Tamil Nadu's power loss pegged at 13%, Trichy tops list

Related imageTrichy region has the maximum distribution loss (19.08% - 51.11 million units) in the power sector in Tamil Nadu. Tirunelveli stands second at 15.16%, South Chennai has 13.99% loss and North Chennai 11.50%.
These are the findings of the first-ever region-wise analysis of power distribution loss in the state. Distribution loss occurs owing to old meters, old cables as well as power theft. The total distribution loss in Tamil Nadu is estimated to be 12.91%. With the changing of old meters with digital ones, the loss is likely to reduce in the coming years.
Trichy region comprises Cauvery delta region and Karur district.
"Farmers' connections in delta districts don't have meters and most of them use higher horse power pumps. For example, if a farmer has been permitted to use a 5 horse power pump, he would be using a 10 horse power pump. The extra power used is accounted for as distribution loss," a senior Tangedco official told TOI.
Tangedco estimates that farm power connections could be the main reason for Trichy region topping the distribution loss chart.
In urban areas, the loss is owing to old cables and meters.

"We have a target to lower the distribution loss in urban areas to single digit percentage, but in rural areas we hope to bring it down to 4%," said the official. In urban areas, apart from digital meters, the discom will also set up modern sub-stations to reduce distribution loss.
"Though the investment to set up modern sub-stations like gas insulated switchgear (GIS) is high, such infrastructure needs less land and it will also lower distribution loss. Such sub-stations will be set up at least in urban areas where acquiring land is a problem," said the official.
Tamil Nadu Electricity Regulatory Commission (TNERC), in its tariff report, has asked Tangedco to differentiate between power theft and transmission loss.
Unless this is done, the distribution loss trajectory may not reflect the ground reality.
