  1. 1. 1 Developing a PowerDeveloping a Power Market in IndiaMarket in India - A Transmission- A Transmission PerspectivePerspective
  2. 2. 2 • 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 INDIAN POWER SECTOR- A PROFILE
  3. 3. 3
  4. 4. 4 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
  5. 5. 5 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
  6. 6. 6
  7. 7. 7 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. 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 PLAN FOR NATIONAL GRID-A PHASED DEVELOPMENT

  13. 13. 13 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. 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
