Foreword
Power is the life of blood of any growing economy and the
availability of reliable and uninterrupted power supply is a
crucial determinant for economic growth. I would like to thank
the Ministry of Power, Govt. of India for collaborating with the
UT of Daman and Diu for implementing the scheme - "Power
for All".
Daman and Diu has been a key hub of industrial activity in the
western region of India and today is home to over 2500
industrial units. The entire power requirement of the territory
is met from power allocation from the Central Generating
Stations.
The Daman and Diu Power Department is fully committed to
undertake all measures for infrastructural upgradation and
measures for efficiency improvements at the substation level
and the transmissions and distribution networks.
It is our vision to transform Daman and Diu into a model
territory with an efficient power supply framework and best in
industry standard efficiency parameters. Equally, we are
committed to supplement our generating capacity through
renewable energy sources including harnessing solar power.
Power for all programme provides us a blueprint and a
management tool for undertaking comprehensive reforms in
the power sector including the institutional arrangement and
financial plan. I am confident that in the next few years, we
shall be able to achieve the key objectives set out for us.

EXECUTIVE SUMMARY
24x7- Power for All (24x7 PFA) is a Joint
Initiative of Government of India (GoI) and State
Governments /UT Administration with the
objective to provide 24x7 power available to all
households, industry, commercial businesses,
public needs, any other electricity consuming
entity and adequate power to agriculture farm
holdings by FY 19 as per state/ UT policy. This
roadmap document aims to meet the above
objectives for the UT of Daman & Diu.
As per 2011 census, the population of UT of
Daman & Diu was 2.43 lakhs. The Electricity
Department of UT of Daman & Diu (ED-DD) is an
integrated utility having functions of distribution
and transmission licensee as UT does not have its
own generation. The UT has per capita annual
consumption of 6960 units (FY 2014-15) which is
way higher than national average of 1010 during
the same year. The same is due to about 90%
industrial consumption in the UT.
CONNECTING THE UNCONNECTED
Based on 2011 Census, there were around 557
un-electrified households in the UT but as per UT
Administration, there are no un-electrified
households in the UT at present and UT has
achieved 100% electrification.
FEEDER SEGREGATION
Keeping in view of the negligible sales in
agriculture category, the UT does not have any
feeder segregation and also has not estimated
any expenditure on this account.
24 X 7 SUPPLY
The UT is already supplying 24 hours supply to
all domestic, commercial & industrial consumers
except some interruption due to break down.
However, UT is meeting the time limits specified
in Standards of Performance by JERC.
GROWTH IN DEMAND
The UT has already achieved 100% electrification
and supplying 24 hours electricity, hence only
growth in electricity consumption from domestic
sector has been taken from upcoming households
and increase in per capita consumption for
calculation of growth in demand.
The daily per household consumption was 5.04
Units for FY 15 and it is escalated by 4.58%
annually to arrive at the daily household
consumption up to FY 19 (6.03 units/ HH). The
growth rate is based on CAGR of daily household
consumption of last 3 years in UT.
Individual category-wise growth rate equivalent
to the 5 year CAGR has been considered for other
than domestic sectors. However separate suitable
growth rate has been assumed in categories
where there has been abnormal growth due to
various one-off reasons.
Based on the above Growth rate, reduction in
losses and slow growth in power sales, demand
for ED-DD is slated to increase from 245 MW
(301 MW incl. OA) in FY 15 to 286 MW (350 MW
incl. OA) in FY 19.
SUPPLY ADEQUACY
UT does not have its own generation and is
dependent on allocation from Central Generating
Stations. The present power availability of the UT
is 291.47 MW (including share from unallocated
quota). . Recently, a 5.15 MW solar plant has been
commissioned in UT and has a program to
commission further 20.85 MW (10.16 MW Grid
Connected) solar plant and 8 MW wind capacity
in UT.
In order to meet the increasing demand, the UT
has also been allocated 42.73 MW (tentatively)
from upcoming central generating stations in a
phased manner by FY 19. However, it is expected
that 38 MW power from Ratnagiri Gas based
power plant would not be available owing to its
closure on account of fuel and financial woes.
As Daman & Diu will be having projected energy
availability of more than 100% through long-
term share in FY 19, there is no requirement of
purchase through short term power as of now.
Accordingly, UT needs to optimize its power
purchases in peak time as per requirement on
short term basis and should also look forward for
selling the surplus power to prospective deficit
states specially in case more consumers opt for
open access in near future.
ADEQUACY OF TRANSMISSION NETWORK
Presently, UT is getting feed at 400 KV and 220
KV from Western Grid through PGCIL
Substations. PGCIL has constructed a 400/220
KV, 2x315 MVA S/S in UT (at 400 KV Magarwada)
exclusively for UT and UT is also getting supply
from 400/220 KV, 3x315 MVA Ambethi S/S to
220/66 KV Magarwada S/S. The existing ISTS
transmission line capacity and transformation
capacity is adequate for meeting the present as
well as future requirements.
The transmission schemes planned in the UT
would increase the present 220 KV
transformation capacity by 460 MVA resulting in
an overall transformation capacity of 870 MVA
from exiting capacity of 410 MVA at 220 kV by
constructing 2 No of 220/66 KV S/Ss in Daman.
The existing intra/ inter-state transmission
system with the planned investment of Rs 101
Crores towards capacity addition would be
adequate to meet the expected demand of 350
MW by FY 19 as envisaged for 24x7 PFA.
ADEQUACY OF DISTRIBUTION NETWORK
ED-DD is the only distribution licensee in the UT
of Daman & Diu. It is serving more than 57,704
consumers of the UT and providing 24 hours
supply to all the consumers. UT has 9 No of 66/11
KV S/Ss of aggregate capacity of 462 MVA. The
UT has envisaged a requirement of Rs 235.63
Crores for strengthening and modernization of
distribution infrastructure in order to improve
reliability of supply and to reduce losses through
a planned capacity addition of 120 MVA at 66/11
kV level, 35.38 MVA at DT level and creation of
additional network of 7 CKM, 81 CKM and 24
CKM of 66 kV, 11 kV and LT lines respectively.
The existing distribution network with projected
addition would be adequate under projected
peak load conditions but the UT has to take
necessary steps to complete the planned works
within scheduled time period.
UT has 100% metering and T&D Losses are also
projected to be reduced slightly to 8.30% by FY
19 from present level of 8.92% but AT&C losses
are projected to reduce to 8.3% by FY 19 from
the present level of 15% by improving collection
efficiency.
FINANCIAL TURNAROUND
ED-DD is showing a net profit of Rs 46 Crores
during FY 15 and the accumulated financial profit
of ED-DD stands as Rs 173 Crores in FY 15. Power
purchase cost constitutes 92% of total expense of
the utility. In case, future increase in power
purchase expenditure is allowed as pass-through
in tariff by JERC, the utility will be in a position to
repeat the financial performance in future also. .
Capital Expenditure for proposed work would be
incurred through budgetary support of central
government and the utility already has cash (and
equivalent) of Rs 48 Crore. Hence the utility is
also comfortably placed in terms of cash flow for
financing future projects.
On the basis of above considerations, a roadmap
to achieve ‘24x7 Power for All’ targets has been
formulated and detailed in the report.

24X7 POWER FOR ALL (DAMAN & DIU) 1
CHAPTER 1: INTRODUCTION
Power sector is a critical infrastructure
element for growth of an economy. The
availability of reliable, quality and
affordable power is vital for rapid growth in
agriculture, industry and for overall
economic development of a state. For this
an efficient, resilient and financially healthy
power sector is an essential requirement
for growth of a state and economic
empowerment of the common man.
Under the Indian Constitution, electricity is
a concurrent subject. As per Electricity Act
2003, it is the duty of a distribution licensee
to develop and maintain an efficient,
coordinated and economical distribution
system in the mandated area of supply as
well as to supply electricity in accordance
with the provisions contained in the Act.
The State Electricity Regulatory
Commission (SERC), as per the provisions
of the act, specifies and enforces the
standards with respect to quality and
reliability of supply by licensees and also
monitors the performance of distribution
companies (Licensees) on the basis of
notified performance standards.
OBJECTIVES AND KEY OUTCOMES OF
THE 24X7 POWER FOR ALL – JOINT
INITIATIVE
The 24x7 Power for All (24x7 PFA) is a Joint
Initiative of Government of India (GoI) and
Administration of Daman & Diu (ADD) with
the objective to make 24x7 power available
to all households, industry, commercial
businesses, public needs, any other
electricity consuming entity and adequate
power to agriculture farm holdings.
Towards this goal the 24x7 PFA initiative
seeks to:
i. Ensure reliable 24x7 supply to
consumers within a specified period of
commencement of the program. The
hours of supply for agriculture
consumers will be decided by the State
Government/ UT Administration as per
requirement.
ii. Ensure that all unconnected households
are provided access to electricity in a
time bound manner in the next three
years i.e. by end of FY 19.
iii. Ensure adequate capacity addition
planning and tie ups for power from
various sources at affordable price to
meet the projected power demand in
future.
iv. Strengthen the transmission and
distribution network to cater to the
expected growth in demand of existing
as well as future consumers.
v. Assess the financial measures including
optimizing investments and undertaking
necessary balance sheet restructuring
measures to ensure liquidity in the
finances of the utility.
vi. Put in place a strategy to ensure
reduction of AT&C losses as per the
agreed loss reduction trajectory and
methodology and steps required to be
taken at every level of distribution.
vii. Identify steps for implementation and
adoption of modern technologies to
monitor reliability of supply.
viii. Identify steps for monitoring timely
commissioning of various generating
plants and transmission and distribution
infrastructure to meet the expected
growth in demand.
24X7 POWER FOR ALL (DAMAN & DIU) 2
ix. To take measures for meeting the
performance standards as laid down by
the JERC.
In the document, an action plan has been
drawn to achieve the above aims and
objectives. The plan will be executed by
the Administration of Daman & Diu with
the support of Government of India,
wherever necessary, as per their
approved plans, schemes and policies.
METHODOLOGY FOR PREPARATION
OF THE ACTION PLAN FOR 24X7
POWER FOR ALL
The plan aims at the following:
1. bridging the gap between the demand and supply for the already identified/registered consumers and other consuming entities,
2. connecting the unconnected households and unconnected farm holdings.
Accordingly the methodology adopted to
prepare the ‘Action Plan’ for 24x7 PFA
includes inter-alia:
1) Projection of average per day
consumption of rural and urban
households based on respective
historical compounded annual growth
rates (CAGR) during the past five years.
2) Projection of demand of
commercial, industrial and agriculture
consumers based again on past data and
historical CAGR recorded during the past
five years.
3) Assess the power requirement of
un-electrified households and draw up a
time bound plan for electrification of all
households.
4) Project the annual energy
requirement and maximum demand by
aggregating the requirement of all
consumer categories and applying an
appropriate load factor.
5) Draw up a broad plan to meet
power demand in future through
State’s own upcoming generation
resources.
Allocation from upcoming central
sector power plants
Quantum for additional procurement
required.
6) Assess the additional energy
requirement for providing 24x7 power
supply to all households in the state as
well as to other consumer categories and
determine financial implications on
utilities for procuring additional energy
and its implication on tariff.
7) Assess the adequacy of the network -
both inter-state and intra state
transmission as well as distribution so as
to meet the increased / expected /
projected power requirement of all
consumer categories of the state.
8) To incorporate futuristic initiatives
like smart grid, energy efficiency
measures etc.
9) Conduct sensitivity analysis for cost of
service and resulting financial gap under
multiple scenarios, namely, tariff hike,
reduction in power procurement cost
and increase in interest and moratorium
period and AT&C loss reduction, etc.
10) Set monitorable targets to achieve the
goal of 24x7 Power for All in a cost
effective manner to the consumers of the
state.

Daman and Diu were incorporated into the Republic of India on December 19, 1961 from
control of Portugal. The territory of "Goa, Daman, and Diu" was administered as a single Union
Territory until 1987, when Goa was granted statehood, leaving Daman and Diu as a separate
union territory. Each enclave constitutes one of the union territory's two districts. Daman and
Diu are approximately 650 kilometers away from each other by road.
The economy of Daman and Diu depends largely on agriculture, mineral viz. salts and industries
viz. fishing, tourism, distillery. The major agricultural products are paddy, ragi, groundnut,
pulses and beans, wheat, banana, sapota and mango. There are some more than 600 small scale
industries present in Daman and Diu. The main industries are located at Somnath, Dabhel,
Bhimpore and Kadaiya.
The area profile of districts is summarized in Table 26 in Annexure-1. Further, the district wise
population details as per 2011 Census is summarized in Table 27 in Annexure-1.
The Electricity Department of Daman & Diu (ED-DD) is responsible for supply of uninterrupted
& quality power to all categories of consumers in Daman & Diu at the most economical rates.
The (ED-DD) is engaged in the procurement, transmission and distribution of electricity to the
various consumer categories in the Union Territory of Daman and Diu. It does not have its own
power generation station (except small Solar Plants of 4 MW) and completely rely on the
Central Sector Generating Stations (CSGS) in Western Region to meet its energy demand. ED-DD
also has some allocation from Eastern Region Central Generating Stations.
The power sector of the UT is regulated by Joint Electricity Regulatory Commission (JERC) for
the state of Goa and Union Territories.

CHAPTER 3: CONSUMPTION PATTERN AND
ELECTRIFICATION STATUS
ELECTRIFICATION STATUS AND PER-
CAPITA CONSUMPTION
The population of Daman & Diu has grown
from 1,58,204 in 2001 to 2,43,247 in 2011
at a decadal CAGR of 4.40%. This growth
rate has been considered for estimating the
population beyond 2011. Based on the
annual energy availability from FY 11 to FY
15, the per-capita consumption of
electricity in the period has been as shown
below:
Figure 1: Per-Capita Consumption of
Electricity (kWh per person) in recent years
(CEA)
As can be seen from above figure that
there are large fluctuations in per capita
consumption of electricity during last
year. The reason for the same is that most
of power in the UT is consumed by
industries whose operations and
electricity consumption depends on
economic scenario and various policy
related reasons and many of the
industrial consumers have opted for
meeting their demand through open
access (OA).
STATUS OF ELECTRIFICATION AND
PROJECTION HOUSEHOLDS FY 15
District-wise electrification in urban and
rural areas1 is detailed in Table 28 in
Annexure-2.
The summary of electrified and un-
electrified households as per 2001 and
2011 census and projections for FY 15
based on CAGR for past 10 years is
tabulated below:

From above it is inferred that:
1 As per the information available in
http://censusindia.gov.in/
24X7 POWER FOR ALL (DAMAN & DIU) 5
In 2011, only 21.12% of the households
were in rural areas as compared to
64.33% in 2001 signifying migration of
population from rural areas to urban
areas and de-notification of rural areas as
urban areas
In 2011, 99.08% households were
electrified up from an already high level of
97.76% electrification in 2001
In rural areas also electrification was s at
very high level of 98.29% in 2011. The
number of un-electrified households in
rural areas have also registered steep
drop from 2001 to 2011 (in percentage
terms) due to overall decrease in number
of rural population and households.
Overall number of households has grown
at a decadal CAGR of 5.81% with urban
and rural areas showing decadal growth
rate of 14.54% and - 5.35% respectively.
Expected numbers of Electrified and un-
electrified households in both urban and
rural areas have been arrived for FY 15 by
projecting them at decadal CAGR of all
households in the UT. As per projections,
about 296 households are expected to be
un-electrified in the UT in FY15 but as per
UT Administration, the UT has achieved 100
% electrification and there is no un-
electrified household in the UT.
The above projected figures, derived by
extrapolating Census 2011 data, do not
match with the no of consumer records of
the UT (ED-DD) for FY 15.
Following variations were observed in
figures submitted by ED-DD and census
projections:
a) Against the projections of 75,671
electrified households in FY 15, there
are 45,195 electrified registered
consumers on record of ED-DD.
b) Additionally ED-DD has submitted that
all the households have been electrified.
Considering that even by census
projection only negligible households
are expected to be un-electrified, this
submission can be accepted.
This anomaly/discrepancy in figures was
discussed with ED-DD.
The difference in census projections and
records of ED-DD is due to the fact that a
household may have single electrical
connection but may have been feeding more
than one household as a combined family
which have been considered as separate
household in census record.
For the projection of daily household
consumption (for the estimation of
demand) of both rural and urban
consumers in future years, following
methodology has been adopted:
The figure of the households in FY 15 as
given by ED-DD has been considered. In
view of already high electrification in
Daman & Diu submission of 100%
electrified households has also been
considered. Since the area of the UT is very
small and consumption pattern/trend in
such small area may not vary significantly,
rural and urban consumers have been
treated as a homogeneous group for
projection of future demand
Based on the above, the numbers of
households in urban and rural areas of
Daman & Diu in FY 15 have been arrived at.
Accordingly, the demand projections for the
UT have been worked out in the next
chapter.
24X7 POWER FOR ALL (DAMAN & DIU) 6
CHAPTER 4: DEMAND AND SUPPLY SCENARIO
PRESENT POWER SUPPLY
POSITION
The actual energy and demand scenario of
UT during the past 6 years is shown below:
Figure 2: Energy Requirement vs.
Availability2 (in MU)
Figure 3: Peak Demand vs. Peak Met (in MW)
The peak demand and energy deficit is
being progressively bridged by ED-DD.
The reason for fluctuation in yearly
demand and supply scenario is due to
fluctuation in demand from Industrial
consumers which on average comprises
90% of total energy consumption.
2 As per the data available in the CEA
As per the UT, in FY 15, barring a few
operational issues, the supply was generally
of the order of around almost 24 hours only.
DEMAND PROJECTIONS
The present energy requirement of Daman
& Diu during FY 15 was 2086 MU out of
which 336 MU of energy is consumed by
open access consumers. Similarly out of 301
MW of maximum demand only 245 MW is
met by ED-DD and the rest was from open
access consumers. Since all households in
the UT are already electrified and ED-DD is
providing 24 x 7 Power to different
categories (except due to
operational/maintenance reasons) the
trajectory of demand is not expected to
alter significantly from business as usual
scenario on operationalizing of 24 x 7
Power for All scheme. Separate CAGR have
been utilized to project demand of domestic
consumers and other categories of
consumers for projection of demand by FY
19.
DETERMINATION OF AVERAGE
GROWTH RATE IN DAILY HOUSEHOLD
CONSUMPTION
Since, separate numbers and consumption
of urban and rural consumers are not
available, per capita consumption of urban
and rural consumers has been taken as
same in UT and the average household
consumption comes out as 5.04
units/households in FY 15.
The broad approach for projection is
highlighted below:
The daily household consumption has been
escalated by 4.58% annually in both rural
and urban areas based on CAGR of daily
household consumption of last 3 years.
24X7 POWER FOR ALL (DAMAN & DIU) 7
The sales in categories other than
household have been considered to increase
at the respective CAGRs of past 5 years.
However, past trends show negative growth
in consumption by the agriculture sector
hence growth rate has been taken as zero
for this consumer category. Similarly CAGR
of 5 years in categories of temporary supply
and Public Water Works is very high due to
low base of FY 10. Hence in case of
temporary supply CAGR of 0% has been
considered for projection of energy sale. For
projection of energy sales to Public Water
Works, growth rate of power sale between
FY 13 and FY 14 has been considered.
DETERMINATION OF CONSUMPTION
OF HOUSEHOLDS (ELECTRIFIED AND
UN-ELECTRIFIED)
The average daily household consumption
of existing households in FY 15 has been
arrived at by dividing the total sales to
domestic category (as per assumption
stated above) by number of electrified
households considered in FY 15
respectively.
The projected daily household consumption
in the UT is shown below:
Figure 4: Projected Daily Household
Consumption Electricity (kWh per person)
for future years
However, it may also be kept in view that
the geographical features of the UT (i.e. the
location, accessibility, weather) along with
current tariff levels play a significant role is
determining the current and future
demands.
The number of electrified households is
expected to grow at the decadal CAGR of
5.81% due to construction of new
Households in UT.

DETERMINATION OF CONSUMPTION
OF OTHER CONSUMERS
For projection of sales from FY 15 to FY 19,
the CAGR of previous 5 years has been
considered for other categories, except for
agriculture, Public Water Works and
Temporary supply as stated above.
Based on this, the category-wise sales is as
per table below:
Table 3: Projected Category-wise Sales (In
MU)
Categories CAGR Projections
Considered FY 16 FY 17 FY 18 FY 19
Domestic Category 92.00 101.80 112.64 124.64

Grand Total 1625.30 1656.98 1690.49 1726.00
As seen from above, the share of industrial sales (LT, HT) will decrease from the 91.02% to
87.86% of overall consumption of the UT of Daman & Diu whereas the share of domestic sales
will increase from 5.21% to 7.70% from FY 15 to FY 19.
ENERGY AND DEMAND
REQUIREMENT
The trajectory for AT&C loss reduction as
submitted by ED-DD has been taken into
account for preparing this roadmap
document.
Considering the collection efficiency
proposed by ED-DD, the T&D (including
intra-state losses) and AT&C Loss trajectory
is shown below:
Figure 5: Projected Loss Reduction
Trajectory
Based on the loss reduction trajectory
approved as above, the energy and demand
requirement for the future years is
tabulated in table 4 below:
The load factor has been taken as 75.16% as
considered in 18th EPS for FY 2014-15.
As seen from the above, the maximum
demand requirement of the UT is projected
to increase from 245 MW in FY 15 to 286
MW in FY 19 assuming an unchanged
annual load factor of 75.16%. The low
growth in demand is primarily due to
reduction in AT&C loss and sluggish growth
in industrial consumers which forms
mainstay of power demand contributing
almost 90% of sales in the UT and option
for OA for industrial consumers.
As per projections made in 18th EPS of CEA,
the projected energy demand and peak load
for the UT of Daman & Diu was 3143 MU
and 500 MW in FY 19 as against the now
calculated energy demand of 2307 MU and
peak load of 350 MW in FY 19 (including
Open Access). The reduction in projection is
due to low growth of sales to industrial
consumer as per actual as compared to
24X7 POWER FOR ALL (DAMAN & DIU) 9
assumption taken in 18th EPS.
ENERGY CONSUMPTION IN DIU
In FY 2014-15 Energy Consumption in Diu
was 44.50 MU out of total 1595.28 MU i.e.
2.78% of total sales. Additionally it has
100% household electrification and
industrial demand of 10 MU only. Hence
there is very low scope of growth of
domestic as well as industrial demand.
Keeping above facts in view, the analysis of
Daman and Diu has been done on combined
basis and not for Daman and Diu separately
for 24 x 7 Power for All report.
LOAD CURVE
As can be seen from above graph, the
seasonal load-curve of the UT is almost flat
with value ranging from +/- 5%. The same
is also possible as most of the load is
industrial which do not exhibit much
seasonal variation. It is also note-worthy
that there is not much difference between
peak and off-peak demand. The UT has ToD
tariff for industries which forces them to
consume more in off-peak period.
An assessment of the adequacy of
generation, transmission and distribution
infrastructure for meeting the projected
annual energy demand of 1882 MU and
peak demand of around 286 MW( 350 MW
with OA) has been made which is covered in
the following chapters.

Maximum Demand (UT) 326 334 342 350
However, the energy requirement and max demand may vary in case more industrial
consumers opt for open access, but UT has to establish & maintain the transmission system to
handle the total projected power of the UT.
24X7 POWER FOR ALL (DAMAN & DIU) 10
CHAPTER 5: GENERATION PLAN
CUMULATIVE GENERATION
AVAILABILITY
ED-DD does not have its own generating
stations baring small solar plants
commissioned recently. It is fed by central
generating stations located mainly in
western region and Long Term allocation of
the UT from CGS and IPP as on 31.03.2015
stands at 291.47 MW as detailed in table
below. The same also includes 137 MW
unallocated power from CGS which has
been allocated by Central Government to
Daman & Diu.
Station wise details are at Table 30 in
Annexure – 4. In addition to the above
capacity, some unallocated power from CGS
at the disposal of Central Government is
also allocated to Daman & Diu from time to
time.

Gas 100.35 34.43%
Nuclear 15.45 5.30%
Total 291.47 100%
Grand Total 291.47
Daman & Diu has met a maximum demand
of 245 MW in FY 15 and the present annual
energy requirement of the UT is of the order
of 1750 MU. However Ratnagiri Gas plant
from which it has allocation of 38 MW is not
functioning now. The UT has been drawing
power through UI pool also to meet any
deficit in supply especially in peak period.
AS per the estimates, the maximum demand
of UT is expected to increase to 286 MW in
FY 19 and the energy requirement is
projected to rise to 1882 MU in FY 19.
The actual energy availability from various
sources in FY 14 and FY 15 is summarized
below:
Figure 6: Availability Mix from Various
Sources in FY 14 and FY 15 (in MU)
During FY 15, about 90% of the power has
been sourced from NTPC owned
generating stations, whose average rate
has increased from Rs. 3.16/unit in FY 14
to Rs. 3.23/unit in FY 15.
Another 7% power sourced from NPCIL
owned nuclear power plants whose
average rate has decreased from
Rs.2.75/unit in FY 14 to Rs. 2.64/unit in FY
15.
The UT has also been allocated power
from Ratnagiri gas power plant. However
being costly the unit is not scheduled as a
result the fixed cost is loaded on lesser
number of units leading to high power
purchase cost of Rs 19.85/unit in FY 15.
PLANNED CAPACITY ADDITION
UT has the allocation of about 42.73 MW
from CGS which are planned to be
commissioned up to FY 19. Along with the
24X7 POWER FOR ALL (DAMAN & DIU) 11
same, 20.31 MW power is expected from
Solar and wind plants. The additional
capacity available from various sources
(along with the expected year of
commissioning) is summarized below:

The table below summarizes the availability of power from various sources including the
existing and upcoming capacity (excluding allocation from Ratnagiri Gas Power plant)
availability in FY 19:

24X7 POWER FOR ALL (DAMAN & DIU) 12
As seen from above, after the completion of
allocated CGS, the capacity availability from
FY 15 to FY 19 for UT would be around
296.20 MW from conventional sources
along with 20.31 MW from Solar Plants.
(Date of commissioning of CGS are based on
the latest expected dates of commercial
operation as available with Central
Electricity Authority). It has been assumed
that the UT will not draw any power from
Ratnagiri Gas based Power Plant.
However, the availability of the stations has
been appropriately factored for
computation of energy availability from
existing and upcoming generating stations.
Accordingly, the projected energy
availability from the above mentioned
sources for future years is summarized in
table below.
Table 8: Projected Energy Availability from Long Term Tie-Ups (in MU)

Additional Tie-up Required (80% PLF) on RTC Basis (in MW) 0 0 0 0
Additional Energy Required on Short Term Basis (in MU) 128 0 0 0
It is seen from above table that the
availability from already tied-up share will
remain in range of 92%-102% of the energy
requirement which can be termed as
adequate.
As Daman & Diu will be having projected
energy availability of more than 100%
through long-term share in FY 19, the UT
has to just optimize the power purchase
and sale planning. The availability of excess
energy might be more in case more
industrial consumers opt for open access in
future.
It is also worth mentioning that the long-
term tie-ups consist of 137 MW from un-
allocated power of western region which
can’t be considered as reliable source in the
long run. Hence proper substitute of the
same should be searched. The breakup of
the power allocation from firm/
unallocated/ specific quota of power plants
is given in in Annexure-4.
FUND REQUIREMENT
As all the UT allocations is from CGS, there
is no fund requirement for conventional
generation for UT. However, the fund
requirement for solar projects in UT is
summarized below:
Table 9: Fund Requirement for UT Generation Projects (in Rs Crores)
Sl. No. Category Fund Requirement (in Rs Crores)
FY 16 FY 17 FY 18 FY 19 Total

Total Fund Requirement (Generation) 55.00 10.00 45.00 45.00 155.00
24X7 POWER FOR ALL (DAMAN & DIU) 13
However the same has not been considered
for capex requirement in projected audited
account of ED-DD and the cost has been
projected to be incurred as power-purchase
cost in future years.
ACTION POINTS FOR THE UT
OPTIMIZED POWER PURCHASE AND
SALE PLANNING
As seen from previous sections, there may
be some surplus energy (1%-11%)
available with the UT in coming years. The
UT needs to optimize its power purchase
and should look forward for selling the
surplus power to prospective deficit states
so as to earn revenue for the UT. It is also
expected that cost of power procured from
central generating stations could increase in
near future. Hence ED-DD may go for Case-I
bidding in order to minimize its power
procurement cost. If successful in the
endeavor, it can also surrender unallocated
power assigned to it from CGS
TIMELY COMPLETION OF PLANNED
SOLAR POWER PLANTS
The UT will take appropriate action to
ensure timely commissioning of 6 MW solar
plant, 1.16 MW Solar Rooftop and 8 MW
wind power plant as per schedule.
ACTION POINTS FOR GOI
Ministry of Power is requested to allocate
more power to the UT in Peak-Period from
CGS as presently less power is allocated to
the UT in Peak period as compared to off-
peak period. MOP may also confirm the
unallocated quota of power to firm power
to UT.
24X7 POWER FOR ALL (DAMAN & DIU) 14
CHAPTER 6: TRANSMISSION PLAN
EXISTING INTER-STATE
TRANSMISSION SYSTEM (ISTS)
Power supply to the Daman District is
received through dedicated 220 kV lines
from PGCIL 400/220 kV Sub Station at
Ambethi and 400/ 220 KV Magarwada
(PGCIL). Diu gets power from 66 kV Una
(Malala) substation through 66 kV double
circuit line emanating from 220 /66 kV
Kansari substation of GETCO. However
Ambethi Sub-station also caters to
requirement of Gujarat and Dadra and
Nagar Haveli.
PLANNED INTER-STATE
TRANSMISSION SYSTEM (ISTS)
PGCIL is in process of commissioning
Magarwada - Boisar section of Contingency
arrangement of Navsari – Magarwada –
Kala – Vapi 400 kV line. The section would
be available in FY 17.
EXISTING POWER EVACUATION &
INTRA STATE TRANSMISSION
SYSTEM
At present, there is only one 220/66 KV
Sub-stations in the UT at Magarwada with
transformation capacity of 410 MVA
meeting the max demand of 301 MW during
2014-15.
Existing transmission lines are detailed in
below table:
Table 10: Intra-State Transmission Lines in Daman & Diu
Line Name Length
(Ckt. km)
Conductor
Ambethi-Magarwada (ED-DD)
25 Zebra (D/C)
Magarwada (PGCIL)- Magarwada (ED-DD)
1 Zebra (D/C)
Applying power factor of 0.9 and assuming
all transformers have their individual
maximum demands proportional to their
ratings, it results in 81% loading of
transformers at present under maximum
demand conditions.
PLANNED INTRA-STATE
TRANSMISSION SYSTEM (ISTS)
The existing 220/66 KV S/S at Magarwada
has the transformation capacity of 410 MVA
by addition of additional 160 MVA
transformer recently. The sub-station is
loaded to its optimum capacity and there
will not be any leftover clearance for
meeting the load growth in subsequent
financial years.
Considering the future load growth in the
UT, Electricity Department has proposed to
establish two 220/66 KV sub-stations -
1x160 MVA + 2x50 MVA S/S at Ringanwada
and 2 x 100 MVA S/S at Dabhel, Nani
Daman along with related 220 kV D/C
transmission lines.
The schemes will provide alternate 220 KV
power source to the UT of Daman and will
improve the voltage regulation of the
electrical system and reduce the line losses
by ensuring extra High voltage transmission
of electricity. It will improve power supply
and will ensure stand by feeding
arrangement in case of major breakdown in
Magarwada circuit. The target date of
commissioning of these transmission lines
and sub-stations is till FY 2017-18. The
details are shown in below tables: Table 11: Planned Intra-state Substations

The maximum demand of UT is projected to
reach 286 MW by 2019 with additional 65
MW open access consumption and the
available transmission system would be
adequate to meet the power requirement of
Daman & Diu even during nil internal
renewable generation.
Furthermore assuming diversity factor of
1.2, power factor of 0.9 and assuming all
transformers would have their individual
maximum demands proportional to their
ratings under maximum demand conditions
in FY 19 the transformers would be loaded
at 54%
IMPROVEMENT AND
MODERNISATION OF 220/66 KV
SUB-STATION AT MAGARWADA
The existing 220/66 KV S/S at Magarwada,
Moti Daman was commissioned in the year
2003. Due to heavy salinity climate in
Daman, the S/S equipment like breakers,
isolators and other items are corroded and
required to be replaced for better
performance and proper functioning of the
S/S.
INTRA-STATE LOAD FLOW STUDY
BY PGCIL
PGCIL has conducted load flow study for
Intra-state transmission system of Daman
and Diu. The study has shown considerable
overloading of 66 kV sub-transmission lines
feeding sub-stations at Magarwada,
Varukund and Kachigam with loading as
high as 127% under peak conditions.
However with commissioning of new sub-
stations the load will be disbursed and
hence peak loading is expected to come
down. ED-DD should also plan
strengthening of sub-transmission lines
specially those directly emanating from 220
kV sub-stations.
It has also been observed in the study that
voltage at 66 kV sub-stations fall to as low
as 59 kV at time of overloading. To improve
the same the utility will have to strengthen
existing transmission lines and to install
capacitor banks.
SYSTEM ANALYSIS UNDER PEAK
DEMAND OF 350 MW IN FY 19
GENERAL
The transmission system of Daman has
been planned based on the results of load
flow study carried out to assess the
adequacy of the power drawl by the UT
corresponding to FY 19 condition.
BEST PRACTICES ADOPTED BY ED-
DD FOR TRANSMISSION NETWORK
ED-DD has adopted following practices to
improve reliability/efficiency of its
transmission system.
On-line oil drying system to improve
break-down voltage
Monthly thermal vision with thermal
camera to identify areas of preventive
maintenance
EMS system
UT has outsourced the O&M of 220/66
KV Magarwada S/S since its inception
in 2003 and the system is working well.

CHAPTER 7: DISTRIBUTION PLAN
CONNECTING THE UNCONNECTED
HOUSEHOLDS
As per ED-DD, there is 100% electrification
in UT hence there is no requirement of
connecting unconnected households.
However proper system to electrify
upcoming households in optimum time is
required.
EXISTING DISTRIBUTION SYSTEM
ED-DD is the only distribution licensee in
the UT of Daman & Diu. It is serving more
than 57,704 consumers of the UT and
providing 24 hours supply to all the
consumers. The category wise number of
consumers and energy being consumed
during 2014-15 is as under-

NORMAL DEVELOPMENT WORKS AND
RELEASE OF SERVICE CONNECTIONS
The scheme for Normal Development
Works & Release of Service connection is a
normal develop scheme being taken up by
ED-DD for augmentation of existing
electrical network to cope with the loads on
the system due to release of various type of
service connections to the consumers in the
UT. ED-DD receives several applications
from LT Domestic, LTC, LT Ag., LT Industrial
and HT Industrial consumers throughout
the year and releases these loads by
augmentation of existing system by erecting
new transformer center, lines and other
related accessories. Therefore, the main
objective of works proposed under ND & SC
scheme are to erect few transformer
centers, LT/HT lines and service connection
lines etc, to cope with prospective loads
coming during the year and are continuous
in nature. The works under this scheme are
24X7 POWER FOR ALL (DAMAN & DIU) 18
carried out on the basis of 15% revenue
return per annum.
CAPITAL EXPENDITURE WORKS FOR
66/11 KV SUB-STATIONS AND 66 KV
SUB-TRANSMISSION LINES
The main objectives of works under this
head is to meet the increasing industrial as
well as other categories of load during the
12th five year plan period and to clear the
pending application for industrial
connection as well as to provide power to
meet the increased loads in Daman & Diu
sectors.

CAPITAL EXPENDITURE WORK AT 11
KV LEVEL
Earlier, power supply to consumers having
contracted load between 100 kVA to 1500
kVA was at 11 kV and for more than 1500
kVA at 66 kV. However, as per JERC Tariff
Order for FY 2014-15, the power supply to
consumers having contracted load between
100 KVA to 4000 KVA (including licensee
common feeders and express
feeders/dedicated feeders) shall generally
be at 11 KV and for more than 4000 KVA up
to 25000 KVA at 66 KV. Hence, to
strengthen the 11 kV feeders to cater to the
enhanced load, this scheme has been
launched and is estimated to cost 9.00
Crore. The detail of capacity addition under
the scheme is given as under
Table 17 Capital Works proposed at 11 kV

ASSESSMENT OF ADEQUACY OF
DISTRIBUTION SYSTEM
AT 66/11 LEVEL
The existing aggregate 66/11 KV
distribution transformer capacity of ED-DD
is about 462 MVA in FY 15.
Further, an additional transformer capacity
of 120 MVA is planned to be added by FY 19
under various initiatives which will result in
overall 66/11 kV transformation capacity of
582 MVA by FY 19.
24X7 POWER FOR ALL (DAMAN & DIU) 19
Given that the billed energy to consumers at
or above 66 kV in FY 15 totals around 41
MU which at load factor of 75.16% comes
out at 6 MW. This leaves a demand of 295
MW (=301-6) to be met at LT (415V) and
HT Level (11 kV) which corresponds to 327
MVA considering a power factor of 0.9.
Against this peak demand, the aggregate
installed capacity of 66/11 kV transformers
in the UT is 462 MVA. This translates to an
average loading of 70.88% on 66/11 kV
transformers under peak demand
conditions.
Following the same logic and taking the
projected peak demand of 350 MW in FY 19
and sales to consumers at 66 kV at 43 MU
the load at or above 66 kV level comes out
to be 7 MW
Correspondingly, the demand met below 11
kV comes to around 343 MW (=350-7)
which corresponds to 382 MVA considering
a power factor of 0.9. Against this peak
requirement, the installed capacity of 66/11
kV in FY 19 is projected at 582 MVA. This
translates to an average loading of 65.57%
on 66/11 kV transformers under peak
demand conditions which seems to be
adequate
AT 11/.04 KV LEVEL
The existing aggregate 11/ 0.4 KV
distribution transformer capacity of ED-DD
is about 177.37 MVA in FY 15.
Further, an additional transformer capacity
of 35.38 MVA is planned to be added by FY
19 under various initiatives which will
result in overall distribution transformation
capacity of 212.77 MVA by FY 19.
Given that the billed energy to HT/EHT
consumers in FY 15 totals around 1298.09
MU which at load factor of 75.16% comes
out at 197 MW. Additionally 56 MVA OA
consumption is at HT/EHT level. This leaves
a demand of 48 MW (=301-197-56) to be
met at LT (415V) level which corresponds
to 53 MVA considering a power factor of
0.9.
Against this peak demand, the aggregate
installed capacity of DT transformers in the
UT is 177.37 MVA. This translates to an
average loading of 29.91% on distribution
transformers under peak demand
conditions.
Following the same logic and taking the
projected peak demand of 350 MW in FY 19
and sales to HT consumers at 1350 MU the
load at HT/EHT level comes out to be 205
MW. Further in FY 19 OA demand will be 65
MW
Correspondingly, the demand met below 11
kV comes to around 81 MW (=350-205-63)
which corresponds to 90 MVA considering a
power factor of 0.9. Against this peak
requirement, the installed capacity of
distribution transformers in FY 19 is
projected at 212.77 MVA. This translates to
an average loading of 42.24% on
distribution transformers under peak
demand conditions.
AT&C LOSSES
The actual and projected AT&C losses is
summarized below:
Figure 7: AT&C Losses over the years
The AT&C losses which were order of
15.72% in FY 14 is slated to decrease to
24X7 POWER FOR ALL (DAMAN & DIU) 20
8.30% by FY 19 as submitted by ED-DD. The
UT is undertaking a number of steps such as
testing of electricity meters, replacement of
defective meters and monitoring of prompt
payment of energy bills and recovery of
arrears for reduction of AT&C losses
RELIABILITY INDICES
ED-DD has reduced System Average
Interruption Frequency Index (SAIFI) from
116.12 in FY 13 to 68.74 in FY 15. However
the same is still quite high and translate to
figure of every interruption once in 4-5
days. ED-DD also recorded SAIDI of 250
hours in FY 15 and as defined in JERC
Standards of Performance (SoP)
Regulations, 2009, it translates to Wire
availability of 97.15%. As per the
regulation wire availability needs to be
raised to 98%. ED-DD will take steps for
quick fault location and system restoration
to improve customer satisfaction. IT
initiative as described in next section would
assist ED-DD in achieving high reliability
indices.
ED-DD has also set-up complaint center
within 5 Kms radius in the UT with
technical staff having logistic support to
reduce power out time of consumers.

CHAPTER 8: RENEWABLE ENERGY INITIATIVES
ACHIEVEMENTS IN RENEWABLE
ENERGY
Currently UT of Daman & Diu has 4 MW
Grid connected Solar power plants
available, out of which 1 MW capacity is
located at Magarwada in Daman and 3 MW
capacity is located in Diu. The plants have
been commissioned recently in June 2015
and July 2015 respectively.
RENEWABLE ENERGY POLICIES IN
THE UT
Currently the UT is in process of
formulating renewable policy.
RPO AND REC STATUS IN DAMAN
& DIU
RENEWABLE PURCHASE
OBLIGATION – CURRENT STATUS
Joint Electricity Regulatory Commission has
notified JERC (Procurement of Renewable
Energy) First Amendment Regulations,
2014 in which it has specified Solar and
Non-Solar Renewable Purchase Obligation
for distribution licensees at a defined
minimum percentage of the total
consumption of all the consumers in its area
during a year.
As per “JERC (Procurement of Renewable
Energy) Regulations, 2010" If the Obligated
Entity does not fulfill its commitment
towards Renewable Purchase Obligation
during any year as provided under JERC
Regulations, and also does not purchase
adequate certificate for meeting the
shortfalls, the Commission may direct the
Obligated Entity to deposit into a separate
RPO Fund such amount as the Commission
may determine on the basis of the shortfall
in units of RPO and at the forbearance price.
The defaulter shall also be liable for penalty
as may be decided by the Commission
under section 142 of the Act
notwithstanding its liability for any other
action under prevailing laws:
Table 19: Existing Status of RPO Compliance
Particulars FY 12 FY 13 FY 14 FY 15

In MU 5.31 7.45 7.02 9.73
However ED-DD has made negligible
Purchase under non-solar and solar
categories both from sources as well as REC
Markets. The cumulative solar RPO from FY
11 to FY 15 comes out to be 33.65 MU out of
which ED-DD has only purchased 0.6 MU
from solar. Thus total deficit in Solar RPO
comes out to be 33.05 MU. The cumulative
non-solar RPO from FY 11 to FY 15 comes
out to be 180.35 MU out of which ED-DD
has purchased 98.38 MU worth of non-solar
REC from power exchange. Thus total
deficit in Solar RPO comes out to be 81.97
MU. According as per the regulations, JERC
has provisioned an amount of Rs 21.83
Crore for fulfilling RPO. However the
provision has been made at floor price of
REC instead of forbearance price.
As per National Tariff Policy, 2016 the UT
will have to procure 8% of its energy needs
from solar plants by March 2022 which
translates to 189 MW. Keeping in view
small size of the UT, it can have PPA with
24X7 POWER FOR ALL (DAMAN & DIU) 23
solar plants situated outside the UT to
achieve the target.
RENEWABLE ENERGY CERTIFICATES
JERC has designated Executive Engineer ED-
DD as the State Agency for accreditation
and recommending the renewable energy
projects for registration with Central
Agency and to undertake certain others
functions as mention in the Regulation 3 of
JERC Procurement of Renewable Energy
Regulations 2010.
The Commission through sub clause 3.3 of
above said regulation has also provided the
responsibility to MNREDA for intimating
quarterly status of RPO compliance by the
distribution licensee to the Commission.
However as of now no renewable generator
has been accredited for REC certificate by
the Nodal agency.
PLAN FOR RENEWABLE ENERGY
ADDITION UP TO FY 19
PROPOSED ADDITION OF SOLAR
CAPACITY
ED-DD has planned to commission 6 MW
grid connected solar plant at Malala, Diu.
The work order of the same is issued to M/s
Ujjas Energy Ltd. The cost of the same is
expected to be Rs 51 Crore and the plant
will be commissioned in FY 2016-17 (or
end of FY 2015-16).
PROPOSED ADDITION OF 8 MW
WIND POWER
ED-DD to tap available wind resource in the
UT has planned to add 8 MW wind power.
The same would also be used to fulfil non-
solar RPO as per JERC Regulation. The
proposed wind mill would be
commissioned by FY 19 and is expected to
cost Rs 100.00 Crore.
PROPOSED SOLAR LIGHTENING
SYSTEM AND SOLAR HEATER
The scheme envisage providing of back
ended subsidy to the extent of 30 % of the
cost to the consumers belonging to above
poverty line (APL) category, in line with the
provision made by the Government of India
in the Jawaharlal Nehru Solar Mission
(JNNSM). However, to provide further
incentive to the consumers of below
poverty line category (BPL) to use such
non-conventional energy device, it is
proposed to provide 50 % back ended
subsidy to them. It is proposed to provide
one solar lantern of 13 Watts capacity and
one solar water heater of capacity. The
outlay of scheme is Rs. 1.65 Crore.
SCHEME FOR PROVIDING OFF-GRID
SOLAR PV SYSTEM AND SOLAR
STREET LIGHTS
The scheme will provide off grid solar PV
system in all government offices, schools,
colleges, Panchayats, solar water heaters in
all government quarter buildings and solar
street light on tribal roads in Daman and
Diu. The outlay for the scheme till FY 19 is
Rs 8.00 Crore.
INSTALLATION OF SOLAR PV-
LIGHTING SYSTEM IN PUBLIC
PLACES
The purpose of the scheme is to reduce
electricity bill of government installations
and to popularize non-conventional energy.
The scheme would cost Rs 2.00 Crore by FY
19.
Accordingly, the proposed capacity addition
in Renewable Initiatives is summarized

Daman & Diu has not designated any
separate agency as State Designated Agency
(SDA) of Bureau of Energy Efficiency (BEE)
and Executive Engineer of ED-DD acts as
state designated agency. The various energy
efficiency activities initiated under BEE
across UT of Daman & Diu is given in below
table:
SCHEMES FOR USAGE OF ENERGY
EFFICIENT LED BULBS AS
ILLUMINATING SOURCES
ED-DD has also taken initiative for
providing LED as a scheme for Energy
Efficiency. The following activities have
been carried out as a part of this initiative:-
1. A pilot project was taken up under BEE
program and 180 Nos. of main road
street light are converted to LED street
light
2. 280 Nos. of street light on major road
are converted to LED in Diu District.
3. Public Works Department is requested
to provide LED lights in all new Govt.
Buildings and convert the existing
lights into LED lights.
4. LED Street Lights will be provided in
Adarsh Gram.
5. 160 Nos. of LED Street lights are
provided/ converted under Tribal Sub-
Plan.
6. Replacement of conventional
domestic bulb with LED bulb under
Domestic Efficient Lighting Programme
(DELP)
7. Replacement of conventional street
lights with LED street lights under

EESL’S NATIONAL LEVEL LED
PROGRAMME
Domestic Efficient Lighting Programme
(DELP): The service model enables
domestic households to procure LED lights
at an affordable price of Rs. 10 each and the
balance on easy instalment from their
electricity bill. DELP is under
implementation in AP, Delhi, Rajasthan, UP,
Himachal Pradesh, Maharashtra. EESL is
providing to consumers at a rate of Rs. 10
each as against their market price of Rs.
200-350. The average cost saving per LED
for a domestic consumer is estimated
between Rs. 160 – Rs. 400 (depending upon
replacement of CFL or ordinary bulb) based

on 4 hour use every day is more than the
total cost of LED bulb. The total cost
charged to consumers by EESL is Rs. 95-105
(based of applicable VAT/Octroi in a state)
and is less than the savings of 1 year. The
bulb will function for at least 10-15 years
and all savings after one year is of the
consumer. The cost of LED bulbs and
programme administration cost is
recovered from consumers by deduction of
easy instalments of Rs. 10 every month for
8-12 months from their electricity bills. The
programme is delivering energy savings of
400 m kWh in Puducherry and AP as per
the online monitoring system installed by
EESL. So far more than 106 Lakh LED bulbs
have been distributed in 22 cities across
India.
Street Light National Programme (SLNP):
EESL has evolved a service model to enable
Municipalities to replace conventional lights
with LEDs at no upfront cost. The balance
cost is recovered through the municipalities
by monetizing the energy savings. EESL has
implemented about 92,000 street light
retrofit project in Vizag this project will
reduce the energy consumption by 50%.
The entire upfront capital of Rs. 64 crore
has been invested by EESL and will be
recovered over a 7 year period. The
municipality will pay EESL a sum of Rs. 18.5
crore every year whereas its overall costs
savings would be Rs. 31 crore annually. The
actual energy saving achieved 50% in
electricity bill of Greater Vizag Municipal
Corporation (GVMC) during January to April
this year as compared to same period last
year. More than 2.3 Lakh LED Street Lights
have been installed so far across India.
Replacement work of conventional Street
light with LED Street light is completed in 8
ULBs in Rajasthan, Tripura, AP &
installation work is under progress in about
90 ULBs.
ACTION POINTS FOR UT
The UT will actively associate with EESL for
launching the DELP program in UT and
would associate EESL for replacement of
street lights with LED lights.
UT would co-ordinate with BEE to conduct
a load research study with a view to
improve load factor and to reduce energy
demand by promoting energy efficiency.
The UT has 90% Industrial Sales and hence
improvement brought by energy efficiency
in other categories would be negligible.
Hence major focus of the study would be
industrial load. However, the identified
industries may participate in PAT scheme of
BEE.

CHAPTER 10: FINANCIAL VIABILITY OF
DISTRIBUTION COMPANY
FINANCIAL POSITION OF
DISTRIBUTION UTILITIES
The existing accumulated profit for ED-DD
as per the audited financial accounts of FY
14 stands at Rs. 127.19 Crores, which has
increased to 173 Crores in FY 15 (unaudited
figures). .
The existing Profit and Loss statement of
the ED-DD for FY 15 is given below:
Table 22: Profit and Loss Statement of the
ED-DD – FY 15 (In Rs Crores)
Particulars FY 15
Opening Accumulated profit ₹ 127.19 Income Income from Sale of Power ₹ 801 Other Income ₹ 7.74 Total Income ₹ 809 Expenditure Transmission Charges ₹ 75 Power & Fuel Cost ₹ 632 Employee Cost ₹ 10 R&M cost ₹ 15 A&G Expenses ₹ 6.44 Total Expenses ₹ 739 Operating Profit ₹ 69 PBDIT ₹ 69 Interest ₹ 5 PBDT ₹ 64 Depreciation ₹ 18
Prior Period and Exceptional Items
Particulars FY 15 Profit Before Tax ₹ 46 Provision for bad and doubtful debts ₹ 0 PBT (Post bad and doubtful debts) ₹ 46 Reported Net + Profit /- Loss ₹ 46 Accumulated Losses ₹ 173
FUTURE COURSE
Power Purchase expense (including
transmission cost) constitutes Rs 707 Crore
out of total Rs 739 Crore operational
expenditure and Rs 763 Crore total
expenditure of ED-DD including interest,
depreciation, taxes and other items. Since
power purchase cost constitutes 92% of
total expense of the utility therefore if
future increase in power purchase
expenditure is allowed as pass-through in
tariff by JERC the utility will be in a position
to repeat the financial performance it has
clocked in FY 15.
Capital Expenditure for proposed work
would also be incurred through budgetary
support of central government and the
utility already has cash (and equivalent) of
Rs 48 Crore. Hence the utility is also
comfortably placed in terms of cash flow for
financing future projects.
24X7 POWER FOR ALL (DAMAN & DIU) 28
CHAPTER 11: OTHER INITIATIVES
Successful implementation of 24x7 Power
Supply Scheme requires clear
communication among all the stakeholders
across the value chain, including the
consumers. In order to avoid potential
roadblocks in implementation due to poor
communication and flow of information, the
following table lists the primary
responsibility of each stakeholder and the
corresponding method in which it will be
carried out.
A centralized corporate communication
team can be formed at headquarters of the
ED-DD for looking at activities of overall
communication strategy.
To solicit consumer cooperation, ED-DD
should clearly communicate its plans on
implementing the reliable 24x7 supply
scheme along with the other reliability and
efficiency improvement measures that it are
implementing. A high level of involvement
of the Administration of Daman & Diu will
also be required:

INFORMATION TECHNOLOGY
The need to adopt IT in every sphere of
utility operation is self-evident. Power is a
complex product that must be consumed on
a real time basis. The overall value involved
in the process is very high. Even more
importantly it touches all citizens. Yet, the
information systems that drive the
operations of the sector are generally very
basic and information transparency and
consistency is poor.
Presently ED-DD has adopted steps to use
IT for improving customer service. The
department has launched mobile
application for bill payment, viewing energy
bills and previous transactions. Consumer-
Id of consumer has been mapped with his
mobile number/email-id. Applicant can also
apply for connection on-line and track the
progress of his application. Consumer can
also register his complaint on-line and track
the status of his complaint.
While sporadic efforts have been made in
the past to improve this, quantum changes
are required to increase IT adoption in all
spheres of power sector operation.
Power procurement planning and
optimization tools will be implemented
to reduce the power procurement costs
and improve supply reliability. This will
be achieved through the institution of
technically robust forecasting,
scheduling and dispatch (Unit
24X7 POWER FOR ALL (DAMAN & DIU) 29
Commitment) and settlement tools. The
tools shall be used to ensure that the
control room operators have the ability
to take real time decisions to ensure cost
reduction.
Implementation of Enterprise
Resource Planning Systems (ERP) which
would cover critical aspects like Finance
and Accounts, Asset Management,
Inventory Management, Human
Resource Management, Project
Management, Personal information
System (PIS). ERP will help in timely
capitalization of asset, deriving better
business value of investment etc.
In order to curb the
malpractices being done at the level of
meter readers while entering the meter
reading of the consumers, “Mobile
Based Photo Meter Reading & Billing
System” may be adopted.
Centralized Information & Monitoring
System for operational, enforcement &
litigation, vigilance activities and
analysis have to be operationalized.
Power management would require tools
like SCADA and Distribution
Management Systems (DMS) that allow
for adequate visualization of the
networks and response capabilities.
Technologies for sub-station automation,
GIS, SCADA, DMS, OMS, etc., shall be
adopted. For the urban areas SCADA is
very useful for improving reliability and
reduction of network downtime.
Project monitoring tools shall be
incorporated in the PMU to ensure that
progress on the investments in the UT
are monitored rigorously and
bottlenecks identified.
Standards of service specified under
Section 57 of the Electricity Act 2003 will
be monitored. The utilities shall use IT
tools to gather the information with
regard to service standards with
minimal manual.
The above measures, need to be
implemented on priority basis by ED-DD
and also to be integrated with each other to
ensure that the systems are inter-operable
(i.e., they can talk to each other). For this
the utilities shall evolve a detailed IT plan to
implement the above in a well-coordinated
manner.
ED-DD can also implement smart grid
project for the UT covering implementation
of AMI, DTMU, Integration of roof top solar
through net metering and Sub-station
automation system. The following areas can
be improved using Smart Grid technologies:
Online visualization of energy
consumption upto consumer level
Improvement in Billing Process
including correct recording of meters
and timely raising of bills
Continuous two way communication
facility between utility and consumers
and empowering consumers to
participate in Energy Management
Process
Monitoring of Outage & Quality of power
upto consumer level
Online information for utilization of
assets like distribution transformer, LT
lines etc.
Preventive maintenance of distribution
transformer
Control and monitoring of sub-station
equipment
Utilization of renewable resources
towards sustainability & green energy
benefits by net metering

INSTITUTIONAL ARRANGEMENT
A strong monitoring framework is essential
to ensure the success of the “Power for All”
scheme. The following structure is being
proposed to undertake regular monitoring
of the progress of all initiatives being
undertaken in this scheme.
Government of India (GOI) Level
Committee: It is proposed that this
committee will review the overall
progress of the scheme on a quarterly
basis and provide necessary support to
ensure a coordinated response from
the Central Government - where
necessary. The committee may be
constituted with the following
members – PFC, REC, CEA, SECI, EESL,
BEE, Ministry of Power, MoEF and
MNRE.
UT administration Level Committee:
It is proposed that a UT level
committee headed by the Secretary
(Power) will be formed to review the
progress of the scheme on a quarterly
basis. This committee will monitor the
progress of the works undertaken as
part of the scheme and issue directions
to enable faster execution.
Department Level Committee: It is
proposed that a Department level
committee headed by the Nodal Officer
will be formed which shall undertake
steps required to ensure the projects
are progressing as per the action plan.
This committee will undertake
progress reviews on a monthly basis.
District Level Committee – It is
proposed to constitute a district level
committee headed by the A.E. to take
action that is necessary to ensure the
projects are completed in a timely
manner and address any issues
pertaining to land or other relevant
approvals.
Project Monitoring Unit (PMU) – A
project monitoring unit shall be set up
for monitoring the progress of the
works being undertaken under this
scheme. The PMU will operate under
the Secretary, Power and shall be
operated by an external independent
agency.
The PMU shall be responsible for
undertaking coordination, preparing
the action plans and monitoring
progress of all works under the “Power
for all” scheme. The PMU would also
help facilitate in tracking the action
steps and providing feedback to the
various committee that are proposed to
be set up under the scheme.
Government of India shall provide
grants for the PMU operations.
The committees that are being proposed
above are required to be set up at the
earliest to kick start the whole scheme. It is
important that the committees keep
meeting on a regular basis as per the
frequency/ timelines mentioned above – to
ensure that the objectives set out under the
“Power for all” scheme are achieved.
CAPACITY BUILDING
With the increase of IT applications in the
Transmission & Distribution system and to
meet the expectations of 24x7 power supply
for the consumers in the UT, it is important
to focus on capacity building of the
employees for enhancement of technical
know-how and keeping abreast with latest
technological developments. The capacity
building may also include consumer
grievance system, awareness regarding
importance of working with safety, outage
management system, demand side
management etc. It is also imperative that
for transforming the distribution utility into
24X7 POWER FOR ALL (DAMAN & DIU) 31
a customer friendly one, change of mind-set
of the employees would be required. It is
critical that Change Management initiatives
are rolled out and institutionalized for
achieving better results.
In view of the importance of training on
new technologies, there is a requirement for
development and implementation of a well-
structured Human Resource Training
Programme to help realize the dream of
24x7 power supply system in the UT in its
true sense.
There is already a provision for Demand
Side Management (DMS) training under
various programmes of Bureau of energy
Efficiency (BEE) and the same should be
implemented to achieve the goal of 24 x 7
power.
A UT level officers training institute may be
required to be opened in the UT to fulfil the
ongoing training requirement for
employees of ED-DD. This also helps in
training of subordinate technical staff.
Following training programmes are
proposed to be implemented for the utility:
Two Weeks trainings for technical staff
including officers & engineers once in
every two years.
One week training for non-technical
officers every two years.
One week training for subordinate
technical staff at each district
headquarters every year.

CHAPTER 12: YEAR WISE ROLL OUT PLAN
SWOT ANALYSIS
In the above sections we have discussed in detail the existing status and its future needs. We
have also provided some actionable targets which will help Daman & Diu in achieving the set
goal. Before structuring the above targets, SWOT analysis of existing power sector in Daman &
Diu has been discussed. The exercise has been done to bring out some of the key risk indicators
which affect the overall market in Daman & Diu along with advantages present.
From the above analysis it is quite evident that most of the threats are external factors which
would need continuous efforts from Daman & Diu to mitigate them as soon as possible. Further,
from the weaknesses tabulated it is seen that, with some strong and bold measures Daman &
Diu will be able to attain the target.
Based on the above observations, a road map for Daman & Diu has been developed to mitigate
the above weaknesses and threats.
