EXECUTIVE SUMMARY The Electricity Act, 2003, paves way for an innovative approach to solve our country’s power problems. It has paved the way for a competitive environment; open access to existing transmission and distribution network to transmit electricity across regions; de-licensing of generation, captive power and dedicative transmission lines; licensing of distribution and supply companies and the restructuring of State Electricity Boards
The Ministry of Power have a mandate to promote cogeneration and renewable sources for Power generation under Nodal agencies and hence it will play a major role in mainstreaming renewable energy sector.
The advantage or renewable
resources includes their capacity to produce energy without producing carbonbased warming and polluting agents into the atmosphere. The financial cost of its applications is not always cheap but if the environmental costs of using fossil are accounted for, renewable energy wins hands-down. There are also indirect savings on health and its costs as there are no harmful emissions.
In the above backdrop, Sahil Energy Pvt. Ltd., has decided to set up a 5MW Solar Power Plant. This Detailed Project Report (DPR) brings out all technical details and overall costs justifying the selection of the project. The total power generation is envisaged to be 5MW from Solar Photovoltaic Cell. It is a very important document that is required for Environmental Impact Assessment (EIA) studies, fixation of tariff, finalizing Power Purchase Agreement (PPA) and also for submission to Financial Institutions for obtaining project funding. The total project cost is expected to be Rs85 Crores and the average cost of generation is expected to be Rs.12.86 /kWh.

SECTION - 1 INTRODUCTION TO THE PROJECT
5|Page
INTRODUCTION World Economic growth is driven by energy, whether in the form of finite resources such as coal, oil and gas or in renewable forms such as hydroelectric, wind, solar and biomass or its converted form.
This energy generation and consumption
strengthens the nation’s industries, vehicles, homes and offices.
It also has
significant impact on the quality of the country’s air, water, land and forest resources. For future growth to be both rapid and sustainable, it needs to be as resource efficient and environmentally benign as possible. GENERATION OF ELECTRICITY & IMPORTANCE OF RENEWABLE ENERGY The growth in installed power generating capacity has not kept pace with the projected demand. To solve this problem, it is necessary to set up more power plants and most of these power plants will be either fossil fuel based or hydro electric units. However, the conventional power stations cause enormous damage to be environment due to pollution and other side effects. Renewable energy sources energy source are wonderful options because they are limitless. These will not be exhausted though fossil fuel will be gradually exhausted in course of time. Also another great benefit from using renewable energy is that most of these sources do not pollute the environment; the way burning of fossil fuels dose. SOURCE OF GREENHOUSE GAS The greenhouse gas emissions (GHG) come primarily from the combustion of fossil fuels in energy use. Energy use is largely driven by economic growth with shortterm fluctuations in its growth rate created by weather patterns affecting heating and cooling needs, as well as changes in the fuel used in electricity generation. The burning of fossil fuels produces around 21.3 billion tones of Carbon Dioxide per year, but it is estimated that natural processes can only absorb about half of that amount, so there is a net increase of 10.65 billion tones of atmospheric carbon dioxide per year. Carbon dioxide is one of the GHG that enhances radioactive forcing and contributes to global warming, causing the average surface temperature of the earth to rise. Environment scientists predict that this will cause major adverse effects, including reduced biodiversity.

The electricity sector is unique among industrial sectors in its very large contribution to emissions associated with nearly all air issues. Electricity generation produces a large share of nitrogen oxides and sulphur dioxide emissions, which contribute to smog and acid rain and the formation of fine particulate matter in addition to carbon dioxide. In addition, this sector has significant impacts on water and habitat and species. In particular, hydro dams and transmission lines have significant effects on water and biodiversity WORLD ENERGY SCENARIO It was estimated that in 2005, 86% of primary energy production in the world came from burning fossil fuels, with the remaining non-fossil sources being hydroelectric 6.3%, nuclear 6.0%, and renewable energy sources, i.e. geothermal, solar, wind, biomass and wastes contributed only 0.9%. BACKGROUND OF THE PROJECT Large multi-megawatt PV plants, approximately to 50 MW, are now in operation in the world. Solar Photovoltaic (PV) is known to be an important energy source for developing countries like India. Its importance is now being reaffirmed even by developed countries in view of its renewable and environment friendly character.
In our
country also, optimum utilization of solar energy could not only lead to savings in conventional energy but also result in many indirect benefits. In India 2MW solar PV now are commercially operated by independent power producer. But till now solar technology is expensive compared to other technology and significant financial assistance from government is needed to the developers and operators of new plants. In view of this, the Ministry of New & Renewable Energy Sources has been promoting electricity generation from Solar PV in Mega-Watt level. These projects are covered under the Grid Interactive Solar PV Power Generation Projects of Ministry of New & Renewable Energy Sources, Govt. of India. The Ministry initiated the programme to establish as a viable and environment friendly electricity generation option.

BARRIERS IN DEVELOPMENT OF THE PROJECT
The project has been identified with some barriers as mentioned below: (a)
Higher capital cost – The initial capital investment of the project is so high compared to other conventional power Project, so per MW cost is high.
(b)
Low Capacity Utilization factor – the total unit generation is low compared to other electricity generation system, because maximum of 6 hours in a day plant gets the solar light and generates the power.
The project being first of its kind in the state, thee could be more risks and barriers which might surface as the project progresses and it is difficult to enumerate all at this stage. BENEFITS OF GRID CONNECTED SOLAR PV POWER PLANT (a)
Power from the sun is clean, silent, limitless and free
(b)
Photovoltaic process releases no CO2, SO2 or NO2 gases which are normally associated with burning finite fossil fuel reserves and don’t contribute to global warming.
(c)
Photovoltaics are now a proven technology which is inherently safe as opposed to other fossil fuel based electricity generating technologies.
(d)
No fuel is required for generation, so fuel cost of power generation is zero.
(e)
Solar power shall augment the needs of peak power needs
(f)
Increase the grid reliability i.e., voltage and frequency
(g)
Solar Powered Grid Connect Plants can act as tail end energizers, which in turn reduces the transmission and distribution losses.
(h)
Provides a potential revenue source in a diverse energy portfolio
(i)
Assists in meeting renewable portfolio standards goals
(j)
Generation of electricity from Solar PV is totally free of Green House Gas emission.

SECTION - 3 DEMAND ANALYSIS AND JUSTIFICATION OF THE PROJECT
11 | P a g e
INTRODUCTION It is well know fact that electricity is the most essential input for growth and development of any state. Andhra pradesh is planning to go rapidly in both the industrial and agricultural sectors and consequently the demand for power is on the rise. However, despite Andhrapradesh possessing immense potential of power ranging from Coal to natural gas not taken place on a scale commensurate with the possibilities. As a result there exists a big gap between conventional and Nonconventional power generation for power in the State. SOLAR POWER POTENTIAL IN INDIA India is endowed with rich solar energy resource. The average intensity of solar radiation received in India is 200 MW/km square (megawatt per kilometer square), but the amount of solar energy produced in India is merely 0.5% compared to other energy resources till date India just have 2.12 megawatts of grid-connect solar generation capacity. As part of the National Solar Mission, the ministry aims to booster the annual photovoltaic production to at least 1,000 megawatts a year by 2017. With an installed capacity of 123 GW, the country currently faces energy shortage of 8 percent and a peak demand shortage of 11.6 percent, In order to sustain a growth rate of 8 percent, it is estimated that the power generation capacity in India would have to increase to 306 GW in the next ten years which is 2.5 times current levels.

SECTION - 4 TECHNICAL FEATURE & EQUIPMENTS OF THE PLANT
14 | P a g e
BASIC SYSTEM DESCRIPTION Solar Photovoltaic power generator consists of solar modules in series and parallel connections, these convert solar radiations into DC electrical power at the pre-determined range of Voltages whenever sufficient solar radiation is available. The individual crystalline solar cells are connected together in a module (in series connection), which are hermetically sealed to survive in rugged weather conditions and ensures optimum performance during its ling life In order to achieve a higher system voltage, modules are installed in a row arrangement, called a string. A higher system voltage has the advantage of lesser installation work, higher efficiency of the entire plant and usage of smaller cross section cables. Calculated no. of strings is connected in parallel by cables in Junction Boxes. These junction boxes not only act as a junction point but also monitor each string output which will be fed to the central monitoring and analysis system. Outputs from many such junction boxes are connected in parallel in the Main Combiner Box (MCB). This Main Combiner Box output is fed to the central inverters/Power Control Unit (PCU) to invert solar generated DC power in to conventional 3 phase AC power. Central inverter or PCU operate on MPPT (Maximum power point tracking) mode to ensure maximum output from the solar generators at different ambient conditions. Central inverters use higher system voltages to reach very high plant efficiency. Furthermore, installations can be expanded with additions of more modules without problems. AC power from inverters will be fed to LV panel which in turn will be stepped up through transformer. Power at 11kv/22Kv will be transmitted by overhead transmission line to grid.

SECTION - 7 SWOT ANALYSIS
36 | P a g e
SWOT ANALYSIS. Non – Conventional Sources, which are renewable in nature, are termed as the alternate sources of energy. The Challenges of the present – energy scenario offer us a window of the opportunity in the form of renewable energy sources. The Power from the sun is clean , silent , limitless and free. Photovoltaic (PV) process releases no CO2 , SO2 or NO2 gases which are normally associated with burning finite fossil fuel reserve and don’t contribute to global warming . Solar power shall augment the need of peak power needs & increases the grid reliability I.e , Voltage and frequency. Solar Powered grid connect plants can act as tail end energizes , which in turn reduces the transmission and distribution losses. (a)
Geographically India is situated at northern hemisphere near the Equator. So India gets maximum solar irradiation and there is ample of scope to produce the power from solar PV. But till now this area is totally virgin area for producing power.
(b)
This is true that solar PV efficiency is very low compared to other power generation systems , Lots of R&D is going on the improve the efficiency. Solar PV generates electricity only at day time , So the proposed solar PV Power plant generates power on an average only about six hours in day time.
(C)
India is potentially one of the largest markets for solar energy in the world. The estimate4d potential of power generation through solar photovoltaic system is about 20 MW/Sq.km in India. It is useful for providing grid quality, reliable power in rural area where the line voltage is low and insufficient cater to connected load. Recent Government incentives and policies have been providing the momentum for PV in India . The Government of India already declared national Action plan on climate change released in mid 2008, identifies eight critical mission – one of which is the National Solar Mission.
(d)
In comparison to other sources of power generation, the PV solar power is totally dependent in nature . The capacity utilization factor of such type of plant is only 19%. Because averagely in the year we get 6 hr sunlight
37 | P a g e
in a day . Only this particular interval solar plant generates electricity. In comparison to other conventional power generating units, solar power generating unit has many advantages like.
(a)
No fuel is required for power generation.
(b)
Operation & Maintenance Manpower required is less.
( c)
Plant will be running smoothly for a long period as compared to other conventional power generation units.
(d)
In environmental perspective , solar power plant generates clean energy and gets maximum clean development mechanism (CDM) benefit as compared to other conventional power generation units.
Considering all the above points, solar power generating potential is always ahead of all other conventional power generating units in economical & Environment point of view.

EXECUTIVE SUMMARY The Electricity Act, 2003, paves way for an innovative approach to solve our country’s power problems. It has paved the way for a competitive environment; open access to existing transmission and distribution network to transmit electricity across regions; de-licensing of generation, captive power and dedicative transmission lines; licensing of distribution and supply companies and the restructuring of State Electricity Boards
The Ministry of Power have a mandate to promote cogeneration and renewable sources for Power generation under Nodal agencies and hence it will play a major role in mainstreaming renewable energy sector.
The advantage or renewable
resources includes their capacity to produce energy without producing carbonbased warming and polluting agents into the atmosphere. The financial cost of its applications is not always cheap but if the environmental costs of using fossil are accounted for, renewable energy wins hands-down. There are also indirect savings on health and its costs as there are no harmful emissions.
In the above backdrop, Sahil Energy Pvt. Ltd., has decided to set up a 5MW Solar Power Plant. This Detailed Project Report (DPR) brings out all technical details and overall costs justifying the selection of the project. The total power generation is envisaged to be 5MW from Solar Photovoltaic Cell. It is a very important document that is required for Environmental Impact Assessment (EIA) studies, fixation of tariff, finalizing Power Purchase Agreement (PPA) and also for submission to Financial Institutions for obtaining project funding. The total project cost is expected to be Rs85 Crores and the average cost of generation is expected to be Rs.12.86 /kWh.

SECTION - 1 INTRODUCTION TO THE PROJECT
5|Page
INTRODUCTION World Economic growth is driven by energy, whether in the form of finite resources such as coal, oil and gas or in renewable forms such as hydroelectric, wind, solar and biomass or its converted form.
This energy generation and consumption
strengthens the nation’s industries, vehicles, homes and offices.
It also has
significant impact on the quality of the country’s air, water, land and forest resources. For future growth to be both rapid and sustainable, it needs to be as resource efficient and environmentally benign as possible. GENERATION OF ELECTRICITY & IMPORTANCE OF RENEWABLE ENERGY The growth in installed power generating capacity has not kept pace with the projected demand. To solve this problem, it is necessary to set up more power plants and most of these power plants will be either fossil fuel based or hydro electric units. However, the conventional power stations cause enormous damage to be environment due to pollution and other side effects. Renewable energy sources energy source are wonderful options because they are limitless. These will not be exhausted though fossil fuel will be gradually exhausted in course of time. Also another great benefit from using renewable energy is that most of these sources do not pollute the environment; the way burning of fossil fuels dose. SOURCE OF GREENHOUSE GAS The greenhouse gas emissions (GHG) come primarily from the combustion of fossil fuels in energy use. Energy use is largely driven by economic growth with shortterm fluctuations in its growth rate created by weather patterns affecting heating and cooling needs, as well as changes in the fuel used in electricity generation. The burning of fossil fuels produces around 21.3 billion tones of Carbon Dioxide per year, but it is estimated that natural processes can only absorb about half of that amount, so there is a net increase of 10.65 billion tones of atmospheric carbon dioxide per year. Carbon dioxide is one of the GHG that enhances radioactive forcing and contributes to global warming, causing the average surface temperature of the earth to rise. Environment scientists predict that this will cause major adverse effects, including reduced biodiversity.

The electricity sector is unique among industrial sectors in its very large contribution to emissions associated with nearly all air issues. Electricity generation produces a large share of nitrogen oxides and sulphur dioxide emissions, which contribute to smog and acid rain and the formation of fine particulate matter in addition to carbon dioxide. In addition, this sector has significant impacts on water and habitat and species. In particular, hydro dams and transmission lines have significant effects on water and biodiversity WORLD ENERGY SCENARIO It was estimated that in 2005, 86% of primary energy production in the world came from burning fossil fuels, with the remaining non-fossil sources being hydroelectric 6.3%, nuclear 6.0%, and renewable energy sources, i.e. geothermal, solar, wind, biomass and wastes contributed only 0.9%. BACKGROUND OF THE PROJECT Large multi-megawatt PV plants, approximately to 50 MW, are now in operation in the world. Solar Photovoltaic (PV) is known to be an important energy source for developing countries like India. Its importance is now being reaffirmed even by developed countries in view of its renewable and environment friendly character.
In our
country also, optimum utilization of solar energy could not only lead to savings in conventional energy but also result in many indirect benefits. In India 2MW solar PV now are commercially operated by independent power producer. But till now solar technology is expensive compared to other technology and significant financial assistance from government is needed to the developers and operators of new plants. In view of this, the Ministry of New & Renewable Energy Sources has been promoting electricity generation from Solar PV in Mega-Watt level. These projects are covered under the Grid Interactive Solar PV Power Generation Projects of Ministry of New & Renewable Energy Sources, Govt. of India. The Ministry initiated the programme to establish as a viable and environment friendly electricity generation option.

Higher capital cost – The initial capital investment of the project is so high compared to other conventional power Project, so per MW cost is high.
(b)
Low Capacity Utilization factor – the total unit generation is low compared to other electricity generation system, because maximum of 6 hours in a day plant gets the solar light and generates the power.
The project being first of its kind in the state, thee could be more risks and barriers which might surface as the project progresses and it is difficult to enumerate all at this stage. BENEFITS OF GRID CONNECTED SOLAR PV POWER PLANT (a)
Power from the sun is clean, silent, limitless and free
(b)
Photovoltaic process releases no CO2, SO2 or NO2 gases which are normally associated with burning finite fossil fuel reserves and don’t contribute to global warming.
(c)
Photovoltaics are now a proven technology which is inherently safe as opposed to other fossil fuel based electricity generating technologies.
(d)
No fuel is required for generation, so fuel cost of power generation is zero.
(e)
Solar power shall augment the needs of peak power needs
(f)
Increase the grid reliability i.e., voltage and frequency
(g)
Solar Powered Grid Connect Plants can act as tail end energizers, which in turn reduces the transmission and distribution losses.
(h)
Provides a potential revenue source in a diverse energy portfolio
(i)
Assists in meeting renewable portfolio standards goals
(j)

SECTION - 3 DEMAND ANALYSIS AND JUSTIFICATION OF THE PROJECT
11 | P a g e
INTRODUCTION It is well know fact that electricity is the most essential input for growth and development of any state. Andhra pradesh is planning to go rapidly in both the industrial and agricultural sectors and consequently the demand for power is on the rise. However, despite Andhrapradesh possessing immense potential of power ranging from Coal to natural gas not taken place on a scale commensurate with the possibilities. As a result there exists a big gap between conventional and Nonconventional power generation for power in the State. SOLAR POWER POTENTIAL IN INDIA India is endowed with rich solar energy resource. The average intensity of solar radiation received in India is 200 MW/km square (megawatt per kilometer square), but the amount of solar energy produced in India is merely 0.5% compared to other energy resources till date India just have 2.12 megawatts of grid-connect solar generation capacity. As part of the National Solar Mission, the ministry aims to booster the annual photovoltaic production to at least 1,000 megawatts a year by 2017. With an installed capacity of 123 GW, the country currently faces energy shortage of 8 percent and a peak demand shortage of 11.6 percent, In order to sustain a growth rate of 8 percent, it is estimated that the power generation capacity in India would have to increase to 306 GW in the next ten years which is 2.5 times current levels.

BASIC SYSTEM DESCRIPTION Solar Photovoltaic power generator consists of solar modules in series and parallel connections, these convert solar radiations into DC electrical power at the pre-determined range of Voltages whenever sufficient solar radiation is available. The individual crystalline solar cells are connected together in a module (in series connection), which are hermetically sealed to survive in rugged weather conditions and ensures optimum performance during its ling life In order to achieve a higher system voltage, modules are installed in a row arrangement, called a string. A higher system voltage has the advantage of lesser installation work, higher efficiency of the entire plant and usage of smaller cross section cables. Calculated no. of strings is connected in parallel by cables in Junction Boxes. These junction boxes not only act as a junction point but also monitor each string output which will be fed to the central monitoring and analysis system. Outputs from many such junction boxes are connected in parallel in the Main Combiner Box (MCB). This Main Combiner Box output is fed to the central inverters/Power Control Unit (PCU) to invert solar generated DC power in to conventional 3 phase AC power. Central inverter or PCU operate on MPPT (Maximum power point tracking) mode to ensure maximum output from the solar generators at different ambient conditions. Central inverters use higher system voltages to reach very high plant efficiency. Furthermore, installations can be expanded with additions of more modules without problems. AC power from inverters will be fed to LV panel which in turn will be stepped up through transformer. Power at 11kv/22Kv will be transmitted by overhead transmission line to grid.

SECTION - 7 SWOT ANALYSIS
36 | P a g e
SWOT ANALYSIS. Non – Conventional Sources, which are renewable in nature, are termed as the alternate sources of energy. The Challenges of the present – energy scenario offer us a window of the opportunity in the form of renewable energy sources. The Power from the sun is clean , silent , limitless and free. Photovoltaic (PV) process releases no CO2 , SO2 or NO2 gases which are normally associated with burning finite fossil fuel reserve and don’t contribute to global warming . Solar power shall augment the need of peak power needs & increases the grid reliability I.e , Voltage and frequency. Solar Powered grid connect plants can act as tail end energizes , which in turn reduces the transmission and distribution losses. (a)
Geographically India is situated at northern hemisphere near the Equator. So India gets maximum solar irradiation and there is ample of scope to produce the power from solar PV. But till now this area is totally virgin area for producing power.
(b)
This is true that solar PV efficiency is very low compared to other power generation systems , Lots of R&D is going on the improve the efficiency. Solar PV generates electricity only at day time , So the proposed solar PV Power plant generates power on an average only about six hours in day time.
(C)
India is potentially one of the largest markets for solar energy in the world. The estimate4d potential of power generation through solar photovoltaic system is about 20 MW/Sq.km in India. It is useful for providing grid quality, reliable power in rural area where the line voltage is low and insufficient cater to connected load. Recent Government incentives and policies have been providing the momentum for PV in India . The Government of India already declared national Action plan on climate change released in mid 2008, identifies eight critical mission – one of which is the National Solar Mission.
(d)
In comparison to other sources of power generation, the PV solar power is totally dependent in nature . The capacity utilization factor of such type of plant is only 19%. Because averagely in the year we get 6 hr sunlight
37 | P a g e
in a day . Only this particular interval solar plant generates electricity. In comparison to other conventional power generating units, solar power generating unit has many advantages like.
(a)
No fuel is required for power generation.
(b)
Operation & Maintenance Manpower required is less.
( c)
Plant will be running smoothly for a long period as compared to other conventional power generation units.
(d)
In environmental perspective , solar power plant generates clean energy and gets maximum clean development mechanism (CDM) benefit as compared to other conventional power generation units.
Considering all the above points, solar power generating potential is always ahead of all other conventional power generating units in economical & Environment point of view.
