  1. PRESENTATION ON “ Power Scenario in India ” by V.K. AGRAWAL GM, SRLDC BANGALORE 2nd March, 2006

  2. PRESENTATION OVERVIEW • INDIAN POWER SYSTEM – EVOLUTION • REGIONAL GRIDS IN INDIA – QUICK FACTS • SOUTHERN REGIONAL GRID – AN OVERVIEW • GRID CONTROL - ISSUES & CARDINAL EVENTS • POWER SECTOR - THRUST AREAS & CONCERNS

  3. INDIAN POWER SECTOREVOLUTION

  4. Indian Power Grid – its Evolution • Phenomenal expansion since Independence (1947) Generation : 1349 MW (in 1947) 120,000 MW (in 2006) • Grid : Local grid – at the time of Independence. State Grids – emerged in 1960s. Regional Grids – in 1970s. Five Regional Grids – Northern, Western, Southern, Eastern & North-eastern National Grid – All Five Regions Interconnected (2002)

  5. Growth of Installed Capacity for Electricity in India ALL FIGURES IN MW

  6. EHV Infrastructure

  7. Hydro Coal Energy Resource Map

  8. Source wise composition of installed capacity in India 1,20,934 MW

  9. ALL INDIA GENERATION COMPOSITION Total Market Size = 510.8 BU

  10. ALL INDIA MARKET COMPOSITION

  11. Sector wise consumption of electricity in India

  12. INDIAN POWER SECTOR - HIERARCHICAL SET UP State Govt. SERC IPPs SGC CPPs STU SLDC Distn Cos. Consumers Central Govt. CEA CERC RPC CTU RLDC CGS

  13. REGIONAL GRIDSQUICK FACTS

  14. REGIONAL GRIDS INSTALLED CAPACITY NORTHERN :- 33,782 MW EASTERN :- 16,680 MW SOUTHERN :- 33,162 MW WESTERN :- 34,867 MW NORTH-EASTERN :- 2,443 MW TOTAL 120,934 MW NORTHERN REGION NORTH-EASTERN REGION EASTERN REGION WESTERNREGION SOUTHERN REGION

  15. ‘ ELECTRICAL’ REGIONS 1 NORTHERN REGION NORTH-EASTERN REGION EASTERN REGION 2 WESTERNREGION 3 SOUTHERN REGION SAME FREQUENCY FROM GUJARAT TO ARUNACHAL PRADESH WITH EFFECT FROM MARCH 2003 ABOUT 2800 KMS! APART

  16. ‘ELECTRICAL’ REGIONS NORTHERN REGION 1 NORTH-EASTERN REGION EASTERN REGION WESTERNREGION 2 SOUTHERN REGION WITH THE COMMISSIONING OF THE TALA PROJECT CONNECTING THE EASTERN AND NORTHERN GRIDS, INDIA WILL HAVE ONLY TWO GRIDS

  17. Inter Regional Links 1650 MW 700 MW 1850 MW 900 MW 30,500 MW 2300 16,000 1200 MW 32,700 MW 1200MW Present IR Capacity = 9,500 MW 32,934 MW 2000MW

  18. By 2006 Inter-regional capacity - 11,500MW

  19. By 2007 Inter-regional capacity - 18,400MW

  20. NORTHERN REGION 11850 MW 5500 MW NORTH-EASTERN REGION 6050 MW 1200 MW WESTERNREGION 1400 MW 6150 MW SOUTHERN REGION INTER-REGIONAL TRANSFER BY END OF 11th PLAN (2012) 4000 MW EASTERN REGION 36,700 MW OF INTER-REGIONAL POWER BY 2012

  21. GROWTH OF INSTALLED CAPACITY OF SR IN MW Average Growth ~ 5 %

  22. INSTALLED CAPACITY IN SR The above capacity does not includes --- About 1344 MW of Wind Mill Capacity in Tamil Nadu. --- Micro and Captive plants in different states.

  23. SOURCE-WISE INSTALLED CAPACITY OF SR NUCLEAR IN MW WIND/OTHERS HYDRO GAS THERMAL 33,162 MW

  24. TRANSMISSION IN SOUTHERN INDIA ABOUT 2800 CKM OF 400 KV LINES ADDED IN THE PAST 2 YEARS

  25. TYPICAL LOAD CURVE OF SR SUMMER EVENING PEAK WINTER MONSOON WEATHER

  26. GRID CONTROLISSUES & CARDINAL EVENTS

  27. GRID OPERATION – TYPICAL ISSUES IN PAST • LOW / HIGH FREQUENCY PROBLEMS • FREQUENCY EXCURSES TO LOW/HIGH VALUES • LOW / HIGH VOLTAGE OPERATION • CRITICALLY LOW VOLTAGES AT LOAD CENTRES • SUBSTANTIALLY HIGH VOLTAGES AT FAR ENDS • SYSTEM BROWNOUTS / BLACK OUTS • SEPERATION OF SYSTEMS / LOSS OF LOAD • ECONOMIC IN-STABILITY / INCREASED ELECTRICAL LOSSES • UNRELIABLE / INEFFICIENT OPERATION OF EQUIPMENT ...THE END RESULT :

  28. GRID OPERATION: A TIGHT ROPE WALK POWER SWINGS INSTABILITY INCREASED LOSSES BLACK-OUT IN-ECONOMIC OPERATION VOLTAGE COLLAPSE

  29. GRID OPERATION –PRESENT STATUS • STABILISED SYSTEM FREQUENCY • IMPROVED VOLTAGES • MERIT ORDER OPERATION • INTER REGIONAL EXCHANGES • IMPROVED GRID SECURITY

  30. GRID PRESENT STATUS -- CARDINAL EVENTS • AVAILABILITY BASED TARIFF • UNIFIED LOAD DESPATCH SCHEME • GENERATION ADDITION • INTERREGIONAL AC / HVDC LINKS • OPERATIONAL EXELLANCE ...THESE EVENTS CHANGED THE FACE OF GRID OPERATION

  31. INDIAN POWER SECTORTHRUST AREAS AND ISSUES

  32. INDIAN POWER SECTOR – THRUST AREAS • SEBs TURNAROUND • DISTRIBUTION SECTOR REFORMS • EVOLUTION OF PLANS AND POLICIES • EMPHASIS ON SYSTEM SECURITY & STABILITY

  33. INDIAN POWER SECTOR – ISSUES • ADDITION OF TARGETED CAPACITIES • INTRA-STATE ABT • METERING AND BILLING • CONCEPT OF ANCILLARY SERVICES • RATIONALISATION OF UI SLOPE

  34. MONSOONS SOUTH WEST MONSOON NORTH EAST MONSOON BACK

  35. Power development - 16th EPS projections Peak requirement in MW Energy requirement in BU
