Abstract: In the Nineties, the Brazilian government changed the model of the energy sector, in order to make this sector more competitive and efficient. However in 2001 there was rationing of energy. Consequently, the Brazilian government realized that the energy sector should be adjust urgently to provide more security to all society and to expand of the energy sector. The main change introduced was the duty imposed to the energy distributor company to contract 100% of its demands of energy. In addition, the government has forbidden the free negotiation between energy distributor company and Generators Companies. Therefore, most of all purchase of energy must occur in auctions regulated by the Brazilian government. This work presents a model of optimization and simulation for purchasing energy, a tool for defining the optimum quantity of energy to be acquired by the energy distributor Ampla Energia e Serviços S.A. in the main auction occurred in December 2004. Besides, the present work analysis the performance of the model, comparing its results with the real data of purchasing of energy by Ampla in the auctions occurred in 2005 and 2006.
