• Indian Power Sector –

Installed capacity – 107,000 MW (Thermal-76%,

Hydro-23%, Nuclear-1%)

Peak Demand – 82,000 MW

Transmission lines - 5 Million Ckt. kms

Regional Grids – 5

National Grid under progress

Growth Rate of energy– 9% per annum

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

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

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

surplusEstimated 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

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
