Abstract

The invention concerns a method of managing energy consumed by a group of energy consuming devices (31 to 39) and energy consuming devices (31 to 36) for executing this method. Energy consuming devices (31 to 36) of the group of energy consuming devices exchange messages according to an energy management control protocol via a communication media (4). The energy management control protocol comprises an energy booking message type for announcing future energy consumption, an energy reduction indication message type for announcing possible reduction of energy consumption and a granting message type for granting an energy booking message and/or an energy reduction indication. The energy consuming devices (31 to 36) negotiate their energy consumption by means of the messages exchanged according to the energy management control protocol and control their energy consumption according to the result of this negotiation.
