable presents the approach implemented to perform a stakeholder analysis and to produce the TradeRES’ stakeholder engagement plan. It includes the description of the tools used for the stakeholder engagement, namely the webinars, tutorials, experiments and surveys. Before establishing the engagement plan, the identification and prioritization of the relevant stakeholders at the European and national levels are performed. To support this step, a stakeholder mapping approach is followed by clustering each target group into the following categories: “Key player”, “Meet their needs”, “Keep informed” and “Monitor”. This classification takes into account the level of interest and influence of each stakeholder in the project. The communications between the consortium and the stakeholders as well as the preferable channels for these communications are also presented. The engagement plan includes a description of the communication tools, objective, frequency and expected contribution of the different stakeholders. The project comprises different stakeholders to follow closely the work developed providing feedback on the modelling methodology and scope, on market design choices, and on our research results. The stakeholders’ knowledge has been effectively involved since the beginning of the project, namely in activities related to construct reference energy systems for 2030, and their role will be crucial during the iterative process of shaping market designs and testing as well as validating the newly developed open-access market tools.
