Autonomous systems based on the use of renewable energy (RE) have proven suitable for providing energy and sanitation services to isolated communities. However, most of these projects fail due to managerial weaknesses. In these systems, designing an appropriate management model is a key issue for sustainability and it is especially complex if it has to include different RE technologies. This paper is aimed developing a novel management model for RE projects to provide energy and sanitation services able to deal with any kind of technology. Moreover, a new method to evaluate the sustainability is proposed regarding the technical, the economic, the social/ethical, the environmental and the institutional/organizational dimension. In particular, the case study of Pucara (Peru) is presented, in which a RE project with six different technologies was implemented and the integral community management model was designed in 2011. The project sustainability was evaluated in 2013 and results showed the management model has succeeded to strengthen the sustainability of the project, especially in the institutional/organizational aspects.
