Abstract: 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.
