Power GenerationPower GenerationIndia has fifth largest power

generation capacity in the world.Installed capacity of 162 GW (about

4% of global power generation).Per capita consumption 704 kWh

(world average at 2300 kWh)11th plan target of 1000 kWh per

capita consumption requires additional 100 GW power generation by 2012.

Power TransmissionPower TransmissionThe current installed transmission

facility is only 13% of total installed capacity.

Ministry of power plans to establish integrated National Power Grid by 2012 with 200,000 MW power generation and 37,700 MW (additional 20,750 MW planned during 11th plan) inter-regional power transfer capacity.

Power DistributionPower DistributionTransmission & Distribution losses

stand at 33% substantially higher than global benchmarks.

Reforms have been undertaken through unbundling State Electricity Boards into separate power generation, transmission & distribution units.

Privatization of power distribution initiated through outright privatization or franchisee route.

Power Distribution Power Distribution continuedcontinuedWhile there has been slow and

gradual improvement in metering, billing & collection efficiency, the current losses still pose a significant challenge for power distribution companies.

TRANSMISSION NETWORK

Transmission HistoryTransmission HistoryAnalog meters need logging of data by

persons.Controlling of over drawl by utilities is not

possible.Lot of time is required to collect and

summerise data for transmission lines running in 100’s of KM.

No Grid discipline.Localised operation was possible. Quality parameters( Voltage, frequency

andPF) monitoring was missing Non availability of monitoring system was

one of the reason for not connecting different regional grids.

SCADA SUPERVISORY CONTROL ANDDATA ACQUISITION

Was introduced in 2002

As the name SCADA (Supervisory Control and Data Acquisition) implies its functions are two fold:

Scans the monitored system, obtaining and deriving data about the state and operating behavior of devices

&Provides the capability to send

control signal out to those devices to modify their operation

AVAILABILITY BASED TARIFF

Intra-state ABT is a techno-economic tool for bringing rational tariff structure for supply of electricity from State generators to the distribution Licensees.

It is a mechanism for enforcing discipline in the Grid.

Benefits of Intra – State ABTa) Benefits to the Power System

Brings about grid discipline by maintaining frequency in prescribed band (49.5 to 50.5 Hz).

Ensures optimum utilization of available generation capacities.

Enhances opportunities for Open access, and Trading of electricity.

Scope for encouraging competition among generators.

SCHEDULINGFollowing processes of Scheduling has been automatized:

Declared Capacity (Input) Entitlement Generation Discom’s requirement (Input) Open Access Transactions Inter Discom Transfer (Output) Drawl Schedule Generation Injections Schedule Generation Unrequisitioned surplus Generation Schedule generation on the basis of generation back-down. Printouts of the schedules on the intranet portal of SLDC. Automatic uploading of schedules on SLDC website on the

lines of WRLDC. Automatic calculation of Inter-discom Transfer of surplus

power.
