Estudo de caso para migração de um hipotético consumidor de médio porte para o ambiente de contratação livre de energia.

Abstract

Since the reform of the Brazilian electrical sector started in the 90s with the creation of free consumer defined in the Law 9.074, consumers could now buy their electricity from any supplier that is connected to the National Interconnected System and not just by the local agent transmission or distribution. However the transport and connection’s cost remain regulated and linked to the agent that holds the local concession. With the unbundling occurred in this model, was introduced competition in generation and marketing sectors, in theory making the final price of electricity to final consumers cheaper. Thus although at first glance the purchase of energy in this new environment is attractive is very important that before this migration, the potential free consumers understand the rules and procedures and the risks involved in this model. Thus, this paper has the objective to present a detailed analysis and simulations related to the migration of a hypothetical medium-sized company for Free Contracting Environment of energy, identifying advantages and disadvantages between the two contracting environments of electricity provided in the model current electric market. The methodology is based on analysis of annual energy costs if the consumer was in a captive environment in one year and if their costs were in the free environment also for one year.
