MANUEL VILLAVICENCIO ABSTRACT Jigawa State, with a rural population of 85% and 20% of electricity access among other basic services deficiencies, is one of the poorest states of Nigeria The electrification targets of the state were assessed from a decentralized approach. Solar potential, biomass residues and Jatropha Curcas harvest are the main local resources to be considered for power generation. It was found that a fuel diversified strategy, considering local available resources, represent a more feasible and ecological alternative than the current strategy based on increasing on-grid diesel capacity, and also improve security against fuel price volatility and eventual supply contingencies. SUPPORT FOR THE ELABORATION OF THE MASTER PLAN FOR THE JIGAWA STATE ELECTRIFICATION ENGR. MANUEL VILLAVICENCIO ACKNOWLEDGMENTS Special thanks to my family and friends who have been extremely supportive, remarkably enthusiast and uniquely kind to me during my stay in Barcelona. I would like to thank my live girlfriend for her moral support and her understanding regarding to me while spending long working hours in front of the computer. I would like to thank the work team conformed by my professor Enric Velo, my co- director Engr. David Vilar and my team partner and high level assessor PhD. Alejandro Blanco Romero, for their wise supervision and advices on the realization of this project. Finally, I am in debt to all the people that directly or indirectly have helped me in the elaboration of this project.
