ePLANET project is a Coordination and Support Action cofounded by the European Commission through Horizon 2020 program. ePLANET aims to deploy a new clustering governance for energy transition based on a digital framework to share harmonized information, facilitating the adoption of coordinated energy transition actions by the European public sector. The development of ePLANET is justified to deploy Energy Transition (ET) in public sector, for which the following challenges are targeted: Improving coordination between local authorities and regional governments, Enhancing decision-making process in deployment of ET projects, Providing coherence and consistency to the energy transition measures (ETM) to be implemented, Encouraging the digitalization of measures and plans Enabling an interoperable ecosystem of data and tools, Building capacity of local authorities. All these targeted objectives will give the needed support for the energy transition decision-making process and its practical implementation. The present report outlines the detailed structure and plan for the ePLANET Capacity Building Programme that will be implemented in the framework of WP4. The programme includes a total of 24 capacity building activities (8 per pilot) to be implemented from M20 to M31. Out of the 24 activities, 18 are private and 6 are public. Private activities are designed for representatives of a local authority in the pilot territories (which can be a city, a municipality, or an energy transition facilitator working for the local authority). Public activities, on the other hand, are designed to all stakeholders, including local authorities, regional energy and climate agencies, all energy transition facilitators, students, and citizens as a whole. The capacity building program for each pilot comprises a set of activities including content-focused workshops, webinars and raising awareness sessions on Climate Change attracting a wider audience.
