Techniques for providing auxiliary power to a datacenter, which is normally serviced by a power utility, are disclosed. The system includes a controller, a first stamp, and a second stamp. A common DC bus couples the first stamp to the second stamp on a DC side. A common AC bus couples the first stamp to the second stamp on an AC side (e.g., the output of the stamps). An AC breaker is disposed on the AC bus between the first stamp and the second stamp. The controller controls whether the AC breaker is open or closed. A default state of the AC breaker is an open state. The control of the breakers can occur for various reasons, including whether the utility is available or whether the utility is not available. The utility might not be available due to a utility failure or due to other reasons.
