Rural electrification rate (RER) in Africa is still low to date. Several countries in Sub-Saharan Africa have tried to address this problem using conventional single-phase two-wire or three-phase three-wire systems, however at large costs due to the nature of dispersed rural load centers, low load demand, and low population density. Another solution of off-grid generation creates associated health problems. Therefore, this paper undertakes a review of a single wire earth return (SWER) network as a RER improvement solution. The paper undertakes intensive literature review to elucidate challenges and solutions to the implementation of SWER technology. Advantages of SWER technology discussed make it the choice for RER improvement in Sub-Saharan African countries. After that, a case study is selected in rural Tanzania, and a preliminary SWER network design is undertaken.

“…A continuación, se analizan publicaciones que se centran en la dimensión institucional; es decir, que evalúan el funcionamiento de los planes y proyectos en cuanto al papel de las instituciones público-privadas promotoras. En este sentido, en los últimos años se ha venido insistiendo que la electrificación rural debe ser promovida por los gobiernos, pero sin que éstos interfieran una vez iniciada, para dar el impulso inicial y que luego el mercado asegure la continuidad de las iniciativas (Rudnick et al, 2014).…”

Evaluación de planes de electrificación rural y propuesta de planificación con criterios técnicos y sociales

Energy access allows to improve population life quality, specifically in terms of food, education and health. Currently, 10% of the world population does not have electricity. 85% of this population is mainly concentrated in rural areas of developing countries. In order to increase electricity access, the national interconnected grid can be extended or, also, isolated systems can be implemented. In particular, systems based on the use of renewable energies are an appropriate option for the most remote communities, since they reduce dependencies on external resources and fossil fuels. Rural electrification planning consists in defining the strategies to be used to satisfy the energy needs of the population without electricity, regarding the design of projects, prioritizing and ordering their execution in time. In many countries, different rural electrification plans have been implemented at a regional and local scale, but they have not always been successful mainly because of the standardization in the design of systems, instead of the detailed analysis of the specific requirements of each population. In this context, this doctoral thesis aims to analyse rural electrification plans and develop a planning proposal at regional scale, which considers the particularities of each community, in the design of projects and their prioritization. In a region of a developing country with several communities without electricity, this proposal would be the guide for electrification promoters throughout the whole decision-making process to select the most appropriate electrification system to be implemented in each community and prioritizing the communities to be electrified, considering technical and social aspects. For the definition of an appropriate planning proposal, it is necessary to consider the key aspects that condition and/or guarantee the sustainability of projects. Hence, this work carries out an evaluation of different rural electrification project plans that have already been implemented, in order to identify and extract the lessons learned and, thus, consider them in the implementation of future plans. Based on the results of the evaluation, the planning proposal is defined, which consists in 3 stages. In stage 1, the initial evaluations are carried out to compile the information (socioeconomic, energy and technical) at regional scale. In stage 2, a definition of projects is performed, where different electrification technologies are compared for each community. Finally, in stage 3, the prioritization of projects is realized, where a hierarchical order of communities is sought from where to start the implementation, considering technical and social criteria. The planning proposal is validated through its application to a real case study, called the Solar communities network (RECOMSOL), which covers 8 rural communities in Chiapas (Mexico) and is promoted by the Chiapas University of Sciences and Arts (UNICACH). Thus, the proposal is demonstrated adequate to implement rural electrification plans at a regional and local scale in developing countries, since it allows the promoters to guide and interact throughout the whole decision process in a clear and systematized way, obtaining results validated by the promoters of the systems. El acceso a la energía permite mejorar la calidad de vida de las personas, específicamente en la alimentación, la educación y la salud. Actualmente, el 10% de la población mundial no tiene electricidad. El 85% de esta población, se concentra principalmente en zonas rurales de países en vías de desarrollo. Para aumentar el acceso a la electricidad, se puede extender la red interconectada nacional o, también, implementar sistemas aislados. En concreto, los sistemas basados en el uso de energías renovables son una opción adecuada para las comunidades más remotas, ya que disminuyen la dependencia de recursos externos y combustibles fósiles. La planificación de la electrificación rural consiste en definir las estrategias a utilizar para satisfacer las necesidades energéticas de la población sin electricidad, en cuanto al diseño de proyectos, priorizar y ordenar su ejecución en el tiempo. En muchos países se han implementado diferentes planes de electrificación rural a escala regional y local, pero no siempre han resultado exitosos debido principalmente a la estandarización en el diseño de los sistemas, en vez del análisis detallado de los requerimientos específicos de cada población. En este contexto, esta tesis doctoral tiene el objetivo de analizar planes de electrificación rural y desarrollar una propuesta de planificación a escala regional, que considere las particularidades de cada comunidad, en el diseño de proyectos y en su priorización. En una región de un país en desarrollo con varias comunidades sin electricidad, esta propuesta sería la guía para los promotores de la electrificación en todo el proceso de toma de decisiones para seleccionar el sistema de electrificación más adecuado a implementar en cada comunidad y priorizando las comunidades a electrificar, considerando aspectos técnicos y sociales. Para definir la propuesta de planificación adecuada, es necesario considerar los aspectos clave que condicionan y/o garantizan la sostenibilidad de los proyectos. Así, este trabajo realiza una evaluación de diferentes planes de proyectos de electrificación rural que ya han sido implementados, con el propósito de identificar y extraer las lecciones aprendidas y, así, considerarlas en la implementación de futuros planes. A partir de los resultados de la evaluación, se define la propuesta de planificación, que consta de 3 etapas. En la etapa 1, se realizan las evaluaciones iniciales para recopilar la información (socioeconómica, energética y técnica) a escala regional. En la etapa 2, se procede con una definición de proyectos, donde se comparan distintas tecnologías de electrificación para cada comunidad. Por último, en la etapa 3, se realiza la priorización de proyectos, donde se busca un orden jerarquizado de comunidades por dónde empezar la implementación, considerando criterios técnicos y sociales. La propuesta de planificación se valida mediante su aplicación a un caso de estudio real, denominado Red de comunidades solares de Chiapas (RECOMSOL), que cubre a 8 comunidades rurales de Chiapas (México) y que está impulsado por la Universidad de Ciencias y Artes de Chiapas (UNICACH). Así, se demuestra que la propuesta de planificación es adecuada para implementar planes de electrificación rural a escala regional y local en países en desarrollo, ya que permite guiar e interactuar a los promotores en todo el proceso de decisión de forma clara y sistematizada, obteniendo resultados validados por los propios promotores de los sistemas.
