The State has been able to harness 40% of its energy requirement from renewable energy and with breakthrough technology expected in a few years in energy storage, it would not be hard to absorb more green power, said M. Saikumar, chairman and managing director, Tamil Nadu Generation and Distribution Corporation (Tangedco). Inaugurating a solar plant at the Vivekananda Cultural Centre on Kamarajar Salai on Friday, he said in the next two years, the State would be adding more than 3,000 mega watt (MW) of renewable energy through solar and wind plants. Congratulating the office-bearers of the Sri Ramakrishna Math, which manages the Vivekananda Cultural Centre, Mr. Saikumar advised the math to opt for the off-grid option by installing batteries. The Vivekananda Cultural Centre, where the Vivekanandar Illam is housed, has installed the power plants of 10 kilo watt (KW) and 20 KW capacity to power the two premises. They were established at a cost of 40 lakh. Swami Gauatamananda, vice-president, Worldwide Ramakrishna Math and Mission, said the solar plant was sponsored by Sundaram Finance and their group of companies. Santhanam Ram, chairman, Wheels India Limited, and S. Mahalingam, chairman, City Union Bank, participated at the inauguration function.
