The Brazilian Market of Electrical Energy has not yet found a stable market and price model that ensues the feasibility and makes attractive a self-sustained investment for the expansion of electrical energy generation. Researching the current generation dispatch and spot price model, we show that it is ineffective to attract investments because the model is myopic, since the range of critical system states that is foreseen at the current state is not significant until the system is already too degraded. Stemming from this conclusion, we develop three alternative models, modifying the dispatch model objective and the price formation rule. These alternative models are tuned to make the investments in generation expansion feasible and attractive. The models are compared regarding their value to the investor and the cost to the system and to the consumer. A complete market allows the economic agents to freely allocate their resources and requirements whenever they are available and/or required. A complete market also allows conditional settlement, i.e., to condition the resource availability and/or requirement to a particular market state (price). These features are realized by financial derivatives, in the, so called, futures market. We present a conceptual analysis of the electrical energy s future market, pointing the differences to other commodities future markets that are due to economical unfeasibility of storing electricity. We also present an equilibrium model for the forward electrical energy contracts.
