Intermittently redistributing energy from multiple power grids in a data center context

A computer program product comprising;

• a machine readable storage device;
• and
• computer code stored on the machine readable storage device, with the computer code including instructions and data for causing a processor(s) set to perform operations including the following:
• receiving a plurality of cost information data sets, with each cost information data set respectively corresponding to a power grid of a plurality of power grids and including expected cost information for electrical power drawn from the corresponding power grid during a time period, with each power grid of the plurality of power grids respectively having:
• (i) a different origin of the electrical power distributed over the grid, and (ii) different distribution infrastructure,
• receiving a plurality of usage information data sets, with each usage information data set respectively corresponding to a data center load of a plurality of data center loads in a data center and including expected usage information for electrical power expected to be drawn by a corresponding data center load during the time period,
• determining a target power information set, based, at least in part, on the plurality of cost information data sets and the plurality of usage information data sets, with the target power information set, for the time period, including:
• (i) a first target power amount respectively corresponding to each power grid, and (ii) a second target power amount respectively corresponding to each power grid, with the second target power amount being a lowest expected usage target power amount, and
• determining a power supply unit configuration scheme according to the determined target power information set so that, when operating under the power supply unit configuration scheme, each power grid of the plurality of power grids will either:
• (i) supply, at least approximately, the first target power amount, (ii) receive power from a unique electrical energy source, and/or (iii) supply, at least approximately, the second target power amount.
