BANGALORE: Power distribution loss in Bangalore has come down to 9.5 per cent and less than 15 per cent in 52 towns with a population of 20,000, thanks to a Distribution Transformer System (DTC)-wise energy audit introduced last year by Bangalore Electricity Supply Company Ltd. (BESCOM).

The distribution loss in 52 towns was in the range of 19 to 21 per cent before the audit was undertaken. "The average energy loss in Bangalore is now around 11 per cent," BESCOM Managing Director G. Kumar Naik told presspersons here on Saturday.

Since cities and towns consume 60 per cent energy and fetch 80 per cent revenue, the DTC-wise energy audit was first implemented in urban areas. "Energy meters of all consumer installations fed by each of the DTC were read on the same day along with the corresponding DTC meters. The energy audit was conducted by comparing DTC consumption with the total consumption of all connected installations. The reading and consumption of each individual installation under each DTC were studied and analysed," Mr. Naik said.

Transformers were graded according to the percentage of loss. Those with higher loss percentage were identified. "All installations fed by such transformers were rated, meters calibrated and erroneous meters replaced. Cases were booked against offenders," he said.

Of the 16,948 transformers in 52 towns, 16,738 were provided with meters and energy auditing done for 16,017 transformers, he said.

He said 13 lakh installations were rated, 1.16 lakh erroneous meters replaced and 2,327 cases booked for cognisable offences. A sum of Rs. 3.56 crores was claimed through cognisable and non-cognisable cases during the period of operation.

He said the DTC-wise audit will be extended to rural areas this year. "There are 70,000 transformers in the rural sector. As a first step, 768 villages with a population of 2,000 have been identified, covering about 3,000 DTCs, for which energy audit is underway," he added.

Sixty per cent of these transformers showed loss figures of more than 10 per cent. The loss will be reduced by extensive rating of installations and vigilance exercises in the next few months.
