1. Background
Madhya Pradesh has fostered industrialization in the state, whereby the Government of Madhya
Pradesh (GoMP) has provided necessary support, be it in the form of developing infrastructure
or formulating industry-friendly policies. This was the sole reason for the birth of Madhya Pradesh
Audyogik Kendra Vikas Nigam Ltd (MPAKVN) - a synonym to growth in the state.
Established in the early 80s, MPIDC (erstwhile MPAKVN) is a wholly owned undertaking of
GoMP with a sole vision to establish Western Madhya Pradesh as an industrious economy.
MPIDC (Indore), since its inception has taken major initiatives for promoting industrialization in
the state, including identifying
growth centers, setting up,
promoting, and nurturing these
industrial hubs and above all
inviting investors.
It has been instrumental in
establishing Industrial Growth
Centers at Pithampur, Kheda,
Maksi, Dewas, Meghnagar, etc.
in addition to other commercial
zones like Food Parks,
Readymade Garment Complex,
etc. across Western MP. Its latest
project, Crystal IT Park, is a
promising initiative that may
open floodgates in M.P. to a
whole new world of opportunity
and enterprise.
MPIDC (I) as a distribution licensee
For supporting growth in industrialization, MPIDC Indore, was notified as the developer of
Special Economic Zone (hereinafter referred to as ’SEZ’) at Pithampur, near to Indore, prior to the
enactment of SEZ Act, 2005 which became operational w.e.f. 15.08.2003. This SEZ is a green field
multi-product SEZ of India and is spread over an area of more than 1100 hectares of land in Zones,
SEZ - I & II. Industries of various sectors such as Plastic, Engineering, Pharmaceutical, Metal,
Textile & Food processing etc. are in the Zone.
Central Government vide its notification dated 3rdMarch 2010, amended Section 14 of the
Electricity Act, 2003(hereinafter referred to as ‘Act’), wherein, the developer of SEZs have been
deemed to be a Distribution Licensee (hereinafter referred to as “Licensee”). MPIDC (I), being the
Technical Report on CAPEX for 63 MVA transformer of MPIDC
4 | P a g e
developer of SEZ, is responsible for provision of utility services which also includes supply of
electricity within the SEZ area to its consumers. As per the said amendment, MPIDC (I) being the
developer of SEZ, filed a petition at Hon’ble Madhya Pradesh Electricity Regulatory Commission
(MPERC) for taking on record its status as a Deemed Distribution Licensee and seeking specific
conditions of Distribution License, for providing benefits to its consumers w.r.t providing cost
effective and uninterrupted electricity. Hon’ble MPERC subsequently granted the same in 2005
to MPIDC (I).
2. History of Supply Business
MPIDC started its power supply business in SEZ area as a distribution licensee from 13.03.2005,
with only four (4) consumers in its area which increased substantially as the years passed by. The
initial contracted demand of the SEZ area (for SEZ – I & II both combining) was 10 MW which
gradually increased to 18 MW during the FY 2013-14 due to increase in number of consumers.
During the FY 2016-17, the total contracted demand of SEZ area was increased to 40 MW due to
rising number of consumers. The demand was further increased to 50 MW during the FY 2019-
20 (presently the contracted demand is 55 MW).
Due to increase in the number of new consumers, it is imperative for MPIDC (I) to augment its
existing facility at higher voltage level to meet the existing and future demand. Further to add, a
good amount of undeveloped area (~40%), available inside the SEZ – II area, was almost sold to
various industrial consumers after its development. A comparison of consumers’ vis-à-vis total
energy sales in SEZ area is shown as below:
Figure 1: Number of Consumers and Total Energy Sales in SEZ Area.
MPIDC (I) took an initiative of providing electricity supply to its SEZ consumers with an objective
of providing quality and reliable power with minimum number of tripping ensuring cost
optimization to its consumers, both in terms of reducing electricity procurement costs as well as

boosting manufacturing efficiency (being most of the industries are manufacturing units) by
providing quality supply.
For meeting the power requirement of the SEZ area, MPIDC (I) had signed a Bulk Power
Transmission Agreement (BPTA) with erstwhile Madhya Pradesh State Electricity Board
(MPSEB) (a body constituted under the Electricity (Supply) Act, 1948 – predecessor entity of MP
Power Transmission Company Ltd) on 29.01.2005.
With increase in number of consumers and subsequently their power requirement, as also
mentioned in previous section, the original BPTA got supplemented five times on 11.10.2010,
05.10.2013, 29.03.2016, 15.04.2018 and 29.08.2018 for enhancement of the existing Contracted
Capacity to 50MW.
As explicitly provided above, it was imperative on account on MPIDC (I), as a contractual
obligation, to construct a 132/33 kV sub-station for increasing its contracted demand to serve its
consumers.
The overall SEZ area is categorized into two (2) different zones i.e. SEZ – I &SEZ – II. The contract
demand of these zones, as on 01.04.2016, was15 MW and 25 MW respectively. The power to both
these areas of SEZ was being supplied from three bays (10 MW each capacity, i.e. 30 MW in total)
of 220 kV MPPTCL sub-station.
After the development of extra space available inside the SEZ – II area, more industrial consumers
were added in the same due to which requirement of power has been also increased. The
anticipated demand in the SEZ area (both SEZ-I and SEZ-II combining) is expected to reach 87
MW. For serving the increased/ future demand, it became imperative for MPIDC (I) to construct
a dedicated 132 kV sub-station inside the SEZ-II area.
The 220 kV transmission sub-station, as mentioned above, is near SEZ-I area, whereas it is far (>3
kms) from the SEZ-II area (where extra space is available and demand is being increased).
Considering higher transmission losses (~2%), in transmitting power at higher distances, and
quality of supply, a dedicated sub-station inside the SEZ area was constructed. Also, it was
observed that construction of 132 kV Sub-Station was cost effective with respect to 220 kV sub-
station.
At present, the total cumulative demand of SEZ area is 70 MW i.e., SEZ – I is having a total
demand of 15 MW and SEZ – II is having a total demand of 55 MW. The power supply is being
fed through 220 kV sub-station of MPPTCL to SEZ – I area and through dedicated 132 kV sub-
station to SEZ –II area. As also mentioned above, after the allocation of the hilly land, which is
presently undeveloped, available in SEZ-II area, new consumers are being getting added and
Technical Report on CAPEX for 63 MVA transformer of MPIDC

demand is being increased. Presently the demand of the SEZ-II area is ~55 MW, and the same is
expected to increase to 72 MW in near future. With the construction of 132/33 kV sub-station in
SEZ-II area, a total of ~50 MW was easily catered in the SEZ-II area (presently demand in SEZ-II
area is ~55 MW). Considering future projected cumulative load of 87 MW (both SEZ I and SEZ
II), further network upgradation will be required.
Construction of a dedicated 132/33 kV sub-station was taken up in June 2017 by MPIDC (I) in
SEZ-II area on post facto approval by Hon’ble State Commission. The construction of same was
accomplished in-line with the agreement as well as with the objective of meeting future demand
and attracting more consumers to the SEZ ensuring higher revenue to the state.
Additional benefits achieved with the construction of new 132/33 kV sub-station for MPIDC are
as follows:
System strengthening and creation of infrastructure in undeveloped area
Reduced Technical and Commercial losses
Improved reliability of supply
Improvement in quality of power supplied to the industries situated in the SEZ area.
MPIDC completed construction of 132/33 kV substation considering the incoming power at 132
kV and transfer of power to main bus through isolator-circuit breaker-isolator combination. The
power from main bus is fed into a 63 MVA transformer which stepped down to 33 kV. The power
is then fed into a 33 KV bus from which different loads are tapped. Starting from the generating
stations to the end users, voltage was needed to be stepped up and down several times in
substations which ensures efficient transmission of power and minimizing the power losses. The
entire load of SEZ-II area which is around 55MW is catered through 132/33 kV substation and by
single 63 MVA transformer.
Construction of 132/33 kV sub-station instead of constructing a 220 kV sub-station, was a major
decision taken by MPIDC to achieve cost optimization and not burdening the consumers with
additional costs.

3. Requirement of an additional 63 MVA
Transformer in SEZ-II
Special Economic Zone (SEZ) is an area in which business and trade laws are different from the
rest of the country. SEZs main aim is to increase trade balance, investment, and effective
administration in the area. Following a similar objective, MPIDC has recently developed the hilly
(elevated) area available inside the SEZ-II premises which is attributable to more industrial
consumers being added in SEZ-II area, with which the power requirement is expected to increase
exponentially and reach ~70 MW.
As per the regulations “The Conditions of Distribution License for Distribution Licensee, 2004”
issued by Hon’ble Commission it is stated that,
“9.9 …….The Licensee shall submit a 5-year Business Plan within three months from the date of
effectiveness of the Transfer Scheme and updated annually which should contain year wise load growth,
…year wise distribution loss reduction proposal…….”
“21..2 ……The Licensee shall plan and operate its Distribution System to ensure that, subject to the
availability of adequate power of appropriate quality, the system is capable of providing consumers
with a safe, reliable and efficient supply of electricity…….
It is observed that the load of SEZ-II has been increased to 55 MW in Oct-20 along with an increase
in number of consumers to 50. Further, considering the expansion planned for undeveloped area,
i.e., hilly area, inside SEZ-II, the estimated load will reach ~70 MW, which will further impact the
loading levels of transformer and supply redundancy.
As the SEZ area is occupied by the industrial consumers for which continuous, reliable, and
efficient supply of electricity is the foremost requirement, therefore it becomes the prime objective
of MPIDC, being a distribution licensee, to fulfill the requirements of the industrial consumers
and provide low-priced, uninterrupted, and quality power.
Generally, the optimum loading levels of transformer are considered at 80% - 85% and loading of
transformer beyond such levels may harm the transformer winding, insulation level and their
efficiency in the long run. As per the present scenario the current transformer loading in SEZ-II
area has been observed at ~80-85% in recent months and is further expected to increase with
increase in the number of consumers in the newly developed area by MPIDC, which could impact
the transformer efficiency levels with increase in Iron loss, Hysteresis loss, Copper loss, Eddy
Current Loss etc., further impacting the life of transformer, and power quality for the consumers.

Technical Report on CAPEX for 63 MVA transformer of MPIDC
11 | P a g e
As per the regulations “The Conditions of distribution license for distribution licensee, 2004”
issued by Hon’ble Commission it is also stated that,
10.3…..The Licensee shall make an application to the Commission for obtaining prior approval of the
Commission for schemes involving investments………….
a. ……there is a need for the investment in the Distribution System b. …the Licensee has examined the economic, technical, system and environmental aspects of all
viable alternatives to the proposal…….
Considering the aforesaid regulation and examining the technical requirement with respect to
load growth inside the SEZ-II area, it is imperative on account of MPIDC to install a new
additional transformer of 63 MVA inside the 132/33kV substation to maintain the load balance
inside SEZ and to supply reliable, efficient, and quality power to its consumers.
A small study for impact of overloading of transformers is provided below for reference:
The power transformer is one of the most
expensive components in an electrical
transmission and distribution network. The
temperature inside a power transformer
varies with the load. When load is increased
the windings heat up and then cool down
again when it is decreased. In our case, due
to presence of Industrial consumers, the
load may not come down for some days. So,
it may burst when either the load is
extremely high for a short period or high
loading over a long period of time. In short,
overloading reduces the life of a transformer. Higher current in transformer windings, increases
copper loss in transformer which dissipate energy in the form of heat. This may cause transformer
to exceed its safe temperature limits if transformer is overloaded beyond its design limits.
Overloading is still the most common reason for transformer failure in India. In some utilities,
the annual failure rate for transformers is as high as 20 percent and above.

4. Proposal by MPIDC
MPIDC started its power supply business in SEZ area as a distribution licensee from 13.03.2005,
with only four (4) consumers in its area which increased substantially as the years passed with 50
consumers as if now. For supporting growth in industrialization, MPIDC has always ensured to
provide good quality of supply to industrial consumers, with minimum losses, with minimum
tripping as well as MPIDC always operates as per the regulations issued by Hon’ble Commission.
As mentioned in previous sections, due to increase in number of consumers in the newly built-
up area, sales and connected load in the SEZ-II area has increased along with that the loading
levels on transformer has increased and reached to a level of 80-85%, which is expected to increase
further with anticipated increase in load. Considering the same and with an objective to maintain
supply redundancy as per the MPERC regulation (The Conditions of distribution license for
distribution licensee (including deemed licensee), 2004, it is proposed to install an additional 63
MVA transformer in 132/33 kV sub-station switchyard. The bays for the proposed installation
are already available in sub-station.
Benefits of an additional transformer
Stabilize the loading levels on power transformer.
During maintenance work, load may be transferred to one of the transformers and another
can be repaired/serviced hassle free, which will ultimately benefit in supplying
uninterrupted power to Industries.
It will enable MPIDC to bifurcate loads among two transformers which will lower the risk
of transformer failure.
Reduction of electricity losses in electrical transformers.
Improving the power quality due to stable level of short circuit current in the network.

Load of SEZ-II area is expected to reach more than 70 MW and considering the aforesaid scenario
additional 63 MVA transformer can cater an additional load of 45.36 MW, considering power
factor of 0.9 and load factor of 0.8. This will assist MPIDC to cater load of more than 70 MW, by
balancing total load on both the transformer resulting in higher efficiency and lesser losses.
During any technical fault or preventive maintenance period, the additional transformer of 63
MVA will act as backup/stand-by transformer help in balancing the entire load of SEZ-II area,
which will further assist MPIDC in uninterrupted power flow to the industries.
Considering this scenario additional 63 MVA transformer will be an appropriate option to cater
the continuous increasing load and maintain consumer satisfaction.

5. Estimated Cost Break up of 63 MVA transformer
At present, load on single Transformer having capacity of 63 MVA has increased around 50 MVA
(in Oct 2020), due to growth in the connected number of industries. In view to meet the load
growth and maintain network redundancy, it becomes necessity to install additional 63 MVA
transformer in 132/33 kV switchyard. The present infrastructure inside the substation also
supports addition of another transformer as it has sufficient land space and bays.
For the installation of new 63 MVA transformer in 132/33 kV sub-station switchyard at SEZ-II,
the estimated cost break-up amounting to Rs. 886.74 lacs is as mentioned below:

be installed in the SEZ – II premises, along with its estimated cost break up.
Further in this section, payback period for additional 63 MVA transformer has also been
computed on certain assumptions. As could be inferred from above, equity to be infused by
MPIDC is ~Rs. 8.87 Crs. for installing the above said transformer.
In this section, a comprehensive cost benefit analysis is presented for the expenditure to be
incurred for the installation of 63 MVA transformer in the existing 132/33 kV sub-station switch
yard. Also, for the purpose of capital budgeting techniques, financial estimations consisting of
NPV, IRR and payback period has been computed for the entire project cost in the next section.
For computations, certain assumptions have been considered which are as below:
6.1 Base Assumptions

6.2 Benefits under setting up new transformer in 132/33 kV sub-station
Increase in Energy Sales: Due to installation of 63 MVA transformer, MPIDC will be able
to draw and sell more power resulting in increased energy sales and additional revenue
generation.
Loss Reduction: As mentioned above, losses are expected to be reduced after the
installation of an additional transformer. For computation, the distribution losses
gradually are assumed to decrease by 0.05% every year till the total loss level reduces by
0.25% with proportional increase in load.
Load management: By installing the additional transformer in 132/33 kV Substation switchyard load can be balanced on the power transformers which will help transformers in preventing internal damages occurred due to overloading which will further reduce the irregular tripping in the SEZ area.
6.3 Revenue generation
The calculation of the payback period has been segregated in two components.
a. Additional revenue generation due to increase in energy sales after the installation of the
63 MVA transformer.
b. Reduction in distribution losses after the installation 63 MVA transformer in the 132/33
kV sub-station.
For computing additional revenue generation and reduction in distribution losses, the following
analysis has been done:

7. Evaluation method for financial Estimations
To evaluate the capital expenditure done towards the installation of 63 MVA additional
transformer, the following capital budgeting techniques are computed in this section:
The above-mentioned budgeting techniques are used on the total investment made, i.e. Grant +
Equity, for the installation of 63 MVA additional transformer.
7.1 NPV Method
Net present value method (also known as discounted cash flow method) is a popular capital
budgeting technique that considers the time value of money. It uses net present value of the
investment project as the base to accept or reject a proposed investment in projects like purchase
of new equipment, purchase of inventory, expansion or addition of existing plant assets and the
installation of new plants etc.Net present value is the difference between the present value of cash
inflows and the present value of cash outflows that occur as a result of undertaking an investment
project. It may be positive, zero or negative. These three possibilities of net present value are
briefly explained below:
NPV for the total project investment for installing up of the additional transformer of 63 MVA
in 132/33 kV sub-station is represented below
Net present value (NPV)
Internal rate of return (IRR)
Payback period (PP)
Positive NPV
•If present value of cash inflows is greater than the present value of the cash outflows, the net present value is said to be positive and the investment proposal is considered to be acceptable
Zero NPV•If present value of cash inflow is equal to present value of cash outflow, the net present value is said to be zero and the investment proposal is considered to be acceptable
Negative NPV•If present value of cash inflow is less than present value of cash outflow, the net present value is said to be negative and the investment proposal is rejected

As we can see from above computation, NPV comes out to be 49.29 Cr. Thus, as per NPV Method
installation of another transformer is preferred.
7.2 IRR Method
Internal rate of return (IRR) is a metric used in capital budgeting to estimate the profitability of
potential investments. Internal rate of return is a discount rate that makes the net present value
(NPV) of all cash flows from a particular project equal to zero.
The higher a project's internal rate of return, the more desirable it is to undertake. IRR is uniform
for investments of varying types and, as such, IRR can be used to rank multiple prospective
projects on a relatively even basis. Assuming the costs of investment are equal among the various
projects, the project with the highest IRR would probably be considered the best and be
undertaken first.

station is represented below:

As we can see from above computation, IRR comes out to be 42.08%. Thus, as per IRR Method
installation of another transformer is preferred.
7.3 Payback Method
Payback period, or “payback method,” refers to the amount of time it takes to recover the cost of
an investment. Simply put, the payback period is the length of time an investment reaches a
break-even point. The desirability of an investment is related to its payback period. Shorter
paybacks mean more attractive investments. The shorter the payback, the more desirable the
investment. Conversely, the longer the payback, the less desirable it is. Investors and managers
can use the payback period to make quick judgments on their investments. The concept of the
payback period is generally used in financial and capital budgeting.

132/33 kV sub-station is represented below:

Considering the investment and benefits involved on addition of another transformer, the
payback period for the investment done will be less than 9 years. Thus, as per payback method
also, installation of new transformer is preferred.
7.4 Conclusion
Considering above mentioned capital budgeting techniques, addition of new transformer is a
viable investment decision w.r.t project economics and technical feasibility. Through NPV, IRR
and Payback method, adding a 63 MVA transformer will result in increased in Energy Sales,
reduced losses, and flexibility for load management during repair or maintenance of the network.
