OVERVIEW
Indian Energy Scenario
India is one of the fastest growingeconomies of the world today with an ever-rising energy requirement, needed to sustainits momentum of growth and enable its
emergence on the global platform. Itsenergy requirement has almost doubled inthe past decade and it exhibits no signs ofthis trend reversing in the coming decades.
Source: Infraline
The installed power generation capacity ofIndia stands above 1,51,070 MW, yet thepower deficit continues being very high.
According to CEA reports, the power deficitfor the month of July, 2009 was 12,983 MW(11.3% of the overall requirement).
For an economy on the path ofdevelopment, reducing consumption alone isnot a feasible solution especially when theper capita consumption is deplorably low at704 kWh
1, less than one third of the World
average.
Hence, increasing present generationcapacity as quickly as possible through rapidcapacity addition is the only solution forbridging this demand and supply gap.

Capacity Addition in India
The Government is making continuousefforts to meet the growing requirement forpower through capacity additions. Each fiveyear plan foresees achievement of a setlevel of capacity addition. These targets areset by fuel source for central, state andprivate sectors. Presently coal is thedominant fuel source and central sector hasmade the maximum contribution to the
capacity addition.
Over the past, the government has oftenfailed to achieve the targets fixed for theseplans. The 10
thPlan (2002-07) is one such
case in point where only 21,000 MW out of atarget of about 41,000 mw additionalcapacity was achieved.

In the ongoing 11th Plan which is ending onMarch 31, 2012, only 19,000 MW (24%) ofthe capacity addition target of 78,700 MWhas been added despite the plan havingcrossed the half way mark on November2009.
The analysis of this lacklustre performanceduring the 10
th plan indicates that the
domestic equipment manufacturers cannothandle a capacity of more than 20,000 MWin a five year period. This inadequacy ofproduction capacity was found to be themajor reason for delay and hence shortfall incapacity addition. Though BHEL, theprimary domestic power equipmentmanufacturer, is in the process ofaugmenting its capacity to about 10,000 MWper annum (of which a capacity base of8,000 MW per year was achieved in thebeginning of 2008), it alone cannot bridgethe gap. A lot more is required to be done inthis regard.
The way forward
The Indian Power Generation sector isplagued by two major problems- slow paceof capacity addition and inefficientgenerating units. The first can be attributedto inadequate equipment manufacturingcapacity in the country and problems in
securing fuel supply and the second to highash content of domestic coal which is thedominant fuel source in the present fuel mixfor power generation and use of sub criticaltechnology which is a relatively inefficienttechnology.
Incremental capacity is crucial to Indiasdevelopment plan and hence the obstaclesin achieving the desired performance needto be overcome. Capacity additions throughprogressively larger generation units whichwould help attain economies of scale and
time, and use of more efficient technologieslike supercritical technology is the only wayforward. This has been recognized by theGovernment as well and is reflected by itsplans for manufacturing indigenoussupercritical technology and developingUltra Mega Power Plants for introducing thesame.
Supercritical Technology
Coal having a contribution of over 50% inthe total installed capacity of India and over80% in the actual generation, assumes avery important role in Indian power sector.
Though coal is Indias most abundant fuelresource, its reserves are limited. To usethis resource most wisely and to reduce CO2emissions which cause global warming,technology enabling higher generatingefficiency is required. Supercriticaltechnology is one such technology.
Supercritical (SC) power plants operate attemperatures and pressures above thecritical point of water, i.e. above thetemperature (373 Deg C) and pressure(225 kg/cm
2) at which the liquid and gas
phases of water coexist in equilibrium, atwhich point there is no difference betweenwater gas and liquid water. This results inhigher efficiencies.
The efficiency of supercritical units rangesfrom 37-40% depending on design,operating parameters and coal type which ismore efficient than sub critical by about 2-3percentage points. For a typical 700 MWplant, one percentage point efficiency gainresults in reduction of 2.4% in fuelconsumption implying a substantial
reduction in fuel costs, quantity used andCO2emissions over a 30 year period.
Presently all the coal based units operatingin the country are based on sub-criticaltechnology. It has been projected that byconstructing power plants based on supercritical units, CO2 emissions could bereduced significantly by 2025.
Purpose of this Paper
Supercritical technology is being inducted inthe country through a number ofsupercritical units that are underconstruction. In 2008, the Government ofIndia decided upon bulk tendering by NTPCand DVC as the methodology for awardingunits of Supercritical power plants. Theseplants are typically large with minimum unitcapacity of 660 mw. One of the primaryobjectives of introducing Ultra Mega Power

Plants was to pave the way for progressiveindigenization of supercritical technology.
Several companies expressed interest inaugmenting or setting up manufacturingfacilities in the country for supercritical units.
The list included Bhel for Boiler and TurbineGenerator (BTG), Ansaldo Caldie GB(Boiler), L&TMHI (Boiler and TG),ToshibaJSW (TG) and Alstom-BharatForge (TG). Larsen & Toubro already had atie-up with Mitsubishi Heavy Industries of
Japan for manufacturing supercritical steamturbines and generators in India.
This paper attempts to evaluate the impactof supercritical technology in power sectoralong with the role it is likely to assume in
the future. It contains a summary of thestatus of manufacturing facilities in India forsupercritical equipments (boilers, turbinesand generators) and Indias preparednessfor implementing the same in generation ofpower.

ECHNOLOGY
Background
The 1992 climate treaty made it clear that,while the developed nations must take theresponsibility for the current buildup ofgreenhouse gases in the atmosphere andnecessarily take the lead in combatingclimate change; developing nations alsohave a role to play in protecting the globalclimate.
In 1997, Kyoto Protocol enforced theindustrialized nations to specify and commitfor legally binding reductions in emissions of
greenhouse gases. Although developingcountries, including India and China, did notcommit to reductions immediately because
of lower per-capita emissions and inability toabsorb the initial costs of changing tocleaner fuels, the pressure on them to do sois building up.
India and China are projected to becomemajor carbon emitting nations because oftheir energy requirements and coalgeneration sources. The graph belowdepicts the trends of carbon intensity ofthese two nations in the past (1980-2003).
China has made great strides in reducingCO2 emissions from coal fired generationunder its large substitutes for small (LSS)program. It is now Indias prerogative to
demonstrate its efforts for the betterment ofthe environment a cause India believes in.

Supercritical technology inPower Generation
In order to develop additional powergeneration capacity, the existing domestic
manufacturing capacity needs to be up-graded and enhanced. For the reasons
stated above there is a preference for super-critical technology in the country.
About 60% of coal based capacity in XIIPlan and 100% capacity in XIII Plan isplanned to be based on supercriticaltechnology. Table below gives the projectedcapacity addition based on supercriticaltechnology up to 13th Plan:

Supercritical Technology is widelyestablished and accepted with more than500 units in operation across the world. InIndia, NTPC is implementing the technologyat Sipat and Barh thermal power stationswith super critical parameters of up to
5660C. In Japan and Germany, they could
achieve a temperature range of 566 to593
0C. The highest ever efficiency achieved
with super critical technology is at atemperature 600
0C.

Methodology for Induction ofSupercritical Technology inIndia
After several discussions on the issue ofinduction of supercritical technology forcapacity addition in the power sector, amethodology for the same was decided in
July 2008 by central government. This wasfollowed by several recommendations andrevisions and at last the approach to beadopted for super critical technologyinduction was finalized in February, 2009.
According to the approach:
NTPC and DVC would go in for bulktendering of 11 units of 660 MW in 5projects via International CompetitiveBidding (ICB).
The companies would be allowed to bid
separately for boilers and turbines. The tender for Boiler Package will be
split between two bidders. The lowestbidder (R1) in the boiler package will getthree projects and the second-lowestbidder (R2) will get two projects aftermatching price quoted by R1. Thenumber of units for each bidder wouldbe decided as per the groupings that will
be taken up by NTPC (to be decided ata later stage).
The Turbine and generator packagewillcomprise of five projects, the tender forwhich will be in groupings of 2+ 2 + 1(i.e. three bidders). This package ismore in number in terms of groupingsbecause there are more players (four orfive) in this category. In respect ofturbine generator package, if BHEL isR1, the 2nd grouping will go to R2 and3rd grouping (of one project) to R3subject to price matching.
In either case, if BHEL is not the lowestbidder, it will be given the groupearmarked for the second lowest biddersubject to price matching.
The winners of the tender would berequired to set up manufacturingfacilities in India with a PhasedManufacturing Program (PMP). In caseof existing manufacturing facilities ofsuch bidders in India the facilities wouldbe appropriately augmented.
The PMP envisages setting up ofmanufacturing facilities for boiler andturbine generators in 48 and 52 monthsrespectively. It was agreed that bidderswill be asked to give firm commitment toset up manufacturing facilities within thisperiod as a part of qualificationrequirement.

It was proposed that the first unit of theproject awarded to a bidder becompleted within 48 months with a gapof 6 months between units for the sameproject. The gap would be of 2 monthsbetween the first units of different
projects awarded to the same bidder.
Induction of super-critical units through bulktendering was accorded the highest priorityby the Ministry of Power (MOP). As per theMOP guidelines issued vide letter datedSeptember 4, 2009, Notice Inviting Tender(NIT) is to be issued within 45 days of issueof this letter i.e. before October 18, 2009.
NTPC floated tenders inviting bids for 11units of 660 mw on October 16, 2009. Theunits for which the bids were invited include
nine units of NTPC and two units ofDamodar Valley Corporation. The 11 unitsare to be used in five power projects in thestates of Bihar, Uttar Pradesh, Maharashtraand Jharkhand. The company invitedseparate international competitive bids forboiler and steam turbine generator (STG)sets. So far, five companiesBhel, L&T-Mitsubishi Heavy Industries (MHI) combine,
Alstom-Bharat Forge, Toshiba-JSW andItalian company Ansaldo Caldie haveexpressed their interest in participating inthe bulk tendering for supercriticalequipment.
At the time of deciding upon themethodology, there were three prospectivebidders for the Boiler package: BHEL-
Alstom, L&T-Mitsubishi and Ansaldo, and
fourfor the Steam Turbine Generator (STG)package: BHEL-Siemens, L&T-Mitsubishi,Bharat Forge-Alstom and Toshiba-JSW.However, other players may also come uponce the tenders are issued.
The Implementation ofSupercritical Technology
Supercritical Projects Planned
The Ultra Mega Power Projects along withsome other power plants have beenenvisaged to be set up with supercriticalparameters. NTPC and the state utilitieshave proposed to set up a number of powerstations based on supercritical technology.
The list of projects include NTPCs Darlipalliin Orissa (4x800 mw), Tanda expansion inUttar Pradesh (2x660 mw), Pench inMadhya Pradesh (2x660 mw), NTPC-UttarPradesh joint ventures Mejja in UP (2x660mw), NTPC-Bihar JVs New Nabinagar inBihar (2x660 mw), Mahagencos Koradi inMaharashtra (3x660 mw), MahagencosDhopawe in Maharashtra (2x800 mw),BHEL-UP JVs Obra in UP (2x800 mw) andBhel-Tamil Nadu Electricity Board JVsUdangudi in Tamil Nadu (2x800 mw).

Supercritical Projects under
Execution
Currently, supercritical technologies areunder installation at Sipat and Barh thermalpower stations of NTPC. Tata PowersMundra project (UMPP) also importedturbines from Toshiba and boilers fromDoosan, Korea with super criticalparameters.
Manufacturing Facilities for
Supercritical technology in
India
Considering the large capacity additionrequired for supercritical based projects inthe country, it is necessary to set upadequate manufacturing capacity within thecountry so that the necessary facility andtechnology is available to provide long termsupport for services and spares.
Domestic Manufacturers
BHELhas already entered into collaboration
with Alstom and Siemens for manufacturingof super-critical boilers and turbo-generatorsrespectively. It is in the process ofaugmenting its manufacturing capacity forcoal based thermal units to about 10,000MW per annum by December, 2009 whichcan cater to sub-critical and/or supercriticalunits.
International manufacturers
Efforts are being made to attract
international manufacturers for taking up theequipment manufacturing in India. Someinternational manufacturers have alreadyformed or are in the process of forming jointventure companies with Indian partners toset up manufacturing facilities forsupercritical boilers and turbine generatorsin the country.
The proposal for bulk tendering of fiveprojects constituting eleven units withmandatory condition of setting upmanufacturing facilities within the country
sparks off a new era in super criticalequipment manufacturing in India. It helps inattracting new players into the sector.

CONCLUSION
The construction of the 1980 MW Sipat coalfired power plant by NTPC marks the newgeneration of supercritical power plants forIndia. The induction of this technology bringswith it a lot of hope and questions. Thoughthe application of the technology in powergeneration is not a panacea for theproblems of delays in capacity addition andinefficient units plaguing the generationsector, it has the potential to act as animportant stepping stone to evolving one.
The large size of units will enable fastercapacity addition due to economies of scale.The fact that it is a proven technology forreducing environmental impact may helpspeeding up capacity additions further bymeans of support from environmentallobbyists and faster environmentalclearances. Supercritical technology will alsosignificantly address the issue ofinefficiencies in generation.
Supercritical technology may be the right
solution but it is unfortunately not a readymade one. Till recently, most benefits of thistechnology were known to accrue for goodquality, low ash content coal. So there maybe some upgradations required to adopt itfor Indian high ash coal.
The benefits are defined. It is the duration oftransition from sub critical to super criticalthat will determine the timing of thesebenefits. The transitional phase will dependon the speed with which new manufacturingcapacities for this technology are set up, the
existing ones upgraded, and the time takenby manpower of existing generatingcompanies to adapt to a new technology.
Whether on time or post delays, thetechnology and manufacturing willmaterialize, what is important and worthcelebrating is Indias commitment to use itsresources preciously and act responsibly inreducing its carbon footprint.
