  1. INTRA STATE ABT Necessity Issues Implementation

  2. Some of the features of New National Electricity Policy – Feb.’05 • Appropriate Commissions to undertake development of power market • SERCs to notify GRID CODE by September 2005, if not yet notified • State Commissions to ensure upgradation of SLDCs by June 2006 • SERCs are advised to introduce ABT regime at the State level within one year i.e. by February 2006.

  3. Need for intra-State ABT • Accountability of utilities after reforms • Passing on UI payment • Intra State ABT to identify agencies responsible for overdrawal/underdrawal, overgeneration/ undergeneration, resulting in UI payment to regional pool. • Proper Demand forecast and load management by DISCOMs • To establish a framework for bilateral trading at intra-State level • To achieve overall merit order operation.

  4. Inter-State ABT Non-conventional source of energy e.g., wind energy Intra-State ABT IPPs CPPs • Distribution Control Centre –One for each Discom • ISGS: Inter State Generating Stations • SGS: State Generating Stations • CTU: Central Transmission Utility • STU: State Transmission Utility

  5. Intra state ABT • Pre – requisites • Unbundling of Vertically Integrated State Utilities • Allocations from ISGS/ other state owned generators to various Discoms by State Govt • Control centres in each Discom • RTUs at required locations • Generating stations • Drawal points from STU to DISCOMS on various tie-lines, ICTs • various other critical lines • SCADA information to Discom Control Centres • SEMs at required locations • Processing of SEMs data/Settlement system

  6. Intra-state ABT .what it achieves ? Harness surplus generating capacity available in state with CPPs / IPPs • Operation of grid on economic principles –Merit Order Despatch • Open Access in Intra-state Transmission and Distribution. • Generate signals for efficient grid operation at the intra-state level.

  7. Intra-state ABT –what it achieves ? • Overdrawals at low frequency by Discoms duly priced. • Encourage serving of higher consumer demand • Encourage maximisation of generation during deficit conditions. • Each Discom and state generating station responsible for its actions – a profit centre • Commercial signals available to large consumers capable of regulating drawal

  8. …Intra-state ABT – what it achieves ? • UI mechanism at the intra-state level • UI to be applied on the deviations from the schedules of the DISCOMS/State generators/IPPs/CPPs. • State Utilities to be collectively liable for the States’ liabilities with the regional UI pool account. • Achieves merit order operation for all the entities under ABT • Commercial viability of running Pumped Storage Stations.

  9. Issues needs to be addressed for intra-State ABT • Restructured SEBs • Identification of entities for intra-State ABT • Scheduling Principles & Procedures • Commercial Principle • Metering Philosophy • Treatment of existing Agreements • Organisational Development • Regulatory Issues

  10. Implementation of intra-State ABT The main steps involved to implement intra-State ABT are: • Listing of entities on which ABT/UI mechanism to be applied • Listing of Metering locations and assess the requirement of meters and accessories • Finalize the specifications for meters and accessories • Presentation of the mechanism to all concerned • Finalisation of the tariff for all generating stations in ABT format.

  11. Implementation of intra-State ABT • Finalisation of shares of each distribution zones and other commercial arrangements • Organize installation & commissioning of meters and accessories. • Organising meter reading, data transfer and computation at SLDC • Establishment of the scheduling process along with scheduling software • Presentation/training to all concerned

  12. Implementation Plan • 1st Phase Activities • Finalisation of listing of entities • Listing of Metering locations • Finalisation of technical specifications & quantities of SEMs, DCDs/MTEs • Initiate tendering process for procurement of meters & RTUs

  13. Implementation Plan • 2nd Phase Activities • Finsalisation of Tariff of State Generating Stations as per ABT parameters/norms • Finalisation of Reactive Charge scheme • Finalisation of commercial mechanism for CPPs, Wind farms, Wheeling and banking, Open Access Customers etc. • Determination of Allocations of different Discoms in State Genco/ ISGS/ IPPs.

  14. Implementation Plan • 3rd Phase Activities • Supply and commissioning of meters at different locations • Installation of software for data processing • Installation of software for scheduling / energy accounting • Training • Estimate time for implementation – 12 to 18 months

  15. Status on intra-State ABT • Many SEBs restructured, others in process • State Utilities looking for benefits of intra-State ABT • took lead for intra-State ABT • Punjab took lead in Northern Region • Road-map for Maharashtra is ready • POWERGRID assisting these States by providing consultancy • Other States like MPSEB & Haryana to follow.
