Disclosed techniques include power management across point of source to point of load. Energy is obtained from points of energy generation, where data obtained at a time of energy generation includes information on energy and metadata about the energy. Connection is enabled from the points of energy generation to a large-scale energy storage subsystem. Load information is received from points of load, where the points of load are connected to an energy grid. Processors are used to calculate an energy control policy, based on information on the energy, the energy metadata, availability of the large-scale energy storage subsystem, and the load information. Routing of the energy is controlled from the points of energy generation to the points of load based on the energy control policy. The large-scale energy storage subsystem is controlled based on the energy control policy.
