A power system is designed for providing reliable electrical power to a telecommunications facility and/or associated devices. The system includes a DC bus adapted to receive electrical power from a primary energy source. A switch is provided for switching from the primary energy source to a secondary energy source. Additionally, the system includes one or more capacitors electrically connected into the DC bus. The one or more capacitors hold a charge so that power is maintained to the DC bus as a switch is made from the primary energy source to the secondary energy source.

8. The power source system of claim 1 , further comprising a sensing control mechanism that opens one power source and closes another power source, as instructed.
9. A valve and switching system that provides power to a facility, comprising:
a primary fuel valve that activates and deactivates flow of a primary fuel source to one or more microturbine generators;
a secondary fuel valve that activates flow of a secondary fuel source to the one or more microturbine generators during an interruption of the primary fuel source;
a switch that activates flow of power from an electrical utility source during an interruption of power from the one or more microturbine generators;
a bus line that provides AC power from the electrical utility source and the one or more microturbine generators to one or more rectifiers, wherein the one or more rectifiers provide DC power to the facility;
a valve that activates and deactivates flow of a gaseous fuel source to one or more fuel cell modules; and
one or more super capacitors that provide interim power to the facility during any changeover time period from deactivation of a power source until subsequent activation of another power source occurs in order to provide uninterrupted power to the facility.
10. The valve and switching system of claim 9 , further comprising a sensing and control mechanism connected to the primary fuel valve, the secondary fuel valve, the switch, and the valve.
11. The valve and switching system of claim 9 , wherein the one or more super capacitors are primarily powered by the one or more rectifiers.
12. The valve and switching system of claim 11 , wherein the one or more fuel cell modules provide a backup source of power to the one or more super capacitors and to the facility.
13. The valve and switching system of claim 9 , wherein the primary fuel source comprises natural gas and the secondary fuel source comprises propane.
14. The valve and switching system of claim 9 , wherein the one or more fuel cell modules comprise one or more proton exchange membrane fuel cell modules and the gaseous fuel source comprises hydrogen.
