8 Drivers For Ultra Mega Power Projects LARGE CAPACITY ADDITION PLANNED OVER NEXT DECADE IN 11 TH PLAN BEYOND PACE OF THERMAL CAPACITY ADDITION TO INCREASE FROM ~ 5000 MW/Yr TO ~ 10,000 MW/Yr ADVANCED PROVEN TECHNOLOGY WITH HIGH EFFICIENCY FOR OPTIMAL USE OF RESOURCES – HIGHER EFFICIENCY ECOFRIENDLY POWER GENERATION ECONOMY OF SCALE OPERATIONAL FLEXIBILITY( Faster Start Up, Load Cycling)

9 Concept Of Ultra Mega Power Project A FEW PRE-IDENTIFIED PROJECTS EACH WITH A CAPACITY OF ABOUT 4000 MW ENVISAGED– ABOUT 7 NOS. AT PRESENT –SASAN, MPPIT HEAD –AKALTARA, CHATTISGARH –MUNDRA, GUJARAT –GIRYE, MAHARASTHRACOASTAL –TADRI, KARNATAKA –ORISSA – PITHEADUNDER –ANDHRA PRADESH - COASTAL CONSIDERATION USE OF LARGE UNIT SIZES OF 600 MW & ABOVE SUPERCRITICAL TECHNOLOGY FIRST FIVE TARGETTED FOR FINALISATION BY 31 ST DEC. 2006 PIT HEAD STATIONS WOULD HAVE COAL BLOCKS ALLOCATED WITH CAPTIVE MINING

10 Road Map For Implementation Of Ultra Mega Power Projects POTENTIAL SITES IDENTIFICATION AND SELECTION BY CEA THROUGH SATELLITE IMAGING, VISITS AND INTEGRATION WITH STATE AND LOCAL AGENCIES. SEPARATE SPV FOR EACH PROJECT FOR PROJECT DEVELOPMENT. PFC IDENTIFIED AS NODAL AGENCY FOR SETTING UP OF SHELL COMPANIES. -------- CONTD.

11 SHELL COMPANIES TO TAKE FOLLOWING ACTION -PREPARATION OF PROJECT REPORT -INITIAL LAND ACQUISITION -COAL LINKAGES/COAL BLOCKS ALLOCATIONS FOR PIT HEAD PROJECTS -ALLOCATION OF WATER SHELL COMPANIES TO APPOINT CONSULTANTS FOR ICB BID DOCUMENT PREPARATION & EVALUATION. SELECTION OF DEVELOPER THROUGH TARIFF BASED ICB. SHELL COMPANIES THEN TO BE TRANSFERRED TO THE SUCCESSFUL BIDDER FOR PROJECT EXECUTION.

12 Formation Of Shell Companies FIVE SPV (SHELL COMPANIES) FORMED ARE : 1.SASAN POWER LIMITED (M.P.) 2.COASTAL GUJARAT POWER LIMITED (MUNDRA PORT) 3.COASTAL MAHARASHTRA MEGA POWER LIMITED. 4.COASTAL KARNATAKA POWER LIMITED. 5.AKALTARA POWER LIMITED (CHATTISGARH) STATE GOVTS. HAVE BEEN REQUESTED BY MOP TO PROVIDE NECESSARY SUPPORT. MINISTRY OF COAL HAS AGREED IN-PRINCIPLE TO ALLOCATE COAL BLOCKS, FOR PITHEAD STATIONS. ADDITIONAL PIT HEAD SITE IN ORISSA AND COASTAL IN ANDHRA PRADESH BEING EXPLORED.

13 Current Status Of Ultra Mega Projects. FIVE SHELL COMPANIES FORMED. EOI ISSUED FOR SADAV, MUNDRA, GIRYE & TADRI. TECHNICAL CONSULTANTS APPOINTED BY SHELL COS. FOR PREPARATION OF PROJECT REPORTS. CONSULTANT APPOINTED FOR BID DOCUMENTS AND BIDDING PROCESS. POWER ALLOCATION/POWER PURCHASE AGREEMENTS ARE BEING FINALISED.

14 Use Of Super Critical Technology Supercritical Technology is widely established and accepted with more than 500 units in operation. Widely prevalent cycle parameters: –Pressure: 246 -250 kg/cm 2 –Temperature:538/538 deg C »538/566 deg C (Sipat & Barh TPS) »566/593 deg C (Mainly in Japan & Germany) »593/593 or 600/600 deg C Preferred steam parameters include higher steam temp. of 566 to 593 deg C depending upon site specific techno-economics. BHEL collaboration includes these parameters. Contd.

18 Option of using Washed Coal Indigenous coal generally have high ash content, wide variation in calorific value, presence of extranous matter and is unsized. Considering large unit size, it is desirable to have good and consistent coal quality, free of extraneous matter with a view to –Narrow down coal design range –Less wear and tear of coal handling and coal pulverizers –Reduced teething problems in initial stage of technology introduction –Comfort in plant operation

19 CONCLUSION A MAJOR SHARE OF CAPACITY ADDITION EXPECTED THROUGH LARGE SUPERCRITICAL UNITS IN ULTRA MEGA PROJECTS AND OTHER 800 MW SIZE UNITS BY NTPC, APGENCO & OTHER UTILITIES. HIGHER STEAM PARAMETERS IN SUPERCRITICAL UNITS PREFERRED FOR BETTER EFFICIENCY. FOR OVERALL ECONOMICS, PITHEAD STATIONS CAN BE INTEGRATED WITH COAL WASHING AND CFBC UNIT TO USE WASHERY REJECTS. DESIRABLE TO HAVE TECHNOLOGY TRANSFER WITH INDIGENOUS MANUFACTURING CAPACITY BUILDING TO MEET THE PROJECTED CAPACITY ADDITION TARGETS WITH ADEQUATE COMPETITION.
