(A) 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 carbon-

based 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.

1.0 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.

2.0 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.

3.0 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 short-

term 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

4.0 GREEN HOUSE GAS CONCENTRATION TRENDS

The atmospheric concentration of CO2 has increased by 31% since 1750 and

continues to increase, on average, by 1.5 ppm or 0.4% per year. About 80% of the

anthropogenic emissions of CO2 during the past 20 years is due to fossil fuel

burning and cement production. The rest is due to deforestation. The atmospheric

concentrations of CH4 and N2O have increased by 151% and 17%, respectively,

since 1750. The table given below shows the 20th Century changes in the Earth’s

atmosphere system for selected GHGs.

5.0 ATMOSPERIC LIFETIME & GLOBAL WARMING POTENTIAL (GWP) FOR SOME GREEN HOUSE GASES

5.1 CARBON DIOXIDE (CO2)

CO2 It has a variable atmospheric lifetime, and cannot be specified precisely.

Recent studies indicate that recovery from a large input of atmospheric CO2 from

burning fossil fuels will result in an effective lifetime of tens of thousands of years.

Carbon dioxide to have a GWP of 1 over all time periods.

5.2 METHANE (CH4)

Methane has an atmospheric lifetime of 12+3 years and a GWP of 62 over 20 years,

23 over 100 years and 7 over 500 years. The decrease in GWP at longer timer is

because methane is degraded to water and CO2 by chemical reactions in the

atmosphere.

5.3 NITROUS OXIDE (NOX)

Nitrous Oxide has an atmospheric lifetime of 120 years and a GWP of 296 over 100

years

5.4 CFC 12

CFC – 12 has an atmospheric lifetime of 100 years and a GWP of 106000 over 100

years

5.5 HCFC – 22

5700 over 100 years

5.7 SULPHUR HEXAFLUORIDE (SF6)

SF6 has an atmospheric lifetime of 3,200 years and a GWP of 22000 over 100

years

6.0 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%.

7.0 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.

8.0 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.

9.0 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.

10.0 CHOICE OF TECHNOLOGY

Proposed power plant converts sunlight directly into electrical energy by Solar PV

Module. It produces DC current.

There are two types of solar power plants, mainly

(a) Stand alone

(b) Grid Connected

In Grid Connected type power plant, Modules supplies DC current to inverter. Then DC is converted to low voltage AC current. AC power is stepped up by 415 / 11 kV step up transformer & fed to the grid.

Now a days there are two types of solar cells available in market

(a) Amorphous type(b) Crystalline type(c) Thin Film (CIGS/CdTe) type

The efficiency of amorphous is less than crystalline. So, more area is needed to set up same capacity solar plant with amorphous type cells.

Polycrystalline solar cells are used in proposed solar power plant.

1.0 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 Non-

conventional power generation for power in the State.

2.0 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.

4.0 SOLAR ENERGY POTENTIAL IN MAHARASHTRA

Solar power plants are a necessity at places in Andhra Pradesh for providing

electricity to improve the standard of living of the people. Financial constraints in

the public sector and non-remunerative characteristics of economics act as

disincentives to private entrepreneurs.

Till now, no grid connected solar power plant is being setup in AP though some of

projects are already sanctioned. Nodal agency of Energy, NEDCAP has already

announced tariff policies for solar energy as per MNRE rules

The proposed plant may be the first kind of Solar Power Plant in state that

supplies the solar electricity to the grid

4.1 Promotion Policies of MNRE

4.3 Clean Development Mechanism (CDM)

Normally grid connected power plants generate electricity by burning fossil fuel,

which results in GHG emissions and other associated emissions like Sox and

NOx. The proposed power plant project activity aims at reducing these GHG

emissions in addition to power generation by installing a 1.0 MW Solar power

generation plant, to supply power to the Grid

(b) How CDM Works?

An investor from a developed country can invest in, or provide finance for a

project in a developing country that reduces greenhouse gas emissions so that

they are lower than they would have been without the extra investment- i.e.

compared to what would have happened without the CDM under a business as

usual outcome. The investor then gets credits- carbon credits-for the reductions

and can use those credits to meet their Kyoto target. If the CDM works perfectly it

will not result in more or less emission reduction being achieved than were agreed

under the Kyoto protocol, it will simply change the location in which some of the

reductions will happen. For example, a French company needs to reduce its

emissions as part of its contribution to meet France’s emission reduction target

under the Kyoto Protocol. Instead of reducing emissions from its own activities in

France, the company provides funding for the construction of a new biomass plant

they argue, prevents the construction of new fossil-fueled plants in India, or

displaces consumption of electricity from existing ones, leading to Global

1.0 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.

2.0 OPERATION PHILOSOPHY

Solar panels mounted in the field generate DC electric power. The DC electric

power generated by the solar panels cannot be fed directly in to the utility grid.

The GCI range of inverters invert the direct current output from the solar array

into grid compliant AC voltage, feeds it in to the utility grid system with proper

Page 25: DPR 5MW - Sahil Energy Kadiri - 1

protection and control. The grid connected inverter (GCI) range of inverters

comes with built-in transformer that ensures galvanic isolation of the DC side

from the AC network. This is an important requirement for many utilities to permit

connection of solar panels on to the grid. The system automatically starts up in

the morning and begins to export power to the grid, provided there is sufficient

solar energy and the grid voltage, frequency is within the range. If the grid goes

out of range the inverter will be immediately disconnected and reconnected

automatically at a pre determined time after the grid comes back within range.

When the exported power is very negligible for a pre determined time the system

will go into an sleep mode by disconnecting the inverter from the grid.

3.0 POWER GENERATION SCHEME

3.1 ELECTRICAL SYSTEM TYPES

There are two general types of electrical designs for PV power systems.

Systems that interact with the utility power grid and have no battery backup and

system that interact and include battery backup as well.

The former is most preferable and is explained below:

3.2 GRID INTERACTIVE SOLAR POWER PLANT

This type of system only operates when the utility is available. Since utility

outages are rare this system will normally provide the greatest amount of bill

savings to the customer per dollar of investment. However, in the event of an

outage, the system is designed to shut down until utility power is restored.

3.3 TYPICAL SYSTEM COMPONENTS

3.3.1 PV Array

A PV Array is made up of PV modules, which are environmentally-sealed

collections of PV cells-the devices that convert sunlight to electricity. Our solar

module of 200 Wp is being used in the proposed Project. The Module is of 1.67

M3. Often sets of four or more smaller modules are framed or attached together

by struts and that is called a paner.

4.1 SOLAR PV MODULES

A Photovoltaic module is a packaged interconnected assembly of

photovoltaic cells, which converts sunlight into energy. For this project,

crystalline type of solar module of 200 Wp is considered.

The tilt angle for the modules would be 300 (all the modules will be facing south.)

4.2 CENTRAL INVERTERS

The grid connected inverter range is a state of the art equipment with robust

control platform, high efficiency, high availability, low maintenance features

built with quality components. The Grid Connected Inverter (GCI) series

comes with built in isolation transformers. The product is available in range of

10 KVA to 250 KVA units in three phase configurations. The central inverters

(3-phase) will be designed with innovating, cutting edge technology.

Optimized efficiency factor, higher availability (by proven ling life

components), the latest control procedure are key features.

4.3 JUNCTION BOXES

In the junction boxes, Cable from individual module strings are bundled and

safely routed to the inverter. It is a combination of an exact, well organized

string monitoring system and a safety concept adapted to the PV technology.

The junction boxes will have suitable cable entry points fitted with cable

glands of appropriate sizes for both incoming an out going cables. They

monitor the output of solar PV arrays. If difference between string outputs is

too large, the operator is informed through monitoring system. These junction

boxes are enclosed in IP 55 rated poly-carbonate housing.

4.4 MODULE MOUNTING SYSTEM

The module mounting structure is design for holding suitable number of

modules in series. The frames and leg assembles of the array structure is

made of Mild Steel, hot dip galvanized material of suitable sections of Angle,

Channel, Tubes or any other section conforming to IS:2062 for steel

structure to meet the design criteria. All nuts & bolts considered for fastening

modules with this structure are of very good quality of stainless steel. The

array structure is designed in such a way that it will occupy minimum space

without sacrificing the output from SPV plants at the same time.

4.5 GRID CONNECTING EQUIPMENTS

Please refer enclosed singed line diagram PE-167-EL:-501.

Solar module generated power in DC from which power will be inverted from

DC to AC by using central inverters. AC power is fed to power control centre.

From PCC 3 phase 415V power will be further stepped up to 11kv/22Kv by

415/11 kv, 1.6 MVA x 5 Nos. transformer. Power will bye transmitted to grid

using 11kv/22Kv overhead line.

4.6 MONITORING SYSTEM

The system also enable diagnostic and monitoring functions for these

components.

4.7 CABLE AND CONNECTORS

Cables will be extremely robust and resist high mechanical load and

abrasion. High temperature resistance and excellent weatherproofing

characteristics provide a long service life to the cables used. The connectors

with high current capacity and easy mode of assembly are to be used for the

connections of the power plant cables.

4.8 TRANSFORMERS

The output power from the inverter is fed to 3 phase415/11kv, 1.6 MVA step

up transformer. The specifications of the transformer are provided in the

Data sheet for reference.

4.9 BUILDING FOR HOUSING THE ELECTRONICS (SUB-STATION)

The substation building will house all the electrical and electronic equipments

like Central inverters, Low Voltage Panels.

4.10 PANELS CLEANING SYSYTEM

In Developed countries, Solar PV Module Panels Dust cleaning system is

widely used in solar photovoltaic power station. Trees leaves, bird poop and

airborne particles (from dirt and pollen) make solar panels dirty, dirty panels

causes power loss. Dirt and debris reduce the ability of the solar array to

perform at full capacity. The potential energy loss depends on the level of

fifth accumulated on solar panels. Energy loss could reach 25 percent of

generating power. Cleaning system for solar panels will improve the

photovoltaic conversion rate; keep the generation capacity steady all over

the year capacity. Panels can ve cleaved either manually or mechanically.

In Mechanical cleaving system mainly, water sprinkler system is used, but it

needs lot of power to spray water in wide module area, Manual system need

manpower for cleaning. Though mechanical Dust cleaning system are

efficient than manual system. This solar PV plant manual cleaning is

proposed because the plant is situated in Village area where manual labour

cost is less compared to total auxiliary power cost.

5.0 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 units 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.

5.1 GRID SYNCHRONIZATION SCHEME

As per the grid synchronization is concerned, the power plant generates

power at 415 volts at the inverter terminal. The power plant will have

switchyard in the plant premises with single bus arrangement with one power

transformer with control and protection equipment (breaker, CTs, PTs,

isolators etc.)

Protection, metering for the switchyard and grid feeder will be

accommodated in outdoor Kiosk.

The power generated has to be synchronized with the substation. The

substation is about 3000 M away from the plant location.

The power generation by solar module will be inverted into AC from by GCI

and will be fed to the grid though 415 V/11kv step up transformer. The

scheme will have High tension metering cubicle. Air/ Vacuum circuit

breakers.

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

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.
