2.3 Need for the Project & Its Importance to the Country & Region Power is one of the key infrastructural elements for the economic growth of a country. Proposed Katwa STPP is envisaged as a base load station to meet the power demand of West Bengal and other States in Eastern Region. The project is expected to start yielding benefits during early 13th Plan period.

2.4 Demand Supply Gap Demand & Supply Scenario at the end of 12th Plan taking into account the addition of 86500 MW has been worked out based on the 17th Electrical Power Survey is presented:

2.8 Employment Generation (Direct & Indirect) due to the Project The project will generate direct and indirect employment opportunities as well as opportunities for self-employment. Power projects have mechanised and automated plants. Therefore, the direct opportunities for employment during operation phase are limited. The estimated no. of employees during operation phase of the project is estimated to be about 650. However, during construction phase, the total no. of workers likely to be employed will be much higher (about 2,000). In addition to the people directly involved in construction and operation of the power project, employment opportunities in subsidiary industries and service sectors as well as self employment opportunities shall also be generated.

3.0 Project Description: 3.1 Type of Project, Interlinked Project & Interdependent Project

Katwa STPP shall be a pulverised coal fired thermal power project based on super critical boiler parameters. There are no other projects interlinked/ interdependent to Katwa STPP.

3.3 Details of Alternate Sites Katwa STPP (2x600 MW) was originally conceived by M/s West Bengal Power Development Corporation Limited (WBPDCL). Env. Clearance (EC) for 2x600 MW capacity and TOR for 2x800 MW capacity were accorded by MOEF to WBPDCL vide letter dated 01.05.2008 and 13.05.2011 respectively for the same site.

Subsequent to accord of environmental clearance, WBPDCL started various activities related to land acquisition, construction of boundary wall and office complex etc. and incurred an expenditure of Rs. 180 Crores on construction till 18.04.2012. On 27.02.2014, the project was transferred to NTPC and the capacity was changed by NTPC as 2x660 MW.

Alternate sites were not explored due to the following reasons:

EC for 2x600 MW capacity and TOR for 2x800 MW capacity were already accorded by MOEF for the same site and there is no change in location of the project.

Significant portion of land (556 acres out of 911 acres) have already been acquired and the construction had already started.

3.4 Size & Magnitude of Operation The capacity of power project would be 1320 MW. It will consume about 6.46 Million Tonnes of Coal per annum (considering a GCV of 4150 kcal/kg and 100% PLF) and 4100 m3/hr of water. The project will operate round the clock in three shifts of operation. The project will have a dedicated township, housing about 3000 population.

3.5 Project Description & Process Details

In a thermal power plant, the chemical energy of the fuel (coal) is first converted into thermal energy (during combustion), which is then converted into mechanical energy (through a turbine) and finally into electrical energy (through a generator). The schematic diagram of the process of power generation a coal based thermal power plant is shown in Exhibit II. It has the following steps.

(1) The coal is transferred from the coal handling plant by conveyor belt to the coal bunkers, from where it is fed to the pulverizing mills, which grind it to fine powder. The finely powdered coal, mixed with air is then blown into the boiler by a fan where it burns like a gas.

(2) The process of combustion releases thermal energy from coal. The boiler walls are lined with boiler tubes containing high quality demineralized water (known as boiler feed water). The combustion heat is absorbed by the boiler tubes and the heat converts the boiler feed water into steam at high pressure and temperature. The steam, discharged through nozzles on the turbine blades, makes the turbine to rotate, which in turn rotates the generator coupled to the end of the turbine. Rotation of generator produces electricity, which is passed to the step-up transformer to increase its voltage so that it can be transmitted efficiently. The power is evacuated via switchyard through a Transmission System.

(3) During combustion, the non-combustible part of coal is converted into ash. A small part of ash (about 20%) binds together to form lumps, which fall into the ash pits at the bottom of the furnace. This part of ash, known as bottom ash is water quenched, ground and then conveyed to pits for subsequent disposal to ash disposal area or sale.

(4) Major part of the ash (about 80%) is in fine powder form, known as Fly Ash, and is carried out of the boiler along with the flue gas. The flue gas, after heat recovery, is passed through the electrostatic precipitators, where the ash is trapped by electrodes charged with high voltage electricity.

(5) The flue gases exiting from the Electrostatic Precipitators (ESPs) are discharged through a tall chimney for wider dispersal of remaining ash particles and gases. The ash collected in the ESP hoppers is extracted in dry form and conveyed to dry ash storage silos from where it is supplied to user industries.

(6) Unused part of fly ash is mixed with water and conveyed to ash disposal area in a slurry form. Ash can also be lifted from ash disposal areas for utilization.

(7) The steam, after passing through the turbines, is condensed back into water in condensers and the same is re-used as a boiler feed water for making steam. The reasons for condensing and reusing the steam are following: -

The cost of boiler feed water is very high as it is very pure demineralised water hence reuse is economical.

The use of condenser lowers the temperature at the exit end and hence increases the efficiency of the turbine.

(8) The condenser contains tubes through which cold water is constantly pumped. The steam passing around the tubes of condenser looses heat and condenses as water. During this process, the steam gets cooled while cooling water gets heated up (by about 10oC). This hot water is cooled in a cooling tower and recycled for cooling. However, in order to control dissolved solids, a certain amount of blow down is required from the cooling towers, which is used in the plant for other usages such as service water, coal dust suppression etc.

3.6 Requirement of Raw Materials

Coal and Water are the main raw materials proposed to be used in Katwa STPP for power generation. Commitment for supply of coal vide WBPDCL’s letter dated 11.02.2014 for Katwa STPP from the total pool of coal sources of WBPDCL and receivables from CIL (initially) till coal from Deocha-Pachami Captive Coal Block of WBPDCL is available. Ministry of Shipping, Road Transport and Highways has given commitment for 42 cusecs of water to Katwa STPP vide letter dated 23.10.2006 and NOC from Govt. of West Bengal is available vide letter dated 28.05.2007.

In addition, Heavy Furnace Oil/ HPS/ LSHS shall be used during start-up, warm up and low load (up to 30%) operations. Light Diesel Oil (LDO) firing shall be used to facilitate cold start-up of the unit when no auxiliary steam is available for HFO heating and atomization.

3.7 Resource Optimization, Recycle & Reuse Coal, Water and Land are the three main natural resources required for setting up of Katwa STPP. With extensive experience in thermal power generation, NTPC shall make the best efforts to optimize the utilization of resources.

Katwa STPP shall be based on super critical boiler parameters, which has higher thermal efficiency as compared to conventional pulverised coal fired units based on sub-critical boiler parameters. The increase in efficiency results in lower coal consumption as well as lower generation of ash and gaseous emissions per unit of electricity generated. NTPC shall make maximum efforts to utilize the ash generated from the project.

While developing the details of water system for the project utmost care shall be taken to minimize water requirement as well as effluent generation. Main features of the water system shall include:

• Recirculating type C.W. system with cooling towers.

• Utilisation of Cooling Tower blow down for Coal dust suppression and extraction system, Service water system, Ash handling and Fire fighting

• Recycle and reuse of effluents from coal dust suppression and extraction system and service water system

• Ash water recirculation system. • Recirculation of filter backwash to clarifier inlet.

3.8 Availability of Water & Power

The water requirement is estimated to be about 4100 m3/hr, which is proposed to be drawn from Bhagirathi river.

Ministry of Shipping, Road Transport and Highways has given commitment for 42 cusecs of water to Katwa STPP vide letter dated 23.10.2006 and NOC from Govt. of West Bengal is available vide letter dated 28.05.2007. Katwa STPP itself is a power generating project, hence there will be no long term requirement of power from external source. The requirements of the construction power supply for the project would be met from 33kV Katwa substation of WBSEDCL (Approx 7-8 Kms. from proposed site) through two (02) nos. of 33 kV lines. Necessary 33/11 kV substation along with 11 kV ring main/LT sub-stations shall be provided for the required power plant area.

3.9 Quantity of Wastes to be Generated The wastes generated in a coal based power station consist of flue gas and ash generated due to combustion of coal and liquid effluents generated due to cooling, various industrial processes and domestic use of water.

Ash generated due to combustion of coal will be the main industrial/ solid waste generated from the project. About 80% of the ash shall be generated as Fly Ash while 20% of the ash shall be generated as bottom ash. With average annual coal requirement of 6.46 MTPA and average 40% ash in coal, it is estimated that about 2.9 million tones of ash shall be generated annually. The project will have effluent treatment plant and various systems for recycle and reuse of treated effluents. During normal course of operation the entire quantity of main plant effluents generated shall be treated, recycled and reused within the plant area for various purposes. Treated sanitary waste from sewage treatment plant shall also be used for green belt development/ horticulture/ dust suppression, to the extent possible. However, during the periods of low demand, specially heavy monsoons, when the demand of water as well as evaporation losses are low, the discharge of treated effluents outside the plant premises can not be avoided.

The levels of the natural ground vary between RL (+) 16.00M to RL (+) 21.00M. Most of the land proposed to be acquired is private agricultural land while a small portion (130 acres out of 911 acres) is government land. There are no homesteads proposed to be acquired.

4.3 Existing Infrastructure/ social infrastructure A detailed analysis of social infrastructure available at site shall be undertaken during EIA Study. However, as the proposed site is located near Katwa Sub-division Headquarter in Bardhaman district, the social infrastructure available is of moderate level.

4.4 Soil Classification The soil of Bardhaman district have been formed and enriched by the silt deposition of the river Ganga, Damodar, Ajay, Barakar, Khari, Banka and other small rivulets. There are 3 types of soil in the district;

i. Gangetic Alluvium: This type of soil is found in this district along with river Ganges. This is predominant in Katwa and Kalna subdivisions.

ii. Vindhya Alluvium: This alluvium soil is found between the rivers Ajoy and Damodar. This is created due to silt deposition of these two rivers.

iii. Lateritic & Gravelly Soil: It is found in the Western part of the district which is highly porous and acidic in nature and deficient in organic matter. This soil is prone to erosion.

The soils found in the Katwa region are pre-dominantly Clay loam to Sandy Loam and Loamy (about 48 – 60%) and slightly acidic to acidic in nature.

4.5 Climatic Data The weather and climate of the region are similar to the rest of Gangetic West Bengal, with three main seasons (summer, rainy, and winter) and two more barely discernible seasons - autumn and spring. The climate of the area is humid and tropical. It is characterized by a hot and dry summer from March to May, a monsoon or rainy season from June to September and a cool pleasant winter from October to February. In winter there is much more rainfall in Katwa than in summer. The average annual temperature in Katwa is around 26.4 °C. About 1331 mm of precipitation falls

5.0 Planning Brief

5.1 Planning Concept As discussed in Para 2.4 above, the planning of power projects is based on demand & supply scenario of the country/ region, which is based on Electrical Power Survey conducted by CEA. Once the necessity of the project, based on demand and supply gap is established, the site for project is selected based on the following considerations:

i. Availability of suitable and adequate land ii. Availability of reliable source of water

iii. Distance from source of coal iv. Road and railway access v. Availability of infrastructural facilities

vi. Conformity of Environmental Guidelines

5.2 Population Projection Power projects are highly mechanised and automated plants. Therefore, the direct opportunities for employment during operation phase are limited. The estimated no. of employees during operation phase of the project is estimated to be about 650. Considering the staff of CISF and support services, it is estimated that about 750 families will reside in the project township during operation stage. However, during construction stage, the number of workers will be much higher (about 2000). Temporary labour colonies with amenities like water supply and sanitation facilities shall be developed for the construction phase.

5.3 Land Use Planning The land acquired for the project shall be mainly used for establishing main power house complex, township and ash disposal area. These facilities are described in Section 6.0. A green belt of 100 m width shall be planned all around main plant area except the switch yard site. In addition, large scale afforestation and plantation activities shall also be undertaken in and around main plant and township areas at all available spaces.

5.4 Assessment of Infrastructure Demand and Amenities/ Facilities Planned The area possesses moderate level of infrastructural facilities. However, the township shall be provided with various amenities/ facilities like Hospital (general hospital with support facilities), Pre-Nursery / Nursery School, Higher Secondary School, Bank, Post Office, Telephone Exchange, Shopping Centre, Transport Centre, Petrol Pump, Community Center/ Club/ Welfare Association, Bal Bhawan, Sports Complex, Auditorium, etc. Therefore, there will be no stress on the existing amenities/ facilities in the area.
