Rural electrification projects (REP) in Colombia lack a strong institutional framework. About 5% of the population in Colombia does not have access to electricity service and that hinders their social and economic development. In this paper, we review the recent developments in the topic of rural electrification in Colombia and propose some strategies to ensure the sustainability of the projects implemented in the rural area. The great challenge for Colombia is to have universal access to electricity and in that process are several actions that have been developed and could serve as a model for other countries. The Sustainability strategies presented are validated through a case study.
