ANOMALIES IN T&D LOSS COMPUTATION
• In absence of feeder metering in the past, substantial portion of T&D loss, including theft of electricity gets attributed to agricultural consumption. While, agricultural consumption is around 20-25%, utilities were showing it as 35-40% and correspondingly T&D losses shown as 20-25%.
• Also, T&D loss was being computed taking into account electricity bills issued to consumers as accrued income & not on actual collection. Therefore, T&D loss figures did not capture the major gap between the billing and the collection, apart from large amount of theft.
• To get over this problem, concept of Aggregate Technical & Commercial (AT&C) loss was introduced.
4
AT&C LOSS It is the difference between units input into the system and the units
for which the payment is collected. T&D Loss do not capture losses on account of non-realisation of
payments. AT&C Loss is the clearest measure of overall efficiency of the
distribution business as it measures technical as well as commercial losses.
AT&C Loss(%) = (Energy Input – Energy Realised)X100
Energy Input Energy Realised = Energy Billed X Collection Efficiency
Collection Efficiency (%) = Amount Realised X100
Amount Billed
