At present, as energy resources are increasingly scarce, it is necessary to apply a highly efficient savings policy. In this context, it is essential to study and analyze electrical systems, mainly supply systems in production and service facilities. It is important to point out that in peak electricity hours, even the least efficient generating machines have to work, increasing oil consumption per kWh generated; on the other hand, there are great difficulties in transferring power from different generating units to the places where electricity is consumed in those critical hours. Therefore, when the energy demand is not in correspondence with the generation of the generating plants, it is then necessary to interrupt some loads, producing the well-known blackouts and, consequently, the inconvenience and affectations of the users of the electrical service, it is in these cases where the need for electric charge accommodation becomes evident. Therefore, this article aims to propose an application to accommodate loads in industrial systems, through a graphical interface, based on the free software Scilab, which among other things allows load accommodation considering the installation or not of a photovoltaic system. To verify its usefulness, the UEB Pinturas Vitral located in the municipality of San José de las Lajas, Mayabeque Province, Cuba, has 2 work shifts.

Keywords : Accommodate loads; demand control; power quality; industrial systems; Scilab; teaching-learning process.
