However, this may not lead to any tariff hike for consumers as surplus generated by discoms over these years will be adjusted against recoverable RA, said DERC chairman PD Sudhakar. The three discoms have had a surplus of R900 crore in their annual revenue requirements (ARRs) for 2013-14.
But the 8% surcharge on tariff imposed by the regulator two years ago, to help discoms recover RA, will effectively increase to about 11% if carrying costs (interest) on RAs are included. This will add to tariffs. Of course, any deferment of the recovery of RAs would have jacked up the interest costs and consequently the budren on the consumers.
With the DERC laying out roadmap for liquidation of RA, the private discoms can now access bank loans to finance purchase of electricity from central generating stations like NTPC and NHPC who have threatened to disconnect power supplies to Delhi discoms but cannot go ahead as they have been restrained by the Supreme Court.
The DERC will review status of RA as part of the periodic exercise to determine discoms ARR. The regulator is expected to issue tariff order for 2014-15 by July end.
Delhi discoms combined RAs is seen to reach R20,000 crore as at end of March 2013, although this is yet to be vetted by the regulator. Sudhakar told FE: There will be no addition tariff burden on consumers due to liquidation of RA as surpluses that discoms generate in coming years (as they did in 2013-14) will be adjusted against recoverable RAs. He added: Discoms are now getting cost-reflected tariff as power purchase costs are being adjusted on a quarterly basis. The RAs for 2012-13, he said, would be finalised later, based on the audited balance sheet submitted by the discoms recently.
According to Sudhakar, the DERC has deliberately taken recoverable RA on the lower side as a truing-up exercise, currently underway, which may lead to reduction in the provisional estimates.
However, the final figures may vary depending on the findings of the Comptroller and Auditor General (CAG), which is auditing the three discoms accounts for the period.
The liquidation of the revenue gap of R1,998 crore for BYPL, R3,643 crore for BRPL and R2,359 crore for TPDDL is proposed in a scheduled manner through annual equal instalments to avoid tariff burden to consumers. The annual amounts allowed to be liquidated are R424 crore for BYPL, R769 crore for BRPL and R478 crore for TPDDL over a period of eight years, the DERC has said in letters sent to private discom recently.
The matter is listed for hearing in the Supreme Court on March 26. Private discoms owe over R5,000 crore in dues to central utilties, including NTPC and NHPC.
Power tariff in Delhi is higher compared with most of states as it has to rely on distant generating stations to meet its electricity requirement. Also, Delhi discoms cannot resort to long hours of loadshedding for fear of regulatory action.
