Summary .
eforming Indian Railways has been
identified as a key priority by Hon'ble
Prime Minister. Accordingly, Hon'ble
Minister of Railways, Shri Suresh Prabhakar
Prabhu, from the day he became head of this
Ministry, has been relentlessly working on
multiple fronts to speed up growth of Indian
Railways (IR) and improve its financial health.
While on one side Railways' needs to finance
its projects have been met by arranging low
cost funding from Extra Budgetary Resources
(EBR) like financing from Life Insurance
Corporation of India ete, on the other hand,
focused efforts to reduce input costs has been
made. Realizing that about one third of Indian
Railways’ Ordinary Working Expenses goes
towards meeting its energy needs, one of the
important mission set by the Hon'ble Minister
of Railways was to substantially bring down
its energy cost. The first goal under this
mission was to reduce annual electric traction
bill by about 23,000 cr. in next few years.
During 2014-15, total energy cost of Indian
Railways was %31,220cr. This included an
expenditure of %10,436 cr. towards electric
traction (which carries about two thirds of
total freight and about 50% of passenger
traffic), 718,586 cr. towards diesel traction
(which carries balance one third of freight and
about 50% of passenger traffic) and &2,198 cr.
towards supply of electrical energy to various
offices, workshops and railways stations ete,

IR has been procuring electricity as an ordi-
nary consumer for its traction applications
despite being the largest single user of energy
in the country. Accordingly, it has been paying
higher tariffs for energy duly taking the
burden of distribution losses, cross subsidy
and other surcharges of Power Distribution
Companies (DISCOMs). The Electricity Act
2003 conferred Deemed Licensee status on IR
due to its involvement in generation, trans-
mission & distribution of energy from the
time electricity came to India. Accordingly, IR
had been working to get this provision of
Electricity Act operational. However, due to
various factors, it was not happening. Being
the architect of Electricity Act 2003, Shri
Suresh P. Prabhu, Hon'ble Minister of
Railways, took up this task with fresh impetus
and under his stewardship, a strategy was
drawn.
In line with this, Central Electricity Regulatory
Commission (CERC) was requested for is
ug
of necessary guidelines to all State
Transmission Utilities (STUs) and State Load
Dispatch Centers (SLDCs) to facilitate Open
Access to Indian Railways on existing trans-
mission network as Deemed Licensee. This
was made to enable Indian Railways to
procure energy from any generating unit,
including captive generating plants, traders, or
through power exchange up to the intercon-
of railway network in terms of
nection poi
specific provisions of Railway Act
E4 na
In its historic judgment on 5" Nov.'15, CERC
ordered that:
a=
Indian Railways is an authorized entity under
the Railways Act to undertake transmission
and distribution activities in connection with
the working of the railways, independent of
its status under the Electricity Act.
Indian Railways is a deemed Licensee under
third proviso to Section 14 of the Electricity
‘Act and no separate declaration to that effect
is required from the Appropriate Commission.
‘All concerned RLDCs, State Transmission
Utilities and SLDCs are directed to facilitate
long term access and medium term access in
terms of Connectivity Regulations from the
generating stations or other sources to the
facilities and network of Indian Railways.
Finally, IR's vision of drawing electrical energy
as deemed licensee was realized on 26"
Nov.'15 when it started drawing about 200
MW power on Central Railway from Ratnagiri
Gas Power Pvt. Ltd. (RGPPL - A Govt. owned
(gas based power plant)} PSU in Maharashtra,
‘This was for the first time that IR had drawn
energy under open access as a distribution
licensee using state distribution network, IR
contracted about 500 MW from RGPPL for
consumption in the states of Maharashtra,
Gujarat, M.P,, and Jharkhand for meeting its
lectric traction power requirement, The flow
of power in all these four States was com-
pleted by 22" Jan.'16, Further, IR also con-
tracted 50 MW through open tender for taking
on its own transmission network for Dadri to
Kanpur which started flowing from 1“DecI5.
With these actions, average cost of energy for
electric traction in these states has come down
from 27.70 to %4.61/unit thereby giving an
annualized saving of about %1,300 cr.
This is a classic example of co-operation
between Centre and States where they had
worked shoulder to shoulder to implement
provisions of Electricity Act 2003 and improve
efficacy of key public services. While reduction
in input costs will improve resilience of IR, at
the same time, energy released can be used by
States for powering their energy deficit areas
The availability of energy at low price will
enable IR to keep its freight tariff under check
and reduce inflationary impact on prices in
general. In long run, this would increase share
of railways in freight traffic by making. rail
tariff mdre competitive. This would also
reduce pressure on state highways.
With this action, an important Budget
announcement of 2015-'16 to reduce input cost
to IR by %3,000 cr. could be realized. This
document enumerates immediate benefits that
will accrue to Indian Railways by procuring,
energy as a distribution licensee, and its
impact in improving financial performance of
IR. The estimated savings on these accounts
indicates that in next ten years (2015-'25),
these initiatives can generate a cumulative
saving of about %41,000 cr, in electric traction
bill.
In addition to procuring energy at competitive
rates, special emphasis has been laid by
Hon'ble Minister of Railways towards effi
cient utilization of energy. Indian Railways
have been taking various energy efficiency
measures, and as per estimates of Bureau of
iency (BEE), these measures have
reduced energy consumption by more than
3% in electric traction and by about 2.8% in
non-traction applications on year to year basis.
Energy Effi
These initiatives have given a financial saving
of about 400 cr. in financial year 2015-16
alone. This document has a chapter on
Railways’ achievements and its future plans inthis respect as well. It is expected that energy
savings due to induction of latest generation
12000 HP locomotives and electric multiple
units (EMUs) having regeneration capability
can save more than 25% of energy.
IR is committed to contribute towards
improvement of environment. In this direction,
it is focusing on environmental friendly
measures like changing energy mix from fossil
fuel base to renewable energy base which
include use of wind, solar, waste-to-energy
ete. Keeping in line with vision of Hon'ble
Prime Minister, IR has recently installed
26 MW wind plant in Jaisalmer. This has
taken IR's installed capacity of renewable
energy to about 50 MW. Further, IR has
planned to increase its installed capacity of
solar power plants to 1000 MW and of wind
mill plants to about 200 MW by year 2020. In
addition, Indian Railways are working to
develop a long term decarbonization strategy
by sourcing almost 100% of its energy from
renewable sources. This document has a
chapter on action plan towards changing
energy mix for making IR as the first 100%
decarbonized transport system in the world.
With success in reducing electric traction bill
substantially, mission of bringing down
operational cost of Railways has already
staried taking shape. In due course of time,
+
this will also give shape to the dire
Hon'ble Prime Minister that Railways
play a dominant role in meeting tre
needs of the nation in an economical
de-congest highways, create more jobs wil
expansion of rail network and reduce India's
dependence on imported fuel. This humble
beginning with cutting input costs will
strengthen financial resilience of IR, improve
its resource mobilization, and enable shifting
of traffic from road to rail by making it more
attractive. Making these savings happen by
2025 will be a real tribute to Indian Railways
when it will be celebrating its centenary year
of electric traction on Indian Railways.
However, implementation of all these pro-
grams will require modernization of some of
IR's assets to safeguard and insulate its
operations from grid imbalances ete. Further,
Indian Railways have to gear itself for integra-
tion of higher level of renewable energy
through induction of new generation grid
balancing, technologies.
Indian Railways has also embarked upon
mission Electrification with an aim to reduce
dependence on imported fuel & rationalise the
cost of energy for Railways. In light of these
developments, 90% of Railway routes have
been planned for electrification in coming
years.

indian Railways (IR) network is spread
over 66,030 route kilometre (90,803 track
km) connecting 7,137 stations and serving
people of this nation since 1853. Indian
Railways is the fourth largest railway system
in the world. In 2014-'15, Indian Railways
transported 8.22 billion passengers to their
destinations, i. 22.5 million passengers a day,
and 1.1 billion tons of freight across length
and breadth of the country. IR acts as a
vehicle of inclusive growth connecting regions,
‘communities, ports; and centers of industry,
commerce, tourism and pilgrimage across the
country.
Indian Railways .
Indian Railways, along with national highways
and ports, is backbone of India's transport
infrastructure. Currently, about 30% of total
freight traffic (in terms of ton-kilometers) of
the country moves on rail, Further, share of
Indian Railways in certain core infrastructure
sectors such as coal, power, steel, cement and
in other critical sectors like fertilizer is as high
as 70%. The reach and access of its services
are continuously expanding with continuous
improvement through its committed team of
about 1.30 million employees and use of
cutting-edge technologies. The assets of IR as

Electric traction accounting for just 36% of
total fuel expenditure carries about two thirds
of total freight and about half of total
passenger traffic. Due to various initiatives
taken, & procurement of electricity under
open access, electric traction bill for 2015-16
got reduced to 210,200. Further, due to
subdued diesel prices & various initiatives
taken in improving fuel efficiency, diesel
traction bill got reduced to about 316,483 cr.

1n date Indian Railways primarily uses
Oven and diesel for traction
applications. Electric traction which is
spread over about 28,000 route km carries
about 67% of total freight and more than 50%
of total passenger traffic while diesel traction
carries balance 33% of freight and about 50%
of passenger traffic. Indian Railways consume
around 1.8% of total electrical energy
generated in the country and around 3% of
total diesel consumed in the country for its
fraction applications. Being the largest
consumer of energy in the country, Indian
Railways has always been conscious about the
way energy is utilized. It has a long history of
taking actions in reducing its cost of energy
Uvough efficient utilization of energy and
continued up-gradation of technology. Looking
at cost and environmental benefits, lately,
emphasis has shifted from diesel to electric
traction, and in recent past, IR has decided to
speed up this process further to take it to 90%
by 2022.
34 Electric Traction: Journey of
Innovation
Recognizing benefits of electrical multiple units
for suburban areas, electric traction was first
introduced in India on Feb. 03, 1925 in
Mumbai. First Train on electric traction
worked on 1500 V DC System from Bombay
Victoria Terminus to Kurla Harbour. This was
the turning point in development of railways
and also in growth of sub-urban transport
system for Mumbai and for other metropolitan
cities in India. Chennai got electric traction on
May 11, 1931 and became the second metro
city to get the same. India had 388 km of
electrified rail network at the time of inde-

pendence. Keeping in line with international
developments in traction systems, Indian
Railways had decided to adopt 25 kV AC
electric traction system. However, the thrust
on use of electric traction began only in 1961
with introduction of 2900 HP capacity locomo-
tives capable of running at a maximum speed
of 80 kmph, French National Railways (SNCF)
provided initial technical assistance and
consultancy for adoption of 25 kV AC, 50 Hz
single phase electrification system over
Indian Railways.
Today, Indian Railways is not only the largest
institutional consumer of electrical energy but
also unique in a sense that it has extensive
generation, transmission and traction distribu-
tion systems, renewable energy assets, domes-
tic and industrial distribution systems.
3.2 Evolution of Electric Locomotive
Indian Railways took up indigenous produc:
tion of electric locomotives at Chittaranjan
Locomotive Works (CLW) in 1960, and the
first 1500 VDC electric locomotive for Bombay
area, 'Lokmanya’, was flagged off on October
14, 1961. The capacity of electric locomotive
has since then been steadily increasing with
improved technology and development of ine
house production capabilities.
Indian Railways currently has 6000 HP capa
ity 3 phase electric locomotives having 1
generation capability and capacity to ru
passenger trains at 160 kmph and haul freigh
trains with 5,000 ton load. Further, India
Railways have decided to go for doubling thé
power of its freight locomotives from 6000
to 12000 HP which will soon be produced #!miry with latest technology. The growth of
Cmnotive power with time is shown in fig. 3

speed potential of electric locomotive also
steadily increased with time from 80 kmph in
4963 to 160 kmph in 1995. WAP; locomotive
ettified for 160 kmph is hauling the fastest
senger train in India, Gatiman from New
Delhi to Agra. Further, this locomotive has
design capability to run at 200 kmph for
which necessary modifications in its driving

energy. Thus, electric traction can make use of
energy generated from coal, natural gas,
biogas, solar, wind etc. Electrification of
transportation system per se is now seen as a
basic need of modern life. Electrification of rail
transport is now a global priority and a stated
goal of the Government of India also.
Electric traction offers regenerative braking
where kinetic energy of train is converted into
electrical energy thereby resulting in saving of
energy by around 20% in locomotives and
around 30% in electric multiple units. This
saved energy was hitherto wasted as heat
energy in conventional brakes. Further,
regenerative braking does not lead to any
attrition and is also safe and effective.

Indian Railways consumed over 18.25 billion
units of clectrical energy for its traction and
pon-traction applications during 2014-'15 which
¢ about 1.8% of total electrical energy
fated in the country. The total energy bill
jd for consuming this energy was about
2,635 cr. which includes 10,436 cr. for

nergy bill. On traction side, it has been
forking on multi-pronged strategies including
rocuring energy from open market,
introduction of latest energy efficient
locomotives, etc, Similarly, on non-traction

Strategy for Traction Power
Procurement
After success in procurement of power
through open access in 2015-'16, Hon'ble MR
in Budget Speech, 2016 had announced:
In my Budget Speech last year, I had promised
annualized savings of %3,000 crore to be
achieved by third year. It is about 30% of
total traction supply cost. I am happy to
announce that the target will be achieved in
next financial year itself, a year earlier than
envisaged. For the first time, IR has leveraged
provisions of the Electricity Act to procure
power directly at competitive rates, using its
status as Deemed Distribution Licensee. Power
Procurement Contracts already signed and
implemented will mean an annualized saving
of %1,300 crore. Further actions to source
power, already initiated, will deliver
annualized savings of 21,700 crore during
coming year, taking the total to 23,000 crore.
In addition, the saving of %300 crore is being
targeted through demand side management and
energy efficiency measures.
Operationalization of deemed licensee status
has given an unprecedented opportunity to
Indian Railways to address the high cost of
traction energy which is a key variable cost.
Its reduction has wide implications on finan-
cial performance of Railways. After success-
fully availing traction energy through open
access mechanism in Maharashtra, Gujarat,
MP. Jharkhand and U.P. (partly), it has been
established that there is a great potential for
substantial savings through this route.
Accordingly, Indian Railways, through
REMCL, had tied-up about 585 MW from for

74 Key take away
Limited runs of new strategy for procurement
of electrical energy from market as deemed
distribution licensee has shown path towards
substantially bringing down cost of energy for
electric traction in Indian Railways. By
adopting this method of procurement of
power, Indian Railways have broken business
as usual mode and have entered into a new
era in meeting its power requirement. It has
opened various vistas to IR to manage power
requirement in a dynamic fashion taking
benefit of low cost power available through
power exchange, short term contracts etc. This
has brought in factor of innovation in power
procurement in Railways and will change the
way of working in Railways. This innovation
will expose Indian Railways to power sector, a

10.1 Efficient utilization of energy
Indian Railways have been very conscious
about saving energy. It is said that energy
saved is energy generated. From efficient
energy utilization perspective, electric traction
offers a unique feature of regenerative braking
where kinetic energy of a train is converted
into electrical energy can be fed back to
electric grid. This feature has been successfully
incorporated in WAG, WAP, and WAP, class
of locomotives with potential for energy

potential for saving of energy upto 30% In
addition to saving energy, regeneration
increases life of rolling stock wheels and
improves their availability for running traing
thereby making electric traction more
economical
Over last six years, Indian Railways have been
able to improve its Specific Energy Consumption
(GEC) by about 13% through various energy
conservation initiatives, This in effect means a
saving of about %2,600cr.

113 Energy Conservation Measures
Indian Railways have started energy conservation
journey much earlier and at every stage took
benefit of best available technologies including
replacement of T-8 fluorescent tube lights (FTL)
by energy efficient T-5 lights and compact
florescent lamps (CFL), provision of light-
emitting diode (LED) lights, energy efficient
ceiling fans, occupancy sensors, use of star rated
equipment ete. As per assessment made by
Bureau of Energy Efficiency for non-traction
applications, these initiatives have resulted in a
saving of about 2% on year to year basis energy
during last three years despite about 5% increase
in connected load. These efforts have been
regularly recognized at national level and IR has
received several prestigious awards. Till 2016, IR
has bagged 114 energy conservation awards and
in 2016, Indian Railways have bagged 27 National
Energy Conservation Awards instituted by
Bureau of Energy Efficiency, which is the highest
number of National Energy Conservation
Awards received by Indian Railways during last
decade.As a part of energy conservation drive, Indian
Railways have carried out energy audit of 448
"facilities till Mar.'15, and during 2015-'16, energy
audit of 195 facilities has been carried out. For
moving ahead on energy conservation, IR has
signed memorandum of understandings (MOUs)
with Ministry of Power and BEE for co-operation
in improving energy conservation over IR. These
were signed in presence of Shri Suresh Prabhakar
Prabhu, Hon'ble Minister of Railways and Shri
Piyush Goyal, Minister of State, Independent
Charge for Power, Coal and New & Renewable
Energy, underscoring the importance accorded to
energy in national decision making. Additionally,
an MOU was also signed between REMCL and
Energy Efficiency Services Limited (EESL) for
implementation of energy conservation projects
over Indian Railways with an aim to provide a
frame work for promoting future solutions and
facilitate Indian Railways to bring a change in its,
energy mix.
As part of capacity building of staff on energy
efficiency, an international summit on Energy
Efficient Technologies in Railways was held in
New Delhi to share several energy efficient
technologies adopted by various railways across
different countries. Further, to emphasize on
energy management system in Zonal Railways,
Contre for Railway Information Systems (CRIS) has
developed Indian Railways Green Energy
(IRGREENRI) portal to disseminate green
initiatives adopted over Indian Railways.
Ministry of Railways has issued directives to
Zonal Railways to utilize LED tube light fittings
under Domestic Efficient Lighting Programme

projected to approximately double by 2050°,
Accordingly, for reduction in GHGs, transport
sector needs to adopt environment friendly
technologies.
It is a settled fact that decarbonization of
electrical energy demand is comparatively
straight forward than decarbonizing non-
electrical energy demand. This is due to
electrical energy being neutral to primary
energy source. Electrical energy demand can
be decarbonized using clean power sources
such as solar, wind, hydro, and waste-to-
energy. Further, decarbonized electricity is a
key thrust area of government with renewable
energy on top of Hon'ble Prime Minister's
agenda.
While two-thirds of freight and more than
half of passenger traffic of IR move on
electric traction, road transport is continuing
its dependence on imported liquid fuels
Hence, there is a major scope for switching
transport towards Rail from the road sector
and to reduce GHG emissions. This would
improve the quality of urban environment in a
big way.

tensive, provisions of the
Electricity Act 2003 has given
possibilities for decarbonizing energy basket.
Indian Railways have already taken initiatives
towards decarbonizing its energy envelop.
These include installation of 36.5 MW of wind
generation and 14 MW of solar power plants
which are in operation and supply power to
Indian Railways. In addition, 50 MW of solar
rooftop power plants are under different
stages of commissioning. Indian Railways is
working towards taking installed capacity of
solar plants to 1000 MW by 2020.
By their very nature, railway stations,
maintenance facilities and office buildings have
sufficient untapped space to implement solar
generation. The released passenger coach
batteries also offer storage solutions for
smaller locations to avoid use of Diesel
Generating (DG) sets.
13.4 Solar Energy
As part of Indian Railways Solar mission to
reduce dependence on fossil fuels and keeping
in line with Budget 2015-'16 announcement of
Hon'ble MR, Indian Railways has plans to set
up 1000 MW solar power plant in next five
years. As part of this, IR will setup solar
power plant on rooftops of railway stations,
buildings and on railway land as per
following:

Indian Railways has started installing solar
power plants in 2014-'15 on administrative
buildings, stations and hospitals. Harnessing of
solar energy was enhanced in following, years
taking total capacity to about 10 MW by 2015-
"16. This includes one megawatt solar power
plant on rooftop of Katra Railway station.
Further to it, order for 6.5 MW solar plants
(Five locations each of 500 kWp, 20 locations
each of 100 kWp, 200 locations each of
10 kWp) was issued. These plants have started
getting commissioned and this will take total
installed capacity of solar power plants to
17 MWp. Under the net metering provision,
this power can be consumed in railway grid
thereby paving way for steady decarbonization’
of Indian Railways. The pictures of sol
power plants set up by various Zonal
Railways are as under:

To harness solar energy on a large scale, Zonal
Railways have been allocated installation of 50
MW capacity under phase for which open
tenuers have been issued. These plants will
stari getting installed from July'17 onwards.
Further, Zonal Railways have identified
additional capacity for installing 100 MW solar
power on rooftops. REMCL has invited
tenciers for the same. For all these rooftop
insiallations, Viability Gap Fund (VGE) from
Ministry of New Renewable Energy (MNRE)
has been obtained. Further tenders for rooftop
insiallations will be floated in a phased
manner for 350 MW under the MNRE's
incentive scheme for which consultancy has
been awarded to M/s. Central Electronics
Limited (CEL) for assessing capacity. The total
installed capacity of rooftop solar power plants
on railway buildings is projected at 500 MW
by 2018-'19.
Following actions have been taken for
installation of 500 MW solar plants on land
systems:
50 MW is being set up through
Reva Ultra Mega Solar Limited
(RUMS) in MP.
40 MW will be setup through
Solar Energy Corporation India
(SECI) for traction load with
battery backup (30 minutes) as
per MNRE special scheme.
150 MW Solar power plant will be
setup through SECI for meeting
non traction power requirement.
For balance about 250 MW,
REMCL is working out various
options.

Indian Railways have targeted to increase its
installed capacity of wind power to about 200
MW. Of this, 10.5 MW capacity wind mill
plant was set up in Tirunelveli district in
Tamil Nadu for meeting energy requirements
of Integral Coach Factory (ICF), Chennai
which has generated 138.4 million units till
Mar.'16. Further, 26 MW windmill power
plant was commissioned in Oct.'15 in
Jaisalmer, Rajasthan which has generated more
than 60 lac units. Further to it, installation of
balance capacity is planned through tariff
based bidding and partly through investment
by Railways through REMCL.
These capacities will be created based on
requirement of non-solar Renewable Purchase
Obligation (RPO) obligation in various states.
IR is planning to install 56MW wind mill
through tariff based bidding for meeting non-
traction loads in Maharashtra, Andhra Pradesh,
Tamil Nadu and Madhya Pradesh. Further,
REMCL shall set up 100 MW capacity wind
mill plants

Renewable Energy opportunities
Railways are committed and poised to
induct about 1.2 GW of renewable
energy. Globally, it has been accepted that
renewable energy generation creates
quality and sustainable employment.
Creation of Indian Railway Transmission
Line Network: This would serve to give
resilience to IR's traction network and
reduce its dependence on STUs.
Instead of just aiming at saving of costs
by a mercantile approach, the complete
technical architecture would be designed
under leadership and guidance of in-
house resources. Indian enterprises would
engineer products and deliver complete
structure,
By association with academic institutes,
young minds would be exposed to best
engineering practices, engineering eco-
nomics, and energy systems, and give
sufficient practical challenges to R&D labs
to take mantle of global leadership in
power systems.
As Rail Energy Management System gets
more integrated, possibilities of further
optimization would grow. Thus, by highly
selective system up gradation, network
level energy flows can be better visual-
ized, monitored and hence controlled.jo improve financial performance of
Indian Railways, reversing the
increasing trend in fuel expenditure is
an important area as it constituted around
27% of its ordinary working expenses. In this
regard, operationalizing the deemed licensee
status available to Indian Railways was the
first land mark achievement towards reducing
the energy bill of electric traction. In 2015-'16,
these initiatives have resulted in an
annualized savings of %1,300 cr., and it is
expected that these actions would take
annualized savings of about 3,000 cr. In few
years.
‘The impact of procuring power as a Licensee
will bring in savings of more than %4,000

Railways’ finances over next ten years will
be more than 741,000 cr. and will add to
making Indian Railways a more customer
friendly mode of transport. As a snowball
effect, diesel procurement system is also being
revamped by procuring crude oil directly
which has the potential for saving of about

India currently stands at a moment of
opportunity in which it is evident that
transition to a low-carbon system can bring
about economic growth. The falling costs of
renewable energy, ambitious government plans
for rapid deployment of renewable energy,
and increasing financial support from
international agencies, governments and
investors indicate that transition to a low-
carbon economy is not only possible but also
already underway. Since Indian Railways is
the single largest consumer of electricity in
India by consuming about 18 TWh/year,
prioril g decarbonisation of Indian
Railways could help India achieve its 2030
emission reduction goals as well as improve
energy security by reducing fossil fuel imports.
Targeting 100% decarbonisation of IR is a
strategic example for transportation sector as
well as to Indian industry as a whole. As part
of this strategy, IR has planned to set up 1000
MW solar power plants and about 200 MW of
