Introduction

The State Load Dispatch Centre (SLDC) is a state of the art computerised

Control Centre established under Sec 31 of the Indian Electricity Act, 2003.

The SLDC in Punjab is located at 220 KV Grid Sub-station Complex at

Ablowal, Patiala. Consequent upon unbundling of erstwhile Punjab State

Electricity Board (PSEB) on 16th April, 2010 and formation of two successor

companies namely Punjab State Power Corporation Ltd. (PSPCL) and Punjab

state Transmission Corporation Ltd. (PSTCL), SLDC was placed under PSTCL.

The SLDC headed by Chief Engineer/SLDC is the apex body to ensure

integrated operation of Power System in the State of Punjab is responsible

for performing the following functions as specified under Sec 32 of the

Indian Electricity Act, 2003 ;-

• To ensure integrated Grid operations

• To monitor & control the system parameters to maintain healthiness

of system in the state

• Optimum Load dispatch & scheduling

• To keep accounts of energy transmitted through state Grid and to

prepare intrastate energy accounts

SLDC is mainly carrying out two types of operational activities; one is grid

system operation to ensure safe, reliable and economic despatch of

electricity in the State of Punjab and the other is commercial operation for

providing Short Term Open Access (STOA), accounting quantum of

scheduled energy, unscheduled interchange (UI) energy exchange and

reactive energy exchange. SLDC organisation also operate and maintains

state of art SCADA/EMS system established since August 2002 under

Unified Load Dispatch & Communication (ULDC) Scheme which provides

real time data at SLDC & NRLDC for monitoring and ensuring integrated

operation of the power system of Punjab in co-ordination with NRLDC,

BBMB & other constituents. SLDC has also undertaken various IT activities

such as web enabled GIS mapping of complete transmission network in

PSTCL ,implementation of Boundary Metering Scheme for intrastate energy

accounting , maintaining an independent SLDC web site with advanced

features like real time data like frequency, generation, power drawl and UI.

C) Commercial Operation Achievements

Open Access is the major Commercial Activity being handled by SLDC.

SLDC being the nodal agency for Short Term open Access (STOA) in the

State, is responsible to operationalise the STOA and carry out energy

accounting, maintain and manage UI Account and Reactive Energy Account

and handle the Open Access revenue in line with open Access Regulations.

SLDC has further streamlined and strengthened the Open Access process by

developing procedures and formats for application, introducing IT in various

activities such as UI data processing and web based application handling

cum information system, to make the process transparent and consumer

friendly.

The salient commercial functions/achievements in respect of open access

are;

• Collection of Open Access Charges as levied by Hon’ble State

Commission (PSERC) for Open Access Customers in its Tariff Order and

Open Access Regulations 2011. The transmission & wheeling charges as

realized by SLDC through Energy exchange (IEX/PXIL)or RLDCs are

being remitted regularly to PSTCL & PSPCL respectively within

prescribed time frame.

• The applications for grant of Open Access are received, processed and

open access is granted within regulatory framework and policy/

guidelines of PSTCL/ PSPCL, within the prescribed time limits for each

activity.

• The UI energy accounts are also being prepared and forwarded to the

office of CE/ PP&R for finalization and onward submission to concerned

CBC of PSPCL.

• SLDC holds regular meetings of Commercial & metering Committee

formulated in line with State Grid Code to decide and sort out metering

and billing related issues arising from time to time.

• SLDC also responds to various Petitions filed with PSERC /CERC and

represent cases before the Commission both at state & central level.

• Open Access applications are being handled through e-mail and

application fee through NEFT/RTGS, based on which the monthly

Standing Clearance/ NOC for purchase/ sale of power under Open

Access is issued via. e-mail on the same day.

• As a major step towards automation, Software for online filing of NOC

taken up by Energy Exchange (IEX) in consultation with Punjab SLDC,




13

which shall be used for receiving Standing Clearance/ NOC applications

and issuing of NOC online .

• The UI energy accounts being prepared by introducing the Automatic

Billing Software Module developed in association with Energy exchanges

(IEX/PXIL) resulted in to quick processing of UI energy account within

the stipulated time frame and eliminating chances of human error The

energy accounts prepared by SLDC are also uploaded on the website for

ensuring transparency in billing.

Commercial (Open Access ) Performance Indices: 109 no. Open Access Customers have been registered for purchase of

370 MW of power under Short Term Open Access during the year 2011-

12, increasing the total no. of Open Access Customers during the year

from 227 no. to 336 no. thereby registering an increase of OA consumer

base by about 48 %. The growth of Open Access in Punjab and other

highlights are summarized as under:-

D) Infrastructural Achievements at SLDC

1. SCADA/EMS System at SLDC

• A computerized SCADA/EMS system at SLDC provides on line

data of power system on real time basis. The project was

commissioned in 2002 by Power Grid under Unified Load

dispatch & Communication (ULDC) Scheme in whole of NR

grid constituents.

• Under the scheme, all the Generating Station of PSPCL,

Interstate tie lines, important 220kV & 132 kV grid substations

of PSTCL have been covered for remote data acquisition and

control. Presently 49 nos. RTUs have been installed at the

above said locations for acquisition of online power system

data through PLCC/Microwave communication media.

• Up gradation of existing EMS/SCADA system under ULDC

Phase-II and establishment of Backup Control Centre is under

implementation by PGCIL on unified basis. (Likely to be

commissioned in 2014-15)

F) Capex Plan for SLDC

(Requirement for SLDC business for the year 2012-13 & 2013-14) 1.0 ULDC Scheme:

1.1 The initial expenditure made by PGCIL for implementation of

ULDC scheme is being recovered by it, from SLDC/ PSTCL as ULDC

Charges (for erstwhile PSEB portion, Central sector portion

proportional to Punjab’s allocation in ISGS plants & BBMB portion

proportional to Punjab’s share in its generation) through monthly

installments, as per CERC orders, amounting to Rs. 9.5 cr for year

2012-13 & Rs. 10 cr. for the year 2013-14. This recovery is to

continue tentatively till 2017.

1.2 The existing SCADA/ EMS control centres are being upgraded by

PGCIL under unified scheme called ULDC Phase-II, which also

envisages a backup control centre for disaster recovery purpose

alongwith better/ upgraded user interface tools/ reports, PMU

(Phase Measurement Units) integration, etc. The project has been

awarded by PGCIL to M/s Siemens and likely to be commissioned

during 2013-14. The expenditure amounting to Rs. 5 Cr shall be

required to be made to PGCIL during 2013-14.

1.3 RTUs addition/ replacement:

A) To further augment the ULDC scheme, 47 No. more RTUs are

already ordered for covering 41 Nos. left out/ upgraded/ new

220kV level substations in PTSCL and 6 Nos. RTUs for

cannibalizing the existing RTUs (of different makes) for spares.

Out of 47 Nos RTUs, 25 Nos RTU are likely to be commissioned by

G) Way Forward for 2012-2013

A number of opportunities and challenges exist for Punjab

Grid. Key amongst the challenges are the increasing levels of

complexity in the operation of the power system coupled with

increased quantum of renewable energy sources, portfolio of high

capacity generator units, wide variation in demand, planning of

outages for generating units and transmission elements, real time

incorporation of voluminous revisions from generators and DISCOM,

data acquisition on faster rate, assessment of transfer capabilities,

flexibility to implement frequent changes in Regulations,

implementation of intrastate Boundary Metering system to calculate

transmission losses and sub-station level energy audit & work out

transmission availability, issuance of energy accounts and statements

to all users timely and accurately etc. SLDC is required to be

strengthen by way of skilled man power and set a road map to meet

these challenges.
