AT& C Losses??? Aggregate Technical and Commercial Losses (AT & C Losses) is nothing but the sum total of technical loss, commercial losses and shortage due to nonrealisation of total billed amount: {(Total Energy Input LESS Energy Realised)/ Total Energy Input}*100 Where, Energy Realised is Sale of Energy * Collection Efficiency Distribution Losses (Technical + Commercial Losses) is nothing but the difference between energy supplied at the Input Points and Energy Billed to Consumers in percentage terms for a particular period: (Energy Input less Energy Billed to Consumers in kWh/ Energy Input in kWh)*100 Collection Efficiency is nothing but the ratio of revenue actually realized from consumers and energy amount billed to Consumers for a particular period, in percentage terms: (Revenue Realized Consumers)*100 from Consumers/Energy Amount Billed to
