Method implemented by a device, called a centralising meter, included in an automated metering management system in the context of an electrical distribution service, the centralising meter comprising a first powerline communication unit configured for communicating with a data concentrator via a first powerline communication network in a first frequency band, the centralising meter further comprising a second powerline communication unit configured for communicating with a plurality of devices, called remote basic meters (131, 132, 133), via a second powerline communication network in a second frequency band distinct from the first frequency band, the method comprising the following steps: - emulating a smart electricity meter application (131, 132, 133) with respect to the data concentrator for each remote basic meter (131, 132, 133) registered with the centralising meter via the second powerline communication network, each emulated application (311, 312, 313) constructing a load curve for the corresponding remote basic meter (131, 132, 133); - measuring, by a general metrology unit of the centralising meter, the electrical consumption of all the electrical installations that the remote basic meters (131, 132, 133) are responsible for supervising; - when the ΔEa D /ΔEa G ratio of an energy consumption ΔEa D declared by all the remote basic meters (131, 132, 133) during a time T to an energy consumption ΔEa G measured by the general metrology unit during the time T is below a predefined threshold and furthermore the load curves of a plurality of remote basic meters (131, 132, 133) show a drop to zero of the energy consumption, identifying which remote basic meter (131, 132, 133) is subject to an energy-consumption fraud, by extrapolating the load curves of said plurality of remote basic meters (131, 132, 133) and comparing the total energy consumptions ΔEa E estimated from the extrapolated load curves with said energy consumption ΔEa G. - emulating a smart electricity meter application (131, 132, 133) with respect to the data concentrator for each remote basic meter (131, 132, 133) registered with the centralising meter via the second powerline communication network, each emulated application (311, 312, 313) constructing a load curve for the corresponding remote basic meter (131, 132, 133); - measuring, by a general metrology unit of the centralising meter, the electrical consumption of all the electrical installations that the remote basic meters (131, 132, 133) are responsible for supervising; - when the ΔEa D /ΔEa G ratio of an energy consumption ΔEa D declared by all the remote basic meters (131, 132, 133) during a time T to an energy consumption ΔEa G measured by the general metrology unit during the time T is below a predefined threshold and furthermore the load curves of a plurality of remote basic meters (131, 132, 133) show a drop to zero of the energy consumption, identifying which remote basic meter (131, 132, 133) is subject to an energy-consumption fraud, by extrapolating the load curves of said plurality of remote basic meters (131, 132, 133) and comparing the total energy consumptions ΔEa E estimated from the extrapolated load curves with said energy consumption ΔEa G.
