Résumé:
There is a major concern of government agencies in maintaining the reliability of the
Brazilian system of power generation due to the fact 80% of this energy is arising from
hydroelectric power plants, of which 50% have over twenty years of operation. The
repowering is a practice that aims to extend the life of hydro, while seeking to rescue
the reliability and increase the potency of the plant. Guidelines and actions for technical
evaluation of a repowering will be presented, because, due to already exist many
repotenciados hydro, it is possible to establish a methodology that addresses the most
important aspects of this practice. And describe the development process of repowering
the hydroelectric generating units Paulo Afonso II, aspects of repowering these
generators, highlighting the methodology, addressing the use of more technologically
efficient materials and the results are discussed.
