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

54

WATER SUPPLY TO WATER SUPPLY TO BANGALOREBANGALORE

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
