Claim 15:
16. A non-transitory computer readable storage medium containing executable instructions that, when executed by a processor, cause the processor to perform operations, comprising:
instructing a power supply unit to provide a utility power based direct current (DC) electrical power to one or more low-priority electronic components of a datacenter and one or more high-priority electronic components of the datacenter, the power supply unit receiving an alternating current (AC) electrical power produced from a utility AC electrical power provided by an electric utility source;
receiving a first indication that a demand for an aggregate electrical power provided by the electric utility source has exceeded a first threshold, wherein the aggregate electrical power includes electrical power provided by the electrical utility source to external users other than the datacenter;
instructing one or more first backup battery units electrically connected with the one or more low-priority electronic components to provide a first supplemental DC electrical power to the one or more low-priority electronic components in response to receiving the first indication, wherein the first supplemental DC electrical power offsets at least a portion of the utility power based DC electrical power provided by the power supply unit to the one or more low-priority electronic components; and
preventing one or more second backup battery units electrically connected with the one or more high-priority electronic components from discharging to prevent supplying a second supplemental DC electrical power to the one or more high-priority electronic components.
