1. A system comprising:
an uninterruptible power supply (UPS) configured to provide energy power to a load and to transfer energy between an energy storage device and an electrical grid; and
a controller communicatively coupled to the UPS, the controller being configured to:
regulate energy transfers between the energy storage device, the electrical grid, and the load by permitting or preventing the energy transfers based on operational parameters including energy storage thresholds and grid conditions;
manage a reserve energy capacity within the energy storage device to maintain power delivery to the load during disruptions in power from the electrical grid while supporting energy services for the electrical grid;
modify the operational parameters, including the energy storage thresholds, in response to inputs received from a user interface or an external control system; and
coordinate operational control of the uninterruptible power supply with at least one additional uninterruptible power supply to provide aggregated energy transfer functionality while maintaining independent power delivery to each respective load.
