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

12. LANDMARK EVENTS  ADDITION OF GENERATING CAPACITY  TALCHER-KOLAR AND ASSOCIATED SYSTEM  UNIFIED LOAD DESPATCH SCHEME  TRANSMISSION SYSTEM AUGMENTATION  AVAILABILITY BASED TARIFF

13. IMPROVEMENTS IN GRID OPERATION  POWER SYSTEM PARAMETERS –FREQUENCY IMPROVED FREQUENCY IMPROVEDFREQUENCY IMPROVED –VOLTAGES STABLE ACROSS THE GRID VOLTAGES STABLE ACROSS THE GRIDVOLTAGES 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 MERIT ORDER OPERATION :- OPTIMISATIONMERIT ORDER OPERATION :- OPTIMISATION  HYDRO CONSERVATION HYDRO CONSERVATION HYDRO CONSERVATION –HEALTHY RESERVOIR LEVELS –USE HYDRO GENERATION FOR PEAKING AND RESERVE –PUMP MODE OPERATION AT KADAMPARAI PUMP MODE OPERATION AT KADAMPARAIPUMP MODE OPERATION AT KADAMPARAI  TALCHER – KOLAR LINK –INTER REGIONAL POWER :- 9770MUs/1600MW MAX  UTILISATION OF COMMERCIAL MECHANISM –TURNOVER OF 4402 MU ON UI WORTH 800 CRORES –COSTLY GENERATION REDUCED.

14. FREQUENCY PROFILE 2002, 2003 & 2004

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

16. WATER SUPPLY TO BANGALORE 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 PUMPING LOSSES REDUCED ENORMOUS SAVINGS TO THE STATE MOTOR BURNING AND MAINTENANCE COSTS ALSO CAME DOWN DRASTICALLY
