Claim:
A power source system for a facility, comprising: a first energy source that provides energy to a microturbine generator system, the first energy source comprising one of natural gas and propane; a first bus line that receives AC power from the microturbine generator system and forwards the AC power to one or more rectifiers; a first switch that deactivates the AC power from the microturbine generator system and activates a secondary AC power source during an interruption of the AC power from the microturbine generator system; a valve that activates a backup source to one or more fuel cell modules during an interruption of the AC power and the secondary AC power source; and a second bus line that receives DC power from the one or more rectifiers and forwards the DC power to the facility and to one or more capacitors, wherein the one or more capacitors hold a charge such that power is maintained during any changeover time period from deactivation of a power source until subsequent activation of another power source occurs.
