The development of any country is linked to supply and conditions of existing infrastructure. The energy input is a high spread in all types of productive activities. In particular, the structure of governance of the energy sector depends on the rules of engagement established by the countries. Search is based on institutional theory to understand the process of evolution of the Brazilian electric sector, centralization that began in the 30s the decentralization of the 90s, as well as changes in the structure of governance. The institutional theory to show that institutions have an important role in economic development, where a set of political institutions and economic efficiency results in lower transaction costs and consequently, in product and factor markets more efficient. In the Brazilian electric sector, the regulatory model is the mechanism by which it maintains the balance of interests of organizations that work in this sector, and this happens from the balance between its internal logic and its external environment, thus providing favorable conditions for the production, transmission and distribution of energy, and for the benefit of society. Consequently, understanding the evolution of the Brazilian electric sector, the decentralization process and training of regulatory agencies, and the resulting structure of governance, it is important. The governance structure of the Brazilian electric sector has undergone several changes over the course of little more than a century, reflecting the institutional thinking globally and nationally each period of its history. The governance of the Brazilian electricity sector currently has a hybrid structure, with decentralized decisions in the sector, with ANEEL responsible for supervision and regulation, and conflict mediation. ANEEL has oversight of state agencies, Consumer Councils, SBDC, CONAMA, MMA, SNRH and ANA, as auxiliary bodies in carrying out their duties, but subject to the interests of the state. The generation, distribution and consumption of electricity are also composed of several agents in order for the state of clarifying the rules for contract officers with different duties and encourage input and participation of private capital in the sector.
