  1. An initiative of Nodal Agency Power Finance Corporation Ltd. Ministry of Power Government of India Restructured Accelerated Power Development and Reforms Programme Interaction with TPIEA-EA, Utilities & Meter Manufacturers 3rd February 2011

  2. Background • R-APDRP envisages establishment of reliable & automated systems for sustained collection of accurate baseline data, and the adoption of IT in the areas of energy accounting under Part-A and network strengthening, improvement and augmentation works for AT&C loss reduction below 15% and performance improvement under Part-B. • The MoP/PFC has appointed Third Party Independent Evaluation Agencies -Energy Accounting (TPIEA-EA) for the verification of Baseline AT&C loss figures in the sanctioned project areas. • For Base (starting) figure of AT&C loss of the project area the state power utility / distribution Company has to ring fence each identified project area at the beginning of the programme. Three billing cycle data of energy inflow and outflow and corresponding revenue collected for the project area is to be furnished to the TPIEA-EA for verifying the base (starting) figure of AT&C loss of the project area. Part B projects will be taken up after verification of initial AT&C losses by TPIEA-EA.

  3. TPIEA-EA appointed for states 775 Part-B schemes have been sanctioned in 13 States viz. Himachal Pradesh-14, Punjab-15, Rajasthan-82, UP-155, MP-81, Gujarat-63, Maharashtra-66, AP-42, Karnataka-88, Kerala-40, TN-82, West Bengal-45, Sikkim-2. TPIEA-EA have been appointed as follows- • WAPCOS-Haryana, Punjab, Kerala, Madhya Pradesh, Uttar Pradesh & NE states( Assam, Meghalaya, Manipur, Mizoram, Tripura, Arunachal Pradesh & Nagaland • ICRA- Maharashtra, Andhra Pradesh & Tamil Nadu • NPC-Gujarat & West Bengal/Sikkim • ERDA-Chhattisgarh & Goa • CPRI-Karnataka • Voyant Solutions- Rajasthan • DRS-J&K, Uttarakhand • Pranat-Bihar, Jharkhand & Himachal Pradesh LOI yet to be converted to LOA in Goa, J&K, Bihar, Jharkhand & NE states since no ring fencing reported

  4. Utilities Scope • It is the responsibility and in the interest of Utilities to get verification of Project areas Baseline AT&C loss done by TPIEA-EA for early start of Part-B projects implementation and thus for conversion of Loan component into Grant. • Utilities should form exclusive team for completion of Baseline AT&C loss verification job in Project areas

  5. Utilities Scope Pre-requisites for verification of Baseline AT&C losses: • Ring fencing of Project Areas w.r.t. electrical vis-à-vis physical boundary by • Installation of Boundary meters at all input and export points • Segregation of project area consumers • Installation of system meters at sub-stations and feeders/lines • Ensuring healthy operation of above meters and availability of calibration certificates • Availability of electrical distribution network superimposed on project area map • Compilation of three billing cycle data on approved format (including consumer profile) and as per baseline AT&C loss computation methodology.

  6. TPIEA-EA Scope • Reporting Initial AT&C losses of all project areas as per approved methodology including • Verification of Ring Fencing of project areas • Validation of 3 cycle Energy & Revenue data • Verification of Baseline AT&C losses project area wise • Verifying Annual AT&C losses of Part-B project areas starting an year after establishment of Part-A(IT) system • Verifying Annual AT&C losses of utility as per approved methodology • Reporting Quarterly AT&C loss figures in Part-B project areas

  7. Import/Export Meter M4 11 kV feeder-1 33/11 kV Sub-station 33 kV Line M1 M2 M0 11 kV feeder-2 M3 Import/ Export Meter 11 kV feeder- 3 11 kV feeder- 4 M5 Town Periphery 33/11 kV Sub-station Project Area Map Import for EHV/HV consumer M6

  8. Import/Export Meter M4 11 kV feeder-1 Transforrner M1 33 kV Line M2 M0 11 kV feeder-2 M3 33/11 kV Sub-station 11 kV feeder- 3 Import/Export Meter M5 11 kV feeder- 4 Town Periphery 33/11 kV Sub-station Project Area Ring fencing Import for EHV/HV consumer Formula for AT&C Losses Where

  9. Gapsfound during Baseline AT&C Loss Verification Ring fencing is primarily responsibility of the utilities for their normal business, however , they are not paying due attention to this. In many case following gaps have been observed: • Utilities are declaring towns as ring fenced although the input and export energy meters are not installed at some points of Project Area boundary of its electrical distribution network. • Project area electrical distribution network superimposed on its geographical map not being provided by some utilities.

  10. Gapsfound during Baseline AT&C Loss Verification • Meters calibration certificates are not available. • There is no regular monitoring of the ‘boundary meters’ to ensure their healthiness, and in case of meter getting faulty, to replace the same within time bound time. • Arrears, subsidies & deemed collections are not excluded from the revenue collection as per the methodology • Utility to consider energy sales & revenue collection of project area only.

  11. Measures for TPIEA-EA for verification of Baseline (initial) AT&C loss • TPIEA-EA to deploy adequate manpower for completion of Baseline AT&C losses verification job in time. Before start of above work TPIEA-EA to furnish schedule of verification and manpower deployment to PFC. • To overcome the problem of repeated exercise and thus to avoid delay, TPIEA-EA must visit the town/project area • after ring fencing by Utility for physical verification of Boundary meters • after utility has submitted 3 billing cycle data for validation and certification of AT&C losses. • TPIEA-EA to ensure data consistency at different locations in the report formats. • TPIEA-EA to provide rationale (with its acceptance) for gaps in billing, collection, arrears, AT&C losses among the three billing cycles in the report.

  12. Measures for TPIEA-EA for verification of Baseline (initial) AT&C loss • Aggregate of 11KV feeder meters may be taken for computation of input energy if no meter installed at 33 kV incomer in sub-station. • TPIEA-EA shall use electrical distribution network superimposed project area map provided by the utility. • TPIEA to verify 100% boundary i.e. input and export points. • For purpose of baseline AT&C loss computation feeder wise energy/revenue billing/collection may not be insisted if the same is not available with the utility. However TPIEA to have sample check against inclusion of any non project area consumers. • TPIEA-EA to have approval of Company Secretary/Board resolution for Authorized signatory for TPIEA-EA report

  13. Installation of System Energy Meters Issues related to Utilities: • Several Utilities have not yet floated NIT/placed orders for DLMS complaint system energy meters for their R-APDRP requirements. • Some utilities are adding/deleting the meter parameters and not sticking to the meter technical specification despite of PFC advice not to do so as the Indian companion standard already includes all relevant parameters. Any deviation by utilities on this account may be treated as non-compliance of R-APDRP guidelines. • Utilities are packaging requirements of meters, CT, PT units and meter boxes etc into one package and placing the purchase order, such packaging results in poor response from bidders during bidding stage, and delay in supply of items at the time of delivery against PO by meter manufacturer.

  14. Installation of System Energy Meters Issues related to Meter Manufacturers: • Delay in meters delivery by meter manufacturers. (As the RAPDRP is flagship programme of MOP, GOI and availability of DLMS compliant meters has got delayed, no further delay is expected from meter manufacturers) • Some manufacturers are taking orders beyond their production/delivery capacity • Manufacturers are giving poor response to bids in some states. Issues related to Testing (CPRI): • Delay in meters testing by CPRI. CPRI is taking more than one month in testing of a set meters. • Requirement of submission of detail technical particulars about meters from utilities needs to be reviewed and simplified. • Sufficient CTT test benches are not available at CPRI despite of their commitment given in July’10 at Bangalore. This is causing delay in testing of meters. • DLMS compliant technical specification for meters CMRI not yet finalized.
