A design for the electrical infrastructure of a data center enables two different configurations to be utilized, including a distributed, redundant configuration that provides higher reliability and a non-redundant configuration that provides higher capacity. In the distributed, redundant configuration, each server in the data center draws power from at least two different power supply systems. This enables load shifting when a power supply system becomes unavailable, which can have the effect of increasing server reliability. In the non-redundant configuration, each server in the data center draws power from only one power supply system. Load shifting is not utilized in the non-redundant configuration, which eliminates the need to maintain reserve capacity and thereby increases capacity. Advantageously, it is possible to switch between these two configurations without making any internal changes to the data center other than modifying connections between sets of server racks and power buses.

Variable reliability and capacity data center design

Key interlock systems and methods are described for safely carrying out a closed-transition procedure in an electric power distribution system in which two load busses that can be separately powered by the same power source or by two different power sources can be connected together via one or more bus tie breakers and in which a static transfer switch is used to selectively deliver power from one of the two different power sources to at least one of the load busses. Embodiments described herein prohibit access to a key that is required to close a bus tie breaker that connects the two load busses until at least a determination is made that a particular bypass breaker of the static transfer switch has been closed, thereby ensuring that both load busses are connected to the same power source.
