Claim:
1. A method comprising: estimating, by a supervisory control and data acquisition (SCADA) system located at a rood node, an estimated electrical energy consumption value for a predetermined time interval; measuring, by the SCADA system, an actual electrical energy consumption value corresponding to electrical energy supplied by the root node of a grid during the predetermined time interval; determining, by a computing device, that a mismatch between the estimated electrical energy consumption value and the actual electrical energy consumption value exceeds a technical loss threshold such that non-technical losses were experienced by the grid during the predetermined time interval; receiving, from a plurality of smart meters respectively located at a plurality of energy consumption nodes, over a communication network and by the computing device, a plurality of voltage values collected during the predetermined time interval, with the plurality of voltage values indicating voltage levels experienced at the respectively corresponding smart meters; and responsive to the determination that non-technical losses were experienced by the grid, determining, by the computing device, a location the non-technical losses based on the voltage values collected from the plurality of smart meters.
