Gist of Discussions held in a meeting on
28th January 2015 for providing reliable telecommunication at
66 kV & 33 kV voltage level substations
To provide reliable communicating facilities at 66 kV & 33 kV voltage level substations in all
States/UTs, a meeting with the State/UT utilities was taken by Chairperson, CEA on
28/1/2015 in NRPC Conference hall, Katwaria Sarai, New Delhi -110016.
List of participants is enclosed at Annex-IA. The list of Nodal officer from Chhattisgarh,
Punjab, Bihar, DNH, Kerala, Nagaland and West Bengal, as collected in the meeting is
enclosed at Annex-IB.
Chairperson, CEA, welcomed the participants and initiated the discussion. He stated that
during recent devastation caused by cyclonic storm Hudhud in Visakhapatnam, and Odisha
state, failure of communication system affected restoration of essential services. Member
(GO&D), CEA had taken meeting on this subject on 11th & 12th Dec., 2014 and it was
decided that States/UTs would prepare DPR in regard to providing Optical Fiber
Communication (OFC) at 66 kV & 33 kV substations. The status/clarifications in preparation
of DPR is the agenda for the meeting. He clarified that MOP has decided that provision of
OFC upto 132 kV would be taken care of by PGCIL; and CEA would coordinate for provision
of OFC at 66kV & 33kV voltage level.
Member (GO&D), CEA stated that optical fiber connectivity at 33kV / 66kV substations would
enhance redundancy in day to day operation besides help in early restoration in times of
natural calamities. He stated that OFC should not be used for voice communication only but
transmission of data under SCADA should also be used. All new substations below 132 kV
should have optical fiber connectivity. For providing optical fiber to the existing substations,
States should explore all possibilities to tap fiber available at nearest source like GP (Gram
Panchayat), BSNL exchange in Block, overhead fiber, etc. Central Government Schemes “Integrated power Development Scheme” (IPDS) and “Deendayal Upadhyay Gram Jyoti
Yojna” (DDUGJY) provide an outlay of Rs. 120 Crores and Rs. 280 Crores respectively for
establishing missing link of optic fiber (up to substation from National Optical Fiber Network).
PFC & REC are the Nodal Agencies. He urged that the States/UTs can make use of these
two Central Govt. schemes for establishing optic fiber connectivity.
Chief Engineer (LD&T), CEA, stated that for use under contingency situations such as
cyclone, flood, earthquake etc., V-SAT communication should be provided at 33 kV and
higher voltage level substations. These could also be used for SCADA, as being
successfully implemented in Karnataka. Each State depending on requirement should
procure adequate number of V-SAT mobile vans also, so that emergency situations could be
handled effectively. He stated that there are about 27000 nos. 66 kV & 33 kV substations
which are mostly in interior parts of the States where BSNL network is available. Considering
this, a scheme is proposed (at Annex-II) for discussion.
PGCIL sought following details to facilitate preparation of DPR by them for communication
system from 132 kV and above voltage sub-stations level:
a) List of 132 kV and 220 kV sub-station existing in various States as on date.
b) Transmission lines connectivity of these 132 kV and 220 kV stations and their
distances.
c) Map showing all these stations for exploring redundancy in connectivity.
d) Earth wire details of transmission lines to assess suitability for OPGW (As per
Annexure-III)
PGCIL stated that above details are required urgently for preparation of DPR and requested
the concerned officials to furnish these details within a weeks’ time to PGCIL so that
Feasibility Report for 132 kV level and above is finalized expeditiously.
BSNL agreed that a list having details of state-wise BSNL Nodal Officers would be handed
over to CEA soon. Similarly, States/UTs would also furnish details of their nodal officers.
Each State utility would furnish details of 66 kV & 33 kV substations to BSNL Nodal officers
who in turn would establish feasibility of OFC provision from nearest fiber source and hand
over the same to the concerned state utility. BSNL feasibility report would contain all details
like length of fiber requirement, terminal equipment, cost, bandwidth, etc. and it would act as
input for the States to prepare DPR. PGCIL agreed to extend assistance (like sharing of old
DPR, etc.) to the States, if required, for preparation of DPR.
Karnataka stated that DPRs prepared by each DISCOM would be routed through STU
before handing over to REC & PFC with a copy to Chief Engineer (LD&T), CEA. It was
decided that rural and urban substations may be segregated in the DPR for fund assistance
in DDUGJY and IPDS schemes respectively. OPTCL has emailed its OPGW status and the
same is enclosed at Annex-IV.
Regarding reliability of BSNL network, BSNL informed that they would be the sole agency in
laying and maintenance of optical fiber. Keeping requirement of power sector, they would
make all efforts to provide higher level of services. However, utilities may keep backup
provision as well. Regarding tariff mechanism, BSNL stated that possibilities of customized
competitive tariff plan would be explored.
Some utilities like BSES in Delhi stated that they have their own rugged communication
network at 66 kV & 33 kV voltage levels. It was decided that such utilities which have their
own reliable communication network at 66 kV & 33 kV voltage level and therefore do not
wish to prepare DPR are required to send confirmation in this regard to Chief engineer,
LD&T, CEA.
Punjab stated that they have 850+ nos. 66 kV & 33 kV substations whose data would be
required to be shared with BSNL. He suggested their state may be allowed to create their
own network. Further, he suggested that one sample DPR may be prepared. It was clarified
that assistance from PGCIL may be taken for DPR preparation; regarding having own
network, it was stated that network owner is not important, what is important is availability of
reliable communication network and State is required to confirm the same.
Uttarakhand informed that there are 289 nos. of 33 kV & 66 kV substations in the State. 114
nos. are in Urban areas and 175 nos. are in Rural area. He informed that they had compiled
the information and sent to the concerned agencies. It was clarified that based on discussion
and decisions taken in the meeting, Uttarakhand is to take action and prepare DPR
accordingly for further submission.

ANNEX-II
PROPOSED LAYOUT PLAN FOR OPTICAL FIBER COMMUNICATION (OFC) FOR 66KV &33KV SUBSTATIONS
Note:
1) All GPs (Gram Panchayats) are proposed to be connected via BSNL network having bandwidth upto 100
Mbps.
2) Keeping 27000 nos. of 33 kV & 66 kV substations into consideration, 100 no. (approx.) of substations might
be kept under one ALDC (Area Load Despatch Centre). However, exact no. of 33 kV and 66 KV substations
to be kept under one ALDC would be decided by individual States based on their requirement.
3) On 132 KV and 66 KV power lines, OPGW (Optical Ground Wire) is feasible and accordingly fibre optic cable
layingcan be done.
4) In states where ALDC is provided, only a subset of data would flow from ALDCs to SLDC. In smaller states
like Manipur, data would flow directly from substations to SLDC.

FEASIBILITY CUM DETAILED PROJECT REPORT FOR
Establishment of Fibre Optic Communication System in Eastern Region
1.0
BACKGROUND
a) Electricity plays an important role in the overall economic development of the country. In
the last six decades, since independence, Indian Power Sector has achieved phenomenal
growth from a few scattered small generators supplying load to local process of elite
customers, to strong Regional Grids spanning throughout the length and breadth of the
country, and supplying to even remote corners of most of the States. The achievement of
increasing the installed power capacity from 1362 MW to over 1,73,626 (as on 31.03.2011)
MW along with development of EHV Transmission System of 765 /400/220 kV has made it
possible to provide electricity to cities, towns, industrial areas and the remote villages.
Considering the complexity & growth of Power System, need of effective management of
Power System were felt essential. Accordingly, Unified Load Dispatch & Communication
Projects (ULDC) was established on Regional basis for providing advance EMS/SCADA
and Communication System for Management of Regional Power Grids. These ULDC
Projects were commissioned progressively from July 2002 to February 2006 in Southern,
Northern, North-Eastern, Eastern & Western regions. Subsequent to commissioning of
ULDC Schemes in all the regions and formation of NEW Grid with the synchronization of
Northern, North-Eastern, Eastern & Western grids and increase of Inter-Regional Power
Exchange to around 22400 MW as of now, National Load Dispatch Centre (NLDC) at apex
level has been established to coordinate Inter-Regional and Inter-National Power
Exchanges and monitoring the Power situation at national level for ensuring security to
National Power Grid.
b) Under Eastern Region ULDC Project, Communication Network comprising of Microwave
(MW), Fiber Optic (FO), PLCC based communication Network was established to support
data and voice requirements of SCADA/EMS Projects.
The EMS/SCADA system and wideband communication system established under Eastern
Region ULDC Project is as below:

It may be mentioned that in Eastern Region a scheme for replacement of existing Micro wave
communication links with Fiber optic based Communication system is under awarding stage
based on approval of ERPC and is likely to be completed by June 2013.
In the 17th ERPC meeting, it was deliberated that with fast growing expansion of Power System
and considering the technological requirement such as Special Protection Scheme, Phasor
Page 1 of 16
Measurement Unit etc., it would not be possible to meet the Communication requirement for
such applications through PLCC system. Further, in order to facilitate the voice and data
connectivity of POWERGRID stations with RLDCs in accordance with IEGC and also
considering technological requirement referred above, need of expansion of existing wideband
communication system is felt essential. This will facilitate connectivity of other users with data
collection points on CTUs system as envisaged in IEGC.
Accordingly, POWERGRID proposed a scheme of fibre optic based communication network
consisting of approximately 3643kms of OPGW cable at an initial estimated cost of Rs. 69
crores for providing voice and data connectivity of requisite central sector, SEBs substations
and IPPs generating stations. The scheme was approved in following two RPC meetings as
detailed below:
(i) The scheme was approved for 2588 kms of 24fibre OPGW cable along with
communication equipments with initial estimated cost of approximately 49croresin the
17th TCC/ ERPC meeting held on 16th & 17th March, 2011.
(ii)
The scheme was approved for 1055kms length of OPGW cable with an initial estimated
cost of approximately Rs. 20Crore in the 15th TCC/ERPC meeting held on 27th & 28th
Sept.2010.
It has also been approved that investment made on the same shall be recovered through tariff
to be determined by CERC. Further, in the meeting it was also agreed that POWERGRID shall
suitably keep the clause of quantity variation in case WBSETCL carry out some work of its own
before commencement of POWERGRID’s work. The copy of the minutes of the meeting is
enclosed at Annexure-I. During implementation, if any requirement of constituents received
shall be suitably taken care.
2.0
JUSTIFICATION
Subsequent to commissioning of ER-ULDC project, considerable number of EHV
Substations and Power Plants has been commissioned in Eastern Region but the
Wideband Network has not been expanded.
Power system communication requirements are reliability, availability and security of the
highest order. Past experience shows that fiber optics installed on Overhead Power lines is
the most reliable form of communication medium due to least amount of down time. Hence
an expansion of Fiber Optic based System is considered essential to meet the power
system communication requirements.
Though power system network has expanded very fast in the last few years and several
EHV substations are planned to be added in the network due to government emphasis for
accelerated development of the power sector and addition of generating capacity through
Ultra Mega Power Projects (UMPP), IPPs and Public Sector companies. The new
substations integrated to the SCADA system of ER-ULDC project are communicating to the
control centers on PLCC. The PLCC based communication system has limitations in regard
to data communication as the performance of this system deteriorates after two hops.
Further, due to frequency congestion only limited number of channels can be provided on
PLCC. Therefore, it is essential that in order to provide reliable and efficient communication
network to the fast growing power system network, existing FO Communication Network is
to be expanded to cater for additional Wideband Nodes in the Communication Network of
ER-ULDC project.
Power System in the country is expanding very fast and with increased number of
interconnections between Regions, many new technologies are being implemented. In
addition, Indian Grid is characterized by wide variation of Power flow due to variation in
Page 2 of 16
demand / generation during day / seasons. Further, consumer aspiration for quality and
reliable power supply is increasing. All the above, with increasing complexity of Grid
operation manifold, necessitates dynamic monitoring of Grid parameters / conditions on
real-time basis. The existing SCADA/EMS provides the data which are steady state in
nature and not suitable for dynamic monitoring and control for the Grid due to high degree
of latency of tele-metered data and also non-synchronized sampling of data. Emerging
technologies like Phasor Measurement Unit (PMU), Wide Area Measurement (WAM)
system provide dynamic monitoring of network on real time basis. Such monitoring through
the said measurements shall facilitate development of various control, regulation and
preventive features like Remedial Action Schemes (RAS), System Integrated Protection
Scheme (SIPS), Adaptive islanding, Self-healing Grid etc. These technologies have been
envisaged in the GoI report of Working Group on power for 11 th Plan as well as National
Electricity Plan – Transmission. Relevant extract of the report is enclosed at Annexure-II It
is expected that such emerging technologies would be deployed for development of Smart
Grid as soon as they are available in the market. These emerging technologies would
require communication system with least latency and high reliability. The OPGW based
Fiber Optic based communication system would be most suitable for such applications. The
proposed FO network would be used for such upcoming advanced technologies also.
In essence need of wideband communication system can be summarized as follow:
(i) Expansion of Power Sector is taking place at a very fast pace leading to establishment of
IPPs, UMPPs, High Capacity Transmission System etc. This effectively means that the
no of substations and power plants requiring data & voice connectivity with the ERLDC
is increasing manifold.
(ii) The Utility of SCADA system has been realized by system operators and users are
asking for a very reliable system which is not possible without robust and reliable
communication system.
(iii) Due to expansion of Power System it is not possible to meet the communication
requirement with PLCC. POWERGRID transmission lines are being made LILO
frequently due to open access which disrupts the communication system based upon
PLCC as LILO increases no. of PLCC hops and more no. of PLCC hops deteriorates
the performance of PLCC communication.
(iv) The proposed communication network is to be used by all agencies connecting to grid
under control area of RLDCs. This ultimately results in more no of substations and
power plants using the communication network of power sector.
(v) With increasing complications in the power system, in order to ensure effective grid
operation in case of contingencies, the need of special protection schemes (SPS) is
being felt by the grid operators. These SPS requires the transfer of signals from one
node to many nodes simultaneously. Since these are contingency provisions there
effectiveness is of paramount importance. SPS can work effectively only when reliable
wide band network is available.
(vi) Wide Area Measurement System (WAMS) is the new emerging technology for grid
operators; PMU (Phasor Measurement Unit) is the basic building block for WAMS to be
installed at the Substations and Power Plants. The PMUs generate large volume of data
and if the data of all the feeders with higher sampling rate is to be accommodated, each
substation would require up to 2 Mbps bandwidth for PMU data alone. WAMS based
systems can be implemented with Fiber Optic based communication network only.

(vii) Line Protection: For shorter lines current differential protection along with distance
protection is preferred as this ensures two line protections on two different principals
which is considered a better protection philosophy. The available current differential
protection relays exchange the current signals (the data such as magnitude of voltage
& current, displacement angle etc.) between the two ends of a line on dedicated fibers.
Further, the lines are being frequently LILO, many times resulting into smaller lines.
The availability of fibers would make it possible to implement current differential
protection on the lines.
(viii) Due to fast expansion of Power System it is getting increasingly difficult to provide
PLCC for protection and speech for new lines due to frequency congestion. FO based
communication network shall help in overcoming this problem.
(ix) Many of the central sector stations are being operated from remote and remote
operation of all the substations of POWERGRID is being planned. Presently PLCC
communication is being used for remote operation which is not very reliable, the
expansion of wide band network shall ensure effective remote operation of the existing
as well as new substations.
Accordingly, FO network has been finalized considering this aspect. The existing ER-ULDC
network, FO project in lieu of MW replacement and final FO network proposed for
implementation under Master Communication Plan is attached at Exhibit-1.0.
Previous experience shows that additional capacity available on FO network could be
utilized commercially by offering the same to the telecom service providers, the FO network
envisaged under this feasibility report would also provide the similar opportunities but the
extent of such usages would depend upon the market conditions prevailing at the time of
completion of the network. However, it may be mentioned here that as per ERPC approval,
the proposed facility shall be used by electricity sector only. If and when, in future,
POWERGRID wishes to utilise this facility for its commercial business through Telecom
Department, the matter would be suitably taken up with ERPC for approval of the same.

9.3
Design Criteria
High system availability, reliability and flexibility in maintenance of the system are the main
criteria for design of any communication network. Principally these are described as
follows:
(a) High Reliability: The system should be engineered to provide high reliability with
minimum loss of communication by selecting proven hardware and using proven
methods of communication.
(b) High Availability: The system should suffer only minimum degradation in the event of
circuits failing due to media shortcomings, and care should be taken to provide
alternative route of speech & data wherever it is economically feasible.
(c) Rapid Response: The system should offer quick response to changes in measured
values by keeping the update time within specified limits.
(d) Economy: The system should be engineered to provide the required performance in an
economical manner.
(e) Flexibility: The communication network should have enough flexibility to changed
requirements and future augmentation programs. The network should itself be capable
of being easily changed to embrace these new requirements.
(f) Maintainability: The network should use methods which make minimum demands for
maintenance. Also, adequate provision of spares should be allowed to ensure quick
remedial action of any fault at any station within the network.
The communication network under the proposed project shall have the following aspects in
order to meet the high reliability, availability and maintainability criteria:
(i) The proposed FO based communication network shall be primarily used for speech and
data communication to cater SCADA/EMS and associated systems, Special Protection
System, Wide Area Measurement Systems, Remote Operation etc. to efficiently operate
the large and interconnected Power System. Presently large no of RTUs installed at the
substations are communicating to the control center on PLCC at least for a portion of the
communication route. The performance of data communication over PLCC is not
satisfactory when the data transmission involves more than two hops, this problem is
further aggregated on aged lines of constituents due to high noise occurring out of poor
maintenance.
Page 8 of 16
(ii) The Fiber Optic cable to be laid shall have 24/48 fibers, which will ensure the continuity
of the link over a longer period as spare fibers can be used to replace the damaged
fibers at any point of the time during its design life time. The spare fibers can also be
used by telecom services which would generate additional revenue. However, this would
depend upon the prevailing market conditions at particular point of time.
(iii) The Fiber Optic (FO) terminal equipments to be installed under the project shall be
based upon SDH technology and will have at least STM-16 capacity. The interfaces
shall be selected meeting the present requirement and considering the forthcoming
developments in control center technology for grid management etc. The SDH
equipment shall be provided with redundancy to ensure path protection and against
failure of any interface card/power supply.
(iv) For longer lines (>250kms) if the output of FO terminal equipment does not meet the
link budget requirement, repeater may be required which shall be installed at the
substations.
(v) Primary multiplexers shall be provided at the new wide band locations. Each of these
primary mux shall have 2 Mbps capacity. Suitable interface cards shall be provided to
meet the present and future requirement for data transmission and interfacing with
digital and analog PLCC equipment as well as with data transmission equipment such
as RTU and sub-station automation system.
(vi) For ease of maintenance, configuration changes and centralized monitoring in the
equipment the Network Management System (NMS) shall be provided for Fiber Optic
Terminal Equipment as well as for primary multiplexers.

objectives:
i)
ii)
iii)
iv)
v)
To group related functions together to have clearly defined 'Roles' for the relevant
'functional heads'.
To have well defined 'Responsibility & Authority' centers in the structure.
To have well defined 'communication channels' and optimum 'span of control' in the
organization.
To have optimum manpower.
To have decentralization of activities as far as possible.
At the first level in the organization, Corporate Centre will be planning, monitoring and
controlling the objectives and activities of the organization. At the second level, the
Regional HQs will be playing the role of controlling the activities in the regions and will
report to Corporate Centre. In POWERGRID, nine regions have been identified as NR-I,
NR-II, SR-I, SR-II, WR-I, WR-II, ER-I, ER-II & NER, and these regions are headed by
GM/ED. At the third level in the structure, the Substation Groups will be controlling the
activities of the respective Substation and associated lines under that Group and will report
to the Regional HQs. The Groups will consist of basic working units such as sub station
Construction/maintenance, line construction/maintenance. The Groups will have both
service and technical functions, to cater the basic functional requirements. In regard to
work related to ER-ULDC system, ER-1 and ER-2 regions are responsible for the

10.2
Project Management
The project of Fiber Optic based Wideband Communication system will be planned,
implemented, monitored and controlled through Integrated Project Management and
Control System (IPMCS). IPMCS uses PERT/CPM technique as the basic management
tool. For effective project planning and review, three tier level of planning and review have
been adopted.
Level-I:
Planning is done by the central planning cell, which is in the form of an overall project
schedule called the Master Network, for the project which forms the basis for all subsequent
planning and monitoring of the activities. This covers broadly all the packages of project
and indicates activities of engineering, contracts, manufacturing, erection and
commissioning. The Master Network is prepared using computerized techniques which
subsequently helps in comparing the actual progress of the project with the scheduled
progress. This gives indication of the likely critical areas and helps in preventing the same,
thereby resulting in smoother implementation. The Master Network also acts as a source
for the planning to be done at Level - II & Level - III.
Level-II:
Planning is done package-wise and is worked out and finalised with the respective
contractor/vendor during the pre-award stage. Level II networks are made within the
milestones identified in the project Master Network (L-I).
Level-III:
Plans deal with elaborate schedules and weekly/monthly rolling plans which are prepared
for activities of engineering, supply (as the case may be) & field activities. These form the
basis of monitoring by the various functions.
The system envisages monthly review of the level II programmes with contractors and at
field on a weekly basis.
A site monthly progress report is sent to the head office having four sections, i.e.

14.0 PAST RECORD OF SUCCESSFUL PROJECT IMPLEMENTATION
POWERGRID has built around 20,733 Km of FO based communication network by
installing the FO cable on POWERGRID and state utilities’ transmission lines under ULDC
projects and under POWERGRID’s Business Telecom Network. This network is in
successful operation. The state portion of the network is also being maintained by
POWERGRID on their behalf. As on March 31, 2011, POWERGRID operates about 82354
ckt. kms. of transmission lines and 135 Sub-stations with a transformation capacity of over
93050 MVA. POWERGRID has maintained the transmission systems availability over 99%
consistently.. POWERGRID has team of dedicated experts in the field of engineering for
Load Dispatch and Communication facilities comprising of SCADA/EMS system and
Telecommunication Systems, substation and Transmission Line Engg equipped with stateof-the-art technology, software capabilities and computer aided facilities for Planning,
Design, Operation and Maintenance of Load Despatch & Communication facilities and
transmission system. It has a well established system of continuous feedback from the field
and upgrades the system accordingly.
Load Dispatch and Communication facilities involve the technologies which are fast
developing and have comparatively short life cycle. The control center requirements are
also changing due to regulatory changes such as implementation of ABT, Open access,
desirability to declare spare transmission capacity etc. Based on the development on
technology front and the feedback from the grid operators as well as in pursuit to
economize the cost and implementation period, its experts are vigorously pursuing the
developments on technical and operational fronts and systems are designed considering
these developments.
POWERGRID has developed a project monitoring system matching with the organization
structure, complexity / intricacies involved in the project implementation and Management
information system. The system calls for increasing details of planning in all the facets of
functions such as engineering, contracts, site and corresponding levels of monitoring and
control, for generating a management summary report to the top management. This
management summary report highlights the project completion trends, actions being
taken/to be taken for the attention of the top management on exceptional basis of critical
areas.
Further, the monitoring system envisages a regular total project review called project review
meeting (PRM). This review meeting is headed by Regional in-charge with representation
from all functions viz. Contracts, Engineering, Field, Personnel, Finance, Corporate
Monitoring Group, etc. The participants discuss project critical, project interface problems
and project completion trends, etc.
Page 13 of 16
From the discussions held during the PRM emanates a status report and also an exception
report put up to the Chief Executive and Directors which highlights extremely critical areas
needing immediate attention and assistance required. Once in three months the PRM is
held at Corporate Centre. These discussions help in identifying the critical areas and
seeking decisions for speedy project implementation.
