Why efficiency in Power Sector Is Important ?

Energy emergency at the global level

35% of all GHGs associated with energy sector

1.3 Billion people without electricity; many others have barely enough

In US Thermoelectric energy (including coal, nuclear and natural gas) are fastest growing use of freshwater resources i

53% of fresh water usage in 2005

Large energy projects have displaced millions of people, destroyed ecosystems, natural resources fueled climate change

Fossil fuels fast running out; but growing demand for energy

Future of energy supply and demand Energy conservation, efficiency improvements and decentralized

renewable energy best ways to reduce energy poverty sustainable and climate resilient way

Energy emergency at the global level – as per OECD Projections By 2050 world economy will be four times larger

will need 80% more energy without new policy action

Global greenhouse gas (GHG) emissions projected to increase by 50%, primarily due to a 70% growth in energy-related CO2 emissions.

Terrestrial biodiversity is projected to decrease by a further 10% by 2050, with significant losses in Asia, Europe and Southern Africa.

Globally, mature forest areas are projected to shrink by 13%.

Air pollution is set to become the world’s top environmental cause of premature mortality

Projection: by 2050, 60-70% of energy usage likely to be as electricity

Electricity is cause of 38% of GHG emission in India (53% of CO2 emissions in India); [MoEF report of 2010]

Power saga in India

Installed generating capacity increased by about 220 times between 1947 and 2013

Between 1989 & 2013Installed generating capacity increased from 58,012 MW to 2,25,800 MW ( + 389%)

Between 1992 & 2013 National per capita electricity production increased from 283 kWH to 800 kWH ( +283%)

But about 30% of the households have no access to electricity even in 2011.Many villages remain unelectrified; huge power cuts throughout the year;

poor quality of supply; gross inefficiency; vulgar levels of inequity continues.

Multiple crises continue !!!

In this background many serious Questions to the society

Electricity Supply is needed no doubt. But …….

• How much ? – leading to high per capita consumption ?

• How ?? – any how & by any means?

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

Can additional power projects be in the benefit of whole society ?

In Indian context the main challenges for power sector:

critical need for electricity / energy for development of weaker sections of society

how to eliminate the power cuts ? how to ensure quality power to all ? how to meet the additional demand ? how not to compromise overall welfare needs of masses?

must our forests, rivers and bio-diversity become expendable in order to meet the uncontrolled demand for electricity? Is capita consumption a good indicator of development?

Equitable distribution of available electricity should be yardstick !

One answer which seem to be obvious:

Keep increasing the installed generating capacityAnd

Increase T&D network correspondingly

------------------------------------------------

But the reality is:

How much increase is techno-economically feasible?Is there a natural limit?

Can we ensure true welfare of our masses?

Fossil Fuels (coal, gas, diesel)

Dam Based Hydro Nuclear Power

Economic Issues

Huge pressure on natural resources such as land, water and minerals; reduced agricultural production; fast depleting; increasing costs

Demands large tracts of forests and fertile land; water logging; increasing costs

Demands large tracts of forests and fertile land; Huge Capital costs; long term waste management costs; increasing costs

Social IssuesPeoples’ displacement and health; inter- generational inequity

Peoples’ displacement and health issues; inter- generational inequity

Peoples’ displacement and health; inter- generational inequity

EnvironmentalIssues

Global Warming; pollution of land and water and air; Acid rain

Methane emission, submersion and fragmentation of forests

Mining related pollution; radiation emission for centuries; the nuclear energy cycle itself consumes lot of energy;

Major issues with conventional technology power sources

Present scenario - Problems are getting worse

Chronic power cuts in almost all states; peak demand and annual energy

Dissatisfaction for all categories of consumers including the farmers

Gross inefficiency in the sector; massive inequity in electricity supply

Continued reliance on conventional power sources; planning for huge additions in generation and transmission; ever increasing complexity of

grid

Indifference to the natural limits to conventional energy sources; fast depleting natural resources

Absence of long term view; lack of sustainability; lack of obligation to the future generations ; empty rhetoric on Global Warming

Very poor financial conditions; cumulative loss > 150,000 Crores

Continued absence of professionalism; costs and benefits are not determined

Efficiency of conventional coal energy conversion technologies

Even with the latest technologies losses will be quite high

Major Social issues with conventional power plants• Peoples’ displacement will cause additional unemployment &

increase in slums

• Will affect agricultural production, and health ; fishing affected

• Prospect of displacement will create social tensions and stiff opposition

• Acid rains: Local buildings of heritage importance will degenerate

• Degradation of historical monuments ; temples, sculptures, heritage structures

• Leads to many Health issues; radiation issues• skin, lungs, heart, kidney

Major Environmental issues with conventional power plants• Pollution of air, land and water; hot water discharge into rivers/sea

• Will affect flora and fauna including forests • Potential for acid rain

• Very serious issues of Global Warming and Climate Change

• Coastal power plants will affect marine creatures

• High ash content in Indian coal - 30 to 40 %

• Ash disposal is serious; impact of fly ash on flora & fauna• only about 35% ash being used

• Traces of nuclear radiation in coal ash

• Sacrificing forests for coal mines ?

• Location of many coal plants destroying man-grove forests and wetlands

ASH POND OR ASH LAKE ?

EFFECTS OF ACID RAIN will DAMAGE vegetation(WESTERN and EASTERN GHATS at RISK?)

TN Power Scenario (April – October 2013)(Source: CEA)

Peak Demand - 13,380 MW (11,887 MW) > 11.2%

Energy - 55,564 MU ( 52,181 MU) > 6.1 %

For April 2012 - March 2013

Peak Demand - 12,736 MW (11,053 MW) > 13.2%

Energy - 92,302 MU ( 76,161 MU) > 17.5%

There is an inescapable need to manage the existing resources well:

Generating Plants &

Transmission and distribution network

Efficiency improvement, demand side management, and conservation should be

the future pathway

With this background

• Do we need many more large power projects?

• Must they be fossil fuel or large dam 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?

Energy efficiency improvement

T&D loss reduction; biggest source of DSM 10-15% savings feasible; 10,000 – 15,000 MW at national level

Improvement in agricultural pumping sets savings of about 18% in Karnataka

Usage of CFLs/LEDs in place of bulbs ; BEE’s estimation of savings: 10,000 MW

Efficiency improvement in end use applications Prayas Energy’s study: 30 % savings in households; corresponds to about

25,000 MW of avoided generating capacity

Demand Side Management AND Conservation

Economic necessities; reduces overall cost of installed capacity

leads to efficient usage of overall power system

lead to effective use of natural resources

ensures quality and equity of supply

unlimited demand leads to instability of grid

essential during times of power/energy shortage

reduces need for peaking stations (pumped storage plant)

Do we need many more of large generation projects ?

• How efficient is the Electricity Industry ?

• Are all our existing facilities being used optimally?

• Are we ensuring equity between urban and rural India?

• Can we reduce electricity demand without compromising the crucial economic and welfare activities?

• Is there a limit to reliable renewable energy sources?

• Can they be reliable and cost effective?

Electricity Industry Efficiency

• AT&C losses are about 35% {< 10% internationally, <13% in BESCOM}

• IP Sets consume about 38% of electricity; {about 50% of this wasted}

• Demand Side Management has huge potential; {about 15 to 20%}

• End use efficiency (non-agricultural sector) – 5 to 10%

• Domestic and industrial usages – 5 – 10 %

• Energy conservation – about 5 to 10%

All these put together can provide equivalent of 40 - 50% more virtual capacity OR save about 45% of the demand.

Deficit in TN and across country is about 10- 15%

Economic Implications

• @ Rs. 8 to 10 Crore/MW needed for additional generating capacity – huge burden on the state finances

• Other infrastructure areas like poverty alleviation, education and health are suffering due to reduced budget allocation

• State is known to be incurring more than Rs. 3,000 crores of loss each year

• As per 13th Finance Commission national level financial loss of ESCOMs could be

> Rs. 69,000 Crores in 2010-11 and > Rs. 150,000 Crores in 2014-15

Other concerns on conventional power plants

• Serious concerns about massive damage to the fragile ecology and bio-diversity

• No objective analysis of the real costs (both direct/indirect) to society and projected benefits

• Large quantity of fresh water will be required; stress on fresh water resources ( most states are already water stressed)

• Most coal fields are below thick forests

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.

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.

Efficiency, DSM and conservation will certainly help to overcome the shortages for next few years.

How can the future electricity demand be met ?

Can N&RE be an answer?

  Potential (Grid interactive power only)

1. Wind energy 50,000 MW (Onshore only) / (100,000 MW as per WISE) / 748,000 to 976,000 MW as per a recent study in 2011)

2. Small hydro 15,000 MW

3. Solar Over 5,000 trillion kWH/year Potential (estimated to be many times more than the total energy needs of the country) / (200,000 MW of

CSP as per WISE)

4. Bio-mass > 50,000 MW

5. Ocean based Energy

With about 7,000 kM of coastal line potential must be huge, but no estimates available

6. Geo-thermal Estimated to be considerable

N&RE potential in India(Primary Source: MNRE, Govt. of India)

Legitimate concerns with Renewable Energy sources

huge potential in N&RE in the country but the impact on environment have to be carefully managed.

widespread usage in distributed mode is critical roof top solar, community bio-mass, hybrids etc.

Many other benefits of distributed Res reduced losses, better voltages, more equity, rural employment etc.

Nature’s limit and material usage must be kept in mind

A typical case study

An identified need for 1,500 MW of additional demand--------------------------------------------------------------

Option I : 4,000 MW coal based UMPP by NTPC at Bijapur

COSTS: Direct Financial Cost : About 25,000 Crores + Foreign Exchange (Coal Import)

Societal Costs + tax incentives about 4,000 acres of agricultural land displacement of people perpetual loss of agricultural production 4 TMC of water from Almatty Dam? denial of the same to locals Huge quantities of coal supply & Mountains of Ash Air, water and land pollution Health costs; respiratory and neurological Social unrest & economic deprivation of poor people

BENEFITS : About 1,500 MW of dirty power Employment for100 people (?), mostly from outside the state Dividend to central govt.

Option II : Integrated Energy Management Approach

COSTS T&D loss reduction - 600 MW >> 900 Crores Utilisation loss reduction / DSM - 600 MW >> 900 Crores Wind energy - 100 MW >> 500 Crores Biomass – 50 MW >> 150 Crores Solar – Water heating – 100 MW >> 400 Crores Solar –residential lighting – 50 MW >> 1,500 Crores

Total cost (a high level approx. cost) >> 4,350 Crores

BENEFITS Negligible societal cost; negligible or nil land and displacement No recurring costs such as coal, water and chemicals Negligible or nil health or environmental costs Perpetual benefits Reduced T& D losses; reduced man power costs Boost to agricultural and rural employment

Net (MW) Comments

KKNP's capacity: 2 *1,000 2,000 The sanctioned capacity of 2*1,000 MW may go to 4*1,000 MW if the ongoing negotiations with Russia gets to fruition

Average annual power output possible (@ 60 - 80% annual load factor)

1,200 to 1,600

A power plant will not produce at 100% installed capacity at all times. Average annual load factor of the plant is assumed to be 60% though the Kalpakkam power plant (MAPS) has recorded load factor of 40-50% only during last 4 years.

Net average output possible to TN power grid {(Average annual power output) – (Station auxiliary consumption)(@ 10% of power output)}

1,080 to 1,440

10% Station auxiliary consumption assumed

TN's share in KKNP(50% of net power output: i.e 50% of 1,080 – 1,440 MW)

540 to 720 TN’s share assumed to be 50% from the plant

Net power available to consumers in TN (after allowing for transmission and distribution losses of 25%)

405 to 540 T&D loss in TN assumed to be 25%, as against national level loss of 25%.

If we also take the inefficiency in end usage of about 20% into account, the net power from KKNP available for productive/welfare usage

305 to 430 As per Prayas Energy Group survey about 20% of the losses in the end usage of domestic appliances are incurred.

True benefits of KKNP

Savings feasible from the existing power network

MW Comments

Benefits available by replacing all incandescent lamps in TN

>> 500 Power savings feasible by replacing all incandescent lamps in the country by CFLs is more than 10,000 MW

Savings feasible by reducing T&D losses in TN from 25% at present to about 10%

1,575 A saving of 15% of 10,500 MW (peak demand met by TN during April 2011 as per CEA report)

Savings due to loss reduction in end usage in various sectors of TN

1,575 Assumed to be about 15% of the actual power demand met, even though the potential for savings may be much higher

Benefits from Renewables

Wind power 700 Of the total TN potential of 5,500 MW capacity only 4,790 has been realized so far (as per TN energy department’s report).

Bio Mass 900 Estimated potential as per TN energy department’s report

Roof top Solar Photo Voltaic panels(2 kW each on top of 25 lakh houses)

5,000 Assuming 25% of strong houses in TN can install solar PV panels of 2 kW each on the roof top

Roof top Solar Photo Voltaic panels on other buildings

Huge

Benign alternatives available in TN

Sections 48 (a) and 51 (a) (g) of our Constitution

“ it is the duty of the STATE and every citizen to make honest efforts to protect and improve our environment by protecting and improving rivers, lakes, forests and living beings”

UN Convention on Biological Diversity (1992). “ … conservation of various components of biological diversity, the

sustainable use of its components, and the fair and equitable sharing of the benefits arising out of the utilisataion of genetic resources..”

The Precautionary Principle (UN Convention on Biological Diversity (1992). “ .. those activities which are likely to pose significant risk to nature shall be preceded by an exhaustive examination; their proponents shall demonstrate that the expected benefits outweigh potential damage to nature, and where potential adverse effects are not fully understood, the activities should not proceed.”

We need to honestly seek answers to:

What importance we, as a society, attach to forests and rivers ?

how much more of forests and how many more of rivers can be compromised?

have we considered the long term impacts of forest destruction at the present rate?

shall we not have the true interests of weaker sections of society at the centre of attention?

do we have any obligations to future generations?

are the various provisions of law just to be consigned to books?

Per capita consumption of electricity, water, petrol, paper have been highlighted for decades

Need to increase per capita consumption to that of world average also being advocated

But what about per capita forest land; per capita water availability ?

Per capita forest land in India is 0.10 hectares world average of one hectare Canada = 14.2 ha, Australia = 7.6 ha, U.S.A = 7.3 ha

Should this not be a primary concern ???

Way forward to protect the nature and vulnerable section of our society from the ravages of large size conventional power

projects

Attach appropriate value to all the natural resources in the country;

Declare all forests out of bound for power projects

Recognise the need to protect all forests in the country in order to preserve and develop

Consider electricity as national asset; it’s wastage should be heavily discouraged

Instead of GNP maximizing paradigm to estimate energy demand, we must estimate what is the least amount of energy needed to wipe out

poverty, and how best to meet it in a sustainable manner.

Adopt Costs and Benefits Analysis (CBA) as a mandatory part of approval process

Aim for achieving international best practices of efficiencies

Move away from large conventional power projects

Encourage widespread usage of distributed renewable energy sources

Effective demand side management, highest possible level of energy efficiencies, optimal levels of energy conservation, and widespread use of distributed

renewable energy sources must be our future action plan for power sector !!!

Effective Public Consultations is critical

CONCLUSIONS

30% of our households are still without electricity despite massive investments in 6 decades

Demand for electricity can be unmanageable if adequate care is not taken.

The so called balancing act between development and environment is an empty rhetoric having severely depleted bio-diversity during last 66 years.

Forest cover has come down from about 46% in 1947 to less than 23% and Rivers are being seriously threatened.

An honest commitment to protect the forests and rivers has become critical.

Human kind has lived without electricity for ages!

Can we live without a healthy environment ???

A healthy environment is critical for our survival.

An appeal

Let us focus on relevant issues from our society’s perspective only;

not from an individual or a company’s perspective!

keep the poor and vulnerable sections at the centre of our attention !!

constantly remind the society that without a healthy environment and social equity we are doomed !!!

As Gandhiji has said, every single public expenditure should be put to the yardstick

whether it benefits the last person in the society.

Best Wishes for a Green Planet

And

Thanks
