  "textContent": "A power management system includes power monitor circuits and a power manager circuit. The power monitor circuits each measure actual power supplied to one of the user electronic devices (UEDs). The power manager circuit negotiates with the UEDs agreement for subscription power levels that the UEDs are authorized to be supplied. The power manager circuit allows an oversubscription state by operations agreeing to subscription power levels for the UEDs that when combined exceeds a maximum power supply capability of the power management system. The power manager circuit, for each UED, determines a present actual power usage of the UED based on the measurements, determines a present total actual power usage of the UEDs, and responds to the present total actual power usage exceeding the maximum power supply capability minus a first threshold offset, by renegotiating an agreement with at least one of the UEDs for a lower subscription power level.",
