It defines opportunities over a long period of time agreements with Federal Wholesale Market of the power and loading. Forecasting statistical models of power systems loading graph, based on the data statistical analysis and use of regressive models for communication of the parameters describing loading graph are developed. By the example of frequency system influence there are errors that cause change of loading it is rendered.
