A customer side power management system including at least one auxiliary fuel cell(s) source is provided. When the power derived from the electric utility reaches a predetermined threshold level, all remaining power needed to supply the customer's loads is obtained from the at least one hydrocarbon powered fuel cell which is/are located within the customer's facility. In such a manner, high peak demand utility charges are avoided by the customer, and the simple cost effective power generation from the fuel cell is provided.

[ I claim:] [1.] A customer side electrical power management system comprising:a main distribution panel, located at a customer location, for receiving electric power from a public electric utility via a plurality of phase lines or wires, said distribution panel for thereafter distributing the received electric power toward a plurality of loads at the customer location;at least one hydrocarbon-powered fuel cell located at the customer location that receives hydrocarbon fuel and transforms the hydrocarbon fuel into electric power to be directed to said loads;a threshold level setting circuit located at the customer location for allowing the customer to set a maximum power level of power from said utility that the customer wishes to receive and pay for, in order to reduce peak demand charges;a comparator for determining when the amount of power being received by the customer from said utility reaches said maximum power level; andmeans for causing all additional power required by the customer that is above said level to be generated by said at least one fuel cell and to be directed from said at least one fuel cell to said loads.
