The integration of renewable energy technologies and the consequent reduction in investment costs has led to an increase in the use of distributed energy resources (DER), which has allowed the deployment of more and more microgrids. Despite the many benefits that can be derived from microgrids, they still face many barriers to participating in the electricity industry compared to traditional grids. This paper proposes to address the implications of installing renewable energy in the parish 5 de Agosto, Stone Mine Sector of the city of Esmeraldas, through a technical-economic analysis of the implementation of a microgrid using the HOMER network software. The analysis shows that implementing a microgrid for renewable energy production significantly reduces total costs, unit energy costs and carbon dioxide emissions over the entire project life cycle. Finally, it is concluded that the photovoltaic matrix produces 82.3%, wind turbines 15.3% and the contribution from the grid is 2.45% of the total energy, respectively.  The percentage of renewable energies in the system is 100%.

<p style="text-align: justify;">Este proyecto técnico tiene como finalidad la elaboración de un Modelo de Programación de mantenimiento preventivo y predictivo, el cual sirve a todo el sistema de subtransmisión de CNEL EP Unidad de Negocio Esmeraldas comprendido por las líneas de subtransmisión y Subestaciones. Se realiza un recorrido por las subestaciones y líneas de subtransmisión que comprenden el sistema eléctrico de alta tensión de CNEL EP Unidad de negocio Esmeraldas, con el fin de ver las condiciones en que se encuentran, además se realizó un levantamiento de datos y se contó con información sobre los planes de mantenimiento de CNEL EP U N Esmeraldas. Se diseñan las tareas o actividades idóneas a realizar en cada uno de los equipos y elementos del sistema de subtransmisión, a partir de las normas establecidas. Se elabora una programación de mantenimiento predictivo y preventivo para las líneas de subtransmisión y subestaciones. Esta programación será de mucha utilidad en los futuros mantenimientos del sistema de subtransmisión de CNEL EP Unidad de Negocio Esmeraldas.</p>

The accelerated increase in the demand for energy due to development and population growth involves increasing demands on resources. The diversity of typologies of the metropolis, reference to resources, requests, architectural conditions, infrastructure, or density, make a specific study important. The objective is to determine the most appropriate technology to be installed in the mode of distributed generation with renewable energy sources, the use of the geographic information system and qualitative and quantitative analysis was applied as a methodology. In the work, certain reference resources are identified for the organization process that would allow the selection of the most correct technology for the Santa Ana Canton in the province of Manabí, where the environmental resources that are sustained to make investments taking advantage of other types of clean energy were valued because the resource is the component with the most monumental preponderance, followed by economic conditions; On the other hand, it is detected that points of the environment such as climate change, eutrophication or acidification, are the least incidents, quick to choose technologies.
