  3. Energy availability

  4. Proposed Revenue Requirement in 2011-12 Power purchase cost largest component; in FY 10-11 (approved) it was 86% of revenue requirement

  5. Analysis of ARR and BSP

  6. Energy Avialability

  7. Power Purchase cost details • Purchased pattern: Hydro = 29%, Thermal = 70%, RE = 1% • Overall energy availability 23689 MU @ 214.54 Paise / Unit

  8. TTPS and CGS Observation: • TTPS: • Fixed charges for TTPS claimed 368.31 Rs crore by GRIDCO (based on NTPC’s petition) • U.I Over drawl = claimed Rs 6.38 crore during FY 2011-12 • CGS: Transmission loss of 3.09% and transmission charges of 20.17 Paise / unit Submission: • Fixed charges for TTPS shall be allowed as per earlier OERC order i.e. 200.88 Rs crore. Fixed charges as requested by GRIDCO shall not be allowed in ARR since the final order is not issued by CERC • The U.I. over drawl for FY 11-12 cannot be judged at this time and therefore can not be considered • Transmission loss and transmission charges claimed for CGS may be reviewed based on actual data

  9. Central Thermal – Fixed charges and FPA • Income tax may not be approved as a part of fixed cost • Projected FPA may be reviewed based on % rise in actual average six monthly data

  10. CGP, IPP and RE Observation: • GRIDCO has proposed to buy power from • CGPs and Co-generation plants as per OERC order@ 299.39 and 275 P/U respectively • SHP @ average 315 P/U (300 MU) • IPP @ 275 P/U Submission: • As per interim orders on SHPs the tariff for SHP shall be considered as average @ 305 P/U • In case of IPP, Commission may examine the PPA and approve the rate

  11. Power purchase rate comparison Proposed tariff for TTPS needs to be examined for substantial rise

  12. Special Appropriation • Submission: • Loan related supporting documents and utilization of loans not matching with bove figures. • Commission may scrutinize the details with reconciling the earlier provisionally approved amounts. • Arrear payment to NTPC as per tariff petition; Commission may not approve now

  15. Energy sale projection by GRIDCO Wide variation in GRIDCO’s sale and DISCOM’s purchase projection

  16. Power purchase cost by GRIDCO vs. BSP

  17. Impact of BST on average cost of supply Assumption: (i) T&D loss of HT - 8% and LT- 29.4% (ii) EHT and HT Consumption as proposed by Discoms in respective ARR

  18. Summary • Design of BSP for DISCOMs has direct impact on consumer tariff; therefore, the Hon. Commission may consider the following observation of Consumer Counsel related GRIDCO ARR: • Energy availability from all sources may be reviewed • Review of fixed charges and UI over drawl in case of TTPS • Review of fixed charges and FPA in case of Central thermal • Review of transmission loss and transmission charges in case of Central sector projects • Power procurement rates from CGP, Co-gen, IPP and RE may be reviewed • Interest on proposed new loan shall not be pass through in the ARR • R&M cost and RoE shall not be pass through in the ARR • Energy sale to DISCOMs may be reviewed based on DISCOMs submission
