Though the three electricity distribution companies in the capital claim Delhi's customers owed them R19,558 crore till FY13, the regulator has put the figure at R11,432 crore till FY12 ó the gap for Fy13 is yet to be ascertained. Of this R11,432 crore, a sum of R8,000 crore is to be paid back to the companies over a period of 8 years along with an interest of 13.52% for BYPL, 13.37% for BRPL and 12.2% for TPDDL. On an average, that works out to be an extra 11% surcharge in place of the current 8%. Thatís an extra 23-25 paise per unit of electricity consumed right now. The DERC putting out a schedule for discharging the regulatory assets, if only a small part of them, immediately raises the ability of the discoms to borrow from banks.
