The Guwahati Smart City Limited (GSCL) will soon start a project to light up arterial roads of Guwahati eplacing all streetlights with LED lights.
GSCL conducted a thorough survey of all the roads of the city and has decided to improve the arterial roads covering a length of 137 km.
The approximate number of electric poles along with lights likely to be needed for the purpose is 6,400. Roads of 7m, 9m, 10m, 12m, 15m and 20m width have been considered for the purpose.
A GSCL statement said that LED lights will be installed along selected roads and the LED lights will be mounted on proper poles and controlled by a smart centralised control and monitoring system (CCMS) which will be provided. The CCMS shall enable group on-off control and dimming on roads having fittings with ratings more than or equal to 90W.
Under the CCMS, there will be three types of control systems where all the bulbs rated below 90W will be operated in groups without any dimming, reports The Assam Tribune.
The LED bulbs below 90W will be operated either based on an astronomical timer or will be pre-programmed.
However, bulbs equal to or above 90W will be controlled in groups with dimming features at non-peak hours where automatic remote on-off along with dimming control based on timing or geographical location will also be available in the system.
The CCMS feature will reduce energy consumption and improve the level of visibility on the streets .
For implementing the project, the GSCL has already issued a notice seeking public opinion and the work will start next year.
The drawbacks of the existing lighting system in the city are higher operating cost, no real –time monitoring system to ensure performance and difficulty in maintenance.
According to sources, around 85 km of spine roads have been provided with LED streetlights.
