KOLKATA: The Bidhannagar Municipal Corporation is awaiting financial approval from the state government to implement the Rs 20 crore project to wrap up all the 41 wards of the civic body, including Salt Lake with LED streetlights, replacing the old sodium vapour lights.
“We have placed the proposal before the government and expecting it to be cleared very soon. The plan is to replace all old sodium vapour lights with LED lights,” said Bidhannagar board of administrators member Sudhir Saha, adding that LED streetlights have already been installed in some stretches of the township.
Residents have been complaining for a long time that there are many stretches in the township, which are inadequately lit and becomes dark after sunset.
“Many places in Salt Lake have poor streetlights, specially on the stretches inside several blocks. The plan to install LED lights because it is not only environment friendly and brighter but also saves a lot of electricity bill,” said Tamal Pal, a resident of HB block.
Presently there are about 25,000 sodium vapour lights across Salt Lake and adjacent areas, which will be replaced with LED lights, officials said. As per rough estimates, the civic authorities pay a monthly energy bill of about Rs 1.5 crore. “About 60% of the electricity bill will get reduced once all the streetlights are covered with LED,” said a civic official.
Officials said that the LED lights will have chip-based sensors and timers, which will automatically turn on the lights once the natural light fades out.
The civic authorities will be able to monitor each and every streetlight from its control room and will receive a signal if there is any technical glitch in any of the lights.
