Ensure the Universal Electricity Access is one of the Sustainable Development Goals approved by the United Nation in the 2030 Agenda. The present work aims to be a response to such call for action we can support as scientific community and as technicians.\\
Off-grid systems represent a solution increasingly appropriate as well as accessible, in economics terms, both for users and operators.
In the present job of Thesis a comprehensive design process is proposed that embraces all the work phases to be implemented starting from a \textit{greenfield} site. Thus, are applied structured methodologies for the needs assessment, key planning step, considering all the best practices suggested by the scientific literature. Besides, potential loads the mini-grid has to feed are evaluated following specific models referred to remote communities. Finally, the optimal sizing of the generation system is performed as well as related costs are detailed. Such process has been tested on a Case Study, provided by the Company NexuS Energy which the author has collaborated with to the Thesis drafting.
Indeed, the path has been approached with the aim to draw up an effective planning strategy which could serve as an assessment tool for private Companies active in the sector, which represent the real economic engine for a roll out of these technologies.
