The negative effect caused by the degradation of nature and its ecosystems by the production of unbridled energy, drives in recent years the reduction of environmental impacts generated by high energy consumption through policies and proposals focused on the generation of rational energy. Although there are international laws and conventions in favor of energy sustainability, backed by international standards for energy management, such as ISO 50001, there is a lack of disclosure of cases of research studies focused on different entities that produce goods and services in countries developing. This paper presents the analysis of the electricity consumption of the University of Unicomfacauca in Popayán-Colombia, which leads to the generation of proposals for savings, energy efficiency and generation of photovoltaic energy for self-consumption; the first phase of the study consists in carrying out the energy inventory of the equipment and facilities; the second phase consists of the diagnosis, load inventory, macro consumption analysis and definition of energy saving and efficiency measures; the third phase involves the implementation of the proposed measures taking into account the cost benefit; the fourth phase, monitoring and evaluation of the measures implemented is carried out. The results show the model for the total monthly and annual electricity consumption, the energy analysis of the electrical system of the specified substations in maximum active power and apparent power, the load index and the electric power consumption; Likewise, the energy analysis of the lighting system and the viability of generating photovoltaic energy for self-consumption.
