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.

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

auxiliary power consumption of 5.75%.The total salable power from the entire 2X600 MW &1X800 MW will be 1885 MW to the TSTRANSCO.
Indigenous production of the power will be much cheaper, reliable and comfort than the import of the power from other states, The proponent is operating number of coal mines in the area of power plant there will not be any problem of supply of coal to the power plant.
2.6 Employment Generation (Direct & Indirect) due to the Project
During the construction period the requirement of manpower will be about 2000 to 3000 persons on temporary basis. During Operational phase, direct employment for 1550 persons (1100 for 2x600 MW and 450 for additional 1X800 MW) will get and about 1000 persons will get indirect employment.

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.

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.

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
