The proposal starts with the main potential causes of production cost differences at different hours of the day and months of the year: variations in short-term marginal costs, differences in loss indices, elevation of the tailrace of hydroelectric plants, and inflexible production during the early morning hours. In this stage, the potential impact of each of these possible sources of cost variations is estimated.
Next, a methodology for applying existing tools is developed with the aim of obtaining hourly and seasonal signals for energy, based on marginal costs, incorporating all items identified as relevant in the first stage that are feasible for consideration within the current possibilities of system modeling. The methodology is being evaluated with a view to its possible incorporation into the tariff realignment process within the scope of the periodic tariff review.
