1. A method for generating a resultant model for a particular generation or transmission power system, the method comprising the steps of:
- receiving scenario parameters related to the power system;
generating a plurality of scenarios and probabilities representing cost solutions for operating said power system given said scenario parameters;
optimizing each of said plurality of scenario for least cost solutions; and
generating the resultant model that identifies expected values within said power system based on the optimization step and that is associated with said scenarios and their probabilities.

Abstract
A system for generating a resultant model for a particular generation or transmission power system is described, illustrated and claimed. The system involves a new and novel method that combines scenarios and their probabilities to estimate the areas of possible congestion, the expected values of congestion contracts, locational marginal prices, and scenario specific generation and transmission expansion plans as well as other relevant outcomes. One embodiment of the present invention is a model that develops multiple generation and transmission scenarios.
