PREFACE
The size of the XI and XII Plans of the Power sector are likely to be
considerably bigger than X Plan. Consequently, the requirement of
electrical equipment and raw materials like steel would be much higher
than in previous Plans. The Sub-Group on Generation Planning of
Working Group on Power for XI Plan has recommended a capacity
addition of around 66,500 MW in XI Plan whereas for XII Plan, the
requirement has been assessed at 86,500 MW.
Such massive addition in power generation capacity would be
possible only if the power/electrical industry also suitably enhances its
manufacturing capabilities to meet this challenge. Other industries like
cement, steel and aluminum also have to augment their production
lines to meet the requirements of the power sector.
With a view to give an idea of the requirement of the power sector
during XI and XII Plan, this booklet giving details of the major electrical
equipment and steel is being brought out by the Central Electricity
Authority.
I am sure this booklet will be found useful by the industry sector in
planning their production capacities in the years to come.

FOREWORD
This booklet is an effort to provide a broad overview of the electrical
equipment and steel requirement during the coming years commensurate
with the power generation and transmission capacity expansion Plans. For
the successful implementation of the power expansion Plan evolved
based on the detailed studies carried out by CEA, it is essential that all the
key inputs required are made available as per the schedule of the
requirement of individual power project. The timely supply of key-inputs is
important not only in the timely completion of the project but also in
avoiding implications of cost over-runs in case the project is delayed. This
assessment would also give appropriate inputs to the manufacturers to
plan and formulate their production targets. Advance action to create
additional production capacity is also important to keep the prices of
manufactured material and equipment in check. This would ensure that
increase in demand does not lead to increase in prices due to mismatch
of demand and supply, as the power sector is highly price sensitive and
concerted efforts from all quarters need to be jointly made to ensure that
prices remain reasonable. This would be instrumental in realizing the
Government's mission of providing power to consumers at a reasonable
price.
Requirement of Electrical equipment is one of the most important
inputs for the development of the Power Sector. In this booklet, an
attempt has been made to assess the requirement of major electrical
equipment for hydro & thermal power stations during the 11th and 12th
Plans. Requirement of equipment has been assessed for different units of
coal and gas based plants i.e. coal handling unit, Ash handling unit,
cooling system etc. In case of a hydro power station, tentative steel
requirement for various Electro-Mechanical equipments/systems and for
civil works has been estimated. In addition, requirement of various
categories of steel for these plants has also been worked out.
Commensurate with the generation capacity addition, the transmission
system requirement has also been worked out and sub-station equipment
and material required has also been covered in this booklet
This book has been prepared by the officers and staff of Planning
wing, CEA with inputs from Thermal, Hydro and Power System Wings. The
various equipment manufacturers such as BHEL, have been duly consulted
for specific equipment based details and requirement of pipes, tubes,
structural steel etc. and others.
It is hoped that the book would serve as a good guide for those
who would plan for future manufacture of equipment for the Power
Sector.

EXECUTIVE SUMMARY
1.
INTRODUCTION
Electricity is a vital input for economic and social development of our society.
Adequate and quality power is essential to fuel this growth and all efforts need to be
made to ensure that all bottlenecks are removed in the path of timely implementation of
power projects and transmission network. The Government’s Mission is to provide
quality and reliable power to all by 2012.
The Installed Generating Capacity in the country which was only 1,358 MW at
the time of Independence has reached a level of 1,27,673 MW, comprising 83,982 MW
thermal, 33,600 MW hydro, 3,900 MW nuclear and 6191 MW from wind and other
renewable energy sources. There has been corresponding growth in transmission and
distribution network too. The target set for capacity addition during the 10th Plan was
41,110 MW. However it is expected that about 30,641 MW would come up in the 10th
Plan out of which about 17,743 MW has already been commissioned till date. As per the
tentative 11th Plan capacity addition programme about 66,463 MW capacity addition is
required during 11th Plan and about 86,500 MW during 12th Plan. Requirement of
electrical and mechanical equipment and other materials needs to be tied up and made
available for timely implementation of these projects.
The Electricity Act 2003 envisages a strong push to the structural reforms, delicensing, thrust on rural electrification, incentives to reforming States and importantly
mandatory metering with stronger provisions for punishment for theft of electricity. The
publication of the National Electricity Policy in February 2005 is an important milestone
as it lays the guidelines and provides direction to the evolution of the Power Sector
within the ambit of the Electricity Act.
The Policy and the Act stipulate that CEA shall prepare the National Electricity
Plan for a short-term timeframe of five year while giving a 15-year perspective and the
various aspects to be covered shall include demand forecast for different regions,
suggested areas/ locations for capacity addition, integration of such possible locations
with transmission system and development of national grid. The National Electricity Plan
has been prepared by CEA and submitted to the Govt. for approval. It is expected that
the Plan will be notified shortly. The Plan covers 10th Plan (2002-07) in detail whereas
perspective planning has been carried out for the 11th & 12th Plans.
For the successful implementation of the power expansion plan, it is essential that
all the key inputs required are made available as per the schedule of their requirement for
each individual power project. Since these are some of the major key inputs, an
assessment of the approximate requirement for the 11th and 12th Plan power projects will
be useful input for the manufacturers and suppliers. In this booklet a broad overview has
been provided about the requirement of electrical equipments and steel during the 11TH
AND 12TH Plan for generation projects and for power system.

Requirement of Equipment & Material for Development of Power Sector
GENERATION CAPACITY ADDITION PROGRAMME
During the 11th Plan, a tentative capacity addition of 66,643 MW is planned
comprising of 17,189 MW of hydro, 46,114 MW of thermal (44,000 MW coal/lignite,
2,114 MW gas/LNG) and 3,200 MW of nuclear capacity. During the 12th Plan, a
tentative capacity addition of 86,500 MW is planned comprising of 30,000 MW of hydro,
44,500 MW of thermal and 12,000 MW of nuclear capacity.
For the purpose of assessing the requirement of equipments, thermal plants have
been categorized into five categories i.e. four categories for coal/lignite plants based on
the unit size of 660/800 MW, 500 MW, 300/250/210 MW and 125 MW, and one
category for Gas based plants. For each of the above category, norms have been drawn up
for the requirement of equipment. However in case of hydro plants no such categorization
is possible as the equipment requirement is site specific and not dependant on the
capacity of the plant. Therefore equipment has been assessed in totality for hydro
capacity of 17,189 MW during 11th Plan and 30,000 MW during 12th Plan. Requirement
of equipment for nuclear plants has not been included in the Report but the steel
requirement for Nuclear power projects coming up in 11th and 12th Plans has been
estimated in this report. It is expected that the Nuclear Power Corporation of India would
separately ensure development of production capability of equipment commensurate with
their requirement during 11th and 12th Plans. However, the nuclear capacity expected in
the 11th and 12th Plans is 3,200 MW and 12,000 MW respectively which is a small
fraction of the total tentative capacity addition during these Plan periods.
During the 11th and 12th Plan, electrical equipment for thermal capacity addition
of 88,300MW is expected to be required. This comprises of coal-based units of about 52
nos. 660/800 MW units, 65 nos. 500 MW units, 59 nos. 300/250/ 210 MW units, 7 nos.
125 MW units and 9 modules of gas turbine stations. Requirement of various electrical
and mechanical components of hydro plants for a capacity addition of about 47,200
during 11th and 12th plan have been assessed. For timely implementation of projects, it is
essential to enhance production capacity to match the requirement.

REQUIREMENT OF ELECTRICAL EQUIPMENTS
In this Chapter, requirement of electrical equipments for hydro and thermal power
projects, along with the corresponding switchyard equipments for different voltage levels,
coming up during the 11th & 12th Plan have been assessed based on certain norms.
Requirement of various types of transformers like GT, ST, UT, ICT etc in the thermal
power plants of different unit sizes have been estimated along with their ratings. Also the
requirement of various types of switchgears, motors, cables etc. required in a thermal
plant have been considered estimated

Requirement of Equipment & Material for Development of Power Sector
The substation equipments have also been estimated as per the transmission
expansion plan for 11th and 12th Plan.
4.
REQUIREMENT OF STEEL
An assessment has been made of the requirement of material specifically different
types of steel for hydro & thermal power plants and power system network planned for
11th and 12th Plan. A detailed exercise has been carried out to assess the requirement of
both type of steel i.e. imported & indigenous. An assessment has also been made of the
requirement of copper and aluminium required for transmission lines.
In case of the steel requirement for 11th & 12th Plan, it has been assessed that
approximately 6 million MT for hydro power projects, 12 million MT for thermal power
projects and 2 MT for Nuclear power projects will be required during 11th & 12th Plan
period. Steel requirement for different constituents of power system like towers,
conductors, earth wires, sub-stations, power transformers has also been assessed. Some
other materials like aluminium for conductors and earth wires, and copper for power
transformers have also been considered. Approximately 5.2 million MT of steel will be
required for completing the transmission expansion planned for 11th & 12th Plan. This
includes about 0.2 million MT of Special Steel- CRGO for power transformers and about
0.67 million MT of structural steel for substations.
Therefore the total requirement of steel has been estimated to be about 25 million
MT for the 11th & 12th Plan.

INTRODUCTION
1. 1 BACKGROUND
Electricity is a vital input for economic and social development of our society.
Besides its importance in the growth of the country’s economy, it plays a major role in
the life of a common man and has a direct impact on the quality of life. Our economy is
growing at a rapid rate with the expected GDP growth rate likely to be over 8% in the
coming years. Adequate and quality power is essential to fuel this growth and all efforts
need to be made to ensure that all bottlenecks are removed in the path of timely
implementation of power projects and transmission network. The Government’s Mission
is to provide quality and reliable power to all by 2012.
1.2 GROWTH IN POWER SECTOR
The Installed Generating Capacity in the country which was only 1,358 MW at the
time of Independence has reached a level of 1,2,423 MW, comprising 83,982 MW
thermal, 33,350 MW hydro, 3,900 MW nuclear and 6191 MW from wind and other
renewable energy sources(As on 31.10.06). There has been corresponding growth in
transmission and distribution network too. In spite of this impressive addition in
generation, transmission and distribution capacity, growth in demand for power has
always exceeded the generation capacity augmentation. As of now the country is facing
energy shortage of 8 % and peak deficit of 12.2%.
The 16th Electric Power Survey has forecast a demand of 1,15,705 MW for the
terminal year of 10th Plan viz., 2006-07. A need-based capacity addition of about 57,000
MW during 10th Plan was required to meet this projected demand in full. However
depending on resources available and status of various projects, the target set for capacity
addition during the 10th Plan was 41,110 MW. Rigorous monitoring of projects was
undertaken by MoP and CEA and the likely capacity addition during 10th Plan is now
expected be about 30,641 MW out of which about 17,493 MW has been commissioned
till date. The 11th Plan capacity addition programme is based on this capacity
materializing during the 10th Plan. However since equipment corresponding to this further
slippage is expected to already have been tied up, this reduction in 10th plan capacity
addition has not been considered while working out the 11th Plan requirement.
The peak demand in the country by the end of 11th Plan (2011-12) is expected to
be 1,51,648 MW whereas the demand by the end of 12th Plan (2016-17) is expected to be
2,05,333 MW as estimated by the 16th Electric Power Survey(with diversity). Studies
carried out by CEA indicate that about 72,000 MW capacity addition is required during
11th Plan taking into account 10th Plan capacity addition of 30,641 MW. However,
depending upon the preparedness of various projects only about 66,000 MW capacity
addition is feasible during 11th Plan in conventional plants by the various utilities and
IPPs. Besides, about 13,500 MW has been programmed from renewable resources as per
the information from Ministry of Non Conventional Energy Resources. In addition to this,
Captive capacity of 12,000 MW is also expected to be commissioned during the 11th Plan.

INTRODUCTION
Central Electricity Authority
Requirement of Equipment & Material for Development of Power Sector
Requirement of equipment and material for Renewable resources and Captive Generation
has not been included in this report. The long term perspective studies for the year 201217 carried out by CEA have indicated an installed capacity requirement of about
2,72,200 MW to meet the 16th EPS demand forecasts with 3.6% inter-regional diversity.
As a result, the additional capacity requirement during 12th Plan works out to be about
86,500 MW. Requirement of electrical and mechanical equipment and other materials
needs to be tied up and made available for timely implementation of these projects.
1.3 REGULATORY & STRUCTURAL REFORMS IN POWER SECTOR
Government of India has been making constant efforts to move away from the
regime of ‘Business As Usual’ to a more pro-active, market oriented approach.
Significant changes have been the entry of private sector in power generation, unbundling
of the vertically integrated business of generation, transmission & distribution and
opening up of transmission & distribution sector for private participation, thus setting a
stage for the quantum jump to realize the capacity addition programme and also making
electricity available to all including rural households.
The Electricity Act 2003 envisages a strong push to the structural reforms, delicensing, thrust on rural electrification, incentives to reforming States and importantly
mandatory metering with stronger provisions for punishment for theft of electricity. The
salient features of the Electricity Act, 2003 are
1.
The Central Government to prepare a National Electricity Policy and Tariff Policy
in consultation with CEA and State Governments.
2.
Thrust to complete the rural electrification and provide for management of rural
distribution by Panchayats, Cooperative Societies, non-Government organizations,
franchisees etc.
3.
Provision for licence free generation and distribution in the rural areas.
4.
Generation is being delicensed and captive generation is being freely permitted.
Hydro projects would, however, need clearance from Central Electricity
Authority.
5.
Transmission Utility at the Central as well as State level, to be a Government
company - with responsibility for planned and coordinated development of
transmission network.
6.
Provision for private licensees in transmission and entry in distribution through an
independent network.
7.
Open access in transmission from the outset.
8.
Open access in distribution to be introduced in phases with surcharge for current
level of cross subsidy to be gradually phased out along with cross subsidies and
obligation to supply. SERCs to frame regulations within one year regarding
phasing of open access.
9.
Distribution licensees would be free to undertake generation and generating
companies would be free to take up distribution businesses.

NATIONAL ELECTRICITY POLICY AND PLAN
The Electricity Act 2003 mandates that the Central Government shall prepare the
National Electricity Policy and Tariff Policy in consultation with the State Governments
and CEA for development of the Power System based on optimal utilization of resources.
The publication of the National Electricity Policy in February 2005 is an important
milestone as it lays the guidelines and provides direction to the evolution of the Power
Sector within the ambit of the Electricity Act.
The main objective of the National Electricity Policy is to make electricity
accessible to all households in next five years(2010) and to facilitate demand to be fully
met by 2012. International standards in reliability and quality of Power are to be achieved
by this timeframe. At present the per capita consumption of the country is about 631
units. Even though simultaneous efforts are being made to achieve high levels of energy
efficiency through energy conservation measures, it is endeavoured to increase the per
capita consumption, which is synonymous with progress and development, to 1000 units
by 2012.
The Policy also stipulates that CEA shall prepare the National Electricity Plan for
a short-term timeframe of five year while giving a 15-year perspective and the various
aspects to be covered shall include demand forecast for different regions, suggested areas/
locations for capacity addition, integration of such possible locations with transmission
system and development of national grid.
The National Electricity Plan has been prepared by CEA and submitted to the
Govt. for approval. It is expected that the Plan will be notified shortly. The Plan covers
10th Plan (2002-07) in detail whereas perspective planning has been carried out for the
11th & 12th Plans.

CHAPTER-2
GENERATION CAPACITY ADDITION PROGRAMME
The Electricity Act 2003 and the National Electricity Policy announced by the
Government in February 2005 stipulates that CEA is to prepare the National Electricity
Plan. This Plan shall provide the blueprint for the development of the power sector.
Accordingly, CEA has prepared the Plan which, after approval of the Government, shall
be notified for reference of all Stakeholders.
The National Electricity Plan has been prepared based on detailed studies carried
out by CEA. The 10th Plan has been covered in detail furnishing project wise details of
target as well as the likely capacity addition along with status of each project. Perspective
planning has been carried out for the 11th and 12th Plans. As per the latest review of the
status of 10th Plan projects the likely capacity addition is about 30,641 MW, this further
slippage shall not change the 11th plan requirement as the equipment and material for
these projects is expected to already have been tied up.
In the National Electricity Plan a number of generation capacity expansion plans
have been worked out. These are - Desirable Scenario i.e. Scenario with no limitation on
hydro and gas based capacity, Low hydro Scenario, Limited gas Scenario, Most feasible
Scenario i.e. low hydro and limited gas scenario, 7%, 8% and 9% Energy Growth Rate
Scenarios. However in this booklet, the requirement of equipment and steel has been
worked out corresponding to the Most feasible Scenario and demand as per the 16th EPS
Report.
In this Chapter, details of tentative capacity addition during 11th & 12th Plan have
been furnished. For the purpose of assessing the requirement of equipments, thermal
plants have been categorized into five categories i.e. four categories for coal/lignite plants
based on the unit size of 660/800 MW, 500 MW, 300/250/210 MW and 125 MW, and
one category for Gas based plants. For each of the above category, norms have been
drawn up for the requirement of equipment. However in case of hydro plants no such
categorization is possible as the equipment requirement is site specific and not dependant
on the capacity of the plant. Therefore equipment has been assessed in total for hydro
capacity of 17,189 MW during 11th Plan and 30,000 MW during 12th Plan. Requirement
of equipment for nuclear plants has not been included in the Report as their requirement,
which includes special type of material, is difficult to estimate. Also it is expected that the
Nuclear Power Corporation of India would separately ensure development of production
capability for material and equipment commensurate with their requirement during 11th
and 12th Plans. However the nuclear capacity expected in the 11th and 12th Plans is 3160
MW and 12000 MW respectively which is approx. 12 % of the total tentative capacity
addition.

SUMMARY
In this Chapter, details of tentative capacity addition planned for the 11th and 12th Plans
have been furnished. Further, to facilitate assessment of requirement of equipment and
material corresponding to this capacity addition, categorization of thermal capacity has
been done. In case of thermal capacity, the details of categories and the number of units/
modules in each category tentatively planned for the 11th and 12th Plans have been
furnished in his Chapter. However, hydro plants have not been categorised and
assessment has been made for the total number of hydro projects. Requirement of nuclear
capacity has not been included. Corresponding to the tentative capacity addition during
11th and 12th Plan and the number of units/ modules in each category, the requirement of
equipment and material has been worked out in Chapters 3 and 4.

REQUIREMENT OF ELECTRICAL EQUIPMENTS
In this Chapter, the requirement of electrical and mechanical equipments has been
assessed for power generation stations, both hydro and thermal plants, as well as for
power substations. This requirement has been worked out corresponding to the tentative
capacity addition during the 11th and 12th Plans.
Equipment for nuclear stations has not been considered as the same is separately
expected to be done by Nuclear Power Corporation. Also the requirement of equipments
and materials for nuclear plants is difficult to estimate which in any case is expected to be
3200 MW and 8800 MW in the 11th and 12th Plans respectively and therefore a small
fraction of the total tentative capacity addition.
3.1
REQUIREMENT OF ELECTRICAL EQUIPMENTS FOR GENERATION
PLANTS (INCLUDING SWITCHYARD EQUIPMENT)
The estimated requirement of electrical equipments for generation plants coming up
during the 11th Plan and 12th Plans has been worked out considering tentative capacity
addition identified for these Plans, details of which have been furnished in Chapter 2.
Thermal projects for commissioning during the 11th and 12th Plan have been categorized
in five major groups on the basis of their unit sizes. In case of thermal plants, requirement
of major electrical equipment has been worked out for one unit of each of these categories
and subsequently depending on the number of units in the respective categories, the total
requirement has been assessed for 11th and 12th Plans. In case of hydro units such
categorisation is not tenable since each project is site specific and therefore the total
requirement of major equipments has been worked out for the 11th and 12th Plan.
Switchyard equipment at the generating stations has also been included. Details of the
above assessment are given below.
3.1.1 Thermal Power Plants (Including Switchyard Equipment)
The thermal plants have been categorized into five categories based on the unit size
i.e. 660/800 MW, 500 MW, 300/250/210 MW class and 125 MW for coal/lignite plants,
and gas/LNG modules. In case of Gas/LNG based power projects, numbers of
modules( comprising of 2GTs and 1 ST) corresponding to each project have been
assessed for 11th & 12th plans separately and as per the norms of equipment required for a
typical 360 MW gas module, the total requirement of electrical equipment has been
assessed. The requirement of electrical equipments for switchyards at the generating
station has also been indicated.
i)
Item wise requirement of equipment for 660/800 MW category of thermal
plants during 11th and 12th Plans is given in Table 3.1.

vii) Requirement of Switchyard equipments for different voltage levels corresponding to
the unit size of each generation project have been assessed. For projects having unit size
of 800 MW, switchyard equipments at voltage levels 765 kV and 132 kV have been
considered. Similarly, for projects having unit size of 660 MW and 500 MW, switchyard
equipments at voltage levels 400kV and 132 kV have been considered. For projects
having unit size of 300/250/210 MW & Gas modules having unit size of 360 MW,
switchyard equipments at voltage levels 220 kV have been considered. For projects
having unit size of 125 MW requirement of switchyard equipment has not been
considered since it would normally be at a voltage level of lesser than 132 kV.
For assessment of electrical equipments for switchyard of generating stations, 6
bays have been considered for each coal/Lignite based project, and 8 bays for each
module of gas project.
The layout of the substations has been considered according to the prevailing
practice for respective voltage levels. A Breaker and a half scheme has been assumed at
765 kV & 400 kV levels. For 220 kV level, Double main and transfer bus scheme has
been assumed. Main and transfer bus scheme has been assumed at 132 kV.

The broad basis followed in the estimation of the other components of hydro
projects for 11th & 12th Plan is as under.
i)
Gates & Hoists: The number of radial gates roughly varies between 3 & 14
numbers depending on type of hydro scheme. Number of Gates depends on
length of dam and type of scheme i.e. storage scheme or Run-of-River schemes.
The number of spillway radial gates is more for storage scheme compared with
ROR Scheme.
ii)
Vertical Lift Gates: Vertical gift gates are normally installed for overflow
spillway, intake structures, desilting chamber outlets, surge shaft outlets, draft
tube, tail race outfall etc. Depending on type of scheme it may vary between 5 &
20. For ROR scheme with HRT, the number of vertical lift gates is more
compared with storage scheme.
iii)
Hydro Turbine and Auxiliaries (Motors plus Control Centres): One set of
Turbine and auxiliaries have been considered for each unit. The MW output
rating of turbine shall match unit rating.
iv)
Main Inlet Valve (MIV): Generally, One MIVS in each unit is provided in
penstock except for low head HE schemes/Dam Toe HE Schemes.
v)

considered for each Generating Unit.
viii)
Dynamic Braking Equipment: Dynamic braking equipment is generally
provided with large hydro generating units with high speed machines. The
number has been estimated accordingly.
ix)
Unit Control Board (UCB): One set of UCB is considered with each generating
unit.
x)
Isolated Phase Bus Duct and terminal / tap-off of equipments: The length of
IPBD depends on layout of power house and varies from scheme to scheme. The
estimation is based on experience.
xi)
11kV/13.8kV/24kV CT’s: Number of CT’s depends on protection and metering
scheme of particular plant, however, for estimation purposes 10 to 19 CT'’ per
phase per unit has been considered depending on unit size.
xii)
Neutral Grounding Cubicle: One set of Neutral grounding cubicle is considered
for each generating unit.
xiii)
132kV/220kV/400kV Generator Transformers: The MVA Generator
transformer rating is normally taken as 110% of generator rating, the same has
been considered in estimation.

considered for under-ground 220kV / 400kV switchyard, while conventional
outdoor switchyard for surface / semi underground schemes.
xvii)
EOT Cranes: The total installed tonnage capacity of EOT cranes is based on
broad estimation of stator and rotor weights, though these weights may vary
drastically even for machines of similar rating.
xviii) EHV, XLPE cables, EHV Bus Duct: The cable requirement depends on layout
of power house and varies from scheme to scheme. The estimation is based on
experience.
xix)
Unit Auxiliary and Station Service Transformers: The total capacity of unit
and station auxiliary transformers has been considered as 1.2% of installed
capacity.
xx)
11kV Switchgear Board: The 11kV switchgear boards vary from station to
station depending on 11kV scheme. However for estimation purposes two LT
boards per unit has been considered.
xxi)
Power and Control Cables: There is no set rule for estimating power and
control cable lengths as it depends on layout and control philosophy. The
estimation is based on experience.
xxii)
110V/220V DC System (Batteries, Charger and DCDB): The battery capacity
varies between 400AH to 1800AH, and battery chargers from 2 to 4 numbers
depending on number of units and total installed capacity.
xxiii) Grounding System: The total tonnage of grounding material vary from station to
station depending on layout of power plant, fault level, soil resistivity etc.
xxiv) DG Sets: The MVA capacity on DG sets for HE plants vary between 500KVA to
2000KVA depending on requirements worked out during detailed engineering.

CHAPTER –4
REQUIREMENT OF STEEL FOR 11TH AND 12TH PLAN
In this Chapter, an assessment has been made of the requirement of material
specifically different types of steel for hydro & thermal power plants and power system
network planned for 11th and 12th Plan. A detailed exercise has been carried out to assess
the requirement of both type of steel i.e. imported & indigenous. An assessment has also
been made of the requirement of copper and aluminium required for transmission lines.
These details shall provide valuable inputs for equipment and material manufacturers and
guide them to plan their production capacities accordingly.
In case of thermal power stations, steel requirement for different units of
generation plants i.e. boiler, coal handling unit, ash handling unit, condenser, pulveriser
etc has been estimated.
For a hydro power plant, estimation has been done for steel requirement in civil
works as well as electro mechanical equipments/systems in the power house.
Transmission system requirement corresponding to the planned generation
capacity addition has also been worked out. Material requirement for this transmission
system, including generation switchyard, substation and transmission lines, including
towers, line conductors & earth wires have also been assessed in this Chapter.

4.1.2 Thermal Power Plants
Requirement of steel (Imported & Indigenous ) for thermal power projects coming
up in 11th Plan is calculated on the basis of detailed steel requirement for typical 2x500
MW coal based unit , provided by BHEL (Given in Appendix 1).
For Coal/Lignite based projects, steel requirement per MW has been worked out
and based on this per MW norm, the requirement of steel for the total coal based thermal
capacity has been assessed. For gas based projects, norms for steel requirement per MW
have been assumed to be 50% of coal based project for the applicable items as has been
noted in case of past installations. Also in case of gas based plants items such as furnace,
coal handling plant, Electrostatic precipitators etc. are not required and hence have not
been considered.
During 11th Plan, total thermal capacity addition planned is 46,114 MW
comprising of about 44,000 MW of coal/lignite based plants and 2114 MW of gas based
plants. Similarly for 12th Plan, thermal capacity addition planned is 44,500 MW.
Details of steel requirement for different equipments/ systems for the 11th and 12th
Plan coal based thermal projects are furnished in Table 4.3.

As evident from above, for 11th Plan, approximately 58,55,582 Mt of steel is expected to
be required for the planned thermal projects. Similarly, approximately 58,11,745 MT of
steel is expected to be required for the thermal projects coming up in 12th Plan.
4.1.3 Nuclear Power Projects
Assessment of steel for Nuclear Power Plants is based on requirement of steel for coal
based plants. In case of nuclear plants, need for steel for coal handling system, boiler,
ESP etc is eliminated whereas amount of steel for turbine etc. is increased. Assuming the
effect of these two factors approximately equal, the norms for the steel requirement for
nuclear power plants is taken to be same as that of coal based plants.
Considering the above, the steel requirement for Nuclear Projects is as under:
