Abstract:
A method of operating a customer side electrical power management system, the method comprising the steps of:receiving electric power from a public electric utility via at least one phase line or wire, and thereafter distributing the received electric power toward at least one load at a customer location;providing at least one hydrocarbon-powered fuel cell at the customer location, the at least one hydrocarbon-powered fuel cell receiving hydrocarbon fuel and transforming the hydrocarbon fuel into electric power to be directed to the load;providing a threshold level setting circuit at the customer location, the threshold level setting circuit allowing a customer to set a maximum power level of power from the utility that the customer wishes to receive and pay for;determining when the amount of power being received by the customer from the utility reaches the maximum power level; andcausing all additional power required by the customer that is above the level to be generated by the at least one fuel cell to be directed from the at least one fuel cell to the load.
