  13. ADVANTAGESINTER-REGIONAL UI • WIN – WIN PLATFORM – PROMOTES TRADE • SPOT MARKET IN REAL TIME • REDUCES THE NEED FOR BILATERAL • BEST UTILISATION OF FLEXIBLE HYDRO • COSTLIER GENERATORS IN SR • CHEAPER PIT-HEAD STATIONS IN ER • SR IS ENERGY DEFICIT • ER IS ENERGY SURPLUS • SHORTAGE OF COAL / LIGNITE IN SR • IMPACT ON ENVIROMENT • REPLACE COSTLY GENERATION BY CHEAPER GENERATION • ULTIMATE ECONOMISATION

  14. ER –SR LINK PRESENT • 500 MW GAJUWAKA HVDC B2B • 2000 MW TALCHER-KOLAR HVDC FUTURE • ANOTHER 500 MW HVDC B2B AT GAJUWAKA BY DECEMBER 2004 • ENHANCEMENT OF TALCHER-KOLAR HVDC TO 2500 MW BY NEXT YEAR DIAGRAM

  16. SCHEDULING AND METERING POINTS OF ER – SR UI TALCHER STAGE2 ER TALCHER SCHEDULING & METERING POINT EAST BUS ER INTERCONNECTOR TALCHER HVDC GAJUWAKA HVDC SOUTH BUS SR

  17. UI ON ER –SR LINK • FLEXIBILITY TO THE SYSTEM OPERATOR • MERIT ORDER • OPTIMISATION OPPORTUNITY • LOSS REDUCTION • DE-CONGESTION OF NETWORK • RAIPUR-ROURKELA IN ER • BHILAI-KORADI IN WR • CUDAPAH-KOLAR, NUNNA-NELLORE IN SR • VOLTAGE CONTROL • FGMO – MORE CONDUCIVE

  18. PRESENT ER –SR UI • ER UI IS CALCULATED BASED ON THE ER FREQUENCY • ONLY ONE SIDE FREQUNCY IS USED • NO SHARING OF BENEFIT BY THE EXPORTING ER REGION • UNLIKE PRACTICE IN OTHER REGIONAL LINKS

  19. PRESENT ER –SR UI DIFFERNCES BETWEEN ER-SR LINK AND OTHER INTER REGIONAL LINKS • TALCHER STAGE2 BELONGING TO SR IS PRESENT IN ER • TALCHER – KOLAR HVDC LINE IS PART OF SR TRANSMISSION SYSTEM • LOSS AND TRANSMISSION CHARGES OF TALCHER KOLAR LINE IS BORNE BY SR.

  20. GLORIOUS CASES (01-04-03 TO 08-08-04) DATE UI FROM ER INMW 21-09-2003 980 25-09-2003 1060 19-05-04 1100 9.1MUs AVAILED FROM ER/WR UNDER UI ON 31/AUGUST/03 ------850MW.

  21. SECURITY INADDITION TO THE ECONOMICS, THE SECURITY OF THE GRID IS ENHANCED BY INTER REGIONAL UI • DURING CRISIS BOTH THE REGIONS EXCHANGE THE UI POWER WHICH RESULT IN BETTER SECURITY OF BOTH THE GRIDS

  22. SUGGESTION • WHILE ARRIVING THE RATIO FOR SHARING THE BENEFIT THE FOLLOWING HAS TO CONSIDERED • CHANGING OF SCHEDULING/METERING POINT • TALCHER –KOLAR LINE LOSS • TRANSMISSION CHARGES OF TALCHER – KOLAR LINE

  23. SUGGESTION • INSTEAD OF INTERCONNECTOR OF TALCHER 1 & 2 , TALCHER HVDC CAN BE MADE SCHEDULING AND METERING POINT. • TALCHER STAGE 2 WILL BE IN THE ER POOL FOR UI ACCOUNT.

  24. TOTAL PAYABLES AND RECEIVABLES (01-04-03 TO 08-08-04) • TOTAL PAYABLES Rs. 876.21 Crores • TOTAL RECEIVABLES Rs.824.78 Crores • SAVINGS DUE TO ER UI GOES TO ONLY OVER DRWAING CONSTITUENTS. PAYABLES AND RECEIVABLES

  25. HIGHLIGHTS OF UI TRANSACTION ON 31.08.03 (SUNDAY, GANESH CHATURTHI) • UI imported from ER : 6.07 MU • UI imported from WR : 2.81 MU • Total UI imported from C. Grid by SR : 8.88 MU • Average UI rate of C.Grid : 93 Ps/Unit • Average UI rate in SR for C.Grid : 213 Ps/Unit • Max. Power transfer in UI from ER : 510 MW • Max. Power transfer in UI from WR : 350 MW • Total Max. Power transfer in UI from C.Grid: 860 MW • Amount saved for the SR constituents : 107 Lacs • Total Number of HVDC Operations : 50 no.s NEXT

  27. INTER-REGIONAL ARBITRAGEHOW IT WORKS FREQ = 50.2 HZ/ RS 0.70 WESTER REGION GRID EASTER REGION GRID SOUTHERN REGION GRID DIFFERENCE IS RS 1.50 SIGNAL:- DRAW POWER FROM CENTRAL GRID FREQ = 49.6 HZ/ RS 2.20

  28. HOW ARBITRAGE HEELPS • TAKES CARE OF EXIGENCIES • LOW FREQUENCY • HIGH FREQUENCY • KEEPS PRICE/FREQ MOVING IN A NARROW BAND • HELPS CONTROL CONGESTION • DECREASE LOSSES • MERIT ORDER OPERATION IN BOTH REGIONS EXTRACTS FROM NEMMCO
