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

Page 14: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.
Page 15: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

Many serious Questions to the society

Electricity Supply is needed no doubt. But …….

• How much? – high per capita consumption ?

• How?? – by any means??

• At what cost??? – at any societal cost ???

Page 16: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 17: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 18: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 19: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 20: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

PART II

Dangerous Reliance on Coal Power Plants

Page 21: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 22: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 24: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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)

Page 25: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

• 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 ?

Coal power Efficiency

Page 28: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 30: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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.

Page 31: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

nature

Page 32: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 33: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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?

Page 34: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

PART III Towards an Integrated Energy Policy

Page 35: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 36: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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.

Page 37: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 38: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 39: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

N&RE Potential In India(Source: MNRE)

Potential: (Grid interactive power only)

Remarks

1. Wind energy > 45,000 MW

2. Small hydro 15,000 MW

3. Solar over 5,000 trillion

kWH/year

Potential estimated to be more than the total energy needs of the country

4. Bio-mass >> 25,000 Not known

Page 40: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

Energy Security for Future

Can be feasible only through:

– Integrated Energy Resource Management

– Holistic Approach

– Sustainable Practices

– Concern for other Sectors of the Society

Page 41: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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.

Page 42: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

How to meet the demand in future years ?

Efficiency & DSM measures will meet part of the additional demand

Renewable energy sources is the answer !!!

Page 43: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 44: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Page 45: Concerns with Indian Power Sector Socio-environmental problems due to over reliance on Coal Power Plants Washington September, 2011 Shankar Sharma Power.

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

Break up of Projected Installed Capacity by 2031-32(As an alternative to IEP)

Capacity (MW)

Share in total capacity by

2031-32

Comments

Coal 110,000 28 % Increase from present capacity of 80,000 MW; IEP has projected 470,000 MW; gradual reduction; early peaking

Hydro 40,000 10 % Only < 25 MW capacity R-0-R plants only after 2032;Against IEP projection of 150,000 MW

Nuclear 10,000 3 % Only known sources of domestic nuclear fuel to be used; targeted to be replaced fully by 2050

Natural Gas 25,000 6 % Targeted to be replaced fully by 2050

Solar (Grid interactive large size units only)

60,000 15 % National solar mission target of 20,000 MW by 2020 should be ramped up adequately

Solar (Roof-top isolated and Grid interactive small size units )

60,000 15 % Huge potential to be harnessed early by policy interventions; a must for accelerated rural electrification and for T&D loss reduction

Wind 30,000 8 % Same as projected by IEP; expected to increase share after 2032 through off-shore wind farms

Bio-mass 50,000 13 % Same as projected by IEP; mostly community based plants

Other renewables (Ocean energy and Geo-thermal)

7,000 2 % Nascent technologies but huge potential; likely to get better focus after 2032

Total Capacity 390,000

WAY FORWARD

There are credible ways of meeting our electricity needs without a large number of conventional power plants !

The society must move resolutely in this direction !! Half measures will not suffice !!!

A holistic, responsible and highly accountable approach

People centric policies are essential and feasible. Effective public consultations

Sustainability should be the criteria Obligations to future generations
