The main load centers in the province of Manabí are far between 120 and 400 km from hydroelectric forming the basis of the generation system, consequently resulting in a significant amount of losses in transmission and distribution. Currently many settlements in rural areas of the province are affected by irregularities and poor quality of electricity service. The paper presents an analysis of the quality of electricity service in isolated areas of the municipality Chone and proposes solutions that can improve service quality, through sustainable energy planning at the expense of indigenous resources of the territory. Keywords: Service quality, energy efficiency, rural electrification grid extension, photovoltaic systems. 1. Introduction One of the most used in industrial, commercial, services and that has allowed the development of technologies is electric power, which is one of the ways that more advantages and comfort bring human beings today, resources without But is a resource that must be generated on demand in coming to the load centers where the supply and quality can be controlled at the time being used sites. Of all forms of perhaps the most polluting and degrading the environment human activity is on the management of fossil energy resources: extraction, production, transportation and consumption. Most of the energy used in the world comes from the so-called "fossil fuels", which constitute about 80% of primary energy consumption worldwide. Efficiency and saving energy resources are one of the ways to achieve stable power supply and quality service. Now of a need that the power supply system are reliable and in some third world countries there are several factors that prevent energy reaches the user with the required quality. According to the United Nations Program for Development (UNPD), currently 2 billion people lack access to electricity services, billion use uneconomical sources (dry cell batteries, candles, Research Article e-ISSN 2455-4286 Open Access
