Non-Technical Loss Detection Based on Electricity Consumption Data: A Case Study in Ecuador

Abstract:

The Detect Deviating Cells (DDC) technique is applied to detect energy fraudulent customers and other irregularities based on consumption data from the public electric company supplier in Guayaquil-Ecuador. DDC successfully detected a fraction of 93% of fraudulent customers and captured the periods with irregular consumption in most cases. DDC also flagged new fraudulent customers and other irregularities that were later confirmed from new inspections made by the supplier company. DDC is therefore a cheap and effective alternative to on-site inspections for detecting energy fraud and other irregularities associated to non-Technical losses.
