PowerForecaster is a statistical tool, employing weather data and historical actual load data as input to generate load forecasts on a day-ahead and hourly basis and present the results to the RTOs for each service territory. End users may choose to either use the Load Forecast created by the product, modify the Load Forecast, or enter their own Load Forecast. PowerForecaster can be run several times each morning as part of the day-ahead process and executed each hour with revised weather updates. Historical Load and Forecasted Load data resides in the databases indefinitely.
