Vizag is all set to go in for underground power cabling at a cost of Rs 720 crore to the exchequer. Rs 400 crore will be borne by the World Bank.

The advocates of underground cabling argue that the city needs it in the wake of calamities such as Hudhud.

It also helps to reduce pilferage and thereby results in lesser transmission losses. However, it is yet to be proved that underground cabling will result in decrease in transmission losses.

Also, if something goes wrong with normal cabling, it can be rectified pretty soon. Underground cabling repairs can take a lot of time.
