CVA GOVERNANCE METHODOLOGY WITH RISK ANALYSIS CONSIDERING STOCHASTIC EVENTS
The development of simulation models, that realistically represent the regulatory/ commercial environment in which the company is inserted, is necessary to understand the behavior of some variables needed for decision making. In particular, the financial impact on the “A” Parcel Variation Account (Conta de Variação de Itens da Parcela “A” – CVA) has shown significant values for the distributors, mainly due to the increased participation of availability contracts in their portfolios and the systemic conditions presented in recent years, with a significant increase in the dispatch of thermal power plants. In some months, CVA values even exceed the company's remuneration through Parcel “B”. Based on this understanding, this work aims to develop a methodology and tool for the simulation and projection of the CVA in different accounting periods (tariff year, calendar year, month, day and hour) and for different scenarios of systemic conditions, with the calculation of risk metrics and estimating events in the short term market (MCP). To do this, a survey will initially be conducted to identify the entire accounting flow and the tariff bases used by ANEEL, in order to identify the factors involved and perform a mathematical modeling of the tariff calculation system. In sequence, after such files are obtained, through the responsible agents, related to a distribution system operator, an import and interpretation structure is created, resulting in a database that will feed the calculation engine that will carry out the projection of costs associated with CVA.
