TN may get floating solar plants to check evaporation in dams
In a first, the State has proposed to set up 250mw floating solar power plants at a cost of Rs 1,125 crore which would help arrest water evaporation from reservoirs besides increasing Solar Purchase Obligation (SPO). A new Energy Policy will be chalked out by the state in tune with the Vision 2023 document.

Chief Minister Edappadi K Palaniswami who made a suo motu statement, informed the House that these projects would be constructed based on a feasibility study, and would be jointly undertaken by the Tamil Nadu Generation and Distribution Corporation (TANGEDCO) and Indian Renewable Energy Development Agency Limited (IREDA).
Floating solar plants have better efficiency compared to conventional ground-mounted or roof-top solar installations due to the moderating effect of water bodies on panel temperature. Kerala, at present, has a floating solar power plant installed in Banasura Sagar Dam in Wayanad with the capacity of 260mw, commissioned last year.
“The State would tweak its ‘Solar Energy Policy 2012’ in a way to increase Solar power generation to 8,884 mw in 2023.
With this the aim of state’s Vision 2023, Solar Energy Policy 2012 and National Solar Mission would be integrated,” Palaniswami said.
Modernisation of Moyar Hydroelectric Power station would be taken up at a cost of Rs 67.05 crore, which would see increasing power producing capacity to 3 times 14 mw from 3 times 12 mw and the power station’s life by 25 years.
“A new Energy Policy would be developed in consonance with high economic and social policies as envisaged by the Vision 2023 document,” the CM added.
Rs 5,068 crore for 25 sub-stations
Palaniswami said the government would set up 25 sub-stations at a cost of Rs 5,068 crore for better evacuation of solar, wind, thermal and hydroelectric power. A 400 kv substation in Tirunelveli would come up to evacuate solar and wind energy generated in the district, three sub stations of equal capacity would come up as one each in Neyveli (Cuddalore), Konthakai (Sivaganga) and Parali (Coimbatore). A similar capacity sub-station would be setup in Ottapidaram (Thoothukudi) which would be used to evacuate power from unit 1 of Udangudi thermal power plant 2 X 660 mw thermal power station, among others. To improve Chennai’s power infrastructure, six substations each having a capacity of 230 kv would come up at Ganesh Nagar, and KK Nagar in Chennai, Avadi and Ennore in Tiruvallur, Maraimalai Nagar and Pallavaram in Kancheepuram.
