Executive Summary
Energy is a necessary driver of growth and its per capita consumption is growing
all across the world. This is primarily associated with the growth and development.
Any developmental activity in a nation fuels the energy demand. The world already
realise the need to switch over Renewable Energy (RE) source to augment the energy
needs. Clean sources of energy not only help our environment to recover from the
mindless exploitation it has been subjected to in the last 150 years, but also provides
power to millions of people especially in the developing nations. The renewable energy
sector has emerged as the fastest growing industry in recent times and there are hopes
of it getting only bigger in the coming years. Most nations have put plans in motion to
promote this sector in a big way. Green growth is the way to future for the developed
nations and a huge opportunity of energy security for the developing nations. There is
one more advantage which is slowly being recognized as the most important aspect of
this change- it’s potential to create employment for millions in the coming decade. In
India, there is still a huge gap between the demand and supply of electricity. Its power
sector is consistently plagued by shortages. India currently ranks fourth in the world for
green house gas emissions. There is a need to balance the two- the growing huge energy
needs with climate change issues. That is where the renewable energy sources come
into play. The Indian government, Ministry of New & Renewable Energy (MNRE) has
various policies and plans to advance solar and other renewable energy in the country.
The support from Government is a prerequisite to push forth the emerging concept of
generation-based incentive of solar power. The incentives announced by MNRE are a
well timed policy measure, which is oriented towards a bigger role for solar power and
is based on some gainful insights into the actual operation of megawatt sizes solar
power plants.
1. Benefits of grid connected Solar Photovoltaic (SPV) System:
Power from the sun is clean, silent, limitless and free
Power production from Solar Photovoltaic process does not
releases gases like CO, CO2, SO2, NO2, which are normally
associated with burning finite fossil fuel reserves and don’t
contribute to global warming.

Solar Photovoltaic are now a proven technology which is inherently safe as
opposed to other fossil fuel based electricity generating technologies.
Reduces or avoids the necessity to build new transmission/distribution lines or
upgrade existing ones.
Solar power shall augment the needs of peak power needs.
Increases the grid reliability i.e., voltage and frequency.
Reduce the transmission line losses.
Provides a potential revenue source in a diverse energy portfolio
Assists in meeting renewable portfolio standard goals.

4. Introduction
Climate change and fossil fuel depletion are threatening our very existence on
this planet. This is primarily due to our dependence on fossil fuels for an upkeep of
modern day life styles. Nearly 75% of energy usage takes place in urban and semi-urban
areas accommodating large chunks of population. The rapid urbanization with
an accompanying economic development is responsible for a sudden rise in energy
demand. Essential public services like electricity services for homes, transport, industry,
commerce, and other infrastructure run by virtue of fossil fuels. To secure the energy
supply for all this and to mitigate the risks of climate change, RE source of energy form
the most obvious solution. With its abundant solar energy, India can exploit this
resource easily.
Most of today’s electrical energy is generated by fossil fuel based plant with a
low production cost and high reliability. However, concerns about the longer term
sustainability of fossil fuel-based generation, are driving the energy industry toward
sustainable, low carbon emitting, renewable energy sources. Indian government -
MNRE has demonstrated its commitment to the cause of promoting RE power
generation and solar in specific by its current policies.
India is a tropical country, where sunshine is available for longer hours per day
and in great intensity. It is home to one of the most abundant solar resources in the
world, with 2.97 million square kilometres of tropical and subtropical land and an
average of 300 clear sunny days a year. As such, solar power offers significant potential
to meet a large share of the country's energy needs.
Solar energy, therefore, has a tremendous potential as a future energy source. It
has the advantage of permitting decentralized distribution of energy, large, centralized
power generation plants, smaller distributed heat and power plants; or scaled down, at
the individual consumer level. Thus it has the leverage of empowering people at grass
root level.
It is not only technically and economically feasible for India to make the shift to
renewable energy sources (if this rollout is combined with energy-efficiency measures),
but also prudent to begin this transition now. The Government has recently approved
an ambitious new plan to increase solar power capacity to 20 Giga watts by 2020, under
the National Solar Mission. The Mission is to provide lighting for 20 million homes and
eliminate 42 million tons of carbon dioxide emissions annually.
There are several reasons for this urgency. First, India's power-generation
infrastructure is undergoing rapid expansion to meet national development objectives,
with the country still facing unmet power demands that equate to as much as 80 percent
of current installed capacity. Second, they point to rising energy security concerns as

energy prices go up and supplies shrink, making it a ripe time to shift to a new model of
energy production.
As on March, 2009, India’s power system had an installed generating capacity
around 1,48,700.00 MW and thermal power plants powered by coal, gas, naphtha or oil
accounted for approximately 64.70 % of total power generation capacity. Hydropower
picks up a share of 24.80%. Renewable sources of energy account for around 8% of the
power generated, with wind power having a share of around 5.5%. In the same year a
capacity addition of nearly 51,300 MW has been planned by the ministry of power
during the eleventh five year plan period (2009-2012).Thus there is a need for large scale
power generation from both Non-renewable and renewable sources of energy to sustain
a targeted GDP growth of 8%to 10% per year.
Of late, solar power investments in the country are registering a fast increase. In
fact, India is a home to many national and international PV manufacturers setting up
large scale PV manufacturing facilities. There is a growing optimism on the fact that
solar power may well attain the much needed grid parity within the next few years.
India is a developing nation and cannot halt its developmental goals. While we
have a need to cut down the GHG emissions, it also has to ensure that its infrastructural
growth is not hindered in any way. Solar energy in India is a potential huge source of
energy. If we are able to harness the high amount of sunlight received by India, then we
can meet its energy demand like no other fuel.

and has a superior holding capacity with distinct advantage in unstable soils. As with
this technology the foundation can be erected in few hrs as there is very less concrete
work and the mounting is done by the machines, implementation is swift with several
hundred foundation points being completed in a day.

A PV Array is made up of PV modules, which are environmentally sealed
collections PV cells-the devices that convert sunlight to electricity. This allows some
assembly and wirings functions to be done on the ground if called for by the installation
instructions. The panels will be mounted in rows and electrically connected with cables.

6.1.3 Inverters (CONTROL TECHNIQUES)
The grid tie inverter in a solar
PV power plant converts the DC power
generated by the PV module in to
suitable AC power for feeding to the
grid. This inverter automates the start up
and shut down functions. By
incorporating advanced maximum
power point tracking technology, it
maximizes the energy harvested for PV
modules. To minimize the power losses
during the conversion process, the inverter switching technology uses insulated gate
bipolar transistors. Multiple inverters are paralleled for large power installations. High
efficiency of conversion under partial load conditions is essential for economic viability
of the entire solar power station the inverters with their own weatherproof enclosure
installed in close proximity to PV modules are considered for this project.

(main DC combiner boxes), central inverters, low voltage panels, transformer,
high voltage panels, etc. below shown are the few reference snapshots of the
same.
 Description of power evacuation system and interfacing with grid
It is important that the power plant is designed to operate satisfactorily in
parallel with grid, under the voltage and frequency fluctuation condition, so as
to export the maximum possible unit to the grid. It is also extremely important to
safeguard the system during major disturbances like tripping, pulling and
sudden over loading during the fluctuation of the grid loads on the generating
unit in the island mode, under fault/feeder tripping conditions.
 Grid Synchronization Scheme
Utilities/license owns and operates a high voltage transmission and
distribution network in the project area. It is envisaged that the solar generation
plant will be connected to the high voltage network. It will be necessary to
negotiate a network connection and access agreement and undertake further
activities, such as:
a) System studies.
b) Investigation of connection issues including assessment of the need to upgrade
or modify equipment due to an increase in fault levels.
c) Protection modifications as compatible for system frequency and grid stability.

16
 Network Connection
The solar PV project size is proposed to be 1 MWp. The higher rating is
used for grid connection designs. The proposed plant will be connected to the
high voltage transmission system through a 0.415/11/33KV substation. This
involves an appropriate power transformer, underground cables and overhead
lines at appropriate voltage level. The network connection is designed to carry
rated power on a 24-hour basis. For connection to the state transmission grid, it is
necessary to adhere to grid code. This requires a series of studies and designs,
including:
 Load flow studies.
 Fault level analysis.
 Dynamic stability assessment.
 Connection substation concept design.
 Protection measures for connection substation and power transmission line.

(The prices are subjected to escalation starting from two years)
Performance monitoring
A plant monitoring system is installed which enables permanent system
monitoring and performance evaluation. We collect the data on site via our PV
monitoring system. This data are available for remote diagnosis and a useful subset of
the gathered performance data is made available online to the customer so that he can
track and control the system performance himself.

17
Remote diagnosis and failure response
Automatic alarm functions issue messages in case of unexpected system
behavior that will trigger the first level support to log onto the system and investigate
and initiate remedial action if required. Second and third level expert support will be
involved as required. Field service engineer are dispatched as needed in order to clarify
the fault situation.
Preventive maintenance
Preventive maintenance is carried out by qualified technical personnel on a
regular inspection and maintenance cycle basis, typically once or twice per year,
depending on local site conditions. The various systems are subjected to visual checks,
cleaning, measurement and replacement as the case may be the findings and the overall
state of the plant is documented.
Corrective maintenance
Corrective maintenance is performed in order to restore the desired state of
repair. To keep the restore time as short as possible spare part availability is a crucial
element. L’Obel Solar Power System always aims to increase the plant performance in
order to achieve the contractually agreed performance ratio.
Analysis and failure repair will be realized on various levels. Data input from the
electronic operation log in combination with the local inspection and measurements are
used to drive the effective measures. Failure repair due to system failures will be under
the service contract and no further cost for the service and the spare part will be
charged to the customer.
Facility management (by Customer)
This service compromises the care taking of the facility. Like visual inspection of
all outdoor plant installations from inside the plant fences as well as cleaning and minor
maintenance of building and fixed installations, e.g. maintenance of signage, oiling of
locks, exchange of light bulbs. As well the green management is contained like grass
and plant cutting to minimize shadows.
Module cleaning (by Customer)
Modules are exposed to the environment and depending on the local conditions
a dirt layer settles on the modules, which reduces the plant yield. Cleaning is executed
by a qualified service provider with a suitable cleaning method including man hours,
material and cleaning tools.

18
Security management (by Customer)
The substantial investment shall be safeguarded by e.g. 24/7 hrs monitoring of

8.1 Project Implementation Strategy
Overall project implementation will have the following stages of activities. These
stages are not mutually exclusive; to implement the project on fast track basis, some
degree of overlapping is anticipated.
Stage I - Project Development
Stage II - Finalization of the Equipment and Contracts
Stage III - Procurement and Construction (phased approach)
Stage IV - Plant Commission (phased approach)
Stage 1 – Project Development
Project development will begin with one or more visits to the region with the
objective of understanding regional ground conditions including socio-economic
conditions, transportation and infrastructure facilities available in the region. The key
step in this stage will be the negotiation and establishment of a power purchase
agreement (PPA) with the utility company. Following specific activities/tasks will be
completed during this stage:
 Land acquisition
 Preparation and submission of Detailed Project Report (DPR)
 Power purchase agreement (PPA)
 Expedite Central Regulatory Authority clearance
During this phase, a project team consisting of engineers, logistics experts and
project managers will be formed for the execution of the project. This project team will
work together from the earliest stages of the project, according to member’s specific
expertise, and will be responsible for:
 Planning project execution including development of GANTT charts
 Inspection of fabrication items and other equipment
 Supervise construction and commissioning of the plant

 Controlling and managing contractor payments
 Monitoring and managing project progress
 Maintaining project budget and schedule
Stage II – Finalization of Equipment and Contracts
In this stage, procurement packages are developed to send to suppliers for
detailed and final costs for all services and products. It is expected that detailed
engineering design will overlap with this stage and specifications for major equipment
will be developed in parallel with information from vendor catalogs and specification
sheets. For a solar installation, typically, solar panels and combiner boxes are the
longest lead items and project planning must provide adequate time period for the
acquisition and installation of these equipment.
This stage calls for close and constant communication between the project
engineers, equipment suppliers and vendors, and procurement specialists to ensure that
all documentation is made in strict accordance with project specifications and schedule.
Stage III – Procurement and Construction
Following contract award and issuance of purchase order, the project team will
follow up regularly to ensure smooth and timely execution of the contract. The
procurement activity includes review of drawings, stage and final pre delivery
inspection, and supervision of installation and construction. During construction, the
erection and commissioning phase of multiple contracts will proceed simultaneously.
Stage IV – Erection and Commissioning Phase
It is the commissioning phase where design, manufacturing, erection and quality
assurance expertise are put to test. The commissioning team will consist of key
equipment manufacturers of the equipment, L’Obel Solar Power System engineers, and
other specialized experts, where necessary. First step during commissioning is to use a
designed check list to ensure that the plant has been properly installed with appropriate
safety measures. The commissioning team will follow the internal operating
instructions. The plant shall be subjected to a performance test before synchronizations.
The plant shall be subjected to a performance test before synchronization under the
supervision of professional engineers/consultants.

21

There are two types of power generation schemes. The project engineering
changes according to this generation scheme. A brief introduction on the different
power generation scheme is given below.
9.1 Procurement of the System
Being a well recognized player in the international market, L’Obel Solar Power
System enjoys well proven relations with its suppliers. Our partners and suppliers have
been assessed not only for fulfilling the L’Obel Solar Power System quality standards
but also for their capability to professionally realize large – scale projects on time. Hence
L’Obel Solar Power System will procure project components directly from its vendors.
Procurement process includes the following broad activities:
 Procurement of modules
 Procurement of balance of system (BOS)
 Procurement of transmission system accessories and
 Procurement of other project components
L’Obel Solar Power System will procure the project components from various
sources under the onshore contracts and offshore contracts. This will be done with the
suitable entities at the time of procurement of the project components.
Some of the general information about the equipments that will be utilized in the
power plant is given below for the reference of the customer.
9.2 Typical System Integration
The panels will be ground mounted. The ground mounting will require a flat
level surface and will be set into concrete. The panels will require an area which is not
shaded. Any vegetation underneath the panels will need to be kept to a level below that
of the panels in order to avoid shading. All the panels will be at least 0.8 m from the
ground. It is assumed that this is adequate to keep the panels above the flood height of
the site.
The panels will be mounted in rows and electrically connected with cables. The
cable will need to be made safe and tamper proof. The electrical output from the PV
panels will be fed via cables to a bank of inverters.
The inverters will be housed in a structure to protect them from the weather and
from tampering. A design decision based on cost will need to be made whether the
inverters are all located in one area or are interspersed around the site.
22

The power plant will have a SCADA system to monitor the output of the rows of
panels. In this way, any system faults can be detected to a particular array and rectified.
Electrical protection equipment with be required, to be specified in conjunction with
PEA, for the connection of the PV plant to the electrical network.
