  9. Installed Power Generating Capacity in Karnataka (Approximate figures in some years) (Reference: “Belakaayitu Karnataka’ by Dr. Gajaanana Sharma)

  10. Power supply in Karnataka (Source: Central Electricity Authority)

  11. Available power capacity in Karnataka as on 30.6.2011 (MW)

  12. Available Power capacity (MW) in Karnataka ason 30.6.2011 (Source: CEA Website)

  13. Karnataka’s Power Scenario Gross power availability in 2011 = about 12,147 MW; net power availability >> about 9,500 MW; but maximum power demand met = 7,815 MW Why this gap ??? Overall industry efficiency between 40 -50% Gross inefficiency leading to plan about 50% more capacity than really needed Inefficiency in managing the existing capacity is the prime reason for the power cuts each year

  14. Power saga in India • Between 1989 & 2009 • Installed generating capacity increased from 58,012 MW to 1,52,148 MW ( + 162%) • Between 2000 & 2008 • Monthly generation from conventional sources increased from 43,596 MU to 65,057 MU (+50%) • Between 1992 & 2006 • National per capita electricity consumption increased from 283 kWH to 429 kWH ( +52%) • National Per capita electricity consumption at present > 700 Units • per capita consumption in Karnataka = 720 Units (in 2009) • per capita consumption in Bangalore = 2,674 Units (in 2009) • per capita consumption in villages << 200 Units • But 44% of the households have no access to electricity even in 2009. • Many villages remain unelectrified; huge power cuts throughout the year; poor quality of supply; gross inefficiency; vulgar levels of inequity continues. • Multiple crises continue !!!

  15. Many serious Questions to the society • Electricity Supply is needed no doubt. But ……. • How much? – highper capita consumption ? • How?? – by any means?? • At what cost??? – at any societal cost ???

  16. Salient features of Indian Power Sector • Power sources /Power plants concentrated in few areas; requires massive transportation and transmission infrastructure • Gross inefficiency in all segments of the sector • Massive reliance on conventional and centralised power generation • No diligent studies of realistic future electricity requirement; Unrealistically higher projection of future demand • Complete absence of holistic approach / long term perspective • Discernible absence of attention to welfare needs of bio-diversity/ masses • Mostly new merchant power plants for profit motive; true costs and benefits to society of power plants never determined • R&R and environmental compliance has been abysmally poor; Insensitivity to civil society’s views

  17. Major Issues with Fossil Fuel Power Plants • (coal, gas, diesel) • Economic • Unsustainable pressure on natural resources such as land, water and minerals; reduced agricultural production; • Social • Peoples’ displacement due to large sizes of power plants; health; decay of rural India • Environmental • Global Warming; pollution of land, water and air; acid rains; impact on bio-diversity

  18. Major Issues with Dam based Hydro Power Plants • Economic • Demands large tracts of forests and fertile land; water logging; affects the economy of the down stream population; deposition of silt in dams; deprivation of the same down streams • Social • Peoples’ displacement and health; community leadership issues • Environmental • Methane emission, submersion and fragmentation of forests; loss of bio- diversity; downstream areas get deprived of fertile silt

  19. Major Issues with Nuclear Power Plants • Economic • Demands large tracts of forests and fertile land; huge Capital costs; long term waste management costs; serious shortages of nuclear fuels; impact on plant and animal food • Social • Peoples’ displacement and health; community leadership issues; intergenerational issues • Environmental • Mining related pollution; radiation emission during operations and from nuclear wastes for centuries

  20. PART II Dangerous Reliance on Coal Power Plants

  21. Major Issues with Coal Power Plants • Huge pollution impacts: air, water and land • About 1 acre per MW of land • Requirement of about 3.92 million cubic metres of water per 100 MW per year • Additional requirement projected = 4608 million cubic meters. • This water can irrigate about 920,000 ha of land in a year, • provide drinking water to about 84 million people or 7% of India’s population • every day for a year • Demands lot of our resources; displacement of poor; fast running out reserve; • no replacement is being considered • System unable to meet the growing coal demand • requires about 2000 million tons (2 billion tons) of coal every year • More coal mines lead to destruction of forests • against forest & tree cover target of 33% it is << 20% • Low efficiency and ever increasing costs • solar power cost projected to become comparable by 2017

  22. Major Issues with Coal Power Plants (contd…) • Serious concerns on health aspects; threat to bio-diversity • Report of Physicians for Social Responsibility; Asthma, lung cacer, heart disease and stroke • Sierra Club’s fight – stopping 0ver 150 plants ; Report “Human, Social, and Environmental Damages Avoided through the Retirement of the US Coal Fleet” • GreenPeace – “the true cost of coal” >> people and the planet are paying for the world’s dirtiest fuel • Coal burning – a major contributor to Global warming • US - $345 billion a year in hidden expenses (Harvard University research) • not borne by miners or utilities, including health problems in mining communities and pollution around power plants • Critically Polluted Areas in India have coal power plants • Sulphur dioxide, high ash content, Mercury, traces of radio-activity • Toxic trace elements such as arsenic (As), lead (Pb), cadmium (Cd) • Poor regulatory measures • Huge additions to coal power capacity planned (Prayas Pune Report) • 700,000 MW additions (84% of all planned) against existing 115,000 MW; • Few clusters with very huge coal power capacity • heavy reliance on imported coal; mostly in private sector

  23. Thermal Power Plants Coming Up in Critically Polluted Areas (Source: Prayas Pune Report “THERMAL POWER PLANTS ON THE ANVIL Implications and Need for Rationalisation ) Critically Polluted Area Proposed Capacity Addition in MW in the District Angul, Orissa >> 17,840 MW Bharuch, Gujarat >> 15,760 Singrauli, M.P. >> 15,240 Cuddalore, Tamil Nadu >> 10,140 Jharsuguda, Orissa >> 9,075 Chandrapur, Maharashtra >> 7,800 Korba, Chhatisgadh >> 7,570 Visakhapatnam, A.P. >> 4,690

  24. Dangerous reliance on coal power – huge implications • Integrated energy policy has also projected a total generating capacity of about 800,000 MW by 2031-32, out of which 400,000 MW may have to be coal based. • Minister of State for Coal: "There are no two opinions about the need to switch over to other modes of power generation ……. Coal-based power production has to be restricted". • Future need for huge quantity of coal import; • 630 million tons annual domestic capacity • More than 1000 million tons to be imported. • Energy security, due to import dependence, will be serious issue • At present Approximately 80 coal-based thermal power stations operating • >> 90% power coal supply responsibility is catered to by Coal India Limited (CIL)

  25. Dangerous reliance on coal power – huge implications • Large clusters of coal power plants planned • Vidarbha >> 30,000 MW • Konkan >> 40,000 MW • AP coast >> 40,000 MW • Orissa >> 50,000 MW • Singruali/Rihand region; Chattisgarh • CPPs even in states like Karnataka, Kerala and HP without coal reserve • Coastal areas are targeted for ease of import and sea water • impact on fresh water bodies and fishing • More coal fields are being opened • More of forests are getting destroyed • More of tribals being displaced • Global warming and Climate Change : What is India’s commitment ?

  26. Coal power Efficiency

  27. Global Warming and Electricity Industry

  28. The Impact of Electricity Industry on Global Warming • About 38% of GHG emission at the national level (53% of CO2 emissions in India); [MoEF report of 2010] • Large dams - tropical deforestation produces 20 per cent of all carbon emissions caused by humans, and destroys long-term carbon sinks • Methane from dams is highly potent GHG • Additionally – power stations consume a lot of natural resources; land, water, fossil fuel etc; displace people; atmospheric and ground water pollution; • Transmission lines need large tracts of lands / forests • Nuclear fuel cycle itself consumes horrendous amount of energy

  29. Global Electricity Usage and CO2 Emission (Year 2007)(Source: Key World Energy Statistics, IEA, 2009)

  30. Implications on Global warming ? “Emissions have been, and continue to be driven, by economic growth; yet stabilization of greenhouse-gas concentrations in the atmosphere is feasible and consistent with continued growth.” “Emissions from deforestation are very significant – they are estimated to represent more than 18% of global emissions” “Curbing deforestation is a highly cost-effective way of reducing greenhouse gas emissions.” What our society is doing at present is to supply inefficiently derived energy from limited conventional sources at subsidized rates for highly inefficient and / wasteful end uses, for which the real subsidy cost will be passed on to future generations.

  31. Concerns about dam based hydro power and nuclear power are equally grave but of different nature

  32. Extent of Inefficiency • “India’s power sector is a leaking bucket; the holes deliberately crafted and the leaks carefully collected as economic rents by various stake holders that control the system. The logical thing to do would be to fix the bucket rather than to persistently emphasise shortages of power and forever make exaggerated estimates of future demand for power. Most initiatives in the power sector (IPPs and mega power projects) are nothing but ways of pouring more water into the bucket so that consistency and quantity of leaks are assured ….” • Deepak S Parekh, Chairman, Infrastructure Development Finance Corporation, September 2004. • As per 13th Finance Commission, national level financial loss of ESCOMs could be • > Rs. 69,000 Crores in 2010-11 and • > Rs. 116,000 Crores in 2014-15

  33. With this background • Do we need many more large power projects? • Must they be fossil fuel OR large dam based OR nuclear based? • Since fossil fuel & dam based power projects contribute heavily to the global warming effect what suitable alternatives are available to us ? • Since the policies since independence have largely failed to meet our requirements, is there a need for a paradigm shift?

  34. PART III Towards an Integrated Energy Policy

  35. IEP’s projection • total power capacity should increase from about 160,000 MW in 2006 to about 800,000 MW in 2031. • coal power from 80,000 MW to 400,000 MW • hydro from 36,000 MW to 150,000 MW • nuclear from 4,800 MW to 20,000 MW • This scenario throws up huge problems to our society • Unsustainable demand on land, fresh water and natural resources • Unacceptable levels of pollution • Population displacements • High GHG emissions • Reduced energy security due to dependence on imports

  36. Integrated Energy Policy Desirable Vision: Develop a policy to enable meeting the legitimate demand for energy of all sections of the society at realistic prices on a sustainable basis without compromising the interest of other aspects of the society such as flora, fauna and general environment.

  37. Towards an Integrated Energy Policy Heavy focus on efficiency improvement, DSM and conservation • Low PLF in the existing thermal power stations; as low as 25% in some states; a major concern • Increase overall PLF from 75% to 90%; can increase availability by more than 10,000 MW • Increase load factors of hydel plants • Can provide additionally 3,000 to 5,000 MW • AT&C loss reduction from 30% to 10% • Savings of about 15,000 to 20,000 MW • Usage efficiency increase • Savings of 20,000 to 25,000 MW Existing electricity infrastructure can provide > 45,000 MW more

  38. Towards an Integrated Energy Policy • Considerable scope in energy usage efficiency and conservation • DSM potential: 15% as per IEP • Huge scope in distributed type of renewable energy sources

  39. N&RE Potential In India (Source: MNRE)

  40. Energy Security for Future Can be feasible only through: • Integrated Energy Resource Management • Holistic Approach • Sustainable Practices • Concern for other Sectors of the Society

  41. The road ahead • Planning Commission estimates that CO2 generated from energy use can be reduced by 35% through effective deployment of efficiency, DSM measures and renewable energy sources. • Planning Commission’s main action recommendation for energy security is: “relentlessly pursue energy efficiency and energy conservation as the most important virtual source of domestic energy”. • Bureau of Energy Efficiency has estimated: at the prevailing cost of additional energy generation, it costs a unit of energy about one fourth the cost to save than to produce it with new capacity.

  42. How to meet the demand in future years ? • Efficiency & DSM measures will meet part of the additional demand • Renewable energy sources is the answer !!!

  43. New & renewable energy sources • Solar PV cells • Solar water heaters, Solar cookers & Solar driers • Solar street lights • Solar water pumps • Small size wind mills • Bio-mass plants (eg. Gobar gas plants) • Mini & micro hydel plants • Hybrid of solar, wind and bio-mass

  44. Major advantages of Renewable energy sources • -distributed source mode as against large ones • people friendly & environmentally friendly • self sufficiency for rural communities and individual houses • reliable supply option; no recurring charges • rural employment opportunities • leads to reduced urban migration; a sustainable option • most suitable to rural communities • accelerated rural electrification • reduced burden on grid supply • reduce GHG emissions • will reduce the need for coal, dam and nuclear power plants

  45. New & renewable energy sources • European Union has a plan to meet 20% of all its energy needs by 2020 AD through N&RES • Israel is reported to be targeting 50% • Greenpeace has come up with plans to meet 100% & 50% of energy needs of New Zealand and India • Country has a huge potential in harnessing roof top solar PVS; 10% of households @ 2 kW >>> 200,000 MW • Additionally roof top surface of schools, colleges, industries, commercial, warehouse and office buildings – huge potential • Bio-mass energy at community levels • Combination of solar, bio-mass and wind energy • Germany and Japan >> replacing nukes with RES

  46. A case study • An identified need to meet 400 MW of additional demand • -------------------------------------------------------------- • Option I : 400 MW Gundia hydel power plant in WGs • COSTS: Direct Financial Cost : About 2,000 Crores • Societal Costs + tax incentives • loss of about 110 hectares of thick evergreen rainfall forest • loss of fertile agricultural lands • displacement of people • perpetual loss of agricultural production and forest produce • Huge impact on local bio-diversity • A total of unknown but huge ecological cost • BENEFITS : About 400 MW of power at less than 25% load factor • Long term employment for about 50 people(?) • Dividend to state govt. ??? • Additional revenue to KPCL

  47. Option II : Integrated Energy Management Approach • One or more of the following options can provide much more power • COSTS • T&D loss reduction - 600 MW >> 900 Crores • Utilisation loss reduction / DSM - 600 MW >> 900 Crores • Usage of CFLs - 400 MW • OR A combination of • Wind energy • Biomass • Solar – Water heating • Solar –residential lighting • BENEFITS • Negligible societal cost; negligible or nil land and displacement • No loss of forests & bio-diversity • Negligible or nil health or environmental costs • Perpetual benefits • Highly reduced T& D losses; reduced man power costs • Boost to agricultural and rural employment
