Abstract
The energy transition to renewable energy in a democratic way is directly connected to the development of energy communities and community microgrids. Los Molinos del Rio Aguas (LMRA), an ecological community in the south of Spain, offers a promising case study for an off-grid community-owned microgrid. In this paper, the interconnection of autonomous solar home systems is proposed with the addition of community assets in order to create an off-grid community microgrid that is financially beneficial for the community. Based on this scenario, a Local Energy Market (LEM) based on Distributed Ledger (DL) technologies is implemented in order to foster the energy exchange and contribute to the social welfare of the community. The results provide a win-win scenario for the community and provides an example of an off-grid community microgrid in combination with a LEM that takes into consideration the social aspect of the community.

Summary
A challenge and opportunity of the energy transition to renewable energy is the participation of citizens in both the production and ownership of renewable energy assets. Market Directive (EMD) [3] provide new opportunities for the activities of individual and Collective Self-Consumption (CSC) as well as for Renewable Energy Communities (RECs) and Citizen Energy Communities (CECs). These concepts provide the framework for citizens to collectively participate in the energy system and give the chance for a new type of initiatives to rise. Thereby, citizens can use this new legal framework in order to participate in the energy market, contributing to an increased decentralized renewable energy production and consumption (prosumption). LEMs offer a platform to exchange energy locally [4]. An extended review on LEMs [5]
