TALCHER POLE CAPABILITY TO BE ENHANCED TO 2500 MW GRID MAP TYPICAL FLOWS ARE FROM NORTH TO SOUTH GRID FOCAL POINT SHIFTED TO KOLAR AFTER COMMISSIONING OF HVDC QUANTUM CHANGES IN FLOW PATTERN LIKELY AFTER COMMISSIONING OF KOODANKULAM 2000 MW

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

  8. LINK TO FOLDER 3D DEMAND, LOAD CURVES HOURLY AVERAGE DEMAND AND FREQUENCY DATA

  9. ABT @ WORK

  10. AVAILABILITY BASED TARIFF A RATIONAL TARIFF STRUCTURE SCIENTIFIC SETTLEMENT SYSTEM …..COMPLEMENTS GRID SECURITY……RATHER THAN COMPROMISING IT !!!

  11. GRID OPERATION IN THE PAST • LOW FREQUENCY PROBLEMS • FREQUENCY REMAINED AT 48 HZ AND BELOW FOR MOST PART • LOW VOLTAGE OPERATION • VOLTAGE AT BANGALORE DIPPED TO AS LOW AS 300 Kv!!!! • FREQUENT GRID DISTURBANCES • A DISTURBANCE ALMOST EVERY MONTH • IMMENSE FINANCIAL LOSSES FOR INDUSTRY • LOADS FREQUENTLY CUT OFF DUE TO RELAY OPERATION • INCREASED ELECTRICAL LOSSES • INEFFICIENT OPERATION OF ELECTRIC EQUIPMENTS • GRID OPERATION FOCUSSED ON FIRE-FIGHTING RATHER THAN OPTIMISATION AND ECONOMY ...THE END RESULT : COSTLY AND LOW QUALITY OF POWER!

  12. LANDMARK EVENTS • ADDITION OF GENERATING CAPACITY • TALCHER-KOLAR AND ASSOCIATED SYSTEM • UNIFIED LOAD DESPATCH SCHEME • TRANSMISSION SYSTEM AUGMENTATION • AVAILABILITY BASED TARIFF ...THESE EVENTS CHANGED THE FACE OF GRID OPERATION

  13. IMPROVEMENTS IN GRID OPERATION • POWER SYSTEM PARAMETERS • FREQUENCY IMPROVED • VOLTAGES STABLE ACROSS THE GRID • OPTIMAL OPERATION • LOSSES REDUCED BY 1-1.5 % THROUGHOUT THE GRID • SAVINGS OF ABOUT Rs 450 CRORES EVERY YEAR! • MERIT ORDER OPERATION :- OPTIMISATION • HYDRO CONSERVATION • HEALTHY RESERVOIR LEVELS • USE HYDRO GENERATION FOR PEAKING AND RESERVE • PUMP MODE OPERATION AT KADAMPARAI • TALCHER – KOLAR LINK • INTER REGIONAL POWER :- 9770MUs/1600MW MAX • UTILISATION OF COMMERCIAL MECHANISM • TURNOVER OF 4800 MU ON UI WORTH MORE THAN 900 CRORES • COSTLY GENERATION REDUCED. UI ...THE END RESULT : AN EFFICIENT AND OPTIMAL OPERATED GRID

  14. FREQUENCY PROFILE 2002, 2003& 2004

  15. COMPARISION OF BANGALORE VOLTAGE-TYPICAL DAY 2003 2004 BETTER VOLTAGE PROFILE MEANS LESS ELECTRICAL LOSSES REALITY BITE: FARMERS IN KARNATAKA ARE HAPPY WITH FEWER HOURS OF QUALITY POWER!!. EFFICIENCY OF PUMPS AT TG HALLI WATER WORKS IMPROVED! 2002 NEXT: WATER SUPPLY TO BANGALORE CITY

  16. WATER SUPPLY TO BANGALORE PUMPING LOSSES REDUCED ENORMOUS SAVINGS TO THE STATE MOTOR BURNING AND MAINTENANCE COSTS ALSO CAME DOWN DRASTICALLY LOW VOLTAGE PROBLEMS AROUND BANGALORE HAMPERED WATER SUPPLY EARLIER WITH BETTER VOLTAGE NOW, PUMPING EFFICIENCY HAS IMPROVED 400 KV STATION AT MYSORE BEING COMMISSIONED ON WAR FOOTING TO FURTHER FORTIFY THIS PART OF THE GRID

  17. 600 300 150

  18. DEMAND Vs FREQUENCY FOR 30-JULY-04 FREQ DEMAND

  19. NEXT: BOXED UP UNITS

  20. MERIT ORDER : UNITS BOXED UP

  21. OPTIMAL RESERVOIR UTILISATIONLINGANAMAKKI IN KARNATAKA MORE THAN 400 MILLION UNITS OF ENERGY SAVED DUE TO IMPROVED OPERATIONAL EFFICIENCY AND OPTIMISATION THIS IS WORTH Rs 80 CRORES ENERGY STORAGE IN MU (THIS YEAR) :- 3524MILLION UNITS ENERGY STORAGE IN MU (LAST YEAR) :- 2356 MILLION UNITS

  22. KADAMPARAI UNITS OPERATION ON A TYPICAL DAY GEN MODE PUMP MODE

  23. UI DETAILS

  24. SUMMARY OF UI – 84 WKS(FROM 01/JAN/03 TO 08/AUG/04) IRE NEXT

  25. INTER REGIONAL UI IN SR (FROM 01/01/03 TO 08/08/04) • TOTAL UI TURNOVER :- 4831 MU • TOTAL UI AMOUNT DISBURSED:- 917 CR • INTER REGIONAL UI:- +942 MU (-)191 MU • AVG WEEKLY TRANSACTION:- 57 MU • AVG WEEKLY UI AMT DISBURSED:- 11 CR • AVG RATE OF UI WITH WR IN PS/U • 155 PS/U @SR • 255 PS/U @WR • AVG RATE OF UI IMPORT FROM ER IN PS/U • 144 PS/U @ ER MORE-IRE NEXT

  26. INTER-REGIONAL EXCHANGES A/C DETAILS UPTO 84 WKS (TILL 08/08/04) • SR IMPORTED 295 MU AND EXPORTED 181 MU TO WR. • AMOUNT ACCRUED IN SREB – IRE DUE TO DIFF. IN WR A/C = 36.5Crs • AMOUNT ACCRUED IN WREB – IRE DUE TO DIFF. IN SR A/C = 23.25Crs • AMOUNT DUE TO SR CONSTITUENTS ON 50:50 BASIS = 29.83Crs • 100 % DISBURSEMENT
