1. A method for creating a utility demand forecast model for weather parameters, the method comprising: receiving, by one or more processors, a plurality of utility parameter values, wherein each received utility parameter value corresponds to a weather parameter value; determining, by one or more processors, that a range of weather parameter values lacks a sufficient amount of corresponding received utility parameter values; determining, by one or more processors, one or more utility parameter values that corresponds to the range of weather parameter values; and creating, by one or more processors, a model which correlates the received and the determined utility parameter values with corresponding weather parameters values.
