Electricity Policy – Feb.’05Electricity 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.

Need for intra-State ABTNeed 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.

Intra state ABT 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

Intra-state ABT Intra-state ABT ..what it achieves ?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.

Intra-state ABT Intra-state ABT ––what it achieves ?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

……Intra-state ABT Intra-state ABT – what it – what it achieves ?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.

Issues needs to be addressed for Issues needs to be addressed for intra-State ABTintra-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

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.

Implementation of intra-State Implementation of intra-State ABTABT

Implementation of intra-State ABTImplementation 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

Implementation PlanImplementation 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

• 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.

Implementation PlanImplementation 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

Implementation PlanImplementation Plan

Status on intra-State ABTStatus 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.
