2. INTRODUCTION OF THE PROJECT/BACKGROUND INFORMATION

2.1 Identification of Project and Project Proponent

The Singareni Collieries Company Limited (SCCL) is a Government Company jointly owned by the Government of Telangana and Government of India on a 51:49 equity basis. The Singareni coal reserves stretch across 350 km of the Pranahita – Godavari valley of Telangana with a proven geological reserves aggregating to 8791 MT The studies of Geological Survey of India attribute as much as 22207 million tonnes of coal reserves in the Godavari valley coalfield. The inventory covers up to a depth of 1200 meters and it includes reserves proved, indicated as well as inferred. The SCCL has been exploiting coal for more than 127 years the Company had expanded its mining activities in Mancherial, Komaram Bheem Asifabad, Peddapalli, Jayashankar Bhoopalpalli, Bhadradri Kothagudem and Khammam districts of Telangana. The coal produced by SCCL in the Godavari valley coalfield in the year 2016-17 was 61.34 Million tonnes. The targeted production for the year 2017-18 is 66.06 Million tonnes.

SCCL also operating small captive power plants since 1960 and recently SCCL is foraying into large scale power generation. SCCL constructed Non pithead power station of 2x600 MW units located at Pegadapalli village, Jaipur Mandal in Mancherial district of Telangana which is commisioned in the year 2016.

The Environmental Clearance was accorded by Ministry of Environment, Forest and Climate Change vide Lr. No. J-13012/88/2008-IA.II (T), dated 27.12.2010 and Consent for Establishment (CFE) under Air (Prevention & Control of Pollution) Act and Water (Prevention & Control of Pollution) Act by State Pollution Control Board vide Order No. 64/PCB/CFE/RO-NZB/HO/2010-818, dated 16.06.2011 and Consent For Operation (CFO) under Air (Prevention & Control of Pollution) Act and Water (Prevention & Control of Pollution) Act by State Pollution Control Board vide Order No. TSPCB/CFO/NZBG/HO/2017-42,Dt.04.04.2017 and valid up to 30.04.2022 under Auto Renewal for the 2x600 MW Thermal Power Plant which is under Operation. In view of the power crisis in the newly formed state of Telangana, State Government vide letter dated 16.03.2017 accorded approval for setting up 1x800 MW as expansion and directed the SCCL to establish one more unit of 1x800 MW in addition to 2x600 MW Thermal Power Plant.((From 1200 MW to 2000 MW by adding 1x800 MW)

As SCCL is already constructed 2x600 MW units and are in operation, some of the BOP facilities of these units have spare capacities which can be utilized for the proposed 1X800 MW unit. The review of existing system reveals their adequacy for the proposed additional unit. The spare capacities of the existing system have been worked out after meeting the requirements for the 2x600 MW units in operation.

Infrastructure facilities such as land, water transport arrangements, railway line, roads etc. are available. The advantages of proposing the additional unit at same location are:

No new infrastructure facilities are required for expansion unit. Total required land is available with SCCL. No Re-settlement is involved. Availability of adequate raw water from Pranahita River. Water will be pumped through the existing pipe line and pump house. There is no forest land involved for the project. Since existing facilities are being used, cost of the power would be less.

2.3 NEED FOR THE PROJECT AND ITS IMPORTANCE TO THE COUNTRY AND OR REGION

POWER SCENARIO OF TELANGANA STATE - POWER SUPPLY SCENARIO

As per the report “Power for All – Telangana State” A joint initiative of Govt. of India and Govt. of Telangana State, energy deficit in Telangana for last year’s was in the range of 4%-12%. Energy requirement in Telangana was 50,916 MU in FY 14-15, of which only 2,128 MU could not be met resulting in an energy deficit of nearly 4.2% with a maximum historic peak demand of 8,331 MW in 2014-15.

As can be seen from the table below, peak demand has increased by over 2,588 MW

during the period FY 2008-09 till FY 2014-15 as against which peak met has increased by 1,345 MW.

There was a 11% increase in the peak deficit in FY 2014-15 over FY 2013-14 attributable to the increased agricultural loads whereas the energy deficit has decreased by 1% attributable to the extensive short term market purchases which contributed to 21% of the total power purchased in FY 2014-15.

Implementation of 24X7 supply across the State is likely to increase the electricity consumption substantially. Various factors that have been considered for future energy projections include:

Demand from Domestic segment

Agriculture supply from 7 hours to 9 hours in a day

Implementation of Lift Irrigation Schemes

Urban development in cities of Hyderabad, Warangal, Nizamabad and Karimnagar.

Upcoming major projects such as Hyderabad Metro Rail, Hyderabad ITIR region

Upcoming Bayyaram Steel Plant.

Existing Generation Capacity

Energy availability from existing sources as on FY 2014-15 was about 48,788 MU inclusive of market purchases and coal based power from long-term sources constituted nearly 66% of energy availability.

PPAs due to expire in the next 5 years

Some of the existing PPAs of TSDISCOMS with generators would expire during the next 10 years. Currently, Telangana is entitled to 53.89% of power from TSGENCO and APGENCO stations. Post expiry of PPA, no capacity would be available from APGENCO stations while 100% capacity of TSGENCO plants would be available to Telangana. This project (Singareni TPP Stage-II) has already been identified in the referred report while calculating the generation capacity and meeting the required supply of power against the demand to energize the power thirsty & development oriented newly formed Telangana State.

Considering above facts & data, it is prudent to go for a coal based supercritical unit of 1X800MW utilizing the space available and the facilities of Stage-I.

2.5 Imports Vs Indigenous Production

The entire saleable power from the project will be procured by TSTRANSCO independent consumers by utilizing the 400 kV power transmission grids being managed by TSTRANSCO. The saleable power from the additional unit will be of the order of 754 MW after accounting for



8

auxiliary power consumption of 5.75%.The total salable power from the entire 2X600 MW &1X800 MW will be 1885 MW to the TSTRANSCO.

3.4 Project Description with process details

The proposed 1x800 MW Coal Based Thermal Power Plant of STPP, Stage-II is super-critical pulverised boiler technology. Coal received from the mines (expected bridge linkage from SCCL mines) at -200 mm size is crushed in the crusher house to -20mm size, which is subsequently pulverized in the coal mill. The powdered coal is burnt in the furnace to generate steam in the boiler. The steam generated in the boiler is expanded in the HP, IP & LP turbines and power is generated in the generator. The steam after expansion in the turbine is condensed in the condenser and the condensed steam is circulated back to the boiler. The hot gasses from the furnace after losing heat in different areas goes through the Electrostatic Precipitators, where ash is collected. The clean gas goes through the chimney. The bottom ash from boiler is collected in hydro-bins where water is separated and Ash in dry form is sent to underground mines of SCCL. The separated water will be reused / recirculated in the system.

On the other hand, the proposed project is likely to have several benefits like improvement in indirect employment generation and economic growth of the area, by way of improved infrastructure facilities and better socio-economic conditions.

5 Planning Brief

5.1 Planning Concept

As SCCL is already constructed 2x600 MW units and in operation, existing infrastructure facilities such as land, water transport arrangements, railway line, roads etc. will be used.

No new infrastructure facilities are required for expansion unit.

Total required land is under possession of SCCL, No R&R is involved.

Availability of adequate raw water will be met from Pranahita River.

Water will be pumped through the existing pipe line and pump house.

There is no forest land involved for the project.

Since existing facilities are being used, cost of the power would be less.

5.2 Population Projection

Around 450 people would be required to operate and maintain the 1X800 MW in addition to 1100 People required for 2x600 MW power plant under construction. During the construction stage about 2000 to 3000 people required for various works of construction. It is expected that a fair percentage of skilled and unskilled personnel would be available from the nearby areas for operation and maintenance. In addition to the operational, maintenance and construction personnel, there will be indirect employment creation in the area through service sectors, material supply, establishment of ancillary units, transport, etc.

5.3 Land use planning (Breakup along with green belt etc.) Land use planning of proposed expansion of 2x600 MW to 2000 MW by expansion of another 1X800 MW is as follows:

5.4 Assessment of Infrastructure Demand (Physical & Social) Power is an essential requirement for all facets of our life and has been recognized as a basic human need. It is the critical infrastructure on which the socio-economic development of the country depends. India faces formidable challenges in meeting its energy needs and providing adequate energy of desired quality forms to various users in a sustainable manner and at reasonable cost. The gap between availability of power and the demand is not likely to be met in the foreseeable future either in southern region or in state of Telangana. To meet the deficit power in newly formed Telangana state, the Singareni Collieries Company Limited (SCCL) (Which is a Government Coal Mining company jointly owned by the Government of Telangana and Government of India) has proposed to install one unit of 800MW at their existing 2x600 MW STPP at Jaipur Mandal, Mancherial District. Accordingly, the proposal of Singareni Collieries Company Limited, for expansion of unit of 800 MW will further help in meeting the shortfall in generating capacity in the Telangana State.

5.5 Amenities/ Facilities The main approach roads to the plant have already been constructed for the operating units. The approach roads for the proposed expansion unit have to be constructed and the drainage system for the proposed unit shall be constructed separately. The route of the existing Nallah has to be diverted which is currently passing though the BTG area of the proposed unit. Necessary approval from competent authority has already been obtained for diversion of existing Nallah. Additional quarters shall be constructed in existing township area to accommodate the plant personnel of proposed unit.

6 Proposed Infrastructure The proposed infrastructure are main plant building, boiler, transformer bay, switchyard, chimney, coal handling system, water system, Induced draught cooling towers, miscellaneous building like control room, diesel generator building, water treatment plant etc

6.1. Industrial Area (Processing Area) The plant layout of the proposed thermal power plant is enclosed.

9 Analysis of proposal (Final Recommendations)

9.1 Project cost estimates and financial analysis

For additional 1x800MW

The objective of this section is to estimate and analyze the project cost, cost of generation and Levelised tariff for the proposed project in order to assess overall financial viability of the project.

Basis of cost estimates

The project cost estimate for the proposed power plant has been worked out on the following basis;

i. Unit size considered is 800 MW for financial analysis. Commissioning of the project is considered as 50 months from zero date.

ii. Various items of packages covered in the cost estimates are based on most of the packages are based on the awarded rates for various ongoing projects of NTPC and suitably updated to current price level.

iii. The cost of Balance of Plant (BoP) and other equipment has been estimated based on preliminary design and on the benchmark cost of the similar projects.

iv. The project is financed through domestic funding. Taxes and duties on supply of equipment, civil works, contract and erection and commissioning have been worked out as per the prevalent rates. The economic plant life has been taken as 25 years for depreciation calculation as per CERC norms.

As per the above report, the overall peak demand shortage during 2014-15 in the newly formed state Telangana is 4.2%.

Conclusion As seen from the above, the gap between availability of power and the demand is not

likely to be met in the foreseeable future either in Southern region or in Telangana. All out efforts are called for to add capacity considering the fuel availability and evacuation system. Accordingly, the proposal of Singareni Collieries Company Limited, for extension of unit of 800 MW will further help in meeting the shortfall in generating capacity in the Telangana State.

9.2 Financial and social benefits (With special emphasis on the benefit to the local people

including tribal population, if any, in the area)

Financial

For proposed additional 1x800MW During construction phase of the project, the project proponent shall incur approximately Rs. 15.0 Crores on CSR activities. Further during the operation phase of the project, the CSR will be as per the relevant directives in this regard.

Social benefits The project will improve the socio-economic status of the society in the region by generating direct and indirect employment opportunities The project will contribute additional revenue to the State & Central exchequers in the form of taxes and cess etc.

The anticipated impacts of the project are explained below: Human settlement is expected to increase after this project gets operational. In the long term, the project will have impact on the population growth due to migration of people from outside area. Indirect employment opportunities will also add to this. The literacy level of the project area is



25

likely to increase as there will be influx of many educated people taking up jobs in the project, which is likely to result in establishment of better educational facilities. The project related construction activities will benefit the local populace in a number of ways such as supply of construction laborers – skilled, semi-skilled and un-skilled, tertiary sector employment and provision of goods and services for daily needs including transport. The proposed project will provide employment to the skilled as well as un-skilled persons. The local population will be given preference depending upon their suitability to the job requirement. Besides direct employment, indirect employment opportunities will also open up. The project will have positive impact in the region. Quality of life of the people will improve, which in-turn will improve the socio-economic conditions of the area.
