TPDDL Solar Journey • Spearheading the Solar Initiatives, TPDDL pioneered in the ‘Demonstration Programme on Tail End Grid Connected Solar Power Plants’, an initiative of Ministry of New and Renewable Energy (MNRE), Govt. of India. TPDDL has commissioned eight (8) Solar Plants under this prestigious program • The most significant in TPDDL Solar Projects is the Mega Watt Class of Grid connected Solar Plant at its Central Stores at Keshavpuram, which is a unique project where dual utilization of land has been achieved by creating a roof top solar plant over a fully functioning open material store. • TPDDL has set up twelve (12) no. of 1 KW capacity standalone Solar lighting system in RWA Porta Cabins in New Delhi Municipal Corporation area under “My Delhi I Care” scheme of Govt. of Delhi.
