From the Presidents Desk
Dear Friends,
Exploring the power potential in the North-Eastern Region of
India has always been a challenging affair. If the resources
available are properly developed, the region will not only be able
to export power, but, over time, will also end up attracting
investments in the kind of manufacturing in which uninterrupted
electricity supply is essential. The estimated hydropower
generation potential of the Northeast is huge, but capacity
development is woefully short of the potential. The Total
hydro-power potential in the region including Sikkim is 63,257MW,
while presently; only 3% of the assessed potential has been
developed in N.E. Region. This issue of IEEMA Journal takes a deep
dive into the N.E. Region
power and development agenda. In consonance, coming April IEEMA
is privileged to organise the 5th Eastern Region Summit - Konnect
North East & Beyond at Guwahati, where we will focus on
Capacity Building for Power Sector in NE India in terms of the
seminar, besides an interactive exhibition spread over 20,000 sq.
ft.
In the same month, the Metering India seminar will be hosted by
IEEMA at New Delhi which will focus upon - last mile connectivity
and consumer participation and initiatives like Demand Side
Management, Renewable Energy Integration, ToD Tariff
implementation, Consumer home energy management and Revenue
protection for the utility. The seminar is envisaged to strengthen
the technological choices and offer the options to empower and
utilize existing infrastructure for a result oriented future. In
partnership with all stake holders, let us add a Smart Indian
Dimension to our future and endeavour to lead the global trend!
With immense contentment I hereby announce the dates for the
next ELECRAMA to be held in Bangalore from February 13 to 17, 2016.
Going ahead from just discussing Transmission and Distribution,
ELECRAMA-2016 will focus on much broader agendas conforming to core
infrastructure sectors of oil & gas, cement, renewables,
nuclear to SMEs. You will be hearing more from the ELECRAMA-2016
Organising Committee Chairman on this.
All our activities, re-assures us that the IEEMA brand lives and
sustains its promise Your link to Electricity.
Best wishes.

Dear Members,
Let me take this opportunity to express my best wishes to
everyone on the Founders Day of IEEMA on 25th February.
Sitting in the Mumbai office on the Sixty Eighth Foundation day,
I reminisce the past while looking at a challenging future. Sixty
eight years have witnessed IEEMA building itself block by block and
many of you have been a part of the growth story.
Last year saw a number of new initiatives bear fruit. IEEMA
reached out to its members one-on-one . Interaction with key
Utilities have been undertaken. Intelect saw its birth. Engagement
with the Government has increased considerably. The need now is to
ensure that the efforts are sustained and incrementally shored up.
Continued support and guidance from everyone has helped the
Association steer through challenges with elan and achieve new
heights.
It is now time to set our sights higher and channelise combined
and synchronous efforts towards achieving new targets. Some of the
thrust areas would be as follows:
a) Further strengthening IEEMA brand.
b) Evolve Elecrama-2016 witn enhanced international colour
making it a true Global event.
c) Redefining value creation for IEEMA members.
d) Renewed thrust on joint ventures and strategic partnerships
to be able to provide a launch pad for our members
India is truly at the cusp of change. The positive atmosphere is
suitable for pursuing our members interests. Support from our
elected representatives during continued interactions is an
indication that we are treading the correct path. IEEMAs four point
agenda submitted to the Government of India, that was mentioned in
the last edition is being actively pursued and we expect to see a
couple of welcome policy changes in tender procedures, vendor
development and pricing. Our Association is committed to furthering
member interests and make IEEMA a valuable partner in progress.
Looking forward to a challenging year ahead.

Dear Friends,
Today across geographies, Electricity and communication remains
the common denominator for growth and development. Traditional
means of establishing connectivity and providing sustainable energy
remains a challenge, which is being met by a multi model approach
thereby rapidly changing the dynamics.
The world is moving leaps and bounds in leveraging technology in
all facets of electricity. Interestingly, India happens to be in
the epicenter of this threshold change, given her phenomenal
electricity infrastructure ramp up through traditional generation,
transmission as well as alternate modes using renewables linked to
micro & nano grids.
All topics relevant to global electricity have found resonance
in the Indian context, right from UHV 1200kV to rural micro grids
to intelligent electricity. India is truly the microcosmic
representative of the diversity of challenges and solutions that
exists in the global electricity sector. By the way, India today is
the worlds third largest producer of electricity, a reminder of the
growing clout of India in the global power equation.
ELECRAMA through the years has evolved along the contours of the
sectoral landscape to reflect these dynamic changes in the
ecosystem and today is poised to take a leadership position of a
truly global platform for technology, product and knowledge
MESSAGE Aaditya R Dhoot Chairman - Organising Committee
ELECRAMA-2016
sharing amongst all key stakeholders of the electricity
ecosystem earning itself the status of a WORLD ELECTRICITY
FORUM
The coming edition will witness the tectonic shift to that of a
truly global platform where the global leaders, movers and makers
of the power fraternity will come together to find answers to the
rapidly evolving scenario in that of sustainable electricity
transmission, distribution, consumption and conservation.
Operationally, the shift would be towards keeping an agile,
technology led approach, starting with an online space booking
system, exhibitor and visitor engagement portal. In addition, the
experience quotient will definitely be accentuated and a host of
business opportunities are in the offing. More global participation
is guaranteed in all aspects of ELECRAMA.
Please feel free to contact me with your inputs and suggestions,
which we assure, would be considered while working towards this
global phenomenon.
A superlative event experience for all stakeholders is
definitely on the cards!
Afterall, its ELECRAMA time, where power meets power!
Best regards,
(Aaditya R Dhoot)

Continuing with Prime Minister Narendra Modis focus on
development of north-eastern region, as he said, We want
development through energy sector and northeast Indias unemployment
problems would be solved through this sector. Japan and Germany
have also promised to help northeast India in various means.
The government has already identified 21 such key projects worth
over ` 1 lakh crore for ensuring faster clearances to them. Out of
these 21 projects at least 11 are power projects including 3097 MW
Etalin Hydro Electric Project on Dri River and Tangon River in
Dibang Valley in Arunachal Pradesh worth over ` 24,200 crores, 1800
MW Kamala Hydro Electric Project worth ` 20,141 crores and 2000 MW
Hydro project on Subansiri River in Assam worth ` 11000 crore are
some of the big projects for NE.
The power sector provides immense potential for the northeastern
region. If the resources available are properly developed, the
region will not only be able to export power, but, over time, will
also end up attracting investments in the kind of manufacturing in
which uninterrupted electricity supply is essential. The estimated
hydropower generation potential of the Northeast is huge, but
capacity development is woefully short of potential.
With the initiation of the North East Industrial and Investment
Promotion Policy, the Central government practically made the
entire Northeast a special economic zone in 2007, providing major
incentives to investors, including 100 per cent tax exemptions and
duty cuts, capital subsidies of up to 30 per cent and even
insurance reimbursements. Private
investment has so far been elusive, mainly due to the lack of
quality infrastructure.
Meghalaya Energy Corporation LtdTo get a better view of the
situation IEEMA Journal spoke to Mr K N WAR, DIRECTOR (HRD),
Meghalaya Energy Corporation Ltd. Mr K N WAR spoke about the
prospects of Hydro power in Meghalaya, he says, The hydro power
potential of the State of Meghalaya is 3000 MW which is about 3% of
the total hydro potential of the country. Presently, the installed
capacity 314.70 MW and about 64.0 MW capacity is under
construction.
Sharing a comprehensive scheme for strengthening of Transmission
& Distribution he says, The North East Region Power System
Improvement Project (NERPSIP) is a comprehensive scheme to be
funded by World Bank and Government of India. The scheme comprises
of development of Transmission, Sub-Transmission/ Distribution
system up to 33 kV. The work covered under Tranche I, for Meghalaya
Power Transmission Corporation Limited (MePTCL), are broadly
highlighted in the following table.

Speaking about the status of Reforms he says, The Power Supply
Industry in Meghalaya had been under the control of the erstwhile
Meghalaya State Electricity Board (MeSEB) from 21st January 1975.
The Government of Meghalaya unbundled and restructured MeSEB with
effect from 31st March 2010. The Generation, Transmission and
Distribution businesses of the erstwhile Meghalaya State
Electricity Board were transferred to four successor companies. The
State Government issued a Notification The Meghalaya Power Sector
Reforms Transfer Scheme 2010 thereby giving effect to the transfer
of assets, properties, rights, liabilities, obligations,
proceedings and personnel of the erstwhile MeSEB.
On 31st March 2012, Government of Meghalaya issued further
amendment to the above mentioned transfer scheme, to transfer
Assets and Liabilities including all rights, obligations and
contingencies with effect from 1st April, 2012 to namely:
u Generation: Meghalaya Power Generation Corporation Ltd.
(MePGCL)
u Transmission: Meghalaya Power Transmission Corporation Ltd.

The Total hydro-power potential in the NER including Sikkim is
63,257 MW. While presently, only 3% of the assessed potential has
been developed in N.E. Region. There are 143 HE projects with
capacity of 57,167 MW identified by CEA/States in NER for
implementation and monitoring. Out of these, 79 projects have been
allotted in Arunachal Pradesh as on date: 75 projects allotted to
private sector with capacity of 29512 MW and four projects for a

Strengthening of the Intra-State Transmission and Distribution
System The Union Cabinet chaired by the Prime Minister, Shri
Narendra Modi gave its approval for the North Eastern Region Power
System Improvement Project (NERPSlP) for six States (Assam,
Manipur, Megha laya , M izoram, Tripura and Nagaland) for
strengthening of the Intra State Transmission and Distribution
System at an estimated cost of ` 5111.33 crore including capacity
building expenditure of ` 89 crore. The scheme is to be taken up
under a new Central Sector Plan Scheme of Ministry of Power (MoP).
The scheme is to be implemented with the
assistance of World Bank loan and the budget of MoP. Presently,
all the six NER States are connected to transmission network at 132
KV and below. The 33 KV system is the backbone of power
distribution system in the six NER States. In order to reduce the
gap between the requirement and availability of the
intra-state transmission and distribution system, it is
necessary to provide 132 KV / 220 KV connectivity to all the six
NER States for proper voltage management and lower distribution
losses. Similarly, the distribution system in all
six NER States which mainly relies on 33 KV network would be
strengthened substantially.
The Total hydro-power potential in the NER including Sikkim is
63,257 MW. While presently, only 3% of the assessed potential has
been developed in N.E. Region. There are 143 HE projects with
capacity of 57,167 MW identified by CEA/States in NER for
implementation and monitoring.
North Eastern Regional Power CommitteeMr B Lyngkhoi, Director,
North Eastern Regional Power Committee, Speaks to IEEMA Journal and
gives an overview of the power sector of North East.
North-East is called as the Power House of India: Can you please
share the prospects and problems and also overview of the power
sector of North East.North East is termed as future power house of
India. According to an estimate of the Central Electricity
Authority (CEA) and private power developers, Arunachal Pradesh has
the potential to generate over 57,000 MW of hydro power. More than
150 memorandums of understanding (MoU) for Mega dams have been
signed in Arunachal Pradesh State alone. Some of the ongoing
projects in AR. Pradesh are 2000 MW Lower Subansiri of NHPC, 600 MW
Kameng HEP of NEEPCO, 104 MW Pare of HEP which are expected to be
completed by 2016-17. The proposed 3000 Dibang HEP project, 1750 MW
Lower Demwe HEP and many more will be coming up in future in AR.
Pradesh.
The Manipur Government singed MoUs with NEEPCO to undertake 60
MW Irang HEP project at Irang ricer, 190 MW Pabram HEP over Barak
River, 67 MW Chakha HEP at Barak River, Tuivai HEP over Tuivai
River in Manipur. Policies, such as Manipur Hydro Power Policy,
2012 are also formed to promote mega dams across the North East
region.
Apart from above, 726 MW of OTPC (ONGC Tripura Power
Corporation) will be fully generated by February, 2015, then 750 MW
of NTPC at Bongaigoan (One unit of 250 MW) is likely to be
synchronized by March, 2015, 60 MW Tuirial HEP in Mizoram of NEEPCO
etc. Apart from these many more projects are in the pipeline in
NER.
Looking at these projects, it is clearly seen that NER will be
the future power house of India. However, since NER is highly
seismic zone of Category V, careful planning has to be carried out
while constructing such big dams to avoid flash floods in
downstream as well as environmental issues. Due to up-coming hydel
projects- several thousand hectares of agriculture land will be
submerged and this will aggravate climate crisis. This is a matter
of great concern.
What are the plans to evacuate the power surplus of NER? Please
give the details of comprehensive scheme for strengthening of
transmission and distribution system in north eastern region? What
are the Reforms & Restructuring Reforms in Power Sector?
North Eastern Region Power System Improvement Project (NERPSIP)
for six (6) States (Assam, Manipur, Meghalaya, Mizoram, Tripura and
Nagaland) for strengthening of the Intra-State Transmission and
Distribution System.
The development of Transmission and Distribution (T&D)
systems in the North Eastern Region (NER) has lagged behind both in
terms of Inter-State and Intra-State connectivity. Taking this into
consideration, the entire transmission system development in NER
was discussed in detail in First Sectoral summit

of North Eastern Council at Pasighat in Arunachal Pradesh in
January, 2007 and accordingly, Pasighat Proclamation on Power was
declared. Pursuant to this Proclamation, a Comprehensive Scheme was
prepared for strengthening of Transmission, Sub-transmission and
Distribution system of the North Eastern Region by Central
Electricity Authority (CEA) in consultation with Power Grid
Corporation of India Limited (PGCIL) and all the States of North
Eastern Region (NER).
Based on the above Comprehensive Scheme, Detailed Project
Reports (DPRs) comprising Transmission, Sub-transmission and
Distribution systems upto 33 kV were prepared by PGCIL in Jan, 2010
for each of the six (6) North Eastern Region States namely, Assam,
Manipur, Meghalaya, Mizoram, Tripura and Nagaland. Subsequently,
Department of Economic Affairs had approached the World Bank in
November, 2010 to provide US $ 1500 million of International Bank
for Reconstruction and Development (IBRD) funding support to the
scheme, in three tranches of US$ 500 million each.
Ministry of Power appointed PGCIL as Designcum-Implementation
Supervision Consultant on 1st February, 2012 and asked PGCIL to
approach the World Bank and commence project preparation. In order
to structure the various elements of Transmission and Distribution
schemes under first tranche discussions were held among the World
Bank, CEA, States and PGCIL over extended period.
The elements were prioritized in such a manner that they could
be implemented expeditiously due to relatively less constraints of
Land Acquisition, Resettlement and Rehabilitation (R&R) and
Forest clearance issues. Accordingly State-specific DPRs for
Transmission/Sub-transmission and Distribution systems (33 kV and
above) of six NER States were updated by PGCIL in January, 2014,
keeping in view the latest requirements based on the ground
situation in the States. As regards the overlying Inter State
Transmission System (under Central
Sector jurisdiction), it may be mentioned that the existing
system along with the transmission system under implementation for
generation projects namely Pallatana, Bongaigaon, lower Subansiri,
Kameng and the NER Strengthening Schemes II & III shall be
adequate enough to feed into the Transmission & Distribution
system covered under this proposal.

Looking at these projects, it is clearly seen that NER will be
the future power house of India. However, since NER is highly
seismic zone of Category V, careful planning has to be carried out
while constructing such big dams to avoid flash floods in
downstream as well as environmental issues.

cost as a Project Management Consultant (PMC). The consultancy
fee shall not be charged on the cost of land and Rehabilitation
& Resettlement (R&R) as recently done for balance two NE
States under similar scheme for Arunachal Pradesh & Sikkim, for
which investment approval was recently accorded by Cabinet
Committee on Economic Affairs (CCEA) on 15.09.2014. The projects
will be owned by the State Utilities, which would undertake
Operation & Maintenance (O&M) upon progress ive
commissioning of the projects at their own cost.
In-principle approval to the project proposal was accorded by
the Planning Commission in September, 2011. The project is being
taken up as Central Sector Project with 50% funding from GoI &
balance 50% from The World Bank under IBRD.
An amount of ` 200 Crore has already been provided in Budget
Estimate (BE) 2014-15. Savings accrued during XII Plan under the
overall budget of Ministry of Power (MoP) would be used for funding
this proposal, which has the support of Planning Commission. Fund
requirement under XIII Plan shall also be appropriately provided
for.
It has been envisaged that during the implementation of this
proposal, the capacity of the State Utilities shall be enhanced to
enable them to contribute significantly more during subsequent
tranches, preparation for which shall be commenced after approval
of the first tranche of the loan. To facilitate capacity building,
it has been proposed that expenditure to an extent of ` 89 Crore
shall be fully borne by Government of India (GoI). This shall be in
addition to 50% share of GoI in funding.
The cost estimate of the project has been worked out as `
5111.33 Crore at February, 2014 price level as summarised
below:
The completion cost of the project has been worked out as `
6092.10 Crore (including consultancy fee & service tax thereon)
as per guidelines dated 6.8.1997 issued by Ministry of Finance
considering the average increase of Wholesale Price Index
(WPI) (80% weightage) and Consumer Price Index (CPI) (20%
weightage) for the preceding 12 months period.
The project is considered as a Central Sector project with 50%
contribution from Government of India (through the budget of
Ministry of Power) and 50% contribution
as loan from the World Bank which amount to ` 5022.33 crore plus
` 89 crore for capacity build ing expenditure to be funded by
Government of India through the budget of Ministry of Power as
mentioned in para above. The financing of the World Bank funding
(50% contribution) would be as per the extant guidelines for the
North Eastern Region i.e., 90% grant and 10% loan to be borne by
the States. The States would also bear the foreign exchange rate
variation corresponding to 10% of the World Bank loan.

What are the key issues concerning the power sector in the
region?
Since the power generation in the region is hydro-thermal mix,
the region will be power surplus soon in both hydro and lean hydro
season. But the main concern is that power connectivity for all by
2020 as plan by Govt. of India.
The present power demand of the seven NE States is of the order
of 2200 MW. As per 18th EPS (Electric Power Survey) report of CEA,
the projected power demand of the region will be 2966 MW by 2016-17
and 4056 MW by 2021-22. Due to vast geographical spread of the
States, the power demand is scattered over large distances.
Therefore, it becomes necessary to provide 132kV connectivity to
the distant locations so that power supply from regional grid may
be extended to all over the State.
The proposal is a major step towards meeting the national
objectives like power to all, especially in the backward North
Eastern (NE) region for inclusive growth, through enhancement in
access of consumers to Grid connected power supply, besides
improving its availability, adequacy, reliability and
affordability. This shall also increase per capita power
consumption in these States, which presently varies from 240.3 Kwh
(Assam) to 690 Kwh (Meghalaya) compared to the National average of
914 Kwh. The transmission portion of the proposal has been planned
for absorption of power from the overlying regional grid and to
feed it to different parts of the State. The Distribution portion
has been planned to facilitate dispersal of this power to the final
consumers.

Our country is heavily dependent on fossil fuels. More than 65%
of power generation in the country is coal based. The coal, right
from its mining to usage is extremely polluting the environment and
is largely responsible for global warming. Otherwise also if the
exploitation of the fossil fuels is continued at the present pace,
the resources have be exhausted in decades time whereas energy
security is key to the economic growth and welfare of any country,
state. Therefore worldwide there is a trend to protect the globe
against the ill - effects of excess exploitation of the fossil
fuels and the countries are stepping fast towards non conventional,
renewal energy resources like solar, wind, biomass, geothermal etc.
World over research and technological developments are taking place
to harness energy from the renewable resources and their economic
viability is increasing
For any change, both motivation and mandate are equally
important. So the central and state governments have been
incentivizing, facilitating the investors/developers for
establishing renewable energy plants and the regulators have
prescribed for the power distribution entities purchase of renewal
energy, at least a certain percentage of their total consumption,
called Renewal Purchase Obligation. As of now it is an obligation
for the Discoms as the purchase of renewal power is costing dearer
than the conventional power. For example, the Rajasthan Electricity
Regulatory Commission has prescribed the
following Regulatory Purchase Obligation ( RPO ) for the state
Discoms :
Year Obligation expressed as percentage of energy consumption (
% )
Wind Biomass Solar Total
2104 15 6.80 0.70 1.50 9.00
2015 16 7.30 0.90 2.00 10.20
2016 - 17 7.80 1.10 2.50 11.40
By the year 2022, the above total percentage of renewal purchase
obligation is expected to exceed 20%.
Hardly any state could so far fully achieve the target of
renewal purchase obligation, perhaps. Even the state of Rajasthan
which is leading in generation of renewal energy would not be able
to fully achieve the RPO target for the year 2014 15. Rajasthans
expected total energy consumption for the year 2014 15 is 62000
Million units and the maximum demand around 11000 MW. With the
environment changing to business friendly and the country heading
towards "Make In India", the power consumption across the states
will increase at faster pace and so the regulatory purchase
obligation to ensure appropriate energy mix. Rajasthan is blessed

and solar energy but due to uncertain, less reliable
availability of the wind power, its effective cost to Discoms is
higher compared to solar. So may be the case with other states
also. The average annual and daily availability of sun in the state
is 300 days and 12 hours respectively. The average generation per
day per KW solar capacity is 5 6 units. Therefore higher increment
to solar purchase obligation compared to wind shall be more
economically advantageous to Discoms.
In the above backdrop and to harness the benefit of the maximum
available solar intensity in the interest of the state, the state
government has issued Rajasthan Solar Energy Policy - 2014. Under
the policy the state government will encourage and facilitate
investors and developers for establishing an aggregate capacity of
25000 MW solar power during the ensuing years. The solar power has
an upper edge due to its characteristics like wholly pollution -
free, easy decentralized generation.
There is a fundamental principle that a product will have
maximum value (ratio of utility and price) if its raw material, all
facilities for production and demand is at the same place. Such
principle is more applicable to electricity as its transportation
from the generating station to the end consumer suffers from
inevitable T&D Loss besides the cost of transportation. More
over the generation and consumption are simultaneous. Therefore it
would lead to a most advantageous situation if the generation of
electricity is technically and economically viable at the consumers
premises itself and the roof top solar plant is the right answer.
This can be conveniently installed on the consumers roof top or on
the vacant space available at the consumers premises. It may be off
grid or grid connected.
The roof top solar plants offer the following advantages
compared to the distantly located generating plants :
1. Minimum expenditure (almost zero) on transmission and
distribution infrastructure for that capacity.
2. Negligible transmission and distribution loss. In reference
to the state of Rajasthan 140 units generated by a distantly
located power station is approximately equivalent to 100 units
generated by the roof top plant.
3. Installation as also the maintenance of roof top solar plants
are labourintensive jobs and so would generate local
employment.
4. Since solar power is available during higher demand hours of
the day, it would optimize Discoms power purchase cost.
The state Discoms are approaching regulators for determination
of tariff and regulations for grid connectivity of roof top solar
power.
Jaipur Discom has also filed a petition before the state
regulator for determination of tariff and grid connectivity
regulations for One KW to One MW solar roof top plants.
Germany, the world leader in solar power having installed a
capacity of around 28000 MW solar power is almost roof top. Every
fifth house in Australia has a roof top solar plant with aggregate
capacity of approximately 4000 MW. But India so far is reported to
have a total roof top solar capacity approximately 285 MW only,
although the worlds largest roof top solar plant of 7.2 MW capacity
has been recently commissioned in countrys Punjab state. It is
supplying power to Punjab state utility. As per an industrial
survey, India has potential to install 41000 MW roof top solar
power at commercial and industrial premises and approximately 35000
MW at residential premises by the year 2024. Roof top Solar Photo
Voltaic Plants ( SPV ) of total capacity 2.5 MW have already been
commissioned on more than 100 roof tops of Gandhi Nagar City of
Gujarat and the state has declared installation of another 25 MW
roof top solar plants for its Vadodara, Mehasana, Bhavnagar, Rajkot
and Surat cities. Solar Energy Corporation of India (SECI ) has
awarded a work contract for installing total capacity of 5.5 MW SPV
plants on the roofs of Bengaluru, Delhi, Chennai and Gurgaon. All
these plants are based on rent - a - roof model. The ministry of
urban development has also launched a mission to install SPV roof
top solar panels of aggregate capacity 100 MW over 629 central
government buildings in 18 different states of the country through
SECI. The state

of Haryana has made installation of roof top solar plants
compulsory for a specific category, larger size residential,
commercial and industrial premises with effect from September 01,
2015.
The roof top plant is beneficial to the premises holder consumer
also. The premises owner may get rent from or share profit with the
plant developer, may get power in the event of grid failure and a
sense of satisfaction for contribution to environment protection.
The roof top SPV are safe and do not cause any inconvenience to the
premises holder. The investors/developers may be selected through a
proper process by the states nodal agency or the Discoms. The
tariff for roof top solar plants may be determined through
competitive bidding or the plants may be installed under Renewal
Energy Certificate(REC) mechanism. The power so generated may be
purchased by Discoms. The Central Electricity Regulatory Commission
has recently revised the floor price of solar REC to ` 3.5 per unit
and the central government
Author
Arjun Singh Former Managing Director Jaipur Discom
has proposed amendment to the electricity act 2003, making
stringent provisions for non-compliance to RPO. The amendment also
proposes several incentives for renewal energy generation. As a
result of continuous research in India and abroad, use of advance
technology and available incentives, the capital cost of solar
plants is
decreasing every year where as cost of supply to consumers by
Discoms is on the increasing trend. It is expected that by end of
the another two years, cost of roof top solar power will be less
than the cost of supply from the utilities. As on date the roof top
solar is the most economical source for Discoms to comply with the
Renewal Purchase Obligation. Looking to all such advantages we may
call it energy for the future.

Overview of upcoming projects At present we are one of the
leading manufacturers and pioneers in crimping technology (cable
lugs and crimping tools) both in the local as well as export
market. However we would like to broaden our cable accessories
range to include brass parts like cable glands, machined
components, switch gear parts made from copper, and finally snap-on
terminals for the automobile sector.
Priority areas We are focusing on the US market and of course
the local market. The US economy is on a rebound and we feel the
time is right to aggressively market our products there. We have
already obtained UL certification for hundreds of products that are
typical to that market.The Indian market is on the cusp of
exponential growth and we would not want to miss the next wave of
growth which should begin very soon. We are expanding our marketing
effort and also our sales force and dealer network.
Projects in pipelineApart from the aforementioned projects, we
are giving impetus to Bimetallic Lugs and Connectors. We are glad
that the Solar and Windmill industry is adopting this component, as
it is technically superior to conventional lugs. For the export
market we have developed and are expanding our Split Bolt range,
which is a product that finds application in grounding.
Expansion plans Seeing such a good demand in bimetallic lugs,
and judging by the number of power/renewable energy projects in the
pipeline, we are contemplating to buy
another Friction Welding machine. In the second half of the year
we plan to add 20 Power presses of various tonnages. We have
already bought CNC lathe and milling machine to manufacture tailor
made machined parts. Thus expanding upon our existing CNC
machinery. Although we are optimistic about the growth in the
economy, a certain amount of caution is due and we would be
expanding in an organic manner. We already have a number of our
processes automated and we are currently looking into innovative
automation solutions and trying to adopt best practices into our
manufacturing systems.
Challenges On the sales front the challenge we face is
competition from the unorganized sector supplying cheap low quality
lugs and terminals. We are trying to solve this issue by educating
our customer about the dangers of using low quality copper lugs,
however the market is majorly governed by price thus quality
sometimes takes a backseat. On the manufacturing front the
recurring problem faced every year is labour shortage and even when
labor is available the quality and skill is much left to be
desired. The government needs to improve the education
infrastructure and we need ITI and engineering institutes to churn
out quality technicians and engineers. In fact I feel this is one
of the major areas where China has overtaken us. The labour rates
there may be higher but the productivity of the workforce offsets
the higher wage.
Five years planWe are targeting growth in revenues to the tune
of 25% year on year for the next five years. Our strategy is in
place and we need to focus on implementing the same on a consistent
basis. Currently we are a major exporter as 80% of our sales is
from the export market. We have 15-20% share in the local market
and we would like to increase that to at least 50% in the coming
years.
We face competition from the unorganized sector supplying cheap
low quality lugs and terminals: ED, BEWL

The Current Transformers (CTs) are Instrument Transformers and
are very vital equipments used on the HV, EHV and UHV level
systems. These transform the Primary current (which is directly not
measurable as being of HV/EHV levels) into Secondary current which
is almost the replica of the primary current and can be easily used
in the secondary instruments/equipments like protective relays,
control panels, energy meters and for SCADA applications etc.
Therefore the CTs are used as input devices producing secondary
currents proportional to the primary currents within the required
accuracy limits.
Theory /Principle of Current Transformers
The Current Transformer follows the principle of maintaining
balance between Primary Ampere-Turns and Secondary Ampere-Turns.
Thus the following Ampere-Turn equation holds good.
Ip x N p= Is x Ns,
Where; Ip= Primary current,
Np=Primary No. of turns.
Is=Secondary current.
Ns= Secondary No. of turns.
Kn= Ns/ N p, turn ratio or Transformation ratio.
Im=core magnetizing component.
Ie=Iron loss component, Io=Exciting current. =the phase angle of
the Current Transformer. Note:
Np (No of primary Turns can be 1, ie it is a bar primary
CT).
Following figures depict the basic connection of CTs:

P1-P2 =Primary terminals,Ip =Primary Current, S1-S2= Secondary
terminals., Is=Secondary Current, Im=Core Magnetizing Current,
RCT= Internal winding resistance of the CT,RB=Resistance of the
connected Burden.
ZT= RCT + RB.
Note:In the above figure the Primary Turns have been
shown,However in some CTs there is bar primary ie the CT has
primary turn as 1 only.In such CTs the primary lead /conductor
passes through the Toridal ring type core containing secondary
winding.{Ref fig. 1.(b)}

Rated Burden: Output of the CT secondary to which it can feed
maintaining the required accuracy stipulated in the Standards (IS:
2705 or IEC: 60044-1 etc)
Total Burden: It is the sum of the total burdens (in VA)
connected to the CT secondary.
Total Burden in VA=I2x {(resistance of 2 x length of connecting
lead) + Resistance of CT Secondary winding)} + VA burden of the
meters/relays connected to it.
Note:
(i) In practice, in order to reduce the losses in the control
cable of the CT, copper control cable of 4 sq mm is used between
secondary terminals of the CTs from 220kV, 400kV and 765kV switch
yards/sub-stations to the control rooms (due to very long
distances) whereas other control cabling from switch yards to the
control rooms is done with 2.5 sq mm copper control cables. It is
for academic interest to know that resistance per Km of copper
cables, of 2.5 sq mm is 7.41 Ohms/Km and that of 4.00 sq mm is 4.61
Ohms/Km at 200C. ( As per IS: 8130 -1984).
(ii) Resistance of Lead R lead = ( x L)/A, here (Rho) is the
resistivity of copper as 1.79 x 10-8 meter at 200C and 2.16x10-8
meter at 750C.
L =2 x Actual length of the control cable lead from CT in the
switch yard to the Relay. (2 is taken as it is twice lead length ie
to and fro length). It should be in meters.
A- Area of cross section of the conductor in Square Meter.
Example: Resistance of 50 meter copper control cable with cross
section area of 4.0 Sq mm used for protection purposes is
calculated below;
R lead= ( x L)/A = (2.16x10-8x 2x50)/4x10-6.
Here 4mm2=4x10-6 Sq Meters,
L= twice the lead length=2X50 meters=100 meters.
R lead=
Dependency of secondary current on Primary current:
he primary current is independent of the secondary current. The
secondary current is governed by the Primary current only. Vice
-versa, it is not possible.
Effect of secondary open circuiting
Since in a CT Primary AT is balanced with Secondary AT, in a
closed secondary circuit (Secondary circuit is closed through
connected burden or directly) the counter flux produced by the
secondary keeps the core flux below the saturation level and as the
Primary current is independent of secondary current, the secondary
circuit should never be allowed to get open circuited with the
primary circuit carrying the current .In such situations the total
primary AT is used up in magnetizing the core leading to its
saturation. This results in increased EMF with voltage shooting up
to a very high value depending up on the primary current which is
hazardous to insulation as well as to human life.
Note: In practice, to facilitate shorting of the secondary, at
the CT terminals in the C&R panels, the CT terminals are
provided with shorting links and also sliding links.
Choice of secondary current
The CTs are generally available in 1 Amp or 5 Amp secondary
current. It is the choice of the user to choose between them, but
there are certain constraints due to which the secondary current
has to be fixed for a particular application.
The CTs are though installed in series with the equipments
(Motors/Generators/Transformers/Capacitor banks/feeders etc)
installed at some distance ,the connections from the secondary
terminals of the CTs are through leads/cables to the secondary
protective relays /meters etc which are installed on the control
& relay panels.
Where the primary current is high and the distance of the
equipment is quite much(>30mtrs) as in the case of EHV Sub
stations, the secondary current is selected as 1 Amp. Whereas when
the distance of equipments is short (generally< 30mtrs) such as
in small 33/11kV S/s, 3.3 kV, 6.6kV and 11kV indoor switchgears, 5
Amp secondary is generally selected.
The VA burden of the cable (Loss in the cable) imposed on the
CTs is governed by to the resistance of the lead/cable and square
of the secondary current flowing through it.
Say the lead (to & fro length) resistance is R ohms and the
secondary current is of 1 amps. The VA burden imposed would be
I2xR=1R=R VA, whereas in case of 5 Amp secondary current it would
be

Consumer metering and Tariff metering:
SN HT consumer Metering
Tariff metering
1 kV level - 33kV kV level -220kV2 Maximum demand
- 5 MVA, Current equivalent =87.5 A
Max load -150 MVA, Current equivalent = 394A
3 Distance of meters from CTs -15 meter
Distance of CTs from meter- 25 Mtrs (In EHV S/s yard)
4 CT ratio needed 100/5 A (Since distance is less than 30 mtrs.,
5Amp is selected.)
Note: (i) CT rating should in variably be 120% of the Max rated
current. Therefore 1.2 x 87.5=105A, Thus 100/5A CT would be
suitable.
(ii) In order to rule out any confusion about connected ratio or
also any mal practice by the HT costumer, most of the distribution
Utilities are procuring single ratio CTs for HT Consumer metering
application.
CT ratio needed 400/1A (though d i s t a n c e o f metering from
the CTs is less than 30 mtrs, but 1 Amp is used as the secondary
current for EHV CTs for all the core is 1 Amp only.
Note: ( i ) CT should have ratio of 800-400/1A, Connected to
400/1A (metering c o r e ) a l o n g with other cores for protect

PS Core
{ref. IS: 2705 (Part 4)} [Known as Px core as per IEC: 60044-1]:
Though abbreviation PS is not elaborated anywhere, however it is
assumed to be Special Protection Class CT core. This core is used
particularly where current balance is required to be maintained.
The turn ratio error is limited to 0.25%, which helps in
maintaining current balance in Differential protections &
restricted E/F protection, which is the prime requirement between
associated CTs, particularly during through fault conditions. The
5P/10P class CTs cannot match the characteristic as that of PS
class. The core of this class is such that very high current is
needed for saturation of the core.
The CT of PS class is specified in terms of;
Rated Knee point voltage Vk .
Maximum exciting (Im) at knee- point voltage or at the specified
fraction thereof.
Secondary winding resistance (Rct) of the CT at 750C.
Requirement of Vk (Knee point voltages) of some of the known
Differential relays
(i) ALSTOM Make;
(a) Type DTH31/32(Static);
Vk 40xI (Rct+2Rl),
where Rct = internal resistance of CT., Rl = Lead resistance of
cable from CT to Control panel(single length.)
(b) Type MBCH 12/13;
Vk 24 x In (Rct+2Rl), In =Relay rated Current.
(c) Type KBCH 120,130 and 140.
Vk 24 x In (Rct+2Rl), In =Relay rated Current.
(ii) ABB Make;
(a)Type RADSB;
Vk 30x In. (Rct+2.Rl+Rt+Zr),
In =Secondary Current corresponding to rated Primary
Current.
Rct = resistance of CT secondary winding.
Rl = resistance of single lead from CT to relay.
Rt = resistance of interposing CT.
Zr = reflected burden of Relay.
(iii) EASUN REYROLLE Make;
(a)DUOBIAS-M (Numeric)
Vk 4xIf (Rct+2Rl), where If=3ph fault current limited by
transformer impedance or high-set setting whichever is greater,
Rct= CT secy winding resistance, 2 Rl=twice the lead resistance
from CT to relay.
(iv) AREVA Make:
(a)MICOM P633, (Digital relay):
Vsat (Rop+Ri).k.I1,max.
Where;
Vsat =Saturation Voltage, Rop=Actual connected operating burden,
Ri =Internal burden, I1.max = Non-off set max primary Current
converted to secondary side,
k=Over dimensioning factor or Transient factor,
= 1+T, wherein =System Angular frequency and T=Primary system
time constant ie L/R of the system.
CT Saturation:
The CTs are liable to saturate if the Primary current at the
time of fault exceeds beyond its ALT limit. Such saturation may
occur if the CTs have very low ratio and the fault current exceeds
beyond 20 times of the rated current, in such cases the protective
relays (O/C) become inoperative.
Please refer to the following figure 5 depicting

wave shape of the secondary current at the time of
saturation.
Fig. 5 : Steady -state saturation with AC current
To avoid saturation the CT should develop voltage such that Vk
If. (Rb+ RCT+RL),
If= secondary fault current for fault at zone-1reach.
(Amps),
Rb=Relay burden in ohms.
RCT=Resistance of CT winding in ohms.
RL=Resistance of lead (2xsingle lead length) (ohms).
Transient saturation
In the transmission lines, since they predominantly contain
inductance, whenever fault occurs, the fault current contains
component of DC current also. In practical applications, the DC
transient current is in exponential form and does not sustain but
decays in the time equivalent to the time constant L / R {Ref.fig:
7(a) below} , L is the inductance in Henry and R is the resistance
of the transmission line in ohms up to the location of occurrence
of the fault. However in practice full line length is considered
for calculation purposes.
Due to the DC transient component of the fault current, the
total flux in the CT core is distorted and affects the secondary
current {Ref fig: 7(b) below} and the curve of CT current at
secondary will be as shown in Fig: 6. As soon as the DC Transient
vanishes, the steady state condition of the CT gets restored.
Fig.6 Transient saturation with offset current
Fig 7(a) Primary short Circuit current with DC component.Fig. 7
(b) Effect of DC component on CT Flux
As has been mentioned that the DC transient persists for a
period of about the Time constant TN of the Transmission line {ref
Fig: 6(a)}, care should be taken while procuring/selecting CT for
faithful operation of the Distance relay. The Vk should be should
be as follows.
This formula for Vk shall take care for the transient DC decay
time of all kV class of Transmission lines. The CT should develop
voltage such that
Vk If. (1+X/R). ( Rb+ RCT+RL),
Where,
X =System Reactance (ohms), R= System Resistance (ohms).
If= secondary fault current for fault at zone-1reach.(Amps),
Rb=Relay burden in ohms.
RCT=Resistance of CT winding in ohms.
RL=resistance of lead (2xsingle length)(ohms).
The term (1+X/R) is an additional term as compared to
requirement of development of voltage to avoid saturation in case
of AC saturation (ref equation in para.17).
Ratio Selection
Required CT Ratios are selected from reconnection of Primary
Terminals in majority of the cases, However in some cases the
ratios selection is provided at secondary terminals. Further, in
some cases the ratios are selected reconnecting primary terminals
as well as from secondary terminals (as the case may be).

i) Selection through Primary terminal reconnection: If there are
2 ratios say 400- 200A/1-1 A.
ii) The reconnection at primary terminals is such that for lower
ratio the winding shall be in series and for higher ratio, the
reconnection is such that the primary current shall get a parallel
path.
iii)Following sketches depict the ratio selection of ratios at
primary terminals as well as through secondary terminals;
iv) For higher ratio reconnect the primary terminals to P1-C1
and C2-P2 and for lower ratio C1-C2{ref fig8(a)}

core1:1S1-1S2, core 2: 2S1-2S2, core3 : 3S1- 3S2, core 4 : 4S1-4S2
& core 5 : 5S1-5S2 etc.
vi) Where selection of ratios are in secondary only the lower
ratio shall be 1S1-1S2, 2S1-2S2 etc and the higher ratio shall be
1S1-1S3, 2S1-2S3 etc.{Ref Fig:8(b)}
Vii) Fig.8(c) depicts the ratio selection through both Primary

It has become a practice to compact stranded conductors passing
though die or shaping rollers. This is to reduce the diameter as
well as smoothen the outer surface of conductor in one go. In case
of Medium Voltage and High Voltage Cable smooth outer surface
facilitate in reducing electrical stress on the surface of
conductor. Compacting though make the outer surface somewhat smooth
but due to pressure and drawing force the edges of wires as
flattened becomes rough and uneven. These edges develop stress at
the corner of the wire and at times can become a vulnerable point.
To obviate such a potential high stress point, segmental smooth
wires are drawn and stranded over the inner round contour thereby
eliminating the danger of any undue high stress point.
This method avoids sharp edges on the outer wires and possible
damage which may be caused to inner layers by the compacting
pressure, while also ensuring that the flexibility of normally
stranded conductor is retained.
This practice was introduced long before in UK and Europe for
EHV Cables and also for overhead conductors.
Design consideration
Calculation of Segmental wire shapes:
The segmental wire shapes required to form a smooth conductor
exterior can be calculated mathematically. In the following
solution employed by the theory that
is first propounded and a design procedure based on this is then
set out.
The following Symbols are used throughout theoretical design
calculations:
R = Inner radius of segmental layer.
Z = Outer radius of segmental layer.
t = Thickness of segmental layer
= Lay angle of segmental layer
1 = Lay angle of inner surface of segment
2 = Lay angle of outer surface of segment
l1 = Lay ratio of inner surface of segmental layer
l2 = Lay ratio of outer surface of Segmental layer
P1 = Inner radius of segment
P2 = Outer radius of segment
G1 = Clearance of inner surface of segment
G2 = Clearance of outer surface of segment
C1 = Inner chord of segment
C2 = outer chord of segment
r = Radius of segment corners
A = sum of segment areas
1 = Half the angle subtended by C1 at P1
2 = Half the angle subtended by C2 at P2
L = Lay length
L1 = Lay length of line at right angle to the segmental
L2 = Lay length of segmental wire

TheoryConsider a layer of N segments stranded round a core of
Radius R. Let the radial thickness of the layer be t and the lay
angle . Figure-1 depicts one of the stranded segmental wire.
Now consider a section through the figure at X-X and the axis of
the segment at right angle. This section is shown in fig-1
i.e. = N
Wire hat would be covered by a longitudinal straight line of the
length i.e.)
Generalising from Fig- 1
(lay angle )
Or
And
Therefore, the number of wires cross by the line = N (1+
tan2)
Assuming no clearance between the wires, the length of the inner
arc of the segmental wire is:
Length of the helix=
Rad.
Figure 2 shows the inner curve of the segment of known radius
and arc length. From which:
Therefore, The inner chord of the segment C1 is given by:
C1=Rsec
2 1 sin1
Similarly for the outer chord:
C2 = 2(R+t)Sin2
iii) Relationship of segmental layer radii and total segmental
area: Consider a cross section through the stranded cable as shown
in Fig-3
iv) Area of the annulus is = (Z2 R2).
If A is the total of the individual wire areas, then sine the
wire have a lay length the total sectional area of the wires when
cut perpendicular to the conductor axis = A Sec
The remaining area of annulus consists of the gap due to the
clearance and the space left by the rounded corners of the
segments. The space left by these rounded corners is almost the
same as the area left by a circle of radius r drawn inside a square
of side 2r. This is (4 ) r2 = 0.858 r2 . The area left by the
radiuses corners of N wires, cut an angle of 1 is:
0.858 N r sec
The clearance between segments has a constant angle. Therefore,
the fraction of the annular area taken
by clearance is:
Note: Although is used here in place of the strictly accurate ,
this does not introduce any significant error. We can therefore
write:

QP and arc QS2P = area of sector OQS2P area OQP= ; area lost due
to radiused corner S = 0.858 r2. Therefore Segment area is:
vii) Lay Ratio : In cable design , lay ratio is defined as the
lay length of a layer of wires divided by the mean diameter of the
layer. It is therefore:
tan = vii) Design Procedure:
a) Select Values for the constants: R, N, t ( and hence ),G1 and
r
b) Select a value for A or Z according to whether the design aim
is given overall diameter or a given total area.
c) If designing for a given overall diameter work through the
following formulae.
1) (hence 1)
2) (hence 2)
3)

5) (To give constant angular clearance)
6) rad
7) rad
8) C1=2P1sin1 - G1
9) C2 = 2P2sin1- G2
10) t = Z R
All the segmental dimensions are now known.
d ) Check the dimensional area using the formula:
Area = {t+p1 (1cos1)
- P2(1-cos2)} +P22(sin2-cos2)
-P21(1 sin1)-0.858r2
e) If designing for a given area first determine Z from the
formula:
Then to proceed as detailed in (c) above.

Manufacturing of conductor with Profiled Wire
Profiled Wire Drawing
As shown above once the design parameter of profiled wire is
established, wire can be drawn in a normal 13 Die Wire Rod
breakdown Drawing. Die should be made of Tungsten Carbide material.
The Die is to be profiled in a spark erosion Machine and should be
flawless. In the above case, the profiled wire can be drawn from
9.5 mm Wire Rod. Shaping is to be done during last four stages.
Take up shall be done with proper guide system to keep the profiled
wire always on the same plane. The wires can be accepted on 630 mm
Bobbin DIN Standard.
Stranding
The profiled wires are placed on the front Cage of the stranding
Machine. Lay gear is adjusted as per calculation. The wires are to
be guided through a front guiding plate and then to be led through
a cone type front guide system as is done in the case of a Flat
strip Armour wires. The front of the cage is to be modified
accordingly. Care to be taken that that the profile wires do not
turn obliquely. The profile wire guiding system thus must be
modified accordingly. Profiled wire will set plainly in place while
passing through the Die fixed on Die holder box. Never use a split
Die. A bell mouth Die is suitable for this purpose.
ConclusionFigure-5 shows a typically stranded smooth body
conductor as manufactured with profiled wires.
} To manufacture such profiled wires and stranding do not
require any special Machinery or equipment. Conventional RBD and
stranding Machine with slight modification can yield the best
result.
} Due to smooth surface Electrical stress developed is contained
to the minimum values.

} During Extrusion of Semiconducting layer thickness can be
maintained at a lower level and consumption of the material will be
less as there will be no interstice filling required.
} So also thickness and roundness and ovality can be contained
to a well within specified value.
} Overhead ACSR, AAC and AAAC can also be manufactured in the
same manner. In such cases vibration due to high wind is kept
within limited values.
} Diameter can be reduced by applying two successive layers of
stranded Flat strip wires.
} In India such conductors for MV, HV and EHV Cables can be
adopted to improve processing parameters and quality standard
