Delhi to use Hi-Fi system for its streetLighting

The Municipal Corporation of Delhi (MCD) has decided to do its bit for the environment by adopting a remote-controlled street-lighting system. This means the streets of Delhi would light up automatically at dusk and it would be lights-out after sunrise.

The system is sub-geography specific, so south Delhi wouldn't waste unnecessary power when it's dusk only in Noida.

All the lights are individually monitored and controlled from a central server. In the event of a fault, an SMS is directly sent to the maintenance staff for speedy and timely action.


The system provides the report of operative and non-operative lamps on the roads.That's not all; this intelligent system can also detect any theft of power from the feeders.

"The system is based on Global system for Mobile communications (GSM) and General Packet Radio Services (GPRS) on which the mobiles work. While the system eliminates manual or timer-based operation of street lights, the lights are automatically turned on and off according to the sunrise and sunset time of the geographic locations." said municipal commissioner KS Mehra.

"This in turn is doing energy conservation and reduces carbon di-oxide emissions. The operation of streetlights is managed from a central station," he added.

MCD is upgrading the streetlights in two phases. The first phase covering 101 km has been successfully completed.  In the ongoing second phase, 157 km are to be covered. The entire cost incurred in the project is Rs 32 lakh.
