Abstract

A method and system is provided for determining and optimizing electric transfer capacities of electric power system facilities. A processor receives and stores information that is used to compute the quantity of electric power that can flow through one or more electric power facilities. A capability datastore and an external factors datastore communicate with the processor and with each other. The capability datastore computes and stores the electrical transfer capability as a function time duration and at any given point in time while the external factors datastore determines a plurality of variables which affect the electrical transfer capabilities. A resource manager, connected to the processor, allocates resources by optimizing and correlating the electrical transfer capabilities with the plurality of variables, to generate an electrical transfer capacity rating for the one or more electric power facilities as a function of time duration and at any given point in time.
