Claim 2:
3. A computer-implemented method, comprising:
providing a utility power based direct current (DC) electrical power to low-priority electronic components and high-priority electronic components of a datacenter by a 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 electric utility source to external users other than the datacenter; and
in response to receiving the first indication, causing one or more first backup battery units configured to supply backup electrical power to the low-priority electronic components to supply a supplemental DC electrical power to the low-priority electronic components while preventing discharging of one or more second backup battery units configured to supply backup electrical power to the high-priority electronic components, wherein the supplemental DC electrical power is supplied to the low-priority electronic components in conjunction with the utility power based DC electrical power provided by the power supply unit.
