This article develops a method to estimate electricity costs per production units in an industry, based on ISO 50002 and ISA 5.1 and ISA 88.1 standards.Objective. Finding indicators to relate energyconsumption with production levels.Materials and methods. The method consists of eightsteps: definition of objectives, collection of historical data, definition of areas of interest,performance of the census of load, executionof measurement, fieldwork, calculations and results and analysis. It was applied in a liquorindustry in Popayán Colombia, where the electricity cost per product was estimatedassigning 80% of the total consumed to the production area. Results. With the applicationof the method the amount of energy needed to produce a brandy unit in different presentationswas found; in the production area, energyconsumption is fluctuating every month,but its average is 22% of the total invoicedduring the period studied.Conclusions. The theoretical energy estimation has an error of 2.4% compared to the measuring equipment,so the method developed is appropriate for practical implementation.esAcceso abiertoCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráISO 50002Industria eléctricaRecursos energéticosSector energéticoinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAcces
