There is disclosed herein a method of managing electric energy consumption and/or production dynamics, comprising the steps of: sampling an electric energy flow, adapted to be measured by an electricity metering device (1) within a network (15) of an electrical company; calculating a variation ?Ei = (Ei - Ei-1) /?t: at regular intervals, where Ei and Ei-1 are two integral sum values of electric energy amounts consolidated, over a given number of cycles and ?t represents a time interval between the respective times at which said two values are obtained; adding said variation (?Ei) to analogous variations calculated at previous times, to obtain a cumulative sum of such variations; determining whether said variation and/or said cumulative sum exceed a predetermined threshold value (dDE); transmitting a message over said network (15) from said electricity metering device (1) if said variation and/or cumulative sum exceed said, predetermined threshold value (dDE). |
