A method of optimizing electricity use from an electric grid is disclosed. The method includes formulating a target load using a cost function for the electric grid, broadcasting a cost signal to the electric device based on the target load, receiving a charging profile from the electric device based on the cost signal, aggregating a demand profile for the electricity use based on the charging profile, determining an updated cost signal based on the demand profile, and broadcasting the updated cost signal to another electric device. The electric device is chargeable electric device, such as a plug-in electric vehicle (PEV). The electric device determines the charging profile only once based on the cost signal, and is charged at maximum power.
