A computer-implemented method for managing power usage of a computing device based on power-management information from a power grid may comprise: 1) receiving power-management information from a power grid, 2) identifying power-usage requirements of the computing device, and then 3) determining, by analyzing the power-management information and the power-usage requirements of the computing device, whether to adjust power usage of the computing device. The method may also comprise adjusting the power usage of the computing device in accordance with the power-management information. Corresponding systems and computer-readable media are also disclosed.
