| Summary: | The Madden-Julian Oscillation (MJO) is an intraseasonal oscillation (30-90 days) in the tropical atmosphere that influences climate patterns in various regions. For example, in Southeastern South America, the MJO impacts rainfall, especially during the austral summer, with phases that favor extreme rainfall in Uruguay and southern Brazil, affecting the inflows to Uruguay’s hydroelectric reservoirs. The importance of the MJO lies in its predictability, which extends up to five weeks in advance, allowing for the anticipation of its effects. This study compares the country’s optimal energy programming, considering and not considering the effects of MJO. Possible stochastic realizations are simulated, and the optimal energy programming is calculated. In half of the cases, MJO information is considered, while in the other half, it is not. Results indicate that including historical MJO information affects diesel consumption. In particular, when the oscillation is taken into account, the El Niño phase exhibits less extreme behavior and lower variability than when it is not considered. |
