POWER FOR NATION’S GROWTH
Power – The key driver for a Nation’s Economic Growth
Growth

Capacity
• For the country to grow at
accelerated rate, proportionate
growth of Power Sector is
necessitated
• With the govt.’s focus on
Manufacturing Sector as the
driver of growth, Power Sector
assumes high Importance

 Human Development Index (HDI) found to be
directly correlated to per capital electricity
consumption
 For countries like India, lying at low level of
development, even a small increase in electricity
use is associated with large increase in HDI

POWER POSITION IN INDIA
Fast Growth, but still substantial development needed in power sector
 10th largest economy in the world by nominal GDP; 3rd largest by GDP in PPP terms
 Second fastest growing economy
 Accounts for 4.1% of world’s energy consumption
 4th largest energy consumer ; fast moving to reach 3rd position by 2025

Energy demand in India will continue to grow rapidly over the next couple of
decades due to:
 Rapid rate of growth
 High urbanization levels
 An aspiring and growing middle class and a generally modernizing society

POWER: PROJECTIONS AND OBJECTIVES
Projections suggest a strong need to augment the capacity
Projected Installed Capacity (GW)
Acc. To
World Energy
Outlook, 2013
 Power needs to be:
 Environmentally
sustainable, without
compromising on
economic and social
development.
 Affordable
 Equitably accessible to
all sections of society.

SUPERIOR PERFORMANCE OF BHEL SETS IN INDIAN MARKET
BHEL manufactured sets clocked higher PLF than national avg.

35 coal based sets register PLF over 90%

79 coal based sets achieved PLF between
80-90%

166 coal based sets clocked uninterrupted
operation for more than 90 days – testimony
to BHEL’s product excellence

178 coal based sets achieved an operational
availability (OA) of higher than 90%

11 of 13 power station awarded ‘National
Awards for Meritorious Performance’ by MoP,
GoI, during 2012-13 are completely or partly
equipped with BHEL make sets

DEVELOPING NEW TECHNOLOGIES
Constantly innovating to cater future demands
Development of Fuel Flexible Supercritical Boilers
New Boiler design capable of firing both extremes - from 100% domestic coal
to 100% imported coal to effectively deal with uncertainties over availability of
domestic and imported coals
Development of Ultra Supercritical (USC) power plants
To improve steam parameters, thereby improving efficiency and heat rates,
resulting in reduced coal demands
Higher parameters provided for NTPC’s North Karanpura Project - country’s first
Super-critical power project with Air Cooled Condenser , and is taking strides
towards providing further improvements in parameters in the future
11
Advanced Ultra Super Critical Power Plant Project
Constantly innovating to cater future demands
BHEL, NTPC and IGCAR working together in a national consortium for indigenous development
and commissioning of 800 MW Advanced Ultra Super Critical (AUSC) Power Plant in India
Targeted operational parameters :
• 7100 Celsius, 310 Bar, Plant efficiency 46% leading to Reduction in Coal consumption and CO 2 emission
by 12% as compared to Super Critical plants
Project planned in two phase :
• R&D phase for Two and Half years and Manufacturing and Commissioning in next four and half years
Challenges involved are Development of New Alloy Materials, Manufacturing Technologies :
• Casting/ forging/ machining and welding, Assembly, Testing procedures and site commissioning
R&D Project cost estimated at Rs. 1554 Crs:
• GOI funding of Rs. 1100 Crs and balance 454 Crs by BHEL and IGCAR (BHEL : 220 Crs and IGCAR : 234
Crs)
Union Budget 2014 Speech:
• Hon’ble Minister of Finance has indicated allocation of Rs. 100 Crs for 2014-’15 for this R&D project

PEAK LOAD V/S BASE LOAD
Need for diverse Fuel-Mix

Coal Based Plants can cater to Base Load

High Peak Demand Deficit

Need for Peaking Plants with faster start up

Gas-based plants preferred for this

Added Advantage: Cleaner fuel than coal
14
Recent Developments and Other Initiatives
For Long-term Power Optimization
• Gas Pricing Revision/Pooling of Gas prices
• Plan to pool Imported and Domestic coal prices
Linkage rationalization
Significant logistics benefits are possible if domestic and imported coals are
swapped between power plants.
Part Load operations
Power Plants in the Country are optimised to operate on full load and Part load
operations should be avoided.
Running number of plants on part load, operating some of the by turn on full load
and sharing the load would be a better option
Energy Efficiency
• Another source of energy which is affordable but under-exploited
• No adverse environmental impact
• Shift from ‘austerity’ focused ‘energy conservation’ to technology driven ‘energy
efficiency’ to ‘energy productivity’
15
CONCLUSION
 The Best energy strategy:
 Adopt a holistic and national power strategy
 Optimally develop domestic resources
 Deploy better technologies
 Adopt tariffs that accurately reflect fuel costs
 Reduce subsidies
 Minimize exposure to commodity prices by diversifying generation mix,
and
 Implement the right policies that will ensure that the path to progress
remains brightly lit
