1 Introduction

Pursuant to the applicable provisions of the Electricity Act, 2003 the State Government shall

establish a State Load Dispatch Center (SLDC). Section 31 (2) of the Act, provides that the said

SLDC shall be operated by a Government Company / Authority / Corporation constituted by or

under any State Act and that until such Company / Authority / Corporation is notified by the State

Government, the State Transmission Utility (STU) shall operate the SLDC. The Government of

AP notified in G.O.Ms.No. 8, dated 17-01-2004 that the existing SLDC shall continue as SLDC

and be operated by the APTransco being the STU, until the State Government establishes a

Government Company / Authority / Corporation. As a result APTransco is presently carrying out

solely, the Transmission & SLDC business as the State Transmission Utility (STU) in the state.

The purpose of this filing is to propose for levy and collection of annual fee and operating

charges of SLDC business. Section 32 (3) of the Electricity Act, 2003 provides for levy and

collection of such fees and charges from the generating companies and licensees engaged in the

intra-state transmission of electricity as may be specified by the State Commission.

As per the clause 6 of Regulation (Regulation No. 1 of 2006 dated July 27, 2006), on levy and

collection of fees and charges by State Load Dispatch, APTransco has to file with the

Commission, an application / petition for the second control period with statements containing

details of the Fee and Charges under its currently – approved levels of fee and charges along

with the proposals for the Third Control Period of 5 years for FY 2014-15 to FY 18-19.

In compliance with the APERC Regulations and Guidelines, APTransco, the State Transmission

Utility & Transmission licensee managing the SLDC business (as per G.O.Ms.No. 8 dated

17.01.2004) herein submits the following in this Petition:

i. Analysis of Performance of FY 2008-09 and Second Control period from

FY2009-10 to FY2012-13.

ii. Revised Estimates for FY2013-14

iii. Annual Fee for the Third Control Period (FY 2014-15 to FY 2018-19)

iv. Operating Charges for the Third Control Period (FY 2014-15 to FY 2018-19)


10

2 True Up - Analysis of Performance from FY 2008-09 to FY 2012-13

APTRANSCO had filed for determination of ARR for SLDC for the 2nd control period (FY 2009-10

– FY 2013-14) and the Hon’ble commission had determined the ARR and charges based on

principles laid out in Regulation 1 of 2006.

The actual costs and revenue vary with the cost and revenue approved by APERC for the

2nd control period. Following is the variation w.r.t costs and revenue for the years FY 2008-09 to

FY 2012-13.

2.1 Operating Expenses True Up:

Operating Expenses consist of the following expenses:

Employee Expenses

Administration and General Expenses

Repair & Maintenance Expenses

Other Miscellaneous expenses

There is a significant variance in the actual employee expenses as compared to the expenses

approved by the Hon’ble commission. The salaries of employees of SLDC were revised in FY

2010-11. This contributed in an increase of employee expenses.

The details of the O&M expenses approved by the commission, actual O&M Expenses and

variation in expenses are as given below: in

O&M Expenses - APERC vis-à-vis Actual

Parameter Unit2008-09 2009-10 2010-11 2011-12 2012-13 Total

As could be seen from the above table, from year FY 2008-09 to FY 2012-13, Rs.41.33 Crs

excess expenditure was incurred than the approved expenditure. The employee expenditure

increased by Rs.33.07Crs, A&G expenditure increased by Rs.1.28Crs and Repairs &

Maintenance expenditure increased by Rs.5.5 Crs than the approved expenditure in the Tariff

Orders.

Almost 85% of the variance in O&M expenses is due to an increase in the Employee Expenses

during the 2nd control period. The employee expenses increased only after FY 2010-11 due to


12

revision in pay for the employees of SLDC. This was already mentioned by APTRANSCO during

the filing of MYT for 2nd Control Period for SLDC activity.

The increase in repairs and maintenance cost is due to the AMC of EMS/ SCADA system as long

term service agreement has been entered with M/s Power Grid for AMC of EMS/ SCADA system

for three years from 01-01-07 to 31-12-09 with a provision for extension of the LTSA for a further

period of 2 years at the same prices, terms and conditions. The LTSA from 01-01-07 to 31-12-09

had offshore component which varied as per dollar exchange rate and hence, the charges for the

period varied. After completion of 01-01-07 to 31-12-09 period, Karnataka opted out of the LTSA

and as the supplier insisted on fixed amount for the southern region, Karnataka amount was

shared among rest of constituents and hence AMC charges increased. The LTSA payments are

made as per the MoU entered

Hence, the R&M expenses have increased during the control period. We would humbly request

the Hon’ble commission to consider the increase in expenses.

2.2 Capital Cost True Up:

Capital Cost approved in the Tarff Order would cover the repayment of principal and payment of

interest on investment in a year, plus any residual capital cost of past investment.

But, the actual Capital Cost varies from the Capital Cost approved by the Commission mainly

due to the following reasons:

The year on year actual investments made by SLDC do not match the investments envisaged by

the commission.


13

The details of the capital cost incurred vis-à-vis the Hon’ble Commissions approved capital cost

is shown below table:

The actual residual value at the begging of FY 2008-09 was INR 16.59 Crs Vis-à-vis INR 26.37

Crs estimated by the commission. The actual investments made during 2nd Control period are

less than the approved investments in the Tariff Order.

2.3 Revenue True Up:

3 Determination of SLDC Annual Fee for 3rd Control Period

The Hon’ble Commission has notified the Regulation No.1 on “Levy and collection of Fees and

Charges by SLDC” (Regulation No. 1 of 2006) dated July 27th 2006. As per the above regulation,

the APTRANSCO has to file an application for Annual Fee and Operating Charges for the Third

Control period of 5 years from FY 2014-15 to FY 2018-19.

Filing for Annual Fee

In compliance with Clause of Regulation 1 of 2006, APTRANSCO has to determine the Capital

cost for the period FY 2014-15 to FY 2018-19 based on the methodology suggested by the

Hon’ble commission and then compute the Annual SLDC charges. The Capital Cost covers the

repayment of principal and payment of interest on the investments made in a year

Annual SLDC Fee (Rs /MW/Annum) = (Capital Cost (CC) (in Rs) / Total Generation Capacity

(MW) )

APTRANSCO has computed the Annual SLDC charges based on the following methodology:

Estimation of Year on Year Investments for the period FY 2014-15 to FY 2018-19

The new CapitalI Assets proposed to be added during the Third control period and the need for

such capital assets for SLDC business in each of the wings viz., Grid Operation,

Telecommunication, Power System and Commercial/Energy Billing Centre wings is detailed

below.

A. Grid Operation wing:

In the above investment plan, Grid Operation wing is proposed to upgrading the existing ULDC

SCADA system

The present ULDC SCADA system is over 10 years old and the hardware and software systems

are now getting obsolete. Hence, APSLDC is upgrading the existing ULDC SCADA system with

state of the art technology in consultation with Power Grid Corporation of India Limited along with

the other Southern Region constituents viz., Kerala, Pondicherry and SRLDC.

The project execution has commenced and it is scheduled to be commissioned by ending of FY

2013-14. Hence, the large capital investment proposed in FY 2013-14.

As per present security standards for critical infrastructure, redundancy of Control Centre is

essential. Hence, the Up gradation scheme seeks to implement a remotely located (in a different

seismic zone) fully functional replica Control Center, to which all the field locations report the

real-time data parallel, on a redundant communication path. The communication protocol is being

upgraded from the present serial communication link based IEC 60870-5-101 to the Ethernet


17

based IEC 60870-5-104 for enhancing the data rate. For this purpose, the APTRANSCO

communication system is also being augmented.

The new system has a provision for the acquisition of data from over 1500 field locations by

means of newer communication protocols and hardware, as compared to the 140 field stations

now being monitored. Data Concentrator Cum Protocol Converters (DCPCs) will be located at 16

identified broadband locations for collecting data from the existing and new RTU stations, which

will report to the DCPC over IEC 60870-5-101 protocol. The DCPCs will in turn report to both the

main and backup SLDC over redundant communication routes, over IEC 60870-5-104 protocol.

The planned lifetime of the new project is 7 years as per the CERC regulations.

The new system provides the operators with new tools such as Complex Event Processing

(CEP) engines for enormous data storage and it’s near instantaneous retrieval; common

information model (CIM) based modeling and data exchange, Dispatcher Training Simulator

(DTS) for training, tools for better visualization of the SCADA Displays, to aid them in better Grid

Control and Visualization.

The Control Center will have a 6x3 Unit video projection system with each unit of size 70”

diagonal. This provides the operator with an excellent visualization for the large grid network.

This is in addition to the individual two monitor workstation provided to each operator.

A new DTS is also envisaged for training the operators on the new system. It will also aid the

new operators in getting trained before being posted on the job.

In view of the requirement of having SLDC data on the Internet, a dedicated APSLDC website

with real-time and historical data is being developed. The upgraded SCADA system also will

integrate seamlessly to this website with recommended cyber security systems and email

systems in tow.

The cyber security systems will have dedicated firewalls for internal and external networks apart

from IPS and IDS apart from online automated patch management solutions, antivirus solutions,


18

file sharing mechanisms, and single point user authentication systems. A Network Management

System is also envisaged.

Historical Data of up to seven years will be available online in the new system. The backup of the

system software and data will also be automatically taken periodically at both local and remote

location on different media. The AMC of the new system will be done by the supplier for a period

of 6 Years after the mandatory 1 year warranty, post commissioning of the system. The AMC is

also part of the Project Tender itself.

In addition to that grid operation wing, also proposed to add the assets like computers, printers,

LCD Display units, up gradation of software for various PCs in the 3rd Control Period.

B. Telecom wing:

For strengthening and Modernization of Telecom equipment the following schemes are proposed

during the second control period.

a) Communication to Back up SLDC at Tirupathi :

The provision of communication system in Transmission network for Back up SLDC, at

Tirupathi is proposed in view of the Up-gradation of existing SCADA EMS system with

Main SLDC at Vidyut Soudha, Hyderabad and Back up SLDC, at Tirupathi.

The main thrust and emphasis is laid on:

i. Providing reliable real time data (of all 220KV and 400KV SS and Generators) to Grid

operators of SLDC.

ii. Providing of data connectivity to Back up SLDC which is a fully functional replica of

Main SLDC and which shall take over operation in case of any emergency.

iii. Providing high speed secured data route with redundancy for all RTU locations.


19

The backup SLDC shall be a functional replica of Main SLDC so that it can function as a

full-fledged SLDC in case of any disaster. In this scheme, the full functionality of the

backup SLDC as far as the infrastructure is concerned shall be similar to the Main SLDC.

As per new SCADA EMS Up-gradation scheme proposal, all the existing and upcoming

RTUs would report to both the control centers i.e., Main SLDC & Back up SLDC preferable

over IEC 60870-5-104 protocol. RTUs coming through 101 protocol will be converted to

104 protocol through protocol convertor. Both the control centers Main and Back up will be

integrated with Distribution companies control centers as well as SRLDC, Bangalore on

ICCP links.

To meet the high speed multi data channel requirement, Optic Fibre based broadband

communication system is proposed in certain areas and Digital PLCC based

communication is proposed in certain links where execution of OFC works is difficult and

to have redundant data paths also.

Investment approval was accorded for the above scheme vide CRN:APT/TS/ULDC-up

gradation of communication/F-INVST-26/2012 by Hon’ble APERC.

b) ULDC Project commissioned during the year 2000-2002.

Power Grid and all constituents in Southern Region have implemented the Unified Load Dispatch

and Communication project for a sophisticated, reliable and secured load dispatch operations

with ALDCs, SLDCs and RLDC at Bangalore during the year 2000-2002 for transfer of real time

data from RTU location to ALDCs, SLDC and RLDC in Southern Region.

As a part of the ULDC project, the following systems are proposed:

Fibre Optic Transmission system (FOT) consisting of Optical line terminal equipment

(OLTEs)

Digital Microwave and MUX communication system with Network Management system

(NMS).

Laying of ADSS cable


20

c) Up gradation of existing Marconi make OLTEs commissioned under ULDC:

M/s. Marconi make OLTEs were commissioned in ULDC project in Southern Region during 2000-

2002. The following difficulties were experienced during the maintenance of the equipment.

Up gradation / modification & rectification of software corruption to be carried out by OEM

only as the software is proprietary in nature.

There is no repairing facility in India, the faulty cards of these OLTEs shall be sent to M/s.

Marconi, Italy for repairs which involves customs duty assessment etc.

In view of the above, APTRANSCO has accorded approval for AMC of OLTEs with M/s.

Ericsson along with all other constituents of Southern Region up to 31-03-2009.

Due to change in technology, M/s. Ericsson had withdrawn the support of further

maintenance w.e.f. 01-04-2009 and advised for network modification or up-gradation with

new hardware and software.

In view of the above, PGCIL have conducted several meetings to arrive a solution and reached to

a conclusion along with all constituents and APTRANSCO opined to deliberate issue at SRPC.

CEA suggested for adoption of latest technology which will support to the PMU (Phasor

Measurement units) which would be a part of smart grid in near future. Hence along with other

constituents in Southern Region, APTRANSCO also agreed for up-gradation of existing SDH

fibre optic equipment (OLTE) commissioned under ULDC project for transfer of real time data

from RTU locations to 4 ALDCs, SLDC and thereon to RLDC.

Hence APTRANSCO proposed up gradation of OLTEs.

d) Up-gradation of existing MUX commissioned under ULDC:

Alcatel make MUX equipment and NMS installed in ULDC project in Southern Region were

maintained by the original OEM M/s. Alstom Transmission & Distribution system with separate

charges for repair/replacement of faulty cards with increase in the AMC charges @ 10% of

amount year by year up to 31.12.2012.


21

During the year 2013, M/s. Alstom have increased the AMC by 15% on the existing AMC charges

due to change of technology and non-availability of spares and PGCIL also imposed the

overhead charges @ 15% over and above the contract price of AMC charges and M/s. Alstom

have not covered the rectification of faulty modules. APTRANSCO did not accept for increase in

AMC and PGCIL overhead charged and withdrawn from AMC and are presently being

maintained by APTRANSCO engineers with the available spare prints.

The present MUX equipment served more than 10years and also due to vast technology change

in communication system, it is necessary to upgrade the existing system. Hence we propose this

up gradation.

e) Replacement of existing ADSS cable laid under ULDC scheme by OPGW:

As per CERC Regulation of Grid code (IEGC) clause no. 4.6.2 reliable and efficient speech and

data communication system shall be provided to facilitate necessary communication and data

exchange and supervision/control of grid.

Subsequent to the commissioning of ULDC, volume of data and no. of substations/generating

stations have increased considerably. Number of hops for data transmission is increasing with

expansion of network. In addition to the requirement of communication system for SCADA

system, Special Protection schemes (SPS) are to be implemented and installation of PMUs and

Grid Security Expert System (GSES) are also envisaged. Each PMU requires minimum 64kbps

bandwidth. SPS requires transfer of signals over no. of hops. These additional requirements of

communication for the existing and upcoming substations can’t be met unless provided with

OPGW based communication link.

The ADSS cable laid under ULDC project have served more than 10years life period and giving

frequent problems. Due to change in technology and introduction of OPGW cable (Optical fibre

with ground wire), it is proposed to lay OPGW cable in place of ADSS cable because of dual

functionality of grounding and communication and most preferred aerial cable considering fibre

security and long life for transfer of real time data from RTU locations to 4 ALDCs, SLDC and

thereon to RLDC.

C. Energy Billing Center wing:

EBC wing of SLDC, is receiving Boundary meters (Generation to Transmission and Transmission

to Discoms) MRI data, manual readings from the field and on processing the above data through

various Billing applications could able to generate Transco-Discom Energy certificate, Discom-

Discom Energy & cost settlements reports and also generating Transmission Losses data for

various purposes. EBC has also developed software for Open Access users within state as per

APERC Regulation No. 2 of 2005 & Regulation No. 2 of 2006 which is web based application. All

the Open Access users as per Regulation 2 of 2006 may have to send or receive the relevant

data through this application. Further Open Access users can also view /download various

settlement data through this application.

EBC proposes to procure new Furniture, H.P Proline server (2Nos) to replace existing old

servers ,Printers for HP Color Laser Jet and also proposed provide dedicated leased line

Internet Service to its center in the 3rd Control Period for smooth functioning of Energy Billing

Center. Presently limited open access users are existing the same is expected to increase in due

course of time, for which necessary software with applicable licenses are needed to improve the

accessibility of web application to open access users. As such the propose infrastructure shown

in the investment plan is very essential

D. Power Systems:

Proposed to upgrade the outdated software currently in use for System Software, Generation

Planning Software, Transmission Planning Software and Load Forecast software.

4.1 Employee Cost:

The employee cost for the base year FY 2013-14 has been projected based on the actual growth

rate observed in the employee expenses observed during the period FY 2008-09 to FY 2012-13.

Employee Expenses for 13-14 = (Employee Expenses for 12-13) * (CAGR (Emp exp 12-13/ Emp

exp 08-09))

The same growth rate has also been considered for projecting the employee expenses for the

3rd control period.


26

The employee cost, other than the salaries of the personnel, also contain the following

components:

Surrender leave

Various medical allowances

Other Allowances and pension contribution

Next wage revision is due with effect from 1st April 20104. The financial commitment of wage

revision will be claimed based on actuals

4.2 Administration and General Charges:

The Administration and General(A&G) cost for the base year FY 2013-14 has been projected

based on the actual growth rate observed in the A&G expenses observed during the period FY

2008-09 to FY 2012-13.

A&G Expenses for 13-14 = (A&G Expenses for 12-13) * (CAGR (A&G exp 12-13/ A&G exp 08-

09))

The same growth rate has also been considered for projecting the A&G expenses for the 3rd

control period.

4.3 Repairs and Maintenance Costs:

As per the clause No. 7 of Regulation 2/2006, the Energy Billing Center is also considered as the

SLDC Business. Therefore the assets of SLDC Business are mainly in Grid Operation unit,

Energy Billing Center and Telecom units. At present the Telecom unit assets are shared by the

Transmission business as well as SLDC business.

However for the purposes of calculation of operating charges certain amount of Repairs and

Maintenance expenses have been considered in the SLDC business.

These costs are primarily for the RTU’s and the SCADA system. The repairs & Maintenance

expenditure is projected based on the requirements of each wing.


27

A. EBC:

For smooth operations of Open Access and data collection system the following are essentially

required for AMC viz: Servers, Workstations, HUBs, Switches and procurement of consumables

like Printer cartridges and data cartridges to take the database backup and other computer

consumables for use in EBC wing is included in R&M cost.

B. Grid Operation:

The R&M expenditure projections cover for Annual Maintenance Charges for the following

equipment available in Grid Operation wing.

AMC of EMS/SCADA system till the up gradation of EMS/SCADA system gets completed,

AMC of new EMS/SCADA .

AMC of UPS systems at SLDC, ALDCs and Backup SLDC.

AMC of Air Conditioning Units at SLDC, ALDCs and Backup SLDC.

AMC of DG sets at SLDC, ALDCs.

AMC of HP Servers, PCs and printers at SLDC & ALDCs.

AMC of networking equipment at SLDC, ALDCs and Backup SLDC.

Further for regular maintenance the consumables are required for computer systems, printers

and other equipment

C. Telecom:

The repairs and maintenance cost of Telecom wing is projected due to AMC contracts of OLTEs

and MUXS with different vendors and regular maintenance of Micro wave links.

4.4 Surplus clawed back

There was a surplus of INR 0.68 Crs during the 2nd control period. We propose to pass on this

surplus to the consumers in FY 2014-15.


28

4.5 Operating Charges for Third Control Period: As per the regulation no .1 of 2006 the Operating charges are calculated by following formula

prescribed in the regulation.

Operating Charges (Rs / MW /pm) =( Annual Operating charges/ Total Generating Capacity

(MW) * 12)

The details of the Operating charges as shown in Table 9
