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 notreleases 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.

4. Introduction

Climate change and fossil fuel depletion are threatening our very existence onthis planet. This is primarily due to our dependence on fossil fuels for an upkeep ofmodern day life styles. Nearly 75% of energy usage takes place in urban and semi-urban areas accommodating large chunks of population. The rapid urbanization withan accompanying economic development is responsible for a sudden rise in energydemand. Essential public services like electricity services for homes, transport, industry,commerce, and other infrastructure run by virtue of fossil fuels. To secure the energysupply for all this and to mitigate the risks of climate change, RE source of energy formthe most obvious solution. With its abundant solar energy, India can exploit thisresource easily.

Most of today’s electrical energy is generated by fossil fuel based plant with alow production cost and high reliability. However, concerns about the longer termsustainability 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 powergeneration and solar in specific by its current policies.

India is a tropical country, where sunshine is available for longer hours per dayand in great intensity. It is home to one of the most abundant solar resources in theworld, with 2.97 million square kilometres of tropical and subtropical land and anaverage of 300 clear sunny days a year. As such, solar power offers significant potentialto meet a large share of the country's energy needs.

Solar energy, therefore, has a tremendous potential as a future energy source. Ithas the advantage of permitting decentralized distribution of energy, large, centralizedpower generation plants, smaller distributed heat and power plants; or scaled down, atthe individual consumer level. Thus it has the leverage of empowering people at grassroot level.

It is not only technically and economically feasible for India to make the shift torenewable energy sources (if this rollout is combined with energy-efficiency measures),but also prudent to begin this transition now. The Government has recently approvedan 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 andeliminate 42 million tons of carbon dioxide emissions annually.

There are several reasons for this urgency. First, India's power-generationinfrastructure is undergoing rapid expansion to meet national development objectives,with the country still facing unmet power demands that equate to as much as 80 percentof current installed capacity. Second, they point to rising energy security concerns as


6/30

energy prices go up and supplies shrink, making it a ripe time to shift to a new model ofenergy production.

As on March, 2009, India’s power system had an installed generating capacityaround 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. Hydropowerpicks up a share of 24.80%. Renewable sources of energy account for around 8% of thepower generated, with wind power having a share of around 5.5%. In the same year acapacity addition of nearly 51,300 MW has been planned by the ministry of powerduring the eleventh five year plan period (2009-2012).Thus there is a need for large scalepower generation from both Non-renewable and renewable sources of energy to sustaina targeted GDP growth of 8%to 10% per year.

Of late, solar power investments in the country are registering a fast increase. Infact, 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 thatsolar 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 wehave a need to cut down the GHG emissions, it also has to ensure that its infrastructuralgrowth is not hindered in any way. Solar energy in India is a potential huge source ofenergy. If we are able to harness the high amount of sunlight received by India, then wecan meet its energy demand like no other fuel.

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 purchaseagreement (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 willwork 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


20/30

20

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 projectengineers, 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

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.


23/30

23

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.
