EPC Companies Are Facing Several Challenges
Issues
With
Solar EPC
Companies
Solar technology is not considered for project finance
funding – Substantial fund requirement with limited
banking facility
Competitive bidding drove prices for grid-connected
solar energy to INR7.49 – Race for cost reduction has
led to compromise in quality
New technology – Shortage of skilled manpower
Financial closure, land procurement and
development reduces project execution time –
Compromising quality
Grid connectivity is delayed sometimes by as
long as 12 months in certain cases – losses for

Opportunities
• As per an October 2012 report, the Indian Ministry of Commerce have said that the Indian solar
manufactures have called for anti-dumping duties as high as 200%
• The Ministry of New and Renewable Energy is likely to strengthen the current Domestic Content
Requirement in the upcoming phase two of the NSM
• By 2022, India will need INR1.6 trillion worth solar modules at today's prices

been in the industry
for decades
Very difficult to
compete with such
existing players in
terms of technology
as well as cost
Balance of Systems
Used to account for only 10-
15% of the total cost
With recent decline in other
cost components BoS

Does not make much sense in
investing resources in this
activity as components are
diverse (civil

Threat from local module manufacturers entering EPC space
• Vikram Solar – Projects pipeline of 40MW for module supply and EPC under batch two of phase
one of the NSM and the Gujarat Solar Policy.
• Lanco Solar – Providing EPC for Gas Authority of India Ltd. (GAIL), is expected to use its own
modules.
• Enfield Infra-structure is developing a 10MW project under the batch two of phase one of the
NSM and is expected to use its own modules that are being manufactured under the name of

Key Challenges with respect to Indian Market :
CEPC for Renewable Energy Certificates
Penalties
imposed on
States for not
complying with
obligated RPO’s
Bankability of
products
without PPA in
question
IPP’s might
start late when
project costs
are dropped or
technology
improved
For a Market
driven
phenomenon
feasibility is
difficult to
access.
In case of non-
compliance the utilities
will be imposed a
penalty equivalent to
the forbearance price
multiplied by the
shortfall in RPO
compliance. Hence, the
state agencies will
comply with obligated
RPO’s
The prices are still
regulated between a
floor and a forbearance
price which has been
done to ensure the
minimum feasibility of
the project and
simultaneously giving
room for profit making
A lot of incentives are
offered to early starters
like higher floor and
forbearance
prices, allowing
Accelerated
Depreciation
benefit, assuming a
higher project
cost, excise duty
off, custom duty off etc.
These incentives will
not be available to the
next phase developers.
This issue has been
addressed by limiting
the number of PPA’s
that the government
will sign with the
Project developers and
moreover all PPA’s will
be through the bidding
route thus minimizing
any extra incentive.
REC has been successful in other countries like UK, Australia, USA etc.

Surmounting The Challenges
LAND AVAILABILITY

GRID
WATER AVAILABILITY
ISSUE
GAS, SEWERAGE, ROADS
AND FENCING
Existence of suitable land not a barrier
“As per Status report (Arora et al, 2010), the land area with DNI greater than
2,000 kWh/m2/year in India is around 112,500 km2. This is sufficient for a
generating potential of about 10,930 TWh per year, many times the total
electricity consumption projected for the country. Thus the existence of
suitable land per se is not a barrier.”
Solar Park concept vindicated
The Indian HV transmission network is extensive. However, the 11kV
distribution system is limited. HV transmission is a mixture of
400kV, 132kV and 33kV, substations drop this to 11kV for the
distribution system. As a substation is expensive, it needs a large load to
justify the investment.
Solar Parks more cost effective towards following:
• potential limited physical availability of water,
• approvals process for accessing water supplies, and
• cost of supply infrastructure.
Dependent upon the technology type being used

Diversification In Emerging Markets: Why The Conventional
Definition And Strategy May Not Be Applicable
Diversification In Emerging
Markets
In developed markets, unrelated
diversification is thought to be
value destroying
Diversification in
Developed Markets
Emerging markets have different
dynamics as compared to
developed markets and thus
diversification and synergy have
different connotations
Diversification is justified if
• The company is the best owner of the business
• There is a synergy between existing and new
businesses
Diversification is justified because
• Large conglomerates typically have the resources and
relationships needed to navigate the maze of
government regulations
• Large conglomerates are more attractive to potential
managers because they offer greater career
development opportunities
• Large conglomerates have economic benefits that don’t
exist in the developed world, especially in infra sector
Source: McKinsey on Finance Number 42, Winter 2012
The diversification decision should not be based on the synergies only. Mahindra
EPC can diversify based on the opportunities available

Gujarat Case Study
• 963MW of solar PPAs had been executed but only 175 MW could meet the deadline of Dec
31, 2011 for achieving COD
• 128 MW awaiting transmission connectivity – no deemed generation in PPAs
• Also failed to forecast volatility of solar panel prices
Lost Opportunity:
Risks that were ignored or not
appreciated:
• Failure to achieve financial closure
• Logistics issues were not appreciated -
land aggregation and transmission
• Completely overlooked the significant
financial impact on retail tariffs
EPC Risks identified:
• Land aggregation
• R&R and local community sensitivities
• Land registration and conversion
• Financing
• Technology and Execution risks were minimal

Abstract: The paper summarizes the efforts of an elective design studio in which a parametric model was linked to
detailed energy output data in order to provide accurate feedback about building performance
throughout the entire process of design. Photovoltaic collection data was downloaded from the National
Renewable Energy Laboratories (NREL) and linked directly to alternative configurations of designs
produced in SolidWorks. Microsoft Excel provided the direct link between the model and data where
students were able to augment the SolidWorks Excel output to include calculations that referenced the
NREL data. The program from the 2009 Solar Decathlon competition served as the program for the
investigation and provided a constraint-rich environment for developing parametric models. The class
also utilized morphological analysis to identify 13 different forms to develop and analyze. The resulting
parametric models and analysis provided a focused introduction to design methods, parametric
modeling and solar energy design.
Keywords: Parametric model, PVWATTS calculator, SolidWorks Excel output, building performance.

Other Recommendations
• Mahindra EPC can tie up with foreign companies to acquire new technologies and
build competencies in the domestic market
• Mahindra EPC can experiment with new BoS in initial years. Role of BoS can be a
crucial one for plant efficiency
• Mahindra EPC can also look for EPC opportunities abroad to develop a comprehensive
domestic strategy with learnings from foreign exposure.
• Mahindra EPC can experiment with the best EPC models prevailing globally –
LSTK, BoS-EPC, etc. – to finalize upon the best EPC model for India.
