Power consumption management method

An energy consuming device of a group of energy consuming devices, the energy consuming device having

• a communication unit for communicating with other energy consuming devices of the group of energy consuming devices and/or with an energy management control device and/or with an energy management measuring device,
• a protocol handling unit for handling an energy management control protocol, the energy management control protocol comprising an energy reduction indication message type for announcing possible reductions of energy consumption, said messages of energy reduction indication message type including a priority indicator specifying how much the respective power consuming device is hindered by the indicated reduction of energy consumption, said protocol further including an energy booking message type for announcing future energy consumptions, and a granting message type for granting an energy booking message and/or an energy reduction indication message, and
• a control unit for negotiating the energy consumption of the energy consuming device by means of the protocol handling unit and controlling the energy consumption of the energy consuming device according to the results of this negotiation.
