Kolkata Gets Solar StreetlightsBy siddharth22, Section Development
Kolkata today became the first city in the country to have streetlights powered by solar energy. The stretch between Chingrighata and Dhapa on E M Bypass was illuminated by 22 solar streetlights. The lights will automatically get switched on at sunset and will go off during the day hours.
The Left Front government has hired a US-based company, SOL Inc, to implement the project, said S P Gonchowdhuri, Director of West Bengal Renewable Energy Development Agency (WBREDA). He added, "The Salt Lake area of the city will be the maiden urban sector to have solar streetlights in India. We have roped in SOL India Pvt Ltd, which is the Indian branch of the American company, SOL Inc for implementing this project." Cold Cathode Fluorescent Lamps (CCFL) is being used for lighting. Soumitra Sen, the company's representative in eastern India, said: "We are using 32 watt bulbs which are fully controlled by a computer." "It will be concentrated lighting unlike the pre sent scattered ones," said Gonchowdhuri. He added in case of a very cloudy weather, the solar lights will be effective for three full days, and they will work for five days during partially cloudy weather. By Monday, 30 solar streetlights will be operational, said the director of WBREDA.
At present, the solar streetlights have been put up on one side of the EM Bypass and if all goes well WBREDA has plans to install them on both sides of the street. They are also keen on using solar en ergy for lighting other streets of Kolkata.
A sum of Rs 12 lakh was spent on the project with both the Central and state govern ments sharing 50 per cent of the cost. KMC too has similar plans. "We have floated a ten der for 100 poles for a stretch of 1 km- they will put up on Dhapa's Khana Beria road, under ward no 58," said Sushil Sharma, a KMC official.
