KOLKATA: The transition of street lights from high-pressure sodium lamps to LED has cut down on Kolkata Municipal Corporation‘s electricity bill by nearly Rs 50 crore a year.

As the civic body continues the initiative to replace the remaining conventional street lights with energy-efficient LEDs, it has the potential to save up to Rs 100 crore per annum by 2025.

With energy saving at 52%, the LED installation reduced the electricity bill by over Rs 4 crore a month, an official said. Not just savings, the switch to LEDs had also improved street illumination and helped reduce accidents and crimes, he added.

According to a civic lighting department official, around half of the 3 lakh-odd street lights in Kolkata have already been installed with LEDs with the remaining 1.5 lakh set to be replaced by 2025.

“We have invested Rs 150 crore for the switchover of the city’s street lighting system in the past three years. Given the rate of savings, we should recover the invested capital in three years. Now, we have to change the remaining street lights to ensure complete energy efficiency in street lighting,” said a civic official.

The transition had started nearly a decade ago, when 300 LED lights were first installed in and around the KMC headquarters, including on SN Banerjee Road, in 2014. But the initiative gained pace in 2018 with the installation of LED street lights on most of the major thoroughfares.

Encouraged by the beneficial results of the street light conversion, officials have decided to invest more on the purchase of LED lights and cover all thoroughfares in the next three years.

Sources said the civic lighting department aimed to cover all major thoroughfares under the LED installation project. “We have already introduced LED street lights along over 60% of major thoroughfares. Now we will take up roads in KMC-added areas, such as Behala, Garden Reach, Tollygunge to Jadavpur, as well as some major roads in other parts of the city that are not covered yet,” said a civic official.

After installation of more LED lights, the civic body plans to do away with decorative lights as the LEDs will significantly increase the illumination level of streets.
