  • Method and system to calculate a demand for energy
    Patent number: 7406364
    Abstract: A method to calculate energy demand in an energy generation, transmission and distribution network including one or more power plants based on different energy source types including renewable energy, a communications system and one or more local consumption metering units. A customer demand profile for one or more customers is provided. A customer-specified proportion of power demand to be supplied from a given energy source type is registered. A total predicted energy demand dependent is calculated in part on an accumulated demand for the given energy source type.
