1. A method for optimizing the use of electric energy by a facility comprising a plurality of energy assets, the method comprising:

  • modeling, using a computer, the usage of electric energy by the facility, by creating a dynamic simulation model of the plurality of energy assets of the facility;

    wherein the dynamic simulation model of the facility comprises a computation of thermodynamics properties of the facility, andwherein the dynamic simulation model is adaptive to physical changes in the facility based on a parametric estimation;

    calculating, sing the computer, a customer baseline (“

    CBL”

    ) based on the dynamic simulation model, wherein the CBL is predictive of energy consumption of the facility as a function of time;

    storing the dynamic simulation model in the computer;

    determining, using the computer, a plan for controlling the operation of at least one of the plurality of energy assets to reduce an energy provider'"'"'s overall charge to the facility for electric energy, or to provide a revenue source to the facility, the determining being done at least on the basis of the dynamic simulation model, the CBL, and variations in the forecast wholesale electricity price of electric energy in the wholesale market during a defined time period;

    generating, using the computer, control signals based on the plan from data derived from the computer; and

    controlling, using the generated control signals, at least one of the plurality of energy assets so that operation of the facility conforms to the plan.
