Renewable Power - Remote Sites

Mobile PhoneTransmission Towers


Repeater Towers Require Power Supply To Transmit

Rs.3 Lacs per km of power line extension

10 km = Rs.30 Lacs



Battery Diesel Generator

Annual Diesel use 17520 liters ( @ 16 hrs operation per day Rs.700000 per year – only fuel)



• Various Types of Repeaters – Different Power needs

• 500 to 600 watts 24 hours a day for 365 days = 14 Kwh / day

• 1800 watts 24 hours X 365 days = 48 Kwh / day
