Systems and methods are described for a power aggregation system. In one implementation, a method includes establishing a communication connection with each of multiple electric resources connected to a power grid, receiving an energy generation signal from a power grid operator, and controlling a number of the electric resources being charged by the power grid as a function of the energy generation signal.
