Solar Power generation is almost emission free. More the solar power we generate less is the emission. We may keep our commitment towards the Paris agreement aimed at climate change by producing more solar power”, says Dr S.P. Gon C.In 1994 households in the Kamalpur Village in the Sagar Islands of Sundarbans got electrified all thanks to the efforts of Prof Chaudhuri who introduced solar lighting system through the mini grid concept. Mini grid concept which was developed by Prof Chaudhuri for the first time is a local grid powered by solar energy or hybrid system. It is used as a cost-effective solution for electrifying rural communities where a grid connection is not possible.After extensive research and study, and funding from both central government (Ministry of New and Renewable Energy) and state government, Prof Chaudhuri set up the first mini grid power plant of India in early 1994.haudhuri, an Electrical Engineer and International Expert in the field of Renewable Energy. As India thrives to achieve its target of generating 100,000 MW (megawatt) solar power by 2022 to reduce its emission level within the prescribed limit, NDTV speaks to S.P. Gon Chaudhuri, the man who brought electricity to the remotest villages of India in 1994 by introducing solar lighting system.
He has has also received National Science Academy Award, Green Oscar from UK and Euro Solar Award from Germany for his outstanding contribution in providing energy access to millions of people on this planet.Talking about how solar power changed the life of the people of Sagar Island who were living in darkness for hundreds of years, Prof Chaudhuri says,After the success of mini grid power plant in Kamalpur village, over 2000 mini grid systems were set up in various parts of the country including West Bengal, Uttar Pradesh, Madhya Pradesh, Rajasthan, and North Eastern states.As part of the Swachh Bharat Abhiyan, nationwide cleanliness campaign initiated in 2014, toilets are being constructed in many villages, but due to lack of running water for flushing, toilets are becoming non-functional within few days of construction, reveals a survey done by Prof Chaudhuri.
Micro solar pump lifts water from the nearest water body or under the ground to the over head tank (OHT) installed above the toilets, ensuring running water. The cost of setting up one micro solar pump is Rs. 15,000. The innovator has installed 40 micro solar pumps, of which 30 are in girls schools.In addition to the solar water pump, another innovation from Prof Chaudhuri’s stable has been the Solar Water Purifier. It aims at providing clean drinking water and is an extension to Micro Solar Pump that pumps water and stores it in an OHT. Solar Water Purifier gets water from the OHT, removes suspended particles from the water, saving electricity. Initially, the technology was implemented in three schools and when they were convinced with the idea of fetching water and purifying it with the help of solar, it was extended to other schools. Currently, the innovator is providing solar water purifier to 100 schools in Tripura and Assam which will end up benefitting around 80,000 students. Of 100, 11 schools have already been covered.Madurdaha Aradhana Institute in Kolkata is one of the beneficiaries. Sharing the experience, Budhadeb from Madurdaha Aradhana Institute says,Since the water purifier runs on solar, it reduces dependence on grid electricity, hence low electricity bill.
Talking about how viable it is to switch to solar power, considering the finances, Prof Chaudhuri says, “Cost of solar generation is in the range of Rs. 3 per unit in comparison to Rs. 5 per unit for coal based power. Since solar is intermittent in nature, storage and backup conventional power are required. Solar energy price with storage is still high and is in the range of Rs. 10 per unit. Shifting towards solar energy will happen completely when cheap storage options for solar energy will be available. Such a transition may happen in next 10 years’ time. At 100 year of Independence, India will have a major solar power contribution in the energy basket.”Prof Chaudhuri believes that until and unless we provide benefits to poor and rural people and solve their problems, nothing can be achieved. He says there are three basic needs of rural people – drinking water, sanitation and electricity and all three can be addressed through solar.
