Transcript state sector – intrastate abt

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

•
•
•
The main steps involved to implement intraState 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 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 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
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.
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
Status on intra-State ABT
• Many SEBs restructured, others in process
• State Utilities looking for benefits of intraState 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.
