Day by day the use of electricity is more important to human activity, in commercial, industrial and residential applications. Electrical Power Business has significantly changed in the last 30 years. A considerable change in the structure and electric power system operation can be seen throughout the world. In spite of an unbundled and competitive electric market, problems of power quality are increasingly significant. Their existence has led to the creation of a regulatory framework for the purpose of monitoring and improving this aspect. In Argentina, power quality control is carried out by penalties for those who break the laws and with rewards for those who respect the normative. Regardless of its psychological effects, preventing power outages presents a vital importance due to its severe effects on economy. Therefore, since it has so many motivating factors, studying and estimating the outage costs has been an attractive and popular field of study in the recent years.
It is necessary to have appropriate means and methods to identify the different types of problems in electrical systems and also to quantify them in monetary values, that is the cost of losses due to power quality issues. The main purpose of this work is to develop a proper mathematical model to be able to reach a conclusion and to make estimations about customer’s outage costs and also to give large power consuming customers an idea about these losses. At this point, it is described a way to find out an almost linear model for this problem. The value of this work is based on in its contribution to the investigations which determine money losses suffered by customers due to the poor quality of the received energy. Such costs, and hence the contribution obtained from this research, could be taken into account in future regulations and/or in investment plans of utilities and by companies that use sensitive equipment. Through this research it is presented a methodology for estimating the cost of power outages to customers in several subcategories of industrial and commercial sectors. The model is applied and validated in a particular case: for the customers of Cordoba Provincial Power Company (EPEC) located in the Zone “Delegation F" of Río Cuarto.
