Green data center and virtual power plant

A power system for cooling backup computer storage facilities having eight independent levels of redundancy for the power supply to allow the storage facility to survive even extreme and debilitating events and having redundant communications. If power from the existing gas or electric grid is lost, a series of back-up energy sources provide energy to run the micro-turbines and generate the power to run the servers and the HVAC system that cools the servers. In the event that the existing power grid is interrupted, the redundant power supplies are automatically engaged without disruption of the load. If the existing gas and / or electric power grids are disrupted, the storage facility is powered / cooled by a micro-grid having its own independent redundant sources of power.
