The cost of electric power has become one of the most representative expenditures in the industrial environment and other organizations, only after human resources. Currently, seeking the reduction of expenses in processes and operations has become a necessity for survival in the market. Therefore, the optimization of any process is the measurement, only what is measured can be managed and therefore improved. The reduction and good use of energy is not possible without having a reliable source of information; that is why the implementation of a useful monitoring system will indicate the expenses and in what way to proceed in order to establish real opportunities for savings, as well as strategies for their maintenance in different networks. Thus, the following paper is the result of the implementation of an electrical monitoring system for an industry in the region.
