FUTURE POWER SUPPLY SCENARIOFUTURE POWER SUPPLY SCENARIO
• Peak demand (expected)- 157,000 MW
• Capacity Addition envisaged-100,000 MW in
next 10 years
• Goal – Power for all by 2012
BY THE YEAR 2012

NEED FOR NATIONAL GRIDNEED FOR NATIONAL GRID
 Uneven disposition of Natural resources
- Coal reserves concentrated in Eastern region
- Hydro potential mainly in North Eastern & Northern
region
 Establishment of large sized pit head stations to achieve
economy of scale
 Load Centers located at distant locations in Northern,
Western & Southern regions
 Constraints on Right-of-Way (ROW)
 Flexible & high capacity transmission system required for
power transfer to different regions

Phase – 1 – Already completed
• Interconnection of Regional Grids through HVDC Back-to-Back links
having cumulative capacity of 5000 MW
Phase – 2 – Partly completed
• Hybrid system comprising of high capacity HVDC and HVAC lines (both
765 kV and 400 kV)
 2000MW, 1400kms long HVDC bipole between Eastern and Southern
regions – completed
 400kV synchronous interconnections between Eastern and Western
regions resulting into synchronous operation of power system having
50,000MW capacity – completed
This will transfer operational surplus and would provide flexibility in
inter-regional transfer of power
• Present cumulative capacity is 8000 MW
• On an average, 1500-2000 MW is being transferred and about 35 MU/day
is being traded
PLAN FOR NATIONAL GRID-A PHASED DEVELOPMENT

8. 8
Phase – 2
• Most of transmission lines would be part of associated transmission
system of large sized generation project.
• Cumulative inter-regional capacity would be 23,000 MW
Phase – 3 – to be completed by 2012
• Ring of 765 kV transmission lines inter-connecting ER, WR and NR
• Cumulative capacity would be 30,000 MW
• This would be utilised for transfer of short term as well as long term
surplus
Estimated Investment : US$ 20 billion
– POWERGRID’s Investment : US$11 billion
– Private sector Investment : US$9 billion
This will facilitate development of power market

Major Issues & Suggestions
Issues
• Uncertainty in Generation Addition
• Mobilisation of Funds
• Recovery of Investment
• Proper Energy Accounting System needs to be evolved to
take care of unscheduled power transfer
• Accounting of transmission losses in different conditions
• Wheeling charges to different owners

14. 14
Major Issues & Suggestions
Suggestions
• Creation of Transmission Highways from resource
pockets to load centres, without linking them to a
particular generation project
• Special methodology need to be adopted for recovery
of transmission charges of Transmission highways
• Most important is that there should be long term
commercial agreement to enable huge investment in
transmission sector
