India’s Energy Scenario

force in India for the approach Decades Anil Kakodkar Chairman, atomic Energy Commission, India emailprotected gov. in The reforms initiated in India since the beginning of the mid-nineties have led to rapid economic progress and better event rates. In the first decade of this century the suppuration rates see to be still better. Studies by several academics and consultants forecast continued last offshoot rate for the next several decades.Ill quote two much(prenominal) studies, iodin by Dominic Wilson and Roopa Purushothaman of Goldmann Sachs 1 and the other by Dani Rodrik and Arvind Subramanian of the International M hotshottary monetary fund 2. Wilson and Purushothaman write, India has the potentiality to show the steadyest gain over the next 30 to 50 years. Growth rate could be higher than 5 pct over the next 30 years and close to 5 sh atomic number 18 as late as 2050 if maturation proceeds successfully. Rodrik and Subramanian write, .. rowth in expectant stoc k together with appendage in factor productivity subject yield divulgeput fruit of 5. 4 per centum. Over the next 20 years, the working age population is project to grow at 1. 9 percent per year.If educational attainment and discriminateicipation rates remain unchanged, roil growth leave behind contribute another 1. 3 percent, yielding an come growth rate of 6. 7 percent per year, or a per capita growth rate of 5. 3 percent. This is a lower bound estimate and, flush so, would be signifi washbasintly greater than the per capita growth rate of 3. percent achieved in the 1980s and 1990s. Over a 40-year period, a 5. 3 percent growth rate would increase the income of the average person nearly 8-fold. Growth in economy is make practical by several inputs, the two closely all important(p) cosmos goose egg and human resource. In this conference, we are have-to doe with close postcode and so Ill confine myself to thrust. Energy is the engine for growth. It multiplies hu man labour and increases productivity in agriculture, industry as comfortably as in services. To sustain the growth rate in economy, competency supply has to grow in tandem.For a large country akin India with its over one billion population and rapid economic growth rate, no single zip resource or technology constitutes a panacea to address all issues related to availability of give notice supplies, environmental impact, particularly, climate change, and health externalities. Therefore, it is necessary that all non-carbon emitting resources become an integral part of an energy mix as diversified as possible to under(a)take energy security to a country like India during the reach century.Available sources are low carbon fossil fuels, renewables and atomic energy and all these should be subject of change magnitude level of research, development, demonstration and deployment. In the section of Atomic Energy, we have conducted a study with the aim to quantify the likely gr owth in energy demand in India, and the role nuclear energy has to play in the decades to come. The ultimate objective was to formulate a strategic plan to meet the projected role to be played by nuclear energy 3.Energy intensity of gross domestic product, defined as the ratio of the energy consumption to the GDP, has been observed to follow a certain trend worldwide. down the stairs a certain level of development, growth results in increase in energy intensity. With further growth in economy, the energy intensity starts declining. base on selective information by International Energy dresser 4, overall energy intensity of GDP in India is the same as in OECD countries, when GDP is calculated in cost of the purchasing power paratrooper (PPP). Energy-GDP pushover, the ratio of the growth rates of the two, remained around 1. from early fifties to mid-seventies. Since and then it has been continuously decreasing. Electricity is the most important component of the primary energy. Electricity-GDP pushover was 3. 0 till the mid-sixties. It has also decreased since then. Reasons for these energyeconomy elasticity changes are demographic shifts from rural to urban areas, structural economic changes towards luminosity industry, impressive growth of services, increased use of energy efficient devices, increased efficiency of conversion equipments and inter-fuel substitution with more efficient alternatives.Based on the CMIE data 5, the average value of the Electricity-GDP elasticity during 1991-2000 has been calculated to be 1. 213 and that of the primary energy- GDP elasticity to be 0. 907. Estimating the future GDP growth rates of India from the projections made by Dominic Wilson and Roopa Prushothaman 1, taking the primary energy intensity fall to be 1. 2 percent per year 6, extrapolating the electricity intensity fall from yesteryear data till 2022 and subsequently a constant fall of 1. 2 percent year, the growth rates of the primary energy and galvanis ing energy have been estimated as follows. Period elementary Energy Electricity percent one-year Growth Percent Annual Growth 2002-2022 4. 6 6. 3 2022-2032 4. 5 4. 2032-2042 4. 5 4. 5 2042-2052 3. 9 3. 9 These rates are the basis of the projections reported 3. It may be recalled that historical primary energy and electricity growth rates during 1981- 2000 were 6 percent per year and 7. 8 percent per year respectively.Based on the growth rates given in the above table, per capita electricity generation would reach about 5300 kWh per year in the year 2052 and total about 8000 TWh. This would correspond to an installed capacity of around 1300 GWe. Annual primary energy consumption would increase from about 13. 5 EJ in 2002-03 to about 117 EJ in 2052-53. By then the cumulative energy white plague will be about 2400 EJ. The present status of various fuel-resources in India is given in the table 1. The domestic mineable coal (about 38 BT) and the estimated hydrocarbon militia (about 12 BT) together may provide about 1200 EJ of energy.To meet the projected demand of about 2400 EJ, one has to tap all options including using the k forthwith fossil reserves efficiently, looking for increasing fossil resource base, matched import of energy (including building gas pipe lines whenever and wherever permitted establish on geo-political considerations and found feasible from techno-commercial considerations), harnessing full hydro potential for generation of electricity and increasing use of non-fossil resources including nuclear and non-conventional.Before proceeding further, I would like to explicate the status of nuclear power technology in India. Comprehensive expertness in all aspects of nuclear fuel cycle and Pressurized Heavy pissing nuclear reactors (PHWRs) has been acquired through self reliant means in India. PHWRs which constitute the ground tackle of the first stage of our nuclear power class are the most efficient systems in terms of uranium util ization and would enable about 10 GWe of nuclear installed capacity with our modest indigenous uranium resources.Having tied up the PHWR programme upto around half centering mark, we have now embarked on the development of Fast Breeder Reactor (FBR) base second gear stage of our programme with the construction of the 500 MWe Fast Breeder Reactor launched in October last year. Our studies indicate that we should be in a role to support around 500 GWe power generation capacity based on plutonium bred from indigenously available uranium. This is a part of the schema of three stage programme formulated by India right in the beginning of the programme aimed eventually at exploitation of our vast atomic number 90 resources.With decades of RD in our laboratories and Industry, India has come a longsighted way since the inception of the programme and the on-going efforts are aimed at further amend the economy, enhancing safety and expanding the programme to meet the increasing ele ctricity demand in the country. The 540 MWe PHWR unit at Tarapur that went critical on 6th March, about 8 month ahead of schedule is an important landmark in terms of efforts in this direction. In addition to the indigenous technology, the Indian power programme includes two GE-BWRs which were set up as turnkey projects right at the inception of our programme.While these reactors are running well as a result of comprehensive backfits and upgrades carried out indigenously, our experience in terms of securing reliable fuel supply has not been satisfactory. Two 1000 MWe VVERs are presently under construction at Kudankulan and would contribute additional carbon free electricity to Indian grids when completed. Coming back to the energy growth scenario 3, the study points out that it is necessary to develop metallic fuel for the degenerate reactors during the next one decade.Metallic fuels have short doubling time and can ensure a fast enough growth in nuclear installed capacity. Assumin g that the fast reactors to be set up after 2020 are based on metallic fuel, the study calculates the maximum possible contribution that can be made by nuclear till the middle of the century. Hydro and non-conventional potential being limited, the remaining demand has to be met by the fossil fuels. The results indicate that it is possible to have one quarter of the contribution coming from nuclear by the middle of the century, if the fast reactor growth follows the course outlined.Even after the growth projected by the study, there will be shortages and the country will continue to import energy as at present. Research and development plans have to be formulated to ensure that new technologies can be deployed to reduce energy imports. Three efforts being made by the Department of Atomic Energy are worthy of mention here in this context. Bhabha Atomic Research magnetic core is working on development of a Compact High Temperature Reactor with the aim of producing hydrogen, which coul d be the most important energy carrier in the future.Several institutions within the Department of Atomic Energy in India are together working for the development of Accelerator compulsive Systems, so that one could sustain growth with thorium systems and move towards incineration of long lived radioactive wastes. The Institute for Plasma Research (IPR), is spearheading the Indian effort in developing a fusion based system for the production of energy. bingle of the worlds first super conducting steady state tokamak with elongated diverter plasma having 1000 second operation capability is nearing completion at IPR.The Indian population corresponds to one sixth of world population. However, the carbon dioxide sack from India is only around 4% of the global liberations. On the basis of current energy mix and the present day technologies for electricity production, the CO2 emission from India alone could become as much as half of the present level of global emission in a few decad es from now. A larger share of nuclear power in India beyond what would be realized through indigenous efforts would, in principle, contribute to further evasion of CO2 emission which otherwise would be inevitable.To conclude, the first stage of the indigenous nuclear power programme involving setting up of pressurized heavy urine reactors is now in industrial domain. With the start of construction of the 500 MWe fast reactor in October last year, the second stage has been launched. It is time for India to race the implementation of the second stage and development of the third stage of the nuclear power programme. In parallel, India has to continue to work towards development of emerging nuclear energy technologies to address its long term energy requirements which are therefore very large.References 1 Dominic Wilson and Roopa Purushothaman, Dreaming with BRICs the path to 2050 Global Economics Paper No 99, Goldmann Sachs, 1st October 2003. 2 Dani Rodrik and Arvind Subranium, Wh y India can grow at 7 percent or more projections and reflections, IMF Working Paper, WP/04/118, July 2004. 3 R.
