• 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 linked to per capita consumption

Energy Consumption: Giga Joules per capita per year
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
3
POWER AND HUMAN DEVELOPMENTMagnified effect of increase in Energy Consumption on Human Development
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 POSITION IN INDIA
Fast Growth, but still substantial development needed in power sector
Power needs to be:
Environmentally sustainable, without compromising on economic and social development.
Affordable
Equitably accessible to all sections of society.

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

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

PEAK LOAD V/S BASE LOAD
Need for diverse Fuel-Mix

• 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’
Recent Developments and Other Initiatives
For Long-term Power Optimization
Energy Efficiency
• Gas Pricing Revision/Pooling of Gas prices• Plan to pool Imported and Domestic coal prices
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
Part Load operations
Significant logistics benefits are possible if domestic and imported coals are swapped between power plants.
Linkage rationalization
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
