Greater Hyderabad Municipal Corporation\'s initiative to replace the conventional street lighting system with light-emitting diodes (LED) across the city is likely to save a whopping Rs 100 crore in power bills to the civic body. These LED lights not only provide better illumination but also reduce electricity consumption by 50 percent. 

Hyderabad: Greater Hyderabad Municipal Corporation's initiative to replace the conventional street lighting system with light-emitting diodes (LED) across the city is likely to save a whopping Rs 100 crore in power bills to the civic body. These LED lights not only provide better illumination but also reduce electricity consumption by 50 percent.

Last year, the civic body installed about 750 LED street lights along various stretches in Madhapur and Chandrayangutta areas on a pilot basis. GHMC mayor Bonthu Rammohan said, about 32,000 street lights in the city would be replaced with LED lights in the central zone in the first phase. Overall, as many as 4,13,029 streetlights in the city would be replaced in a phased manner.

Officials have been asked to prepare a detailed project report to replace the remaining street lights in the city and send it to the State government for approval. The existing sodium vapour lamp street lights in the city consume about 60 mw of power and the corporation has been spending about Rs 190 crore to maintain them. Currently, GHMC has been consuming about 20 million units of electricity per month.

Of the total 4.13 lakh street lights, about 2,07,793 are 150w high-pressure sodium vapour (HPSV) lights. Other types of lights include 250w HPSV (73,215), 70w HPSV (47,520), and 40w tubes (16,475), 250w MH (16,536), 400w MH (18,150), 120w LEDs (254) and 250w Induction (4).

The estimated cost of the project would be about Rs 500 crore. The Mayor said that an extensive study would be conducted to replace the existing street lights with bulbs of different wattage (like 20W, 40W, 70W, and 120W) based on the width of the road. The GHMC Engineering Wing official said that under the project, the capital investment would be met by the Energy Efficient Services Limited (ESSL).

The main objective of the ESSL is to implement energy-efficient projects on a turnkey basis with the assistance of urban local bodies and state government. The project also covers replacement warranty of street lights and free operation and maintenance depending on the tenure. A centralised monitoring and control system would also be put in place, he added.

Meanwhile, GHMC has been spending Rs 190 crore annually towards the street lighting in the city. Specifically, the civic body has been spending Rs 125 crore towards electricity bills, Rs 10 crore towards salaries, Rs 15 crore for purchasing materials and Rs 35 crore for carrying out minor repairs.
