The thermoelectric power plants were installed in the country as energetic security, due to our dependence on climatic factors to produce energy. Nowadays, these projects have been working in a continuous mode, hasting the contractual maintenance established by the manufacturers of their generating sets and with all their installed capacity dispatched by the regulating agency. The regulation of energy in Brazil requires compliance with the supply of the contracted capacity, otherwise the energy generating agent may be incurred with nancial sanctions. Give that, the agent of power generation faces the situation of choosing to attend to the energy demand in full capacity or perform their maintenances determined by the manufacturers, handling with the high costs of penalties. Moreover, some power plants have the internal consumption withdrawn from their full generation and are already being penalized, even being a small amount. The Power Quality (PQ) come as an option to maximize the power plant attendance, aiming that all its installed capacity be dedicated to the amount exportation that is compromised with the regulated power generation supply contracts and that may occur some replacement of machines that will be under maintenance. In this regards, it is relevant to understand the impacts in the regulatory area for thermoelectrical power plants in some power generation scenarios as premisse, modeling the technical and economical feasibility for using the PQ to that objective. In addition, a case study of a power plant located in the state of Bahia, which is exposed in their contracts in the regulated environment depending on the problem listed above was presented. In the methodology it has been evaluated some PQ topics and modeling a system of power factor correction that attended technically the power plant treated in the case study. After the technical feasibility, it was performed an economical feasibility analysis of this solution, where have achieved common success. It is expected to check the use of the PQ technologies studied, aiming to favour the maintenance planning and maximize the available power to attend to the generation dispatch in thermo power plants with similar characteristics.
