HYDERABAD: The Greater Hyderabad Municipal Corporation will replace the old street lights with power saving LED lights in Circle 10 in phases on a pilot basis. Of the 4.16 lakh street lights in Greater Hyderabad, 32,500 exist in the Circle 10 area covering Jubilee Hills, Banjara Hills, Ameerpet, Punjagutta, Begumpet, Khairatabad, Lakadikapul, Somajiguda, Balkampet, Sanjeevareddy Nagar and other places. LED lighting is expected to save up to 50 to 60 pc of energy consumption. At present, the 32,500 street lights are consuming 6.16 MW of power with consumption charges of Rs 18.07 crore.
If these are replaced with LED lights, the power consumption will come down to 2.65 MW with a saving of 3.51 MW and consumption charges will come down to Rs 7.79 crore with a saving of Rs 10.29 crore. The glowing will be 95 percentage. Installation of LED lights in the circle will be taken up by Energy Efficiency Services Limited (EESL), a joint venture of PSUs of the Union ministry of power. The total cost of the project will be around Rs 17.72 crore, GHMC officials told Express. LED bulbs are said to be the most energy-efficient, have a very long life, almost 15 to 20 times the ordinary bulbs and 8 to 10 times that of compact fluorescent lamp (CFL) and therefore provide both energy and cost savings in the medium and long terms. To quantify the conservation, a centralised control monitoring system (CCMS) will be installed. The street lights will be cointolled by CCMS with automatic on/off time. They said that discussions with EESL for modification of certain modifications are going on.
Maintenance of cable, switches, meters, fixtures, arms, poles, etc will be under the control of EESL and the warranty period for alltypes of damages will be covered under insurance by EESL. GHMC is incurring a huge expenditure on CC charges and maintenance of street lights and there is a need to cut down the expenditure by using the latest technologies such as LED lights. Due to improved technologies there will be about 50 to 60 percent energy saving with LED compared to conventional lighting. The advantages of CCMS is that currently manual on/off switching is done due to which lights keep glowing unnecessarily for about an hour. There will be automatic identification of failures, real-time control of any individual lamp, reduction in on-site maintenance costs, automatic generation of alarms and notification to operations managers and crew to optimise their maintenance schedules.
