The insertion of the energy storage systems is a global trend observed in the energy diversification scenario of several countries in the world. Considering the predominance of centralized hydroelectric generation in the brazilian electric matrix, Pumped Storage Hydroelectric Plans tend to be used within the National Interconnected System (SIN). However, such insertion process must consider the new changes in the regulatory framework arising from Brazilian regulatory policies for the sector. The selection of these policies must consider several and several dimensions. In addition, the chosen policy must consider a Regulatory Impact Analysis for its own. The main objective of this dissertation is to propose a model for the selection and evaluation of these policies, using a Regulatory Impact Analysis (RIA) process, with the aid of multicriteria decision making methods (MCDM). The defined model was proposed in six stages: definition of the regulatory problem; determination of the regulatory framework; mapping of action alternatives; benefit-cost analysis with the AHP method; selection of preferred policy with the fuzzyTOPSIS method and monitoring and evaluation of this policy. The modeling was applied to the following five policies: creating a capacity market; creation of a flexibility market; implementation of a multi-attribute auction; implementation of a capacity auction; and adoption of an incentive policy. The policies were compared with some references, confirming the applicability of the methodology and indicating the development of the proposed model, gaps in the literature regarding the applications of multicriteria for energy.
