RESUMO

This dissertation addresses the pricing of electrical energy contracts in the Brazilian market, a topic whose difficulty stems mainly because it is a very recent market without a long historic of prices. It offers a contribution situated in two points: the pricing of purchase and sell contracts of inflexible electrical energy (options and forwards) in the Free Hiring Environment; the impact of charges and taxes on the profitability of these contracts. Different types of contracts have been used in the free market of energy. The inflexible contracts (options and forwards) were selected because they are most often practiced in the market. The binomial latisse model is the main tool of pricing used in this work. This technique is well known in the financial market for the option contracts pricing. Here it will be used to ca1culate the expected value of Spot Price - PLD, expected value of the Service System Cost - ESS, the expected value of a forward contract and the expected value of an option contract. In this work context, pricing includes the determination of benefit measures and unit risk (R$/MWh) because hiring decisions are instructed by the negotiated price of energy (R$/ MWh), than the total financial volume of the contract (R$). In addition to the crude benefit evaluation, it is also made an estimation of charges and taxes impact on the contract. It will be presented the main taxes and charges that focus on purchase and sell of energy. Among the charges and taxes owed by consumers, the ESS will be evaluated as a risk asset because of its difficulty of prediction as it is set monthly by the CCEE and presents considerable volatility
