Electric power load in Brazil: view on the long-term forecasting models

Research method Simulations are carried out to estimate the cost of deviation, in order to assess the impact of the load forecast on the system. Main findings As a result, there is an urgent need to clarify forecasting methods and strategies; to avoid, by the sector agents, justifications that optimistic forecasts are necessary as security measures. Implications for theory and practice There are evidence that small improvements in forecasting models imply significant cost reductions.
