1.2 Comparison of benefits of (2x150 MW) units over (2x135 MW + 1x30 MW)

units.

It is proposed to install (2x150 MW +50 MW) units in place of earlier proposed

(2x135 MW +30MW +50 MW) units.

Reasons for installing the presently proposed (2x150 MW) units instead of

(2x135 MW +30MW) units are:

1. The inefficient, non re-heat type 30 MW unit has very High Turbine Heat Rate, Low Boiler Efficiency and hence Very High Specific Coal Consumption. Hence we have discarded the 30 MW Unit.

2. The proposed 150 MW units have lower Turbine Heat Rate, higher Boiler Efficiency and hence Lower Specific Coal Consumption in comparison to 135 MW units.

Thus the configuration with (2x150 MW +50 MW) units have following

advantages over the configuration with (2x135 MW +30MW +50 MW) units.

� Coal Consumption shall be reduced by about 1.87Lac MT/Year (7.42% ). � Total Ash produced shall be reduced by about 0.70 lac MT/Year (6.30% ).

� Exit Volume of Flue Gas shall be reduced by about 22127 NM3/hr. � Gross Pollution Load (Air) shall be reduced by about 8.76Tonnes/ year.

� Water consumption shall be reduced by about 0.51 MCM/Year (6%).

� Chimney Height for (2x150 MW) units shall be 220 Meters for better dispersion of emission.[ Chimney Height for (2x135 MW +30MW) units was kept at 180 Meters.]

(An approximate comparison of these factors is enclosed in the report).

CHAPTER-II

Introduction of the project / Background information

2.1 Identification of Project and Project Proponent

Sarda Energy & Minerals Ltd. (Formerly Chhattisgarh Electricity Company Ltd.),

Incorporated on 23rd January 1998, is a Public Limited Company. Power has been

the prime mover of growth in the Company. The Company had installed 20 MW coal

based thermal power plant, which commenced operations in the year 2001, gradually

the capacity of power plant has been increased to 81.5 MW. The Company also

installed five 9 MVA Submerged Arc Ferro alloys furnaces in phases to use captive

power from power Plant and to have maximum realization for the power generated

presently total capacity of plant is 45 MVA, which makes company the second largest

producer of manganese based Ferro Alloys in the country. The facilities are installed

at Industrial Growth Centre, Siltara, Raipur over an area of about 70 acres.

Chhattisgarh Electricity Company Ltd. has got merged with Raipur Alloys & Steel

Limited as per the orders of Hon’ble High Court of Chhattisgarh, Bilaspur dated 11th

May, 2007 & the name of Raipur Alloys & Steel Limited has also been Changed to

“Sarda Energy & Minerals Limited”(SEML) as per Fresh Certification of Incorporation

dated 2nd August 2007. Liberalization of economy by the Government, throwing open

for manufacturing of Iron and Steel including mining of iron ore, coal and other

related minerals to private entrepreneurs, provided an avenue for further growth in

this segment to SEML. Company is a industrial house to set up a modern integrated

steel plant at Siltara Industrial Estate, Raipur. The steel plant uses non-coking coal

for sponge iron production of 79,200 TPA, further it has expanded to 4,60,000 TPA

sponge iron production. Initially for meeting its requirement for 79,200 TPA sponge

iron, SEML obtained a mining lease for iron ore situated at Dongarbor in the

Rajnandgaon District, to produce 2.0 lakhs TPA. After expansion of sponge iron plant

to meet its requirement of iron ore, the company has increased production capacity

of Dongarbor Iron Ore Mine from 2.0 lakhs TPA to 15.0 lakhs TPA for extraction of

iron ore in the year 2007. Company has been allotted a captive coal block at Karwahi

near Tamnar, District- Raigarh, Chhattisgarh State to produce 1.2 Million TPA coal.

Company is proposed for installation of 1.1 Million TPA Integrated Steel Plant and 60

MW WHRB Power Plant at Siltara Industrial Growth Centre, Mandhar, Raipur.

2.2 Brief Description of nature of Project

Company proposes to install 350 MW power plant with a configuration of 2 x

150 MW + 1 x 50 MW. Coal for the proposed power project will made available

through company's own captive coal mines and middling generated from coal

Washery. The entire coal shall be transported through closed conveyor and

road from Mines / Washery to Plant site which is about 4.5 KM. Necessary

water required for power plant operation shall be taken from nearby Kelo



11

River. Power Generated shall be evacuated at 400 KV level by installing

dedicated power evacuation lines from plant to Tamnar Sub Station.

2.3 Need for the project and its importance to the country and or region

The Government of India’s 5th National Power Plan has envisaged a total installed

capacity of 2,12,000 MW as per the 16th Electric Power Survey. This capacity is to be

achieved by end of the 11th Plan, March 2012. The Government of India has

projected a GDP growth rate of about 7.4% based on power capacity to be achieved in

the 11th plan. To achieve a target of higher than 10,000 MW per annum, huge

investment in power sector is required and also the manufactures, contractors,

vendors and supporting will need to increase their capacities to meet this target of

power sector.

Presently state generating capacity in thermal and hydro power is about 1800 MW &

143 MW respectively. No. of villages are still to be electrified and presently there is a

power crises in the state which is affecting industrial production. In order to have a

10% GDP in the state the generating capacity of power has to be enhanced

Considerably.

In the 11th plan period in the state of Chhattisgarh the following departments are

planned to be enhanced the power generation.

1. Central sector – 4480 MW

2. State Sector - 3250 MW

3. Private Sector – 2950 MW

MOUs signed by various organizations for 42000 MW.

In order to complete the expansion plans in the area of steel and alloys it is essential

for the company to install captive power plants so that the cost of production shall be

competitive on Global basis.

State grid company desires companies to install their own power plant to meet

requirement and balance power can be for export. Company is presently having

generation capacity of 81.5 MW and they are also exporting upto 10 Mwh..

In view of the above M/s Sarda Energy & Minerals Ltd. (SEML) has decided to setup

a coal & middling based Thermal Power Plant with a total capacity of 350 (2x150 +

1x50) MW in District Raigarh, Chhattisgarh. SEML has retained Anacon Laboratories

Nagpur to undertake on Environmental Impact Assessment study and preparation of

Environment Management Plan for the proposed 350 MW Thermal Power Plant for

Environment Clearance from State Level Environment Impact Assessment Authority.

2.4 Demand -Supply Gap

PRESENT INSTALLED GENERATION CAPACITY

At the end of 1st quarter for the year 2010 the installed generation capacity in the

country are 159398.49 MW. Owing to the rapid industrialization all over the country

and in particular in eastern India which so far was neglected, is witnessing massive

investment both from foreign companies in form of FDI as well as from domestic

players in the field of iron & steel, Aluminium, chemical, mines, infrastructure & etc.

and for all these, power remains the most important driving force, but in the recent

past it has been observed that power generation is not keeping pace with rapid

industrialization, which in turn is increasing demand for power, that too quality

power, because the modern machineries which are being used nowadays are

sensitive & costlier, for smooth & continuous operation, these machineries require

quality power. Keeping these entire things in mind, India must change its present

status from being a power deficit country to a power surplus country to maintain a

steady GDP growth. The state of Chhattisgarh like many other eastern India states is

also witnessing huge investment in Iron & steel and aluminium sectors. As a result

power demand is increasing day by day. Therefore, to meet the huge demand of

power in Chhattisgarh as well as many adjoining states like Orissa, Jharkhand,

Madhya Pradesh, Uttar Pradesh & Maharashtra, the demand for power in these

states has witnessed a huge surge in the last five years due to rapid industrialization.

As the state of Chhattisgarh is strategically centrally located to these adjoining

states, it has got ready market for utilization of power generated in Chhattisgarh in

these areas, where the demand for power is huge. Moreover Chhattisgarh, especially

districts like Korba, Janjgir and Raigarh have got huge reserves of untapped

hydrocarbon fuels i.e coal, being so close to the primary fuel for a thermal power

station, the transportation cost of fuel to the envisaged site shall be minimal, as a

result the cost of power generation shall be drastically reduced.

MINISTRY OF POWER’S BLUEPRINT FOR POWER DEVELOPMENT

The energy shortage in the country during first quarter of 2010 was 8980 million

units amounting to 11.7 per cent shortage and the peak power shortage was 15748

MW translating to 13.3 per cent. The Ministry of Power has developed appropriate

strategies and a blueprint to address the power situation in the country in a time

bound manner. Based on the demand projections made over 100,000 MW of

additional generation capacity needs to be added by the year 2012 to bridge the gap

between demand and supply of power.

Upto march,2010 the installed generation capacity of the country was 159398.49

MW, peak availability was 102725 MW and the energy generated was 67513 Million

kWHr. The energy shortage in the country during first quarter of march, 2010 was

8980 million units amounting to 11.7 per cent shortage and the peak power shortage

was 15748 MW translating to 13.3 per cent as per CEA website in the chapter “Power

Scenario at a Glance”. To meet the shortfall as well as the future demand, several

new projects are proposed.

Capacity augmentations due to the projects which are under construction or

proposed and expected to be commissioned during XI plan (2007-2012) are in Table

below.

AVAILABILITY OF POWER

The power availability of the system is dependent on the following factors:

a) Planned outages due to maintenance, forced outages, etc.

b) Spinning reserve

c) Auxiliary power consumption

d) Stabilization period in case of newly commissioned units

e) Partial non-availability due to poor quality of indigenous coal, non availability of

gas, uncertain irrigation releases resulting in uncertainty of hydro generation at peak

hours, loss of active power due to high reactive demand of units.

Considering the peak power and energy availability from the existing plants, peak

power and energy availability of future plants based on the mix in development of

hydro, thermal and nuclear power plants projections are made for the region. The

projected peak power demand, power requirement, energy availability and energy

requirement along with the deficit or surplus are shown in table below.

From the above table, it is obvious that there is a deficit in the power availability and

energy availability in India. By the year 2012, Government of India has decided to

increase the power generation by 100000 MW. Coal is identified as the main fuel for

thermal power. The plants located in pit heads would have a greater economic and

logistical advantage in terms of cost of energy.

2.5 Employment Generation (Direct and Indirect) due to Project

The major benefit due to the proposed project will be in the sphere of generating

employment for about 700 persons in that area. The proposed project will benefit

local population. The manpower requirements for the operational phase of the Power

Plant will be about 700 people. In addition, there will be an indirect employment for

skilled/ semi skilled people during project life. All attempts will be made to employ

suitable, locally available, skilled personnel from the study area. In case of non-

availability of skilled persons, people will be employed from outside the study area.

COAL HANDLING SYSTEM

The coal required for Power Plant is of size - 30 mm and whereas the coal received

from the mine ( - 300 mm) & middling received from washery is of size < 10 mm .

Thus the coal received is required to be crushed and screened.

The coal received will be feed into ground hopper. This will be crushed and screened

to - 30 mm size. From the screen it will be fed into traveling tripping trolley installed

on the coal bunkers and the oversize coal will be again fed for re-crushing to crusher.

Traveling Tripper trolley installed above the Coal Bunker will facilitate uniform

distribution of the coal into the bunkers. The Coal handling system consists of the

following major equipments:

a] Ground Hopper

b] Impact Crusher

c] Vibrating Screen

d] Conveyor Belt

e] Traveling Tripper Trolley

f] Stacker and Reclaimer

COAL YARD

required.

PROCESS OF POWER GENERATION

Coal Based AFBC/CFBC/ PF Boiler – Capacity 2 X 520 TPH & 2 X 110 TPH

For Thermal Power Plant coal & water are the essential raw material in the process.

Coal & Middling will be transported from mines by road / conveyor. Coal received by

road is unloaded by truck tipper arrangement. The coal is brought to the coal

hoppers by conveyors. The coal from the hoppers is fed by vibro-feeder to a coal

conveyor. The coal from the conveyor is passed through coal crusher where the size

of the coal is reduced to -30 mm size. Subsequently the crushed coal is fed to the

vibratory screen where the size of the coal has been bifurcated in less than 30 mm &

more than 30 mm size. The Coal size having more than 30 mm is brought again to

the crusher the after crushing the size is reduced to less than 30 mm size. The coal

passing through vibrating screen of less than 30 mm size is transported through the

belt conveyor to the coal bunker. Now the coal available in the bunker is ready for

burning in the boiler.

Boiler

Boiler is provided with various auxiliaries such as ID Fan, FD, fan, PA fan, Coal

feeder, ESP, Ash handling system. The boiler is provided with various fittings duly

approved by IBR authorities.

Boiler consist of Steam Drum, water wall tube, PSH, SSH, Eco, Air heater. Initially

the DM water is filled in the boiler up to the center level of the Steam Drum provided

on the top of the boiler, This will ensure filling of DM water of all water side parts

such as economizer, bed coils, all the four walls of the boiler.

Initially ID fan started to maintain the natural draught in the furnace. Subsequently

FD fan will be started. The FD fan draws the air from the atmosphere and delivers to

the air heater and subsequently passes to air box / Burner provided with the boiler.

The PA fan is started to convey coal inside the Boiler after attaining ignition

temperature.

Lighting up of the Boiler is done through LDO , after achieving the temp. more than

600 Deg C of the furnace, the PA fan and Coal feeders/ Mills will be started.

Subsequently the coal of the desired quantity is fed into the boiler. The quantity of



34

the coal injected into the furnace is slowly increase to achieve the boiler design

parameters.

The heat generated due to burning of the coal will be absorbed in the boiler parts and

the flue gases will be passed through various parts of the boiler so that the final gas

temperature achieve to 140 to 150 Deg C and finally pass through ESP, ID, Chimney

and to the atmosphere. While passing the dust-laden gas in the ESP, all the dust is

removed to the hoppers of the ESP and subsequently pass to the ash storage silo.

Boiler is generating steam of the desired parameters of the turbine and the generated

steam is passed through the turbine.

Turbine

The Steam Turbine is directly coupled with Generator and Exciter. Steam is passed

through turbine and at the last stage it is passed through the condenser where all

the exhaust steam is condensed in to the water by indirect cooling in the condenser.

Now turbine is rotating at the desired speed as it is directly coupled with the

generator and exciter. Generator generates AC current as per the manufacturer ‘s

recommended voltage. Now the power is available at the generator terminals & it can

be fed to substation. In the process Mechanical energy is converted into the electrical

energy.

Water

The water received from the river or any other water source is pumped to DM plant

and clarifier plant. In the DM plant water is purified to suit the Boiler. In Clarifier

plant, the water is purified to the desired extent and this water is used as the make

up to the small Induced draft Cooling Tower.

It is proposed to construct two nos. RCC stacks - One no. 220 meter height twin flue

for 2 x 150 MW Boiler & One no of 110 meters height for 50 MW boiler.

A brief review on pollution sources of respective production departments is discussed

below to identify the sources and the nature of environmental pollution in respect of

air, water, noise etc.

Raw Material Handling

In the raw material handling section the fugitive dust emissions arise from the

stockpiles of coal and other raw material handling units like crushing and screening

unit, material transfer points of conveyor system etc. Noise pollution may occur in

localized areas such as the crushing and screening unit.

Water pollution

In the proposed plant the major water pollution occurs in the wastewater generated from the DM plant and small quantity from cooling tower of the thermal power plant. Total 169 m3/hr waste water will be generated from plant and the same will be treated in Effluent Treatment Plant. The treated effluent will be utilized within the plant premises (Dust Suppuration for Road & Vehicle Washing, Ventilation, Coal Handling/Dust Suppuration, Greenbelt and Ash Handling etc.)

POLLUTION CONTROL MEASURES

The four principal pollutants in the plant are:

(i) Fugitive emissions of dusts in raw materials handling.

(ii) Air pollution due to stack emissions of combustion units

(iii) Waste water discharged from the various production units

(iv) Solid wastes generation. In each plant unit above, adequate

pollution control measures will be provided to meet the prevailing

emissions regulations and the allowable limits of waste water

discharge characteristics.



42

Some of the major pollution control measures which have been envisaged in

the proposed project are outlined below:

Air Pollution Control

i) Extensive dust extraction systems such as dust cyclones, bag

filters and electrostatic precipitators to arrest the dusts emissions

from the raw materials handling in power plant. The conveyors will

be closed as far as practicable.

ii) Stacks of appropriate heights based on proper dispersion of stack

emissions.

Water Pollution Control

In all other departments the cooling water will be re circulated, and the system

operated as zero discharge. While in the case of indirect cooling circuits,

there is no treatment required, in case of contaminated circuits it will be

necessary to have a treatment facility.

The drain water (storm water drainage) will be generally impounded in the

lower reaches of the plant for use inside the plant. This water will be used

for gardening, sanitary uses, sprinkling in dusty areas, road washing etc.

Noise Pollution Control

Noise pollution control measures will be provided in respective departments by

way of providing silencers, sound-proof cubicles / covers, and proper

selection of less noise prone plant and machineries.



43

Solid Waste Management

Ash is the main solid waste generated in the coal based thermal power plant.

The quantity of fly ash and bottom ash generated will be (0.84 MTPA) and

(0.21 MTPA) respectively.

Bottom ash will be disposed off by using slurry disposal system. Unutilized fly

ash will also be disposed off in designated ash disposal area. Fly ash will be

utilized in cement manufacturing, bricks plant and filling of mines etc.

Green Belt Department

It is proposed to have extensive green belts all around the plant by planting

suitable species of evergreen trees. Adequate tree plantations will substantially

abate the dust pollution, filter the polluted air, reduce the noise and

ameliorate the plant environment. Where tree plantations may not be feasible,

the unpaved land shall be covered with grass and small height bushes in order

to avoid soil erosion.

Workers Safety Measures

Besides the above, the operating and maintenance personnel will be provided

with all the necessary safety equipment such as hand gloves, gum boots,

aprons, helmets, protective glasses, ear muffs etc.

Workers training will focus on reduction of wastes, utilization of wastes and

generally maintaining a clean and healthy environment.

Pollution Monitoring

Necessary provisions for routine monitoring of stack emissions, ambient air

quality, noise level, water quality as required by the regulations will also be

provided.

pollution and the surrounding areas. The green belt helps to capture the fugitive

emissions and attenuate the noise apart from improving the aesthetics quality of the

region. A 20 – 25 m wide greenbelt shall be developed along the periphery of the plant

and in all open areas. Avenue plantation shall also be developed as per the standard

norms. Approximately 1500 trees per Ha will be planted in consultation with the local

Forest Department. 33% area of the total plant area will be developed as Green belt .

6.2 Social Infrastructure

For the social development company will provide the arrangement of community

hall, road, water, electricity etc. in the affected villages. For the economical

development the company will provide the employment as per requirement and

individuals qualification and eligibility. For the educational development the set up of

an English medium school is proposed.

For the social development in the affected area the company is planning to construct

community hall and will provide other facility like road, water, electricity etc.

6.3 Drinking Water Management

The source of water to the plant is Kelo river. The drinking water system will cater to

the drinking and sanitary requirements of plant personnel as well as laboratory and

contingent users. The required water will be withdrawn from the storage reservoir by

two pumps (including one stand-by). The treated water will be chlorinated and stored

in the overhead tank for distribution as drinking water.

6.4 Sewerage system

It is proposed to collect fecal sewerage through sewerage network from the

plant and lead it to the sewage treatment plant. The treatment plant shall

consist of screen grit separator, primary sedimentation tank, activated sludge

plant, secondary clarifier, sludge recirculation pump house etc. The treated



52

effluent quality shall conform to the Indian Standard for discharge to surface

water.

6.5 Industrial Waste Management

Management procedure and methodology of all kind of wastes from Plant like Ash

& Effluent Water etc is already discussed in details under point no. 3.9 of this

report.

6.6 Solid Waste Management

The main solid waste from the proposed Power Plant will be ash (Fly ash and Bottom

ash). The ash generation of about 3181 TPD(1.05 MTPA). Out of this, the bottom ash

will be about 20% of the total bottom ash generated i.e. 636 TPD (0.21MTPA ) and the

fly ash will be about 2545 TPD (0.84 MTPA ) . It is proposed to utilize 100% of the fly

ash generated. During emergency the ash will be disposed off safely in ash pond area

to avoid environmental hazards. All efforts, however, will be made to utilize fly ash for

various purposes. Unused fly ash will be disposed off in the ash pond. To control

fugitive dust emission from the ash pond area water sprinkling would be done. After

the ash pond is abandoned, its area will be reclaimed through tree plantation.

6.7 Power Requirement & Supply /Source

Power shall be required from CSEB during Construction of Power Plant and initial

start up of Plant. Once Plant is synchronized power will be flowing out from the plant.

Occasionally power will be required from the grid at the time of black of condition.

Total 15000 KVA connected demand is envisaged for plant.

CHAPTER-VIII

Project Schedule and Cost Estimates

8.1 Likely date of start of construction and likely date of completion

Phase I - Year March 2014 (2 x 150 MW) Phase II - Year June 2014 (1x50 MW)

PROJECT IMPLEMENTATION CONCEPT

In order to ensure coordinated implementation within the short construction

period envisaged for the project, it will be necessary to evolve an optimal

compromise between the fully disaggregated mode and the turnkey package

implementation mode. In principle, it will be prudent to tie up the technology

requirements and the key equipment in the production units to reliable and

high quality vendors. In the case of the major production packages, it will be

necessary for the Principal supplier (responsible for the basic engineering,

equipment engineering, technology, critical equipment supply, and

performance guarantees). The local procurement can cover the balance non-

critical equipment, auxiliaries and systems. The major auxiliary packages in

the power system, water system and the yard utilities will be formed into

discrete packages.

The proposed model has been adopted in a number of projects with

considerable success and fast ramp up. The construction schedule for the

project has been drawn up accordingly.

CONSTRUCTION SCHEDULE

Taking into account the estimated volume of work, the need to commission the

plant facilities in the shortest times with a rational planning of the production

facilities, a preliminary construction schedule for the proposed plant will be

prepared.

The commencement, duration and completion of the major construction

activities are given in this schedule. It will be noted that the schedule

envisages commissioning of the first unit of the plant in 27 month from ‘go-

ahead’ and the second unit 30 months.

ADVANCE ACTIONS

The project due to its large investment stands to gain substantially if the actual

construction and implementation period is kept to the minimum. For this purpose it



55

is necessary that the planning and preparatory work on the project be done in a

thorough manner, which will ensure that the project construction and

implementation once started can proceed uninterrupted and without any delays. The

start date (Zero date) for the construction schedule is reckoned as the completion of

these advance actions.

The advance actions on the project which will provide the appropriate foundation for

cost effective and timely implementation are:

i) Acquisition of land at the selected location

ii) Site survey and preliminary soil investigations

iii) Environmental clearance for implementation of the project

iv)Finalization of the financing arrangements for the project and the creation of a

project organization

v)Finalization of the adequate details of the project to enable site activities to

commence from the date of ‘go-ahead’.

vi) Issue of inquiries for the major packages and finalization of the orders for the

same

vii) Actions for linkages of power, water and other infrastructure.

SITE DEVELOPMENT & CONSTRUCTIONS FACILITIES

Site development activities include contour survey, soil investigation, site

preparation, site drainage, construction water, construction power, construction

storage yards etc. Activities related to site acquisition surveys and soil investigations

will envisage to be accomplished by the time the ‘go-ahead’ for project commences.

Establishment of construction power, water site preparation and other activities will

be completed in three (3) months from ‘go-ahead’.

Special efforts will have to be made during implementation to keep the earthwork and

the site preparation to the minimum both for cost savings as well as reduction in

construction time.

CIVIL & STRUCTURAL WORK

The schedule for carrying out the civil work and structural steel work is based on the

volume of work and interlink between the completions of some of these activities to

enable the subsequent activities to proceed. Structural steelwork covers all the

building structures. In order to meet the overall time-frame envisaged in the

schedule, the completion of civil and structural work in a time-bound manner is a

pre-requisite for the project completion for the schedule.



56

EQUIPMENT MANUFACTURE & DELIVERY

As indicated earlier, as an advance action, specifications will have to be issued for the

various plant and equipment, on a reputed manufacture / tenders basis and will be

evaluated and orders to be finalized. Major packages will cover material handling

system and Power plant, and these will need to be tendered out. Placement of order

for such packages is envisaged within two (2) months to (4) months from the date of

go ahead for project construction. It is assumed that advance work on the

preparation of specifications, evaluation of tenders and readiness for placement of

orders will be taken. The duration generally accepted internationally for manufacture

and delivery of various equipment have been taken into account while evolving the

implementation schedule.

The delivery schedule of equipment for power, water, utility and other auxiliary

systems has been so framed that they can be commissioned in time to cater to the

respective plant facilities for their commissioning.



57

EQUIPMENT ERECTION

Erection of equipment will have to commence after availability of fronts on completion

of the civil and structural work as well as delivery of equipment at the plant site. It is

expected that the duration for erection of equipment for plant facilities will vary

between (10) months and (16) months from the date of commencement of equipment

erection.

EXTERNAL FACILITIES

The various off site facilities such as external water supply, external power supply ,

road links etc will be implemented to suit the schedule envisaged. It is expected that

the above facilities will be ready well prior to commencement of trial runs and

commencement of the various plant facilities.

TRIAL RUNS & COMMISSIONING

A period of 2 months has been envisaged for carrying out trial runs.

PROJECT MONITORING

At the project implementation stage, all project activities from design and engineering

to construction, equipment supply, erection, testing and commissioning of the plant

and equipment will be monitored on the basis of a computerized network monitoring

system. Various reports as relevant for different aspects of project monitoring will be

generated through the computerized system.

Action points will be identified agency-wise and actions taken for timely

implementation the milestones to be achieved for meeting this schedule will be

identified and monitored for their achievement. Critical activities of the project as

they arise, will also be identified and monitored and followed up to ensure timely

completion.

CHAPTER-IX

Analysis of proposal (Final Recommendations)

9.1 Financial and social benefits with special emphasis on the benefits to the

local people including tribal population, if any, in the area

The proposed 350 MW Power plant will result in improvement of infrastructure as

well as upliftment of social structure in the area. The people residing in the nearby

areas will be benefited directly and indirectly. It is anticipated that the proposed

power plant will provide benefits for the locals in two phases i.e. during construction

phase as well as during operational stage of the plant.

• Construction Phase

Employment

The major benefit due to the proposed project will be in the sphere of

generating employment for about 700 persons in that area. The proposed

project will benefit local population.

• Operational Phase

Community Services

SEML will employ local people to the extent possible for avoiding creation of

additional infrastructure. SEML will develop medical facilities for catering to

the needs of the project personnel. These facilities will also be extended to the

local community in due course.

Education

SEML will initiate action for social up liftment in the area like female education,

vocational training. Financial support will also be extended to strength education

infrastructure in the region.

Employment

The manpower requirements for the operational phase of the Power Plant will be

about 700 people. In addition, there will be an indirect employment for skilled/ semi

skilled people during project life. All attempts will be made to employ suitable, locally

available, skilled personnel from the study area. In case of non-availability of skilled

persons, people will be employed from out side the study area.



60

Transportation

There will also be small increase in the vehicular traffic due to passenger transport.

This increase in traffic will not have any consequence to warrant special mention.

One should expect that the increased passenger load in the sector would prompt the

state government/ private movers to start new and frequent public transport services

to this area, bringing up liftment to the whole locality.

Other Benefits

SEML is equally conscious for the all round socio-economic development and is

committed to raise the quality of life and social well being of communities where it

operates. Its CSR initiatives have been prioritized on local needs, which focus on

Health, Education, Infrastructure Development and Environment Conservation.
