Drivers For Ultra Mega
Power Projects
 LARGE CAPACITY ADDITION PLANNED OVER
NEXT DECADE IN 11TH PLAN BEYOND
 PACE OF THERMAL CAPACITY ADDITION TO

 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)

UNDER
CONSIDERATION
• USE OF LARGE UNIT SIZES OF 600 MW & ABOVE
SUPERCRITICAL TECHNOLOGY
• FIRST FIVE TARGETTED FOR FINALISATION BY 31ST DEC.
2006
• PIT HEAD STATIONS WOULD HAVE COAL BLOCKS
ALLOCATED WITH CAPTIVE MINING
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.
• 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.
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.
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.
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/cm2
– 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.

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
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.
