Tripura Renewable Energy Agency (TREA) has adopted an ambitious plan for producing low-cost electricity. As part of the plan, one solar hybrid project has been installed on top of the Vigyan Bhavan recently. The project that was established at a cost of Rs 5 lakh is unique in nature as it uses both wind and sunlight to generate power. The project has been producing two-kilo watt power each day by using wind as well as Sun, said Subhash Chowdhury, Director of TREA here on Tuesday.
