Monitoring Electric-Load Forecasts

A program that compares substation summer peak-load forecasts with actual early summer loads which have been adjusted to normal summer peak weather conditions is described. The comparsion shows which forecasts appear low relative to the adjusted early summer loads. Used with substation capability, the results show which substations will become critically loaded sooner than present forecasts indicate. The advantage gained from the method is that necessary equipment changes can be made in a more orderly manner.
